Chapter 19: Substance-Related & Addictive Disorders

Welcome back to The Deep Dive.

Um, I have to be honest, when I first picked up the reading for today, I was really expecting a lot of chemistry.

Right.

Yeah.

The molecular structures and all that.

Exactly.

You know, receptor sites, dopamine pathways, and I mean, we're definitely going to get to all of that, but the very first thing that hit me in chapter 19 of Essentials of Psychiatric Mental Health Nursing wasn't a chemical formula at all.

It was, uh, it was actually a definition of spirituality.

It completely catches you off guard, doesn't it?

It really does.

It defines spirituality as the state of wholeness, like a connection of mind, body, and spirit, and then it immediately positions addiction as the complete opposite of that.

It's a stark contrast.

Yeah.

It's not just about breaking the law or, you know, ruining your liver.

It's about isolation.

It's about a literal fracture in that wholeness.

That is such a crucial place to start.

And honestly, I'm so glad the text leads with it, because if you just look at taking too many pills,

you completely miss the human tragedy of it.

Addiction is a disease of isolation.

It cuts you off from your community, your family, and eventually from your own sense of self.

So when we talk about nursing care in this chapter, we aren't just trying to fix a chemical imbalance, we are trying to repair a broken connection.

And this isn't exactly a new struggle for humanity, is it?

I mean, the text throws out a date, 8 ,000 BC.

Yeah.

The era of Mead.

Fermented honey.

So people have been trying to alter their consciousness since we were basically living in caves, but the text makes a pretty terrifying distinction about what's happening right now in the modern era.

It's the chemistry.

Back in 8 ,000 BC, you had natural fermentation.

It takes time and there's a hard limit to how potent it gets.

Today, modern chemistry allows us to synthesize substances that are just exponentially more toxic and addictive.

That's a whole different ball game.

Exactly.

We aren't just dealing with strong wine anymore.

We are dealing with compounds that are specifically designed to hijack the brain more efficiently than anything nature ever could have created.

That phrase right there, the hijacked brain.

That is really the core theme of our deep dive today.

We are breaking down chapter 19, substance -related and addictive disorders.

And look, for everyone listening, this is a seriously dense chapter.

Oh, it is the heavy lifting of psychiatric nursing without a doubt.

It really is.

It's got massive tables of drugs, lists of withdrawal symptoms,

complex ethical dilemmas.

So our mission today is to translate that textbook density into something you can actually use and visualize.

And we are going to stick strictly to the text.

Yes, strictly to the text.

Whether you are a nursing student prepping for the NCLEX or just someone trying to understand why a loved one can't simply stop using, we're going to walk through the neurobiology, the specific drug classes and the nursing process as laid out in the book.

And we really want to spend a good amount of time on the clinical application.

It's one thing to memorize that alcohol causes a cyamine deficiency for a test.

It's a completely different thing to understand what that actually looks like when a patient is sitting right in front of you.

Definitely.

But before we really dive in, we should probably throw out our standard disclaimer.

Yes, we are strictly summarizing the evidence -based care and frameworks presented in chapter 19 of Essentials of Psychiatric Mental Health Nursing.

This isn't medical advice and we aren't bringing in outside theories or practices.

We're just here to help you unpack the material in the book.

Okay.

Let's start at the foundation, the actual definition of the problem, because I feel like in pop culture or even just talking at the dinner table, people use the word addiction really loosely.

All the time.

Like I'm addicted to chocolate or I'm addicted to this new show.

But clinically, according to the American Psychiatric Association cited in the text, it's much more specific than that.

It is.

The APA defines it as a chronic relapsing brain disease characterized by compulsive drug seeking and use despite harmful consequences.

Every single word in that definition is doing heavy lifting.

The phrase brain disease is usually the part that starts arguments, right?

Because a lot of people out there still see addiction as a choice, a really bad choice, sure, but a choice.

And that is exactly what the text refers to as the moral failing myth.

The authors tackle this head on.

Society so often views drug use as a lack of willpower or a character flaw or just someone being weak.

Right.

The whole just say no mentality.

Exactly.

Right.

But when you actually look at the imaging, when you look at the neurobiology, the brain of an addicted person has structurally and chemically changed.

It is a literal disorder of the reward circuitry.

So telling someone with this disorder to just use willpower to stop.

It's like telling someone with diabetes to just use willpower to regulate their insulin levels.

The actual biological mechanism that handles willpower, the frontal cortex is compromised.

The text also points out a shift in language that I think is really important for students to catch.

The DSM five doesn't even use the word abuse anymore.

No, and honestly, good riddance substance abuse carries so much baggage.

It sounds incredibly judgmental.

It implies that you are actively maliciously trying to hurt something.

The new clinical term is substance use disorder or SUD.

It definitely feels softer, but is it just being politically correct?

It's being clinically accurate.

It aligns addiction with other chronic medical conditions.

You don't say someone is a diabetes abuser or an asthma abuser, right?

You say they have a disorder.

That makes a lot of sense.

By changing the language, we actually lower the barrier to treatment.

If you feel judged, you don't go to the doctor.

If you feel you have a recognized medical condition, you might actually ask for help.

There's also a really clear distinction made early on between the disorder itself and the effects of the substance.

Substance use versus substance induced.

Yes.

Think of it this way.

Substance use disorder is the underlying engine.

That's the compulsion, the intense craving, the long term pattern of behavior.

Substance induced disorders are essentially the exhaust fumes.

The exhaust fumes.

I like that.

Right.

That's the intoxication, the acute withdrawal, the temporary psychosis or delirium that happens specifically because the drug is currently in your system or just leaving it.

So you have to treat both but differently.

Exactly.

You treat the induced symptoms immediately, like detoxing someone safely, but you have to treat the use disorder long term to prevent them from just coming back next week.

And the DSM -5 is widening the net on what constitutes a use disorder, isn't it?

It's not just about swallowing pills or drinking liquids anymore.

This part is fascinating.

Gambling disorder is now officially categorized alongside substance disorders in the DSM -5.

Just because it hits the brain the exact same way.

Precisely.

The functional MRI of a gambler winning a jackpot lights up the exact same dopamine pathways as a person taking a hit of cocaine.

The brain literally doesn't know the difference between a chemical high and a behavioral high.

Wow.

The text also mentions internet gaming disorder as a condition for further study, which really hints that we're going to see more of these behavioral addictions recognized in the future as the science catches up.

Let's talk about the scope of this.

Who are we actually treating in psychiatric nursing?

The short answer?

Absolutely everyone.

But the statistics in the text are sobering.

Alcohol is by far the most misused substance.

But looking at adolescents, kids aged 12 to 17, but one in 12 has a substance use disorder.

One in 12.

That's basically two or three kids in every single high school classroom.

Depending on the class size, yes, it's everywhere.

And on the flip side, the elderly population, people we might mistakenly assume are past this kind of risk.

They have a rapidly rising rate, up to 15 percent in some demographics.

But the number that really keeps psychiatric nurses up at night is the treatment gap.

The text said something like 90 percent, right?

Over 90 percent of people who actively need treatment for an SUD do not receive it.

That is just a staggering failure of the system.

Imagine if 90 percent of people with broken legs just didn't get casts.

It's a great analogy.

And the text notes that a huge reason for this gap isn't just a lack of hospital beds or insurance money, though that is certainly part of it.

It's that the people themselves do not perceive a need for treatment because they're in denial, because that is the cunning nature of the disease itself.

It literally rewires your brain to convince you that you are completely fine, that you have it under control.

That actually leads us perfectly into section two of our outline, which is comorbidity, because usually addiction isn't the only thing going on with a patient.

The text calls it a tangled web.

We call this the dual diagnosis concept in nursing.

The stats here are incredibly clear.

Fifty to 60 percent of people with a mental disorder also have a substance use disorder and vice versa, which always begs the question, which comes first?

Is it the severe depression leading to the drinking or the heavy drinking causing the depression?

It's the classic chicken and egg scenario, and it varies by patient.

The text offers a few theories for this connection.

A major one is self -medication.

If you have crippling social anxiety and you discover at age 16 that three shots of vodka makes that anxiety completely vanish,

well, you've just found a medicine that works.

Until it doesn't work anymore.

Right.

Until it destroys your liver and your life.

And genetics plays a role in this dual diagnosis, too.

A huge role.

There are shared genetic vulnerabilities.

The exact same neural wiring that might predispose you to mood instability or schizophrenia might also predispose you to substance dependence.

But as nurses, we have to be hyper vigilant about the ultimate risk here, which is suicide.

How strong is that link?

It's terrifyingly strong.

The risk of suicide is about 10 percent higher than the general population for substance users.

And for alcoholics specifically, it's actually 15 percent higher.

Why is it so much higher?

Is it just the compounding effect of the depression?

It's the combination of despair and disinhibition.

Suicide often requires a moment of extreme impulsivity and a temporary lack of fear.

The underlying depression gives you the despair, but the drugs or the alcohol give you the disinhibition.

They literally turn off the stop button in the frontal lobe.

It's a lethal cocktail.

Beyond the psychiatric comorbidity, the text goes into really intense detail about what these substances do to the physical body.

And I want to drill down on alcohol specifically.

We all know about the liver, cirrhosis is pretty common knowledge, but the brain damage, specifically, Wernicke -Korsakov syndrome.

I found this section really dense in the book.

Can we unpack this for the students?

Absolutely.

Because this is something every single nursing student sees on their board exams.

It's essentially a two part neurological tragedy caused by a severe thiamine deficiency.

That's vitamin B1.

Why thiamine specifically?

What does it do?

Think of thiamine as the spark plug for your brain cells.

It helps convert the fuel you eat into usable cellular energy.

Chronic alcohol misuse does a double whammy on this process.

First, it suppresses your appetite so you don't eat well and you aren't taking in thiamine.

Second, it physically damages the stomach lining and intestines so you can't even absorb the small amount of thiamine you do consume.

So your brain essentially starts starving for energy.

Exactly.

And that starvation leads to the first stage, which is Wernicke's encephalopathy.

This is an acute condition.

The patient comes into the ER profoundly confused.

Their eyes are doing weird things, which we call nystagmus, rapid twitching, or even paralysis of the ocular muscles.

And they have ataxia.

Meaning they are physically unsteady.

Right.

They are wobbly.

They walk like they are currently blackout drunk, but they're actually neurologically compromised from the vitamin deficiency.

And this acute stage, it's reversible.

It is.

But only if you catch it fast.

If a triage nurse recognizes those specific signs and says, we need a high dose thiamine injection stat, you can reverse the damage.

But if you miss it or misdiagnose it as just simple intoxication.

It becomes Korsakoff's.

Yes, it progresses into Korsakoff's psychosis.

And this stage is chronic and largely irreversible.

The hallmark here is profound memory loss.

They literally cannot form new memories.

But the fascinating and frankly sad symptom the text highlights is confabulation.

Confabulation.

That's making up stories, right?

Like lying to the nurse.

It looks exactly like lying, but clinically it's not.

The brain has these massive black holes in its memory timeline.

So it subconsciously invents a highly detailed story to fill the gap.

Just to make sense of things.

Right.

You ask the patient, where were you yesterday?

And they confidently say, oh, I was at the park with my sister having a picnic.

When in reality, they've been in the hospital bed for three weeks.

They truly believe the story.

They're just trying to make sense of a completely fragmented reality.

That is absolutely heartbreaking to witness, I imagine.

It is.

It really tests your empathy.

Moving to other drugs, the medical toll is just as devastating.

Stimulants like cocaine and methamphetamine, they are massive vasoconstrictors.

They clamp down hard on your blood vessels.

So the heart suddenly has to pump against a brick wall.

Exactly.

That leads to myocardial infarctions or heart attacks, strokes and severe malnutrition because they completely suppress the appetite center in the brain.

And for 5V drug users, the text really highlights the risk of endocarditis.

I've heard of this.

It's an infection of the heart valve, right?

Yes.

Bacteria from the unwashed skin or the dirty needle itself gets pushed directly into the bloodstream and colonizes the heart valves.

It grows into these bacterial clumps called vegetations, and pieces of these clumps can break off.

And the text mentions a very specific physical assessment sign for this.

Splinter hemorrhages.

That's the classic red flag.

You look closely at the patient's fingernails and you see these little vertical dark red or brown lines under the nail.

They look exactly like tiny wood splinters.

They're blood.

Right.

They're actually tiny blood clons microemboli that showered off the infected heart valve, traveled all the way down the arm and got stuck in the tiny capillaries of a nail bed.

If a nurse sees that during an assessment, it's a massive warning sign for IV drug use and a potentially fatal heart infection.

OK, let's go deeper into the brain.

Section three is neurobiology.

We talked about the hijacked brain earlier, but how does that actually work mechanically?

The text talks a lot about the reward pathway.

This pathway is the biological engine of the entire disorder.

The text breaks the brain down into three distinct parts for simplicity.

You have the brain stem, which handles basic survival, like breathing and heart rate.

You have the limbic system, which contains the reward circuit and the cerebral cortex, which is the thinking decision making brain.

And the limbic system is where the drugs do their work.

That's where the dopamine is.

Dopamine is essentially the do it again chemical.

When you eat a great meal, when you have sex or even when you just bond with a good friend,

your brain releases a little squirt of dopamine.

It feels good.

It tells the survival center of the brain, hey, this behavior is valuable for keeping us alive.

Remember this and do it again.

So what happens to that system when you introduce something like heroin or crystal meth?

It's no longer a little squirt.

It's a massive flood.

Some of these drugs release up to 10 times the amount of dopamine as any natural reward ever could.

It completely drowns the circuit.

So the primitive part of the brain actually thinks this chemical is 10 times more important to my survival than food or water.

Exactly.

It completely rewrites the biological survival hierarchy.

But here is the catch.

And the text calls this process neuro adaptation.

The brain is designed for homeostasis.

It hates being flooded out of balance.

So if you keep flooding it with synthetic dopamine,

the brain fights back.

It actually reduces the number of dopamine receptors available.

It turns down the volume knob to protect itself.

Precisely.

It literally pulls the receptors inside the cell wall.

So now you have fewer cups available to catch the rain.

This is the cellular basis of tolerance.

You need more and more of the drug just to get the same initial splash.

But what happens when the drug wears off or they try to quit?

That is the real tragedy of neuro adaptation.

Now, the patient has a normal everyday amount of natural dopamine flowing, say from eating a good meal or seeing a beautiful sunset.

But they hardly have any receptors left to catch it.

So they don't feel anything.

Right.

They enter a state of anedonia, which is the complete inability to feel pleasure.

At that point, they aren't using the drug to get high anymore.

They are using it just to feel baseline normal, just to get out of the dark hole they are trapped in.

The text also mentions glutamate in this section.

This is the memory part of the addiction, right?

Yes.

Glutamate is crucial for nurses to understand.

While dopamine says this feels incredibly good, glutamate says,

remember exactly where we are right now.

It locks in the memory of the environment,

the specific smell of the bar, the sight of a burnt spoon, the music playing a specific street corner.

So five years into recovery, you walk past that specific bar and your glutamate fires immediately.

It wakes up an intense craving.

It's a physical neurological reflex, not a sudden weakness of moral will.

The brain is reacting automatically to a survival cue it learned years ago.

We also really have to touch on genetics and trauma here because it's not just the drug itself.

It's the brain you were born with or the brain you developed as a child.

Genetics account for roughly 40 to 60 percent of a person's vulnerability to addiction.

But the text places a massive emphasis on environmental triggers, specifically ACEs,

adverse childhood experiences, things like physical abuse, neglect, growing up in a chaotic home.

Yes, there was a very specific and alarming statistic in the chapter about having four or more of these ACEs.

Right.

A child with four or more ACEs has a seven times higher risk of developing alcoholism later in life.

Seven times because trauma literally primes the developing brain.

It dysregulates the stress response system, the cortisol levels long before the kid ever takes their first drink.

They grow up already feeling physically and emotionally uncomfortable in their own skin.

So when they finally find the drug, it provides profound instant relief.

Let's shift gears to a very difficult clinical topic from section four.

Pregnancy and substance use.

The text is incredibly strict on this front.

It has to be.

The quote is there is no safe amount of alcohol to drink during pregnancy.

That is the hard rule.

Alcohol is a known teratogen, meaning it physically malforms the developing fetus.

Yes, it causes fetal alcohol syndrome or FAS.

And it's tragic because the damage is entirely permanent.

The text lists three main criteria for diagnosis,

mental retardation or cognitive deficits,

delayed physical growth and very specific facial abnormalities.

Like small eye openings and a thin upper lip.

Right.

It fundamentally wires the child's brain and body differently from the very beginning.

And what about opioids?

We hear so much in the news about babies being born addicted to painkillers or heroin.

The clinical term the text uses is neonatal abstinence syndrome or NAAS.

The baby isn't physically malformed in the face, like with alcohol, but they are born fully chemically dependent on the opioid.

And when the umbilical cord is cut, the supply stops.

Exactly.

The text vividly describes their primary symptom, which is a very specific high pitched cry.

A high pitched cry.

It's a distinctive continuous piercing sound.

It's the sound of an infant in severe neurological pain.

They have tremors.

They're hyper irritable.

They can't sleep.

They can't coordinate swallowing to eat properly.

They are going through cold turkey, heroin withdrawal at one day old.

And the text also briefly mentions nicotine during pregnancy.

Yes.

Nicotine is a potent vasoconstrictor.

It restricts blood flow through the placenta, which leads to low birth weight and a significantly higher risk of sudden infant death syndrome or SIDs.

Moving into section five, we have some key clinical concepts.

We need to clearly define some terminology here because these words dictate exactly how nurses assess and treat these patients.

We've covered tolerance.

We intuitively know intoxication.

But the text uses the term synergistic effects.

This sounds like an algebra problem.

It is math, but it's very scary clinical math.

Synergism is when one plus one equals five.

Give me a real world nursing example of that.

The classic example is mixing alcohol and benzodiazepines like Xanax or Valium.

Both of these are CNS depressants.

They both independently tell the central nervous system to slow down.

If you take them separately, you might just get very sleepy.

But together.

If you take them together, they don't just add their effects together linearly.

They potentiate each other exponentially.

They completely slam the brakes on the brainstem.

This is exactly how people stop breezing in their sleep and die from what they mistakenly thought was a moderate amount of pills and booze.

And the opposite of that reaction is antagonistic effects.

Right.

Think of it like a villain and a hero fighting for the same parking spot.

One drug actively blocks or reverses the other.

The absolute classic example here is naloxone or Narcan.

It chemically bullies the opioid off the brain's receptor site.

It takes its place, creating an immediate reversal of the overdose.

Exactly.

We'll talk more about how tricky Narcan can be in a minute.

There's one highly behavioral term in this section that stood out to me.

Codependency.

This is a huge concept for psychiatric nurses dealing with the families of patients.

The text describes codependency as dysfunctional helping dysfunctional like the wife calling the husband's boss on a Monday morning to say he has a terrible stomach flu and he's actually just severely hung over.

That is the textbook example.

She truly thinks she is helping him.

She believes she is saving his job and keeping the family afloat.

But clinically, she is enabling the disease.

She is artificially removing the natural painful consequence of his drinking behavior.

So he never hits rock bottom.

If he never feels the pain of losing the job, he never has an internal reason to seek change.

The nurse has a very delicate job here.

You have to identify this dynamic and gently help the family see that their love is actually prolonging the illness.

Okay.

Stick with me here because we are hitting section six.

This is the absolute meat of the chapter, the drug classes, the text breaks these down into very detailed tables and we need to walk through them step by step because this is exactly what a nurse is going to see on a Tuesday night in the ER.

Let's do it.

It's critical information.

First up on the table, CNS depressants.

So that's alcohol, benzodiazepines, and barbiturates.

Here is the golden bolded rule for nursing students.

Withdrawal from CNS depressants is a life threatening medical emergency.

It can and will kill the patient if unmanaged.

I think the general public gets really confused by this.

They think heroin withdrawal is the deadly one because it looks so dramatic and agonizing in the movies.

But alcohol is actually the dangerous one.

Yes, absolutely.

Think of the brain of a chronic alcoholic like a car.

You have the gas pedal floored, which is your body's nervous system desperately trying to stay awake and function.

But the brake pedal is also floored, which is the massive amount of alcohol keeping the brain sedated.

So the car stays relatively still.

Okay.

I'm with you on the analogy.

Now imagine you suddenly take your foot completely off the brake pedal, meaning you stop drinking cold turkey, but your body still has the gas pedal floored.

What happens to the car?

The car just violently shoots forward.

The brain shoots forward into hyperdrive.

That is alcohol withdrawal syndrome.

The central nervous system explodes with unopposed electrical activity.

There are pulse races, blood pressure spikes dangerously high, and anxiety goes through the roof.

And the tech says the timeline really matters for the nurses assessment here.

It does.

The mild symptoms start fast, usually within six to eight hours of the last drink.

That's the classic shakes or tremors.

But the real danger zone hits between 48 to 72 hours.

That's when you see delirium tremens or the DTs.

What does a patient in full blown DTs look like to the nurse walking into the room?

They are completely terrified.

They are acutely delirious and hallucinating.

Often these are tactile hallucinations, like feeling actual bugs crawling under their skin or visual ones.

They are sweating profusely with a high fever.

And most importantly, they are at an incredibly high risk for generalized tonic -clonic seizures.

And those seizures are what can be fatal.

Yes.

So as nurses, we need a standardized way to measure this risk before it happens.

The text emphasizes the CIWA scale.

CIWA, the Clinical Institute Withdrawal Assessment.

It's essentially a symptom scorecard.

The nurse regularly rates their nausea, their tremors, their sweating, their anxiety level.

If the total score hits a certain threshold, the nurse is authorized by protocol to administer medication immediately.

And what medication are we giving them?

Benzodiazepines, usually Ativan or Librium.

Wait, isn't a benzo just giving them another CNS depressant?

Exactly.

That's the point.

You are artificially, gently putting the brake pedal back down just a little bit.

So you can ease it off slowly over several days rather than letting the car crash into the wall.

It physically prevents the brain from seizing.

Okay.

So once they are safely through detox and sober, there are maintenance meds to help them stay that way.

The text lists three big ones.

Desulfurum, which most people know as Antibuse is probably the most famous.

Antibuse is a classic form of aversion therapy.

It alters the way the liver metabolizes alcohol.

So if you take your pill and then you drink alcohol, you get a massive buildup of a toxic by -product called acetaldehyde in your blood.

It causes violent vomiting, a pounding headache, severe flushing, and palpitations.

It literally feels like you are dying.

So it's a severe chemical deterrent.

It's a biological booby trap.

But the critical nursing intervention here is patient education.

You have to teach the patient that it's not just drinking a beer that sets it off.

If you vigorously swish with an alcohol -based mouthwash or eat a salad with heavy wine vinegar, or even apply a strong alcohol -based aftershave to your skin boom, you trigger the violent physical reaction.

That requires so much caution.

Then there is Naltrexone and Acamprosy.

How are they different?

Naltrexone works on the reward pathway.

It actually blocks the euphoric high.

So if a patient slips up and takes a drink, they won't get that warm, fuzzy rush of dopamine.

It chemically uncouples the behavior from the reward.

Acamprosate or Campral is different.

It helps with the brain ache.

The brain ache.

Yeah.

The persistent dysphoria, the breathlessness, and the low -level anxiety that comes with early sobriety.

It helps normalize the disrupted brain chemistry.

So the patient feels emotionally okay enough to actually stay sober.

Let's move to the next major class, opioids,

heroin, fentanyl, oxycodone.

The defining public health epidemic of our time.

Assessment is absolutely key here for survival.

What exactly is the opioid overdose triad?

If a nose finds someone unresponsive, you immediately look for three specific things.

One, coma, meaning they are unarousable.

Two, respiratory depression, meaning the breathing is incredibly slow, shallow, or has stopped entirely.

And three, pinpoint pupils.

Pinpoint.

Yes.

The black center of the eye shrinks down to the size of the head of a pin.

If you see those three signs together, you assume an opioid overdose and you immediately get the Narcan.

Talk to me about Narcan or Naloxone.

The text has a very specific bolded warning for nurses about the drug's half -life.

This is a life -saving clinical detail.

Narcan works incredibly fast.

It kicks the heroin off the receptor and the patient wakes up.

Usually gasping for air.

But, and this is a massive Narcan, but Narcan has a much shorter half -life than most of the opioids it's reversing.

Narcan wears off in about 30 to 90 minutes.

And the heroin or fentanyl?

Heroin can last in the system for four to six hours.

Methadone lasts for 24 hours or more.

So the Narcan wears off, but the lethal dose of the opioid is still circulating in their bloodstream.

Exactly.

And the patient silently slips right back into the coma and stops breathing again while lying in the ER bed.

Nurses absolutely have to know this.

You cannot just hit them with Narcan, see them wake up and send them out the door.

You have to continuously monitor them and readministration is very often required.

And when they first wake up from the Narcan?

Oh, they are usually not happy.

You have just forced them into immediate precipitous withdrawal.

All their pain receptors turn back on at once.

They are in agony.

They are vomiting.

They are highly agitated.

It can be a very volatile and dangerous scene for the nurse.

What about natural withdrawal from opioids?

Is it fatal?

Like alcohol?

It absolutely feels fatal to the patient, but medically it's not.

The text describes it as severe flu -like symptoms, deep bone and muscle aches, high fever, constantly runny nose, diarrhea, severe yawning and goose flesh, which is actually where the term cold turkey comes from.

It is utterly miserable.

But unlike alcohol, it rarely causes fatal seizures.

We assess the severity of this with the CIWS scale, right?

Yes, the clinical opiate withdrawal scale.

It's very similar in concept to the CIWA score, but tailored for opioid symptoms.

It dictates how we dose medications to ease their profound discomfort.

And for long -term recovery, we have MAT, medication assisted treatment, the text lists methadone and buprenorphine.

Methadone is a full opioid agonist.

It binds to the receptors and replaces the heroin, but it has a very long, stable action.

So there's no dramatic high and no crashing low.

They just feel normal.

Suboxone is another major one.

It's a combination drug, buprenorphine plus naloxone.

Why combine them?

Why add the naloxone if it blocks opioids?

It's a brilliant chemical designed to prevent abuse.

If the patient takes the suboxone film and dissolves it under their tongue, exactly like they're supposed to, then naloxone is completely inert.

It does nothing.

So they try to abuse it.

If they try to melt it down and inject it into a vein to get a rush, the naloxone immediately activates in the bloodstream and blocks the opioid effect, throwing them into instant withdrawal.

It's a built -in pharmacological safety mechanism.

Let's look at the next class, CNS stimulants, cocaine, crack,

methamphetamine.

The physical presentation is the total opposite of the depressants.

The patient is completely revved up.

Their pupils are dilated, meaning huge, not pinpoint.

Severe tachycardia, extreme paranoia and hypervigilance.

The text mentions the physical toll of methamphetamine is exceptionally graphic.

Yes.

Meth mouth is a classic sign.

The drug causes severe dry mouth and intense vasoconstriction in the gum tissue.

The teeth literally rot at the root and fall out.

And the skin users often experience formication, which is the delusion that bugs are crawling under their skin.

So they pick at themselves constantly.

You see deep open sores and secondary skin infections all over the face and arms.

But the real silent killer here is the cardiovascular system.

Absolutely.

If a 25 year old patient comes into triage complaining of crushing chest pain, the nurse must assume cocaine use until proven otherwise.

It causes massive coronary artery spasms.

They can have a lethal myocardial infarction despite having zero plaque in their arteries.

What about stimulant withdrawal?

The text simply calls it the crash.

It's psychological torture rather than physical danger.

When the binge ends, they might sleep for three days straight and they eat everything in sight.

But the depression they wake up to is profound.

The suicide risk during a severe stimulant crash is extremely high because their brain is completely utterly defeated of dopamine.

There is no medication you can give them to magically fix it.

Nursing care is entirely supportive.

Sleep, heavy nutrition, and a strict suicide watch.

Lastly, for the drugs, Section 6 covers club drugs, hallucinogens, and inhalants.

Ecstasy, or MDMA, creates this intense artificial sense of empathy and connection, but it scrambles the body's temperature regulation.

Patients come in with severe hyperthermia, literally cooking their own organs, and they are at risk for serotonin syndrome.

And then you have the date rape drugs, Rohypnol and GHB.

The text explicitly notes these cause anterograde amnesia.

Which means the brain loses the ability to form new memories after the drug is adjusted.

You wake up the next morning and have absolutely zero idea what happened to you or who you were with.

The text mentions a safety feature in newer formulations of Rohypnol.

The pill actually turns blue if it's dissolved in a liquid.

But obviously you can't rely on that in a dark club.

Exactly.

And finally, inhalants.

Huffing paint, glue, or aerosols.

The text uses a terrifying phrase for this, sudden sniffing death.

That is the actual medical terminology.

The inhaled chemicals can sensitize the heart muscle so severely that a sudden startle, like a parent walking into the room, causes a massive adrenaline rush that throws the heart into fatal cardiac arrest.

Happens very fast.

And tragically, it is most common in young adolescents.

OK, we've covered the pathology and the drugs.

Now section seven, the nursing process.

How do we actually assess and uncover if a patient is struggling with these issues?

It all starts with screening.

The text heavily features the cage questionnaire.

It's beautifully simple.

Just four questions.

C -A -G -E.

Walk us through the acronym.

C,

have you ever felt you ought to get down on your drinking or drug use?

Have people annoyed you by criticizing your drinking?

Have you ever felt bad or guilty about your drinking?

Have you ever had an eye opener, meaning a drink first thing in the morning to steady your nerves or get rid of a hangover?

And how is it scored?

If the patient answers yes to just two of those four questions, it's a positive screen.

It tells the nurse we need to dig much deeper here.

The text also mentions the BDAST for drug abuse screening.

But asking these questions directly is incredibly hard.

Patients lie.

They get defensive.

They deny there's an issue.

They absolutely do.

But the text gives specific communication advice on this.

The nurse cannot take it personally.

You have to understand that denial is a powerful psychological defense mechanism against deep shame.

The nurse needs to act like an investigative detective, not a moral judge.

You lean heavily on objective data.

Give me a clinical example of how a nurse should phrase that.

Instead of walking in and saying, I think you're an alcoholic, which immediately starts a defensive fight.

You say, I noticed your hands are trembling this morning and your lab work shows significantly elevated liver enzymes.

In my experience, these things often happen with heavy alcohol use.

Can you tell me a bit about your drinking habits?

It's really hard to argue with a physical tremor and a lab value.

Exactly.

You present the facts neutrally.

But before the nurse even walks into that room, the text mandates a crucial step.

Self -assessment.

Examining your own bias.

This is non -negotiable.

Nurses are human beings.

Maybe you grew up with an abusive alcoholic father.

Maybe your religious background dictates that drug addiction is a profound moral sin.

If you walk into that patient's room carrying that unexamined bias, the patient will instantly feel your judgment.

And they will completely shut down.

They will.

You have to rigorously examine your own feelings and triggers so you can provide neutral, evidence -based, compassionate care.

You have to view their inevitable relapses as a symptom of the chronic disease, not as a personal failure or a waste of your nursing time.

That concept leads directly into what might be the most uncomfortable section of the whole chapter.

Section 8,

the impaired professional.

It is the giant elephant in the break room.

The statistics in the text blew my mind.

Nurses have the exact same addiction rates as the general public.

Yes, roughly 10 to 15 percent.

But you have to think about the unique occupational context.

Nurses deal with incredibly high emotional stress,

severe physical pain from back and joint injuries, and most importantly, they hold the literal keys to the narcotic cabinet.

Access is a massive risk factor.

So what are the warning signs?

If I'm a floor nurse,

what behavioral changes am I looking for in my coworker?

You are looking for subtle but consistent patterns.

Are they constantly volunteering to give your pain meds for you?

Like, oh, you look busy.

I'll go ahead and medicate your patient in room three for you.

Are they working a lot of extra overtime shifts, specifically night shifts or weekends when management supervision is low?

Are they taking very frequent long bathroom breaks?

What about patient interactions?

That's the biggest red flag.

If a patient complains to you saying that pain shot my other nurse gave me an hour ago didn't help at all, I'm still in agony.

But you look at the chart and it says they received two milligrams of IV deloaded.

Well, maybe the patient didn't actually get it.

Maybe the nurse diverted the medication into their own pocket.

Exactly.

So what do you do?

The text talks extensively about the ethical dilemma here.

It's this agonizing poll between loyalty to your friend and colleague versus safety.

It absolutely feels like a horrible betrayal to report a coworker.

You know they could lose their license.

But the text is completely firm on this, citing the ANA code of ethics.

Your primary overriding duty is to the safety of the patient.

An impaired nurse is a highly dangerous nurse.

They make lethal medication errors.

You must report your suspicions to a nurse manager or supervisor.

But the text also offers a surprisingly hopeful perspective on what happens next.

It's not necessarily an automatic career death sentence.

No, the culture is slowly changing.

We have alternative to discipline or ADT programs now.

The primary goal of the Board of Nursing in these programs is intensive treatment and rehabilitation, not just punitive firing.

If the nurse fully complies with the strict rehab program and random drug monitoring, they can eventually return to safe practice.

The philosophy is we want to save the nurse's life and career, not just discard them.

That brings us to Section 9, implementation and therapeutic modalities.

What do we actually do with these patients on a daily basis?

The text shares a really compelling vignette about a patient named Kristin.

She's a chronic heroin user.

She's lost custody of her kids and she is incredibly angry and defensive on the unit.

Yes, the student nurse in that story feels very intimidated by her.

Kristin is yelling and pacing.

But the clinical lesson the authors are teaching is the delicate balance of setting limits while simultaneously validating feelings.

How does a nurse practically do both of those things in a heated moment?

The nurse says something like, Kristin, it is frightening to see you so angry right now, and I truly want to hear what is upsetting you, but I cannot talk to you while you are screaming and pacing.

You explicitly validate the underlying emotion, which is anger and fear.

But you set a firm, safe boundary on the outward behavior, which is the screaming.

The text also heavily highlights the technique of motivational interviewing in this section.

This is a core psychiatric nursing skill.

The absolute key phrase here is rolling with resistance.

If the patient aggressively says, I don't have a drinking problem, I can quit any time, you do not argue back and say, yes, you do look at your little labs.

That just entrenches their denial.

So what do you say instead?

You roll with it.

You say, OK, so you feel like your alcohol use is completely under your control.

Tell me, how does getting a DUI last week fit in with your long term goal of getting your commercial driver's license back?

Wow.

You let them find the massive hole in their own logic.

Yeah, exactly.

It's called developing the discrepancy.

It is a hundred times more powerful if the patient articulates the contradiction themselves rather than the nurse lecturing them about it.

And as we move toward discharge planning, the text outlines relapse prevention.

There's an acronym here that I think is useful for everyone, not just addicts.

Yes, the HALT acronym, HALT.

Walk us through what it stands for.

These are the four most common physiological and emotional triggers for a relapse.

You teach the patient,

never let yourself get too hungry, too angry, too lonely or too tired.

When you hit those extreme states, your frontal lobe weakens, your coping mechanisms fail, and the craving takes over.

The text also mentions a phenomenon called PAWS, post -acute withdrawal syndrome.

This is crucial education.

Long after the physical detox is over, the brain is still struggling to heal its receptors.

For up to two years, the patient might experience sudden severe mood swings, deep depression or intense insomnia.

If nobody tells them this is normal brain healing, they will think they're going crazy and just relapse to fix it.

Lastly, the chapter covers different recovery models because it's definitely not a one size fits all disease.

Not at all.

You have the traditional 12 -step programs like AA or NA.

These are highly structured, fellowship based, and inherently spiritual.

They emphasize surrendering to a higher power and admitting total powerlessness over the drug.

But that doesn't resonate with everyone.

Right.

So we also have SMART recovery, which is completely cognitive based.

It relies on self -reliance, behavioral therapy techniques, and changing your thought patterns rather than spirituality.

And then fundamentally different from both, you have the harm reduction model.

Harm reduction.

The text gives examples like clean needle exchange programs and wide distribution of Narcan to active users.

Yes.

The philosophy of harm reduction is radically pragmatic.

It says, okay, you are not ready or willing to completely stop using heroin today, we accept that, but let's at least make sure you use a clean needle so you don't contract HIV and let's make sure you have Narcan in your pocket so you don't die of an overdose tonight.

It essentially keeps the patient physically alive until the day they finally are ready to choose recovery.

Wow.

We have covered just an incredible amount of ground today, all the way from the holistic spirit body connection down to the liver enzymes, from the massive dopamine flood and the limbic system to the heartbreaking high -pitched cry of a newborn with NAS.

It is a massive, incredibly heavy topic, but if nursing students or just everyday listeners take only one thing away from this deep dive into chapter 19, I really hope it's the clinical concept we started with.

The hijacked brain.

The rights.

This isn't a fundamentally bad person making malicious choices.

It is a profoundly broken brain circuit, desperately driving a primitive survival behavior.

And for the future nurses out there listening,

rigorous self -assessment to check your bias,

hypervigilance for the clinical signs in your patients and your colleagues, and absolutely never, ever underestimate the lethal danger of acute alcohol withdrawal on your unit.

Absolutely.

Those are the clinical lifesavers.

There is a truly provocative thought tucked right at the end of the text regarding the impaired professional section.

I want to leave the listener with it.

It asks you to genuinely visualize the scenario.

If it was your favorite mentor, the senior nurse who trained you, who supported you, who you love, and you saw the subtle signs of diversion,

would you actually make the call to the supervisor?

It is the hardest professional call you will ever have to make.

But as the text reminds us, it might be the only thing that saves their life and the lives of their patients.

Such a powerful reality check.

On that note, we want to say a huge warm thank you from the entire last minute lecture team for joining us and helping us navigate this dense,

difficult, but incredibly vital material.

Keep studying hard, trust your assessments and keep your compassion batteries fully charged.

We will see you on the next deep dive.
