The physician orders Zestril 15 mg po daily for hypertension. The medication is supplied in 5-mg tablets. How many tablets will the nurse administer?

1 tablet

2 tablets

3 tablets

4 tablets

Answer and Explanation

The Correct Answer is C

Choice A reason: One 5-mg tablet provides only 5 mg, far below the 15 mg ordered; this underdose fails to control hypertension effectively, risking cardiovascular complications like stroke or heart failure.

Choice B reason: Two tablets yield 10 mg, still short of 15 mg; this insufficient dose wouldn’t achieve therapeutic blood pressure reduction, leaving the patient at risk for hypertensive damage.

Choice C reason: Three 5-mg tablets equal 15 mg, matching the order precisely; this dose effectively inhibits angiotensin-converting enzyme, lowering blood pressure to a therapeutic range safely.

Choice D reason: Four tablets deliver 20 mg, exceeding the order; this overdose could cause hypotension, dizziness, or renal impairment due to excessive ACE inhibition beyond therapeutic needs.

Correct Answer is C

Explanation

Choice A reason: Verbal instructions alone risk forgetting; arthritis may impair memory or dexterity, making a physical aid more effective for consistent adherence.

Choice B reason: Childproof caps hinder access; arthritic hands struggle with them, potentially causing missed doses rather than aiding safe administration.

Choice C reason: A pill organizer simplifies timing and dosage; it compensates for arthritis-related dexterity issues, ensuring accurate intake for a solo patient.

Choice D reason: Outdated drugs risk toxicity or inefficacy; keeping them confuses regimens, endangering the patient rather than supporting current treatment needs.

A. "It is important to remember that herbal remedies do not have proven safety ratings for pregnant women." B. "Most herbal remedies are not harmful and are safe for use during pregnancy." C. "Keep in mind that products from different manufacturers are required to contain consistent amounts of the herbal products." D. "Please read each label carefully before use to check for cautionary warnings."

Correct Answer is A

Explanation

Choice A reason: Herbal remedies lack FDA safety data; in pregnancy, untested substances risk fetal harm (e.g., teratogenicity), making this a critical caution.

Choice B reason: Claiming safety is false; many herbs (e.g., St. John’s Wort) affect pregnancy adversely, and without evidence, this misleads the patient dangerously.

Choice C reason: Consistency isn’t required; herbal products vary widely in potency, and this false assurance ignores regulatory gaps in supplement standardization.

Choice D reason: Labels help, but warnings are inconsistent; this shifts responsibility without addressing the lack of proven safety, a more pressing prenatal concern.
