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

Answer and Explanation

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 C

Explanation

Choice A reason: An ID number alone lacks context; without name confirmation, it risks mismatching if wristbands are swapped, missing a critical identity check.

Choice B reason: Name alone may coincide with common names; without a unique identifier like a hospital number, this method risks errors in a busy unit.

Choice C reason: Name and hospital number provide dual identifiers; this matches the MAR precisely, ensuring accuracy for an unconscious patient per safety standards.

Choice D reason: Calling an unconscious patient is futile; they can’t respond, making this impractical and unreliable compared to objective wristband verification.

A. Therapeutic effects B. Chemical composition C. Mechanism of actions D. Side effects

Correct Answer is A

Explanation

Choice A reason: Therapeutic effects define expected outcomes; knowing these (e.g., pain relief) lets the nurse assess if the drug meets its clinical goal effectively.

Choice B reason: Chemical composition informs structure, not outcome; it’s irrelevant to evaluating if the drug achieves its intended physiological effect directly.

Choice C reason: Mechanism explains how drugs work; it’s useful but secondary to knowing the actual therapeutic result needed for outcome assessment.

Choice D reason: Side effects monitor safety, not efficacy; they don’t directly measure if the drug achieves its primary therapeutic purpose as intended.
