A nurse is preparing to administer an intramuscular injection for a client of average weight. At what angle would the nurse insert the needle?
90-degree
45-degree
15-degree
25-degree
The Correct Answer is A
Choice A reason: IM injections use a 90-degree angle; this ensures deep muscle penetration for average-weight adults, optimizing drug absorption into vascular tissue.
Choice B reason: 45 degrees is for subcutaneous injections; it’s too shallow for IM, risking fat deposition instead of muscle, reducing efficacy in this context.
Choice C reason: 15 degrees is far too shallow; it’s not a standard angle, likely depositing drug in skin layers, failing to reach muscle for intended absorption.
Choice D reason: 25 degrees mimics subcutaneous; it doesn’t reach muscle depth, compromising IM delivery and therapeutic effect in an average-weight client.

Correct Answer is D
Explanation
Choice A reason: PRN is as needed; EKGs here are routine, not symptom-driven, making this inapplicable to a standard admission protocol for all patients.
Choice B reason: One-time is a single event; this order applies to all admissions ongoing, not a one-off, distinguishing it from limited-duration directives.
Choice C reason: STAT is immediate; routine EKGs aren’t urgent, occurring as part of standard care, not requiring the priority of acute intervention orders.
Choice D reason: Standing orders apply automatically to all qualifying patients; this EKG protocol fits, ensuring consistent cardiac assessment unless overridden.
Correct Answer is C
Explanation
Choice A reason: Toxic effects involve overdose symptoms like coma; staying awake isn’t toxicity, as Nembutal’s sedative intent is reversed, not exaggerated, in this reaction.
Choice B reason: Drug allergy causes immune responses (e.g., rash); insomnia isn’t allergic, but a paradoxical effect, differing from hypersensitivity reactions entirely.
Choice C reason: Idiosyncrasy is an unexpected reaction; Nembutal, a barbiturate, should sedate, but wakefulness is an abnormal, individual response, fitting this category precisely.
Choice D reason: Tolerance reduces efficacy over time; this acute, opposite reaction to a sedative isn’t tolerance, but an immediate, unpredictable drug response.
