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 C
Explanation
Choice A reason: Informing the patient is secondary; it addresses communication but not immediate safety risks like needlestick injury, which is a higher priority post-injection per occupational health standards.
Choice B reason: Assessing comfort is important but not urgent; pain evaluation can wait after securing the needle, as safety from sharps exposure outweighs immediate patient feedback in priority.
Choice C reason: Engaging the safety sheath prevents needlestick injuries; it’s the priority action to protect the nurse and others from bloodborne pathogens, aligning with universal precautions post-injection.
Choice D reason: Checking for bleeding is routine but not critical; minor oozing is common and manageable later, while needle safety is an immediate concern to prevent infection risks.
Correct Answer is B
Explanation
Choice A reason: Calling the name relies on response accuracy; confused or hearing-impaired patients may not answer correctly, risking misidentification and medication errors.
Choice B reason: Verbal confirmation plus armband verification against the MAR ensures identity via two identifiers, aligning with safety protocols to prevent administration errors scientifically.
Choice C reason: Family or visitors may misidentify due to stress or error; this lacks direct patient verification, increasing risk of giving medication to the wrong individual.
Choice D reason: Bed or door labels can be outdated or misplaced; this indirect method fails to confirm identity actively, heightening the chance of medication misadministration.
