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 B

Explanation

Choice A reason: Pharmacy technicians are not authorized to administer medications. Their scope involves preparation and dispensing under supervision, ensuring safety and compliance.

Choice B reason: Safe practice standards dictate that the preparing nurse administers the medications to ensure accuracy and accountability, minimizing potential errors.

Choice C reason: Delegating to the head nurse violates medication administration protocols, as accountability rests with the nurse who prepared the medications.

Choice D reason: Allowing other licensed nurses to distribute medications increases the risk of errors due to lack of firsthand knowledge of preparation specifics.

A. Suggest total bed rest. B. Assist the patient when ambulating in the hall. C. Monitor intake and output. D. Instruct the resident to rise slowly when getting out of bed or a chair.

Correct Answer is D

Explanation

Choice A reason: Bed rest increases clot risk and deconditioning; vasodilators lower pressure, but mobility is beneficial unless contraindicated, making this overly restrictive.

Choice B reason: Assisting ambulation helps, but it’s less proactive; it doesn’t address orthostatic hypotension risks at initiation of movement, where falls are most likely.

Choice C reason: Monitoring intake/output tracks fluid status, not directly addressing vasodilation’s hypotensive effects during position changes, missing the primary safety concern.

Choice D reason: Rising slowly counters orthostatic hypotension from vasodilation; it allows autoregulation to stabilize pressure, reducing fall risk in an active elderly patient.
