NUR 166 Chapter 29 Medication Administration Study Guide 2026 | 350+ Exam Questions & Correct Answers | Medication Safety, Injection Techniques, IV Therapy & Dosage Calculations | ECPI University

This comprehensive NUR 166 Chapter 29 Medication Administration Study Guide for 2026 contains more than 350 verified exam questions and correct answers covering medication administration, pharmacology fundamentals, injection techniques, IV therapy, dosage calculations, medication safety, drug absorption, therapeutic drug monitoring, and nursing responsibilities related to medication administration. The material provides extensive review content on adverse drug reactions (ADRs), allergic and anaphylactic reactions, pharmacokinetics, therapeutic and pharmaceutical drug classifications, intradermal, subcutaneous, and intramuscular injections, Z-track administration, medication rights, medication orders, IV push administration, inhalation medications, controlled substances, and nursing medication safety practices commonly taught in ECPI University NUR 166 and foundational nursing pharmacology courses. This study guide is highly relevant for students enrolled in NUR 166, Fundamentals of Nursing, Pharmacology for Nurses, Practical Nursing (PN), Licensed Practical Nursing (LPN), Associate Degree Nursing (ADN), Registered Nursing (RN), Medical-Surgical Nursing, Allied Health, and pre-NCLEX nursing preparation programs at colleges and universities. It is especially useful for ECPI University nursing students preparing for medication administration competency exams, dosage calculation assessments, injection safety evaluations, IV therapy testing, pharmacology examinations, and NCLEX-style medication safety questions. The content aligns closely with concepts discussed in Pharmacology and the Nursing Process by Lilley, Rainforth Collins, and Snyder, Fundamentals of Nursing by Potter and Perry, Clinical Nursing Skills and Techniques by Perry and Potter, and evidence-based medication administration standards published by organizations such as the Institute for Safe Medication Practices (ISMP), National Council of State Boards of Nursing (NCSBN), American Nurses Association (ANA), Centers for Disease Control and Prevention (CDC), and the Joint Commission. The material also reflects modern nursing medication safety protocols, IV therapy standards, and pharmacologic nursing practices used in acute care, outpatient, and long-term healthcare settings. The document extensively reviews pharmacology and medication administration concepts including drug absorption, distribution, adverse drug reactions (ADRs), allergic reactions, anaphylactic reactions, therapeutic drug ranges, peak and trough serum levels, drug half-life calculations, and pharmacologic classifications. Additional concepts include acidic versus basic drug absorption, oral medication absorption, intravenous administration as the fastest medication route, and intradermal administration as the slowest absorption route. The guide also explains pharmaceutical classifications based on mechanism of action (MOA), physiologic effects, and chemical structure, as well as therapeutic classifications such as analgesics, antibiotics, and antihypertensive medications. The study guide further provides detailed review material on injection administration techniques including intradermal (ID), subcutaneous (SubQ), and intramuscular (IM) injections. Topics reviewed include injection sites, needle lengths, gauge selection, injection angles, aspiration precautions, insulin syringe usage, and administration techniques such as the Z-track method. The material explains that intradermal injections are administered at a 10–15 degree angle using a tuberculin syringe with a 26–27 gauge needle, while subcutaneous injections are administered at 45–90 degree angles into adipose tissue using 25–27 gauge needles. Intramuscular injection concepts include ventrogluteal, deltoid, and pediatric vastus lateralis sites, perpendicular 90-degree administration, and IM medication volumes up to 3 mL. Additional medication administration concepts include ampules, multi-dose vials, medication expiration safety, controlled substance counts, medication preparation under adequate lighting, and safe medication label verification. The material also explores IV therapy, inhalation therapy, dosage calculations, and medication safety principles including peripheral IV flushing procedures, IV push medication administration, ongoing verification of IV infusion rates, metered-dose inhalers (MDIs), turbo-inhalers, and controlled medication handling. Dosage calculation concepts reviewed include converting grams to milligrams, converting pounds to kilograms, decimal movement rules, and formula-based medication calculations using “Dose on Hand ÷ Quantity on Hand = Dose Desired ÷ X.” Additional medication terminology reviewed includes AC (before meals), sustained action (SA), extended release (XR), controlled release (CR), and sustained release (SR) medications. The guide also explains medication administration safety practices including the Three Checks of medication administration, the Rights of Medication Administration, allergy assessment, patient education, medication refusal rights, documentation standards, and nursing responsibilities related to medication errors and patient safety. Additional nursing care concepts include breakthrough pain management, postsurgical analgesic administration, patient education for older adults, written medication instructions, IV complication monitoring, magnesium sulfate infusion assessments, aspiration precautions, and nursing assessment responsibilities before administering medications. Students using this resource will strengthen their understanding of medication administration, injection safety, pharmacology principles, IV therapy, dosage calculations, medication rights, patient education, and evidence-based nursing medication practices necessary for success in NUR 166 coursework and modern healthcare environments.
