See the syringe diagram, what part is #7? (Assuming #7 refers to a common syringe part; no diagram provided, so standard parts assumed.)

Barrel

Plunger

Needle

Tip

Answer and Explanation

The Correct Answer is B

Choice A reason: The barrel holds the medication; it’s the main body, not typically #7, and its static role doesn’t involve direct manipulation like other parts.

Choice B reason: The plunger, often numbered high in diagrams, moves to draw or inject; its dynamic function in volume control makes it a likely #7 candidate.

Choice C reason: The needle pierces tissue; usually a lower number, it’s distinct from the syringe’s operational core, less likely to be #7 in standard layouts.

Choice D reason: The tip connects the needle; a minor component, it’s rarely highlighted as #7, overshadowed by the plunger or barrel in functional importance.

Correct Answer is C

Explanation

Choice A reason: Verbal instructions alone risk forgetting; arthritis may impair memory or dexterity, making a physical aid more effective for consistent adherence.

Choice B reason: Childproof caps hinder access; arthritic hands struggle with them, potentially causing missed doses rather than aiding safe administration.

Choice C reason: A pill organizer simplifies timing and dosage; it compensates for arthritis-related dexterity issues, ensuring accurate intake for a solo patient.

Choice D reason: Outdated drugs risk toxicity or inefficacy; keeping them confuses regimens, endangering the patient rather than supporting current treatment needs.

A. Deltoid and vastus lateralis B. Upper chest and abdomen C. Inner forearm and scapular area of the back D. Lower leg

Correct Answer is A

Explanation

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.
