Chapter 26: Bipolar Disorders in Mental Health Care

Welcome to Last Minute Lecture.

This free chapter overview is designed to help students review and understand key concepts.

Welcome back to The Deep Dive.

We have a massive stack of research on the desk today, and honestly, the topic we're covering is one of the most, well, one of the most paradoxical conditions in all of medicine.

It really is.

We are opening up the textbooks, specifically chapter 26 of Psychiatric Nursing, the seventh edition, to break down bipolar disorders.

And we aren't just skimming the surface here.

No, you can't with this topic.

We are going to decode the symptoms.

We're going to look at the biological theories, which are surprisingly complex.

And most importantly, for those of you looking to apply this in a clinical setting, we're going to look at the nursing interventions required to manage these patients.

Paradoxical is absolutely the right word for it.

It is a disorder that can destroy a life while simultaneously making the person feel like a god.

Right.

It's a heavy topic, but it's an essential one.

You know, when we talk about mental health, we often use words like depression or anxiety, sort of colloquially.

But bipolar disorder is a different beast entirely.

It represents the extreme poles of human experience.

That is exactly where I want to start to really get a handle on why this disorder is so difficult to treat and frankly, so confusing for families.

I want to start with a quote found right in the text.

It's from M.

Orem.

Listen to this.

Nothing is more addictive than the high of a manic euphoria.

Wow.

That's a powerful opening.

It immediately reframes how we think about addiction, doesn't it?

It really does.

Usually we think of addiction in terms of external substances, you know, heroin, alcohol, gambling.

But here, the addiction is to the brain's own chemistry.

The drug is you.

And it goes on to describe the sensation in this incredibly vivid language.

Orem writes, once you have tasted that soaring, exhilarating, invincible, phantasmagorical feeling of, it's great to be me.

I can do anything.

Phantasmagorical.

That's a perfect word.

It is.

The quote continues.

Once you've experienced the rush of your mind and overdrive, then life without another mania is a dreary prospect indeed.

And that just captures it, doesn't it?

It implies something dreamlike, shifting, brilliant, almost magical.

The quote highlights the core conflict we see in treatment every single day.

Well, we as clinicians look at mania and we see destruction.

We see ruined finances,

ruined relationships, physical exhaustion.

We see a crisis.

But the patient.

The patient feels infinite.

They feel creative.

They feel like they've tapped into some hidden potential and asking them to give that up for a normal baseline.

I mean, it can feel like asking them to give up a superpower.

It's a really tough sell.

That's the hook, isn't it?

The seduction of mania.

But before we get too deep into the tragedy of the inevitable crash, let's get our definition straight.

What exactly are we dealing with here?

Okay.

So at its most basic level, bipolar disorders are a group of disorders involving extremes of mood polarity.

The two poles.

The two poles.

Yeah.

We're talking about swinging between euphoria, that phantasmagorical high and depression, which is, you know, the lowest low imaginable.

But here is the first key diagnostic rule that often trips people up.

Even students.

Okay.

To be diagnosed with bipolar E, which is kind of the classic, most severe form, a depressive episode, is actually not required for the diagnosis.

Wait, really?

I always assumed it was the swing back and forth that defined it.

I thought bipolar literally meant two poles.

Linguistically, yes, you're right.

And clinically,

let's be clear, almost everyone with bipolar eye will eventually crash into a severe depression.

It's part of the cycle.

But not for the diagnosis itself.

But strictly speaking, for the DSM -5 diagnostic criteria, you only need one manic episode.

Just one.

The depression is very likely to follow, but the mania is the defining feature.

If you've had that one week of true undeniable mania, you have bipolar eye disorder, regardless of whether you've been depressed yet or not.

Okay.

That's a crucial distinction.

It really changes how you think about it.

So let's talk about the scope of this.

Who is this affecting?

Because this isn't some rare anomaly.

Oh, not at all.

It's a massive public health issue.

In fact, the Centers for Disease Control has deemed it the most expensive mental health disorder in the United States.

More than major depression, more than generalized anxiety or schizophrenia, why is it so expensive?

It really comes down to a combination of direct and indirect costs.

We're looking at about 5 .7 million Americans affected yearly, which is roughly 1 .8 % of the adult population.

So it's common.

And the expense comes from?

The disruption, the sheer life disruption.

It causes immense loss productivity at work, frequent and often lengthy hospitalizations, and sometimes long -term care needs.

And importantly, it tends to hit people right in their prime.

When does it usually start?

What's the age of onset?

The median age of onset is 25 years old.

Wow.

So just as people are finishing college, starting careers, maybe thinking about starting families, boom,

the disorder emerges and creates this seismic shift in their entire life trajectory.

And interestingly, the text mentions that while bipolar eye affects men and women in equal numbers, the way it starts, the initial presentation often differs.

Yes, that's another really critical point for diagnosis.

Men tend to start their journey with manic episode.

They hit the ceiling first, so to speak.

So it's often more obvious, more dramatic.

It can be, yes.

Women, on the other hand, tend to start with a depressive episode.

That seems like it would make diagnosis incredibly tricky for women, at least initially.

It makes it a diagnostic minefield.

Think about it.

If a 25 -year -old woman comes into a clinic with severe depression and she has no history of mania yet, she is very likely to be diagnosed with major depressive disorder.

And then treated for that.

Exactly.

She might be put on antidepressants.

And as we will discuss later, giving an antidepressant to a person with an underlying bipolar brain is like throwing gasoline on a fire.

It can trigger the mania.

It can absolutely trigger that first manic episode.

It can flip them into mania or even induce rapid cycling.

So a misdiagnosis has very serious consequences.

That is a huge insight.

So our mission today is to really guide nursing students or anyone interested in the clinical side of this through this chapter.

We need to understand what this looks like in the real world.

So let's move into section one, the clinical picture.

We keep saying mania, but what does a manic episode actually look like according to the DSM -5?

Right.

Let's get specific.

So a manic episode isn't just being happy or having a really good day.

The DSM defines it as a distinct period of abnormally and persistently elevated, expansive, or irritable mood.

And there's a time component.

A critical time component.

It has to last at least one week, a full seven days of this persistent change.

Unless, there's always an unless.

Unless the symptoms are so severe that hospitalization is necessary.

If you land in the hospital because you're a danger to yourself or others after just two or three days, the duration doesn't matter.

It's a manic episode.

The severity trumps the duration.

Okay.

So one week of elevated mood, but surely there are more specific symptoms than just that.

Oh yes.

The textbook lays them out clearly.

We call this the three or more rule.

During this period of mood disturbance, you need three or more of the specific symptoms listed in the DSM -5 to be present to a significant degree.

And there's a nuance there, right?

There is.

If the mood is just irritable and not elevated or expansive, you actually need four of the symptoms.

Let's run through them because this is what a nurse is actually going to be seeing on the floor.

First up, inflated self -esteem or grandiosity.

This is one of the most common and defining features.

And we really need to distinguish this from healthy confidence.

You know, if you just got a promotion and you feel like you're on top of the world, that's normal.

Right.

Grandiosity in media is delusional in nature.

This is believing you have special powers or that you've figured out the cure for cancer overnight or that the president is personally waiting for your advice on foreign policy.

The text mentions a patient thinking they could just pick up the phone and call the White House.

Exactly.

It's a fundamental break from reality.

They simply don't see the barriers or limitations that exist for the rest of us.

In their mind, it's completely plausible.

Okay.

Next on the list is decreased need for sleep.

This is a huge one for nurses to watch.

It's a major red flag.

And notice the precise phrasing, decreased need.

We are not talking about insomnia where you're tossing and turning and you want to sleep but can't.

This is feeling fully rested, refreshed and energetic after maybe three hours of sleep or even none at all for a couple of days.

They just don't need it.

They have what seems like infinite energy on almost zero fuel.

That sounds exhausting just thinking about it.

Then there's the speech.

The text says pressure to keep talking.

We call this pressured speech and it's exactly what it sounds like.

Imagine a fire hose of words.

They are more talkative than usual.

It's rapid fire.

It's often loud and it's incredibly difficult to interrupt.

So they're not really having a conversation with you.

Not at all.

They aren't just talking to you.

They are talking at you and the words are just spilling out sometimes faster than their mouth can even form them.

There's an urgency to it that's palpable.

And what about their thoughts?

What's happening inside their head?

The thoughts are racing.

The term for it is flight of ideas.

Inside their head it's like a browser with a thousand tabs open and they're clicking through them at light speed.

So they jump from topic to topic.

Constantly.

They might see a bird outside the window and suddenly switch from talking about their breakfast to talking about aerodynamics, then to travel, then to the geography of Europe, then to a song they heard.

It's all that it's impossible to follow.

And I imagine that makes them very distractible.

Highly distractible.

That's the next criterion.

Their attention is drawn to any and every unimportant, irrelevant external stimulus.

You might be trying to do a vital science assessment and they're focused on the pattern of your tie or a noise down the hallway or a light flickering.

Their attention filter is just gone.

It's completely broken.

Every stimulus gets equal priority which means nothing gets focused attention.

And what about activity levels?

A marked increase in goal -directed activity.

This could be socially, at work, or sexually.

They might start a dozen projects at once and finish none of them.

Or it could be what we call psychomotor agitation.

Just purposeless movement, pacing back and forth, wringing their hands, can't sit still.

The engine is just redlining constantly.

And finally, the one that often causes the most damage.

Yes.

Excessive involvement in activities that have a high potential for painful consequences.

High risk activities.

Exactly.

Buying sprees, sexual indiscretions, foolish business investments.

This is where the life -wrecking consequences often come in.

Their judgment is severely impaired.

Their risk assessment center in the brain is completely offline.

They truly believe nothing can go wrong.

The text gives a really vivid and tragic example of this.

There's a case study about a man named Bill.

Yes.

Bill, the software CEO, this is a classic textbook example of both the power and the peril of this illness.

This story really stuck with me.

So, Bill built a multi -million dollar company from scratch.

An incredible achievement.

Then he bankrupted it.

Right.

Then he got up and built a second multi -million dollar company.

And he bankrupted that one too.

And that is the absolute tragedy of this success of mania.

Bill explicitly credits the illness for his business acumen.

He says the energy, the creativity,

the drive at all helped him build those empires.

So the hypomanic phase was his superpower.

In a way, yes.

That phase gave him the ability to work 20 hours a day, to be charismatic, to sell his vision to anyone.

But the full -blown mania, the grandiose thinking, the belief that the government couldn't possibly function without his software, the unrealistic expansion plans, that's what destroyed them both times.

And it wasn't just the businesses.

He's very candid that he lost two wives and three children along the way.

Exactly.

The human toll is immense.

The text says he lives in a county -operated apartment now.

He volunteers at a mental health center.

He's stable on his medication, but he admits he'll never be a wheeler -dealer again.

He tells that story about the Cadillac dealership.

Right.

Driving into a Cadillac dealership and buying two brand new cars.

One for him, one for a girlfriend he'd just met.

He didn't have the money.

He put it on credit cards.

But in that moment,

consequences just didn't exist.

It's a perfect snapshot of manic impulsivity.

It's just heartbreaking because the very thing that made him feel so exceptional was the same thing that dismantled his entire life.

Now, that's full -blown mania, but the text also talks about hypomania.

How's that different?

Think of hypomania as mania light.

But that nickname can be a bit deceptive because it implies it's not serious, which isn't true.

The main clinical differences are duration and severity.

Okay, so duration first.

A hypomanic episode lasts at least four consecutive days, whereas mania, as we said, is a full week.

Four days versus seven days.

Got it.

And this severity.

It's not severe enough to cause marked impairment in social or occupational functioning or to necessitate hospitalization.

In fact, to the person experiencing it, they often feel great.

They feel productive, sharp, witty, creative.

So it doesn't look like a crisis.

Not usually.

It's often observed by others, by friends or family, as a noticeable change in their typical behavior.

They're more talkative, more energetic, but it doesn't scream emergency.

The text mentioned there's a debate about this, specifically from an expert named Wilf.

Right.

Wilf argues, and I think it's a valid point, that the four -day threshold might be too arbitrary.

What if someone is showing all these symptoms, clearly escalating, for two or three days?

Are they not heading for trouble?

So we might be missing people.

We might be missing a crucial window to intervene.

He suggests we might be missing people who need help because they don't meet that strict time criteria yet.

Catching it early could prevent the full -blown episode or the subsequent crash.

That makes a lot of sense.

Now, we've talked about the high, the up -pull.

We have to talk about the low, the depressive episode, and bipolar disorder.

Is it the same as what we call regular or unipolar depression?

It's actually quite different, and this is another critical piece for diagnosis.

Bipolar depression often causes more subjective suffering for the patient than the manic state does, but the symptoms tend to be what we call atypical.

Atypical how?

What does that look like?

Well, in unipolar or regular depression, we often see classic symptoms like insomnia, the inability to sleep, and anorexia, a loss of appetite.

Right.

And bipolar depression, we often see the exact opposite.

We see hypersomnia sleeping way too much, maybe 14, 16, even 18 hours a day.

And we see hyperphagia eating too much, intense cravings for carbohydrates, and subsequent weight gain.

So they are essentially hibernating.

That's a great way to put it.

They're hibernating from the world.

And there's a very distinct physical sensation that's often described called leaden paralysis.

Leaden paralysis.

The patient feels physically heavy, like their limbs are made of lead.

They describe having to fight against immense gravity just to move, to get out of bed.

It's a profound physical inertia.

They're also much more likely to have paranoid thoughts, anxiety, and irritability compared to someone with unipolar depression.

Okay, so if you're a nurse and you see a patient who is sleeping 18 hours a day, eating constantly, gaining weight, and complaining that they feel like they can't physically move their arms, you should be thinking bipolar depression as a possibility.

Precisely.

That clinical picture should set off alarm bells for bipolar disorder.

So we have these building blocks.

Mania, hypomania, and this specific type of depression.

Now let's look at how they combine to form the specific disorders in section two.

The text lays out bipolar first, bipolar two, and cyclothymic disorder.

Let's start with bipolar one.

Okay, so bipolar eye disorder, BDI, is the most significant and severe form.

It's characterized by swings between full -blown manic episodes and typically major depressive episodes.

And the key, as you said before, is that single manic episode.

That is the one requirement.

If you have ever in your life had one manic episode, that full week of hospitalization level intensity with psychosis or severe impairment, you are diagnosed with bipolar one, period.

Even if you've only had one and the rest of your life has been depression.

Even then, that one episode redefines the entire course of the illness.

Got it.

So how is bipolar two different?

Bipolar two disorder, BD2, is characterized by swings between hypomanic episodes, that's the mania light we talked about, and major depressive episodes.

The key distinction here is that the person has never experienced a full manic episode.

So the up never reaches that same level of severity.

Exactly.

It never involves psychosis and it never gets so bad that requires hospitalization.

The highs are less high.

But the depression in bipolar two can still be just as severe as in bipolar one.

Oh, absolutely.

The depression is major depression.

It can be incredibly debilitating, life -threatening even.

It's just the up pole that doesn't reach the same extreme.

But there is a risk we need to mention.

Which is?

About five to 15 % of bipolar seven patients will eventually go on to develop a full manic episode.

And the moment they do, their diagnosis changes.

They transition to bipolar one.

There's a critical thinking moment in the text that I love.

It brings this into the real world.

It suggests that many workaholic executives or highly successful entrepreneurs might actually be living with undiagnosed hypomania.

It's a very valid and interesting theory.

Think about it.

The symptoms of hypomania, increased goal -directed activity, decreased need for sleep, inflated self -esteem, more talkative, more creative.

In a corporate or startup setting, those traits are often highly rewarded.

We call it drive or ambition.

Exactly.

We might look at a CEO who works 20 hours a day, flies across the country for meetings on no sleep, and is incredibly charismatic and persuasive.

And we say, wow, what drive, when in reality, we might be looking at a prolonged hypomanic episode.

It really blurs the line between personality and pathology.

It's a fascinating thought.

And then we have one more category in this section,

cyclophemic disorder.

The pendulum analogy from the text works best here.

Imagine a pendulum that swings back and forth but never quite reaches the top of the arc on either side.

So it's always in motion, but never at the extremes.

Precisely.

Psychothemia is when a person has symptoms for at least two years.

And during that time, they have numerous periods with hypomanic symptoms and numerous periods with depressive symptoms or dysthymia, which is a kind of minor chronic depression.

So they never meet the full criteria for a hypomanic episode, and they never meet the full criteria for a major depressive episode.

Exactly.

They're in this constant two -year -long flux of sort of up and sort of down.

It never quite stabilizes at baseline, but it also never explodes into a full episode.

That sounds incredibly draining.

It is.

And the risk here is that, according to the text,

15 to 50 percent of people with cyclothemia will go on to develop full -blown bipolar or bipolar 2 disorder.

It can be a precursor.

All right.

Let's put on our nursing scrubs.

Section three is nursing assessment.

We are walking onto the unit.

What does mania actually look like when you are standing in front of it?

What do you see and hear?

It is unmistakable.

It's an experience you don't forget.

Let's start with objective behaviors, what the nurse sees and hears.

First, the speech patterns we mentioned.

You will absolutely hear that pressured speech.

It's loud.

It's a rapid fire.

It feels like you're being pelted with words.

And the text mentions the singing patient.

All very common.

Manic patients often burst into song or they'll use constant rhyming and puns.

They might speak in riddles or clang associations.

They treat language as a toy, a playground.

It's that flight of ideas manifesting verbally, that brain moving too fast.

Now, the text lists manipulation as a major issue in social and interpersonal relationships.

It references a classic list from a researcher named Janoski.

Yes, and understanding this is absolutely crucial for staff survival on an inpatient unit.

Janoski identified these classic manipulative tendencies that you see again and again.

What's the first one?

First, they are adept at manipulating the self -esteem of others.

A patient might come up to you and say,

you are the only nurse here who really understands me.

The others are all idiots.

That's flattering, but dangerous.

It's a total trap because what they're doing is called splitting.

They find the vulnerabilities in the staff and they pit staff members against each other.

If you say no to a request, they'll go to the next nurse and say, well, the other nurse said it was okay.

It creates chaos and dissent among the team.

And what about limit testing?

Constantly, relentlessly.

They will push every single rule and boundary.

If curfew is at 10 p .m., they'll ask to stay up until 10 p .m.

If you let them tomorrow, they will push for 10 .30.

If you give an inch, they'll take a mile.

And it's not because they're bad people.

It's because their impulse control is gone.

The part of their brain that says stop is offline.

And this behavior inevitably leads to alienation, right?

The text mentions families often retreat.

It's one of the most tragic parts of the illness.

Families often retreat not out of cruelty or lack of love, but out of sheer bone -deep exhaustion.

They have dealt with the erratic spending, the verbal anger, the manipulation for years, sometimes decades.

They're burned out.

And strangers get scared off?

Absolutely.

A manic patient can be incredibly intrusive.

They might corner a stranger in a grocery store and start an overbearing rapid -fire conversation that is actually quite frightening to the other person.

They have no concept of personal space or social cues.

Let's talk about their appearance.

What are we looking for visually on the unit?

It's often loud, very loud, bright, garish colors, excessive, poorly applied makeup, layering clothes that don't make any sense, like wearing multiple coats in the summer.

Or you can see the complete opposite.

Total sloppiness.

Yes.

They might be so busy with their projects and racing thoughts that they don't bathe for days.

They might have poor hygiene, stained clothes,

and hyperactivity, the constant pacing, the flamboyant gestures.

That's a hallmark.

And subjectively, what are they telling you they feel?

Euphoria.

I feel great.

I've never felt better in my life.

But,

and this is a huge brat, their mood is highly labile.

Meaning it's unstable.

Extremely unstable.

They can switch on a dime.

One minute, they can be laughing hysterically about how they're going to meet the president.

And the next, if you mention a sad memory, they can burst into tears crying about a husband who died 10 years ago.

Then, just as quickly, they can flip back to euphoria.

And the text mentions delusions and hallucinations are common.

Yes.

And they're usually mood congruent.

Meaning they match the mood.

Exactly.

So if they feel euphoric and powerful, they will have grandiose delusions.

I am the messiah, or I own this hospital and I can have you all fired, or I have a direct line to God.

Okay.

That's a very clear picture.

Let's move on to section four.

Eteology.

The big question.

Why does this happen?

The text mentions some psychosocial theories first, but they seem a bit dated.

They are, for the most part, more of a historical context now.

There were old psychoanalytic theories about faulty family dynamics,

theories about mothers who resented a child's autonomy so the child learned to be overly dependent.

And the manic defense theory.

That was the idea that mania is a massive, desperate denial of an underlying depression, acting too independent and too happy to hide feelings of worthlessness and dependency.

While they can be psychologically interesting to think about, they are not the cause of the disorder.

The modern focus is squarely on biology.

Absolutely.

The evidence is overwhelming that bipolar disorder is a biological brain disease.

So let's break that down.

First, the neurotransmitters.

It's the classic chemical imbalance theory, but with a bipolar twist.

We see excessive levels and activity of norepinephrine and dopamine.

Too much gas.

Way too much gas in the engine.

And often there's a relative deficiency in serotonin, which acts like the brain's braking system.

So you have too much accelerator and not enough brakes.

That's a recipe for mania.

But then the text goes deeper.

There is this ion dysregulation theory.

This is in box 26 to 5.

This seems really specific, and honestly it feels like the key to the whole thing.

This is the aha moment for a lot of students in understanding the cycle.

It gets down to the cellular level.

It involves the sodium potassium ATPase pump in your neurons.

Okay, walk us through the pump.

Basic biology refresher.

Think of this pump as the battery regulator for your neurons.

Its main job is to constantly pump sodium ions out of the cell and potassium ions into the cell.

This keeps the neuron in a stable, balanced, ready -to -fire state.

Okay, so the theory in bipolar disorder is that this pump is, what, broken?

It slows down.

It becomes sluggish and inefficient.

So the pump is sluggish.

What happens inside the neuron as a result?

Sodium, which is supposed to be pumped out, starts to accumulate inside the neuron.

When that positively charged sodium builds up, the neuron becomes unstable and irritable.

It's on a hair trigger.

It fires way too easily.

Doesn't need much stimulation at all to spark an action potential.

And that hyper excitability of all the neurons in your brain?

That's mania.

Your brain is firing on all cylinders uncontrollably.

Okay, that makes sense.

The pump is slow, sodium builds up, sparks are flying everywhere, mania.

But then how does that lead to the other pole, to depression?

Well, think of it like an engine that's been redlining for too long.

If the pump continues to fail and can't keep up, eventually the neuron just runs out of energy.

The battery dies.

It can't maintain its electrical potential.

Neurotransmitter release drops off dramatically.

And that system -wide crash, that neuronal exhaustion.

Yeah, it is depression.

That's the depressive phase.

That is fascinating.

It's the first theory I've heard that actually explains why the two poles are so physiologically connected.

It's the same broken mechanism, just at two different stages of failure.

Exactly, it connects the dots beautifully.

And it also helps explain why a medication like lithium works.

Lithium is a salt, very similar to sodium, and it can help to stabilize that ion transport.

Which leads us directly to genetics.

A huge undeniable factor.

The genetic loading for bipolar disorder is one of the strongest in all of psychiatry.

If you have an identical twin with bipolar disorder, your risk is somewhere between 40 % and 80%.

Up to 80%, that is an incredibly high concordance rate.

It's massive.

If one parent has it, a child has about a 25 % risk.

If both parents have it, the risk jumps to 50 -75%.

It runs in families, and it runs strong.

Which brings us to another issue that often runs in families.

Comorbidity.

Section 5 in the text is all about the substance abuse connection.

And this is a massive complication in treatment.

The text is very clear.

Bipolar patients abuse alcohol and drugs more than any other DSM -5 diagnosis group.

The numbers are staggering.

Over 50 % have a lifetime history of alcohol abuse alone.

Why is that connection so strong?

The text offers four main hypotheses.

Right.

The first one is that it's simply a symptom of the disorder itself.

It's part of the impulsivity and poor judgment of mania.

I'm manic.

I feel invincible.

I want to party.

Let's drink and use cocaine.

Makes sense.

What's the second one?

Self -medication.

This is a very common theory.

The person is trying to regulate their own moods.

I feel too high.

I'm too agitated.

I need to bring it down with alcohol or benzodiazepines.

Or conversely, I'm in a deep depression.

I can't get out of bed.

I need cocaine or amphetamines just to get up and function.

And the third and fourth hypotheses.

The third is that in some cases, the substance abuse might actually cause or trigger the onset of the bipolar disorder in someone who was already vulnerable.

And the fourth is that there are shared genetic risk factors.

A genetic vulnerability to both addiction and mood instability that are inherited together.

It's probably a mix of all four for different people.

Most likely, yes.

But regardless of the why, the consequence is severe and undeniable.

What does it do to treatment?

It leads to what we call treatment resistance.

The medications just don't work as well.

It's associated with an earlier age of onset for the disorder.

And tragically, as noted in Box 2626, it leads to many more hospitalizations and a much higher rate of suicide attempts.

So we have a patient who is acutely manic, potentially substance abusing and genetically predisposed.

We are the nurse walking onto the unit.

Section six, psychotherapeutic management.

What is our role?

Where do we even begin?

The text lays out three clear goals.

One, and this is the absolute priority.

Safety.

Get the acute mania under control.

Prevent harm to sell for others.

Two, prevent relapse.

This is the long -term goal.

And three, help them return to their prior level of functioning in their family, work, and community.

Let's talk about the nurse -patient relationship.

This seems like the hardest part.

How do you talk to someone who is speaking in rhymes, pacing the halls, and thinks they are the president?

You have to adopt a very specific tone.

The textbook calls it a matter -of -fact tone.

This is essential to avoid getting into power struggles.

You can't be authoritative or bossy because they will push back.

But you also can't be overly emotional or wishy -washy.

You need to be calm, firm, and completely consistent.

And what about giving directions?

Clear,

simple, and concise.

Manic patients cannot process long discussions or complex reasoning.

Their brain is moving too fast.

So you keep it short.

Not, John, it would be a good idea if you considered putting on your shoes because we're going to the dining room soon.

It's just, John, put on your shoes.

Now, the text says something interesting about interrupting the patient, that the nurse may actually need to put a hand up and say, wait a minute, that feels so rude.

It feels rude, but it's therapeutically necessary.

The pause in conversation will never come naturally from a patient with pressured speech.

You have to create that pause to maintain any kind of structure.

You can say it gently.

I don't want to be rude, but I need to speak now or hold on.

We'll make sure I understand.

You have to interrupt to manage the flow.

And limit setting.

This seems key with the manipulation.

It's everything.

And the rules are simple.

Do not argue.

Do not debate unit rules.

Yeah.

If the patient says, why is curfew at 10?

You do not get into a long explanation about safety and staffing.

You simply state the policy and move on.

The rule is curfew is at 10.

Arguing or debating just reinforces their manipulative behavior.

Okay.

Moving from communication to milieu management, managing the actual environment.

Safety first.

Always.

You have to remove any potentially dangerous objects from the environment.

Manic patients can become very aggressive and impulsive, especially when limits are set.

And number two, reduce stimuli.

Get them away from the noise.

Yes.

No loud TV.

No loud music.

Get them away from the high traffic nurses station.

Provide a quiet place.

Maybe their room where their brain can have a chance to slow down.

Over stimulation is like fuel for mania.

And consistency among the staff.

Absolutely critical.

The entire staff must be on the same page about the rules and the plan of care.

This prevents that splitting behavior we talked about.

Where the patient pits one nurse against another to get what they want.

What about activities?

They have all this energy.

You have to channel it.

The book recommends gross motor activities.

Things like walking with a staff member.

Or folding laundry.

Or sweeping.

Repetitive, non -competitive tasks that can help them safely discharge some of that physical energy.

Why not competitive games?

Because they can be too stimulating and can easily trigger frustration, agitation, and aggression if they don't win.

So a basketball game is a bad idea, but shooting hoops by themselves might be okay.

That brings us to section seven, which is all about those really basic, but critical nursing interventions for physical health.

You can't neglect the physiology.

Nutrition is a huge one.

The problem is simple.

The patient is too busy to eat.

They won't sit down for a meal.

So what's the fix?

How do you get calories into them?

Finger foods.

High protein, high calorie foods they can eat on the move.

Sandwiches, protein bars, cheese sticks, milkshakes.

Things they can eat while they're pacing the halls.

You have to bring the food to them in a form they can actually consume.

You have to monitor it closely.

Encourage rest periods during the day, even if they don't sleep.

And at night, create a calm down ritual.

No caffeine, a quiet area.

Profound physical exhaustion can actually lead to death in rare cases.

So sleep is not optional.

And what about basic hygiene?

You have to help them.

Simple concrete reminders.

John, it's time to brush your teeth.

Mary, let's go put on a clean shirt.

And you also have to monitor for that flamboyant or sexually suggestive dress that might embarrass the patient later when they are no longer manic.

You can gently guide them to dress more appropriately for the setting.

Now let's talk about the heavy hitters.

Section 8, psychopharmacology.

What are the medications we are giving these patients?

The classic, the one everyone learns first, is lithium.

It's considered the gold standard mood stabilizer.

It's a naturally occurring element, a salt, very similar to sodium in the body.

But it's tricky to use, right?

It has a narrow therapeutic index.

Very tricky.

This is a major safety point for nurses.

The therapeutic blood level is very narrow, between 0 .6 and 1 .2 Meaql.

A little below that and it doesn't work.

A little above that and it becomes toxic, which can be lethal.

So that means frequent blood draws.

Yes, especially at first.

And crucial patient education is needed.

Around what?

They need to maintain a consistent salt and fluid intake.

If they suddenly cut out salt or get dehydrated from sweating, their body will hold on to the lithium to compensate.

And their levels can quickly become toxic.

What about anticonvulsants?

The tech says they're used a lot now.

They are.

They also work as mood stabilizers and are often used when lithium isn't tolerated or isn't effective enough.

The big one now is devolprox sodium, which you probably know as depotode.

In many places, it's actually prescribed more often than lithium now.

It's generally safer and has fewer side effects.

And there are others.

Yes, carbamazepine or digretol is another one.

And lamotrigine or lamictal.

A key point about lamictal is that it seems to be particularly good for

preventing the depressive phase of bipolar disorder, not just the mania.

And what about atypical antipsychotics?

Those are often used in the short term during an acute manic episode.

Medications like alansapine or risperidone.

They work quickly to help with sedation, to slow down the racing thoughts, and to treat any psychosis like delusions or hallucinations.

The tech says a very strong warning about using antidepressants.

Yes, and this is a huge point of caution.

Using a standard antidepressant, like an SSRI,

alone in a patient with bipolar depression is very controversial.

It can be like lighting a match.

It can push the patient straight out of depression and right into a manic or hypomanic episode.

So you have to use them with a mood stabilizer.

If you use them at all, they must be used in conjunction with a mood stabilizer to prevent that switch.

Finally, let's pull this all together.

Section 9 is on measurement and case study application.

How do we measure if someone is getting better?

We use rating scales.

The standard tool that the text highlights is the Young Mania Rating Scale, or the YMRS.

It's an 11 -item scale where a clinician reads the severity of manic symptoms.

What kind of things does it measure?

It measures all the things we've been talking about.

Elevated mood,

sexual interest, sleep specifically,

the patient's report that they don't need sleep irritability,

the rate and amount of their speech, and disruptive or aggressive behavior.

And a higher score means more severe mania.

Exactly.

You can track the score over time to see if the medications and interventions are working.

Okay, let's apply all this to the case study in the book, Casey Bates.

Right.

So Casey is a 50 -year -old attorney who gets admitted to the inpatient unit after getting into a bar fight.

What are his symptoms on admission?

Classic mania.

He's hyperactive, pacing, highly distracted.

He's showing flight of ideas, jumping from topic to topic.

And there are some paranoid and grandiose elements.

He's making hostile, racist remarks toward a Hispanic co -worker, claiming the co -worker is trying to ruin his career.

And he hasn't slept for three days.

So what's the initial nursing plan?

First, the nursing diagnoses.

The priorities are clearly risk for violence, both to self and others, and altered nutrition because he's not eating.

And the interventions.

All the things we've discussed.

Using a matter -of -fact tone,

providing a quiet room to decrease stimuli,

offering those high -calorie, high -protein finger foods, and of course, administering the prescribed medications, which in his case were lithium and an anti -psychotic, olandzapine.

And what's the outcome after a few days?

The plan is working, but it's a slow process.

He's less agitated, he's taking his medications, but he's still testing limits with the staff.

It shows that recovery from a full manic episode takes time and incredible consistency from the nursing team.

So let's wrap this incredible deep dive up.

If you had to summarize the absolute key takeaways for a nursing student, what would they be?

I'd say three things.

First, remember that bipolar is a biological, genetic, and cyclic disorder of the brain.

It's not a character flaw.

Second, in an acute manic state, your first priorities are always safety and physiological stability.

Maslow's hierarchy.

They need food, sleep, and a safe environment before any therapy can happen.

And the third.

Your communication must be firm, short, consistent, and calm.

You are the anchor in their storm.

And a final provocative thought to leave our listeners with.

I'd say let's go back to that ion dysregulation theory.

If our moods, our very experience of the world, can be boiled down to the speed of a tiny sodium pump inside a neuron,

how thin really is the line between what we call normal excitement and pathology?

It's a humbling thought about our own biology.

It really is.

Thanks for listening.
