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 D
Explanation
Choice A reason: Administering insulin at proper timing correlates with mealtimes. However, this alone doesn't ensure safe practice.
Choice B reason: Confirming the injection site prevents lipodystrophy but does not address dose accuracy, which is vital for safety.
Choice C reason: Insulin is injected subcutaneously, not in the deltoid muscle. Using incorrect sites disrupts absorption.
Choice D reason: Double-checking insulin dose prevents administration errors, ensuring compliance with medication safety protocols.
Correct Answer is C
Explanation
Choice A reason: One 5-mg tablet provides only 5 mg, far below the 15 mg ordered; this underdose fails to control hypertension effectively, risking cardiovascular complications like stroke or heart failure.
Choice B reason: Two tablets yield 10 mg, still short of 15 mg; this insufficient dose wouldn’t achieve therapeutic blood pressure reduction, leaving the patient at risk for hypertensive damage.
Choice C reason: Three 5-mg tablets equal 15 mg, matching the order precisely; this dose effectively inhibits angiotensin-converting enzyme, lowering blood pressure to a therapeutic range safely.
Choice D reason: Four tablets deliver 20 mg, exceeding the order; this overdose could cause hypotension, dizziness, or renal impairment due to excessive ACE inhibition beyond therapeutic needs.
