EXAMINATION STUDY GUIDE
▸ This document contains verified Q&A for NR 224 Exam 2 Weak Areas (2026/2027 Update).
▸ Covers medication administration routes (PO, SQ, IM, IV, ID, topical, ophthalmic, otic, transdermal, inhaler),
oxygen delivery devices, hypoxia assessment, urinary system assessment (catheters, urinalysis findings, voiding
patterns), BMI categories, physical assessment techniques (Allis, Phalen, Tinel), and congenital/genitourinary
conditions.
▸ Each answer includes clinical rationale based on evidence-based practice and Chamberlain University nursing
curriculum standards.
▸ Use this guide to prepare for the exam and for clinical application in foundational nursing practice.
SECTION I — MEDICATION ADMINISTRATION ROUTES & Q1–
TECHNIQUES Q14
1. What are nursing considerations for oral (PO) medication administration?
CORRECT ANSWER: Assess swallowing ability. DO NOT give if patient is vomiting, has dysphagia, or
decreased level of consciousness.
RATIONALE: Oral medications require intact gag reflex and ability to swallow. Risk of aspiration is high in patients
with dysphagia or altered LOC.
2. What is the angle of insertion for subcutaneous (SQ) injections?
CORRECT ANSWER: 45-90 degrees.
RATIONALE: Subcutaneous injections are given into adipose tissue layer. Use 45° for thin patients; 90° for
average/obese patients.
, 3. What is the maximum volume for a subcutaneous (SQ) injection?
CORRECT ANSWER: Maximum 3 mL.
RATIONALE: Larger volumes can cause tissue damage and poor absorption. Divide large doses into multiple
injections if needed.
4. What are the sites for intramuscular (IM) injections?
CORRECT ANSWER: Deltoid, vastus lateralis, ventrogluteal.
RATIONALE: Ventrogluteal is preferred for adults (no major nerves or blood vessels). Vastus lateralis is preferred for
infants and children. Deltoid is limited to small volumes (≤1-2 mL).
5. What is the maximum volume for intramuscular (IM) injection in infants?
CORRECT ANSWER: 0.5 mL.
RATIONALE: Infants have smaller muscle mass. Use vastus lateralis for infant IM injections.
6. What is the risk level for intravenous (IV) medication administration?
CORRECT ANSWER: Fast absorption = highest risk; requires close monitoring.
RATIONALE: IV medications enter bloodstream immediately. Adverse reactions can occur rapidly; monitor for
infiltration, phlebitis, and allergic reactions.
7. Where are transdermal patches typically applied?
CORRECT ANSWER: Trunk, lower abdomen, lower back, buttocks (hairless areas).
RATIONALE: Rotate application sites to prevent skin irritation. Clean and dry skin before application.
8. What is the angle of insertion for intradermal (ID) injections?
CORRECT ANSWER: 5-15 degrees.
RATIONALE: Intradermal injections are given just below epidermis. Forms a small wheel (bleb) - indicates correct
placement.
9. What is intradermal (ID) injection used for clinically?
CORRECT ANSWER: Used for TB testing (Mantoux test) and allergy testing; forms small wheel (bubble).
RATIONALE: Common sites: inner forearm, upper back. Do not massage or aspirate.
