In addition to the dorsogluteal and ventrogluteal muscles, which of these sites can safely be used for intramuscular injections?
Deltoid and vastus lateralis
Upper chest and abdomen
Inner forearm and scapular area of the back
Lower leg
The Correct Answer is A
Choice A reason: Deltoid and vastus lateralis are large muscles with good vascularity; they safely absorb IM injections, minimizing nerve damage or tissue irritation risks.
Choice B reason: Chest and abdomen lack sufficient muscle mass for IM; these are subcutaneous or IV sites, risking poor absorption or injury if used intramuscularly.
Choice C reason: Forearm and scapula are too thin or bony; IM injections here risk nerve or bone damage, lacking the muscle bulk needed for safe drug delivery.
Choice D reason: Lower leg (e.g., calf) has small muscles and major vessels; IM use risks vascular injury or slow absorption, making it an unsafe injection site.

Correct Answer is A
Explanation
Choice A reason: Classifications like “analgesics” pair effects (pain relief) with symptoms (pain); this pharmacological basis groups drugs by therapeutic purpose and mechanism.
Choice B reason: Dosage varies within classes; it’s not a defining trait, as classifications focus on action (e.g., beta-blockers), not specific amounts administered.
Choice C reason: Tolerance is patient-specific, not a classification criterion; drugs are grouped by effect and symptom relief, not individual response variations.
Choice D reason: Nursing implications guide administration, not classification; categories stem from pharmacology (e.g., antihypertensives), not care protocols or implications.
Correct Answer is B
Explanation
Choice A reason: Showing the client isn’t a standard check; patients don’t verify MAR, and this step lacks relevance to the nurse’s triple-check safety protocol.
Choice B reason: Checking before returning ensures accuracy; the third check confirms the right drug post-administration, completing the three-point verification process safely.
Choice C reason: Calling the pharmacy is unrelated; label checks occur during administration, not external consultation, making this an irrelevant timing option.
Choice D reason: Colleague checks aren’t routine; the three checks are individual, and this step doesn’t align with standard MAR verification timing protocols.
