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 D
Explanation
Choice A reason: Two-hour window (8:00-10:00) is too broad; most protocols allow 30 minutes before/after, as wider ranges risk altering drug pharmacokinetics significantly.
Choice B reason: One-hour window (8:30-9:30) is common but exceeds some strict policies; it’s less precise, potentially affecting drugs with tight timing needs.
Choice C reason: 8:30-9:00 is only before; it excludes post-9:00 flexibility, limiting administration to early dosing, which may not align with full protocol windows.
Choice D reason: 8:45-9:15 (30 minutes either side) fits standard policy; it ensures therapeutic levels for most drugs, balancing efficacy with practical scheduling.
Correct Answer is C
Explanation
Choice A reason: Four times (6:00 a.m., noon, 6:00 p.m., midnight) is QID, not TID; TID means three times daily, and this schedule overdoses the patient unnecessarily.
Choice B reason: Six times daily is every 4 hours, not TID; this exceeds the three-dose requirement, risking toxicity or side effects from excessive administration frequency.
Choice C reason: 9:00 a.m., 1:00 p.m., 5:00 p.m. is TID; spaced 8 hours apart, it aligns with standard three-times-daily dosing, ensuring consistent therapeutic levels safely.
Choice D reason: Meal and bedtime timing is vague; without fixed hours, it risks uneven dosing intervals, potentially disrupting pharmacokinetics and efficacy of the medication.
