Chapter 10: Drug Administration Routes & Techniques

Drug Administration Routes & Techniques emphasizes that drug administration is a multidimensional process encompassing preparation, education, and the continuous evaluation of therapeutic outcomes to ensure patient safety. The text categorizes medication delivery into non-parenteral and parenteral routes, highlighting the clinical nuances of each. Oral administration is explored through tablets, capsules, and liquids, with a strict warning against crushing or splitting sustained-release or enteric-coated formulations due to the risk of life-threatening toxicity and rapid dose release. External application methods such as transdermal patches, topical ointments, and instillations for ocular, otic, and nasal care are detailed, stressing the importance of aseptic technique, personal protective equipment, and site rotation to prevent skin breakdown. Specialized delivery via gastric tubes, such as nasogastric or gastrostomy tubes, requires verification of tube placement and rigorous flushing protocols to maintain patency and prevent aspiration. The chapter also provides technical guidance on parenteral injections, including intradermal testing, subcutaneous fat-pad delivery, and intramuscular injections using the Z-track technique to minimize tissue irritation and staining. Significant attention is given to site selection, identifying the ventrogluteal muscle as the primary choice for most adults and children, while the vastus lateralis remains critical for pediatric immunizations. Throughout the material, the clinical judgment model is integrated to guide nurses in recognizing cues like drug allergies or aspiration risks, prioritizing patient needs, and implementing the essential "rights" of medication administration. Finally, the chapter addresses the unique developmental needs of pediatric patients, suggesting strategies like play therapy and the use of the least intrusive routes to reduce procedural anxiety and ensure safety in calculating appropriate dosages for smaller body sizes.
