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 A
Explanation
Choice A reason: Lisinopril is Zestril’s generic name; an ACE inhibitor, it’s widely used for hypertension, matching the context of a common medication order.
Choice B reason: Acetaminophen, a pain reliever, isn’t Zestril’s generic; it lacks antihypertensive action, making it irrelevant to the implied medication class.
Choice C reason: Morphine, an opioid, treats pain, not hypertension; it doesn’t align with Zestril’s purpose or class, ruling it out as the generic name.
Choice D reason: Fentanyl, another opioid, addresses pain, not blood pressure; it’s unrelated to Zestril’s therapeutic role, excluding it from consideration.
Correct Answer is D
Explanation
Choice A reason: Positioning the tablet next to the cheek alters absorption and delays onset. Sublingual placement ensures rapid effect.
Choice B reason: Swallowing bypasses sublingual absorption, reducing efficacy. The route is critical for desired therapeutic outcomes.
Choice C reason: Crushing and dissolving disrupts integrity, compromising rapid sublingual absorption. Proper administration maintains efficacy.
Choice D reason: Sublingual placement allows rapid dissolution and absorption via mucous membranes, ensuring swift therapeutic action.
