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

Answer and Explanation

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: Zestril at 5 mg per tablet is common; strength is the dose per unit, and this matches typical labeling for hypertension management effectively.

Choice B reason: 10 mg is a Zestril strength but not assumed here; without label confirmation, 5 mg is the base unit from prior context, not this option.

Choice C reason: 15 mg isn’t standard for Zestril tablets; it’s a total dose possibility, not a per-tablet strength, mismatching typical medication packaging norms.

Choice D reason: 20 mg exists for Zestril but isn’t the default; 5 mg aligns with the supplied strength in earlier questions, making it the likely label.

A. 12-degree. B. 15-degree. C. 30-degree. D. 45-degree.

Correct Answer is B

Explanation

Choice A reason: A 12-degree angle is too shallow, increasing the risk of incorrect placement and ineffective administration of the intradermal injection.

Choice B reason: The 15-degree angle ensures precise intradermal placement, forming a wheal that indicates proper administration into the dermis for optimal absorption.

Choice C reason: A 30-degree angle places the medication too deep into subcutaneous tissue, compromising intended drug absorption.

Choice D reason: A 45-degree angle results in subcutaneous rather than intradermal injection, altering the drug’s effectiveness and purpose.
