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
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: Checking with another nurse may occur, but it’s not mandatory for all schedule II drugs; documentation is the primary legal responsibility to track controlled substances accurately.
Choice B reason: Signing out on a narcotic sheet is required; schedule II drugs like opioids need strict tracking to prevent diversion, ensuring accountability per federal and hospital regulations.
Choice C reason: Leaving medication at the bedside violates security; schedule II drugs must remain controlled, as unattended narcotics risk theft or misuse, breaching safety protocols entirely.
Choice D reason: Extra water is irrelevant to responsibility; it’s a hydration tip, not a legal or safety duty tied to administering highly regulated schedule II controlled substances.
Correct Answer is B
Explanation
Choice A reason: Waiting delays care; illegible orders risk errors, and timely clarification ensures the patient receives accurate treatment without unnecessary postponement.
Choice B reason: Direct prescriber contact resolves ambiguity; it ensures the order’s intent, aligning with safety protocols to prevent misinterpretation or harm.
Choice C reason: Colleagues may guess incorrectly; peer opinion lacks authority, risking errors in dosage or drug, compromising patient safety over prescriber intent.
Choice D reason: Patient recall is unreliable; home meds may differ from admission orders, and this doesn’t clarify the prescriber’s handwritten instruction accurately.
