Using the label, what is the strength of the medication? (No label; assuming Zestril from prior context.)
5 mg
10 mg
15 mg
20 mg
The Correct Answer is A
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.

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.
Correct Answer is B
Explanation
Choice A reason: Lungs excrete volatile drugs like anesthetics; most medications aren’t metabolized here, as they lack the cytochrome enzymes needed for broad drug breakdown.
Choice B reason: The liver is the primary site; cytochrome P450 enzymes metabolize most drugs, converting them into active or excretable forms, critical for pharmacokinetics.
Choice C reason: Kidneys excrete metabolites; they filter, not metabolize, most drugs, relying on prior liver processing, making them secondary in the metabolic pathway.
Choice D reason: The colon absorbs some drugs but doesn’t metabolize most; its role is minimal compared to the liver’s extensive enzymatic drug transformation capacity.
