A prescription calls for one capsule of a medication to be administered PO a.c. daily for 14 days. What directions should appear on the label?

Rationale

Take one capsule by mouth before a meal once daily for 14 days.

The prescription specifies "PO a.c.," indicating that the medication should be taken by mouth (PO) before meals (a.c. stands for ante cibum, Latin for "before meals"). Thus, the correct instructions on the label must reflect this timing and dosage.

A (Take one capsule by mouth daily for 14 days) YOUR ANSWER

This choice lacks the crucial detail regarding the timing of ingestion relative to meals. While the dosage and duration are correct, the absence of the "before meals" instruction makes it inaccurate according to the prescription.

B (Take one capsule by mouth after a meal once daily for 14 days) YOUR ANSWER

This option contradicts the prescription by indicating that the medication should be taken after a meal. The "a.c." in the prescription clearly specifies that the medication must be taken before meals, rendering this choice incorrect.

C (Take one capsule by mouth before a meal once daily for 14 days) CORRECT

This choice accurately reflects the prescription's instructions, specifying both the correct method of administration (by mouth) and the timing (before meals), along with the dosage and duration required.

D (Take one capsule by mouth with a meal once daily for 14 days) YOUR ANSWER

Similar to choice B, this option misrepresents the timing by stating that the medication should be taken with a meal. The prescription’s "a.c." explicitly indicates that the capsule must be taken before meals, making this choice incorrect.

Conclusion

The prescription's instructions are clear in specifying the administration of the medication before meals. The correct label should state to take one capsule by mouth before a meal once daily for 14 days, as this aligns with the directive of "PO a.c." Choices A, B, and D fail to maintain the necessary timing relative to meals, thus confirming C as the only accurate option.
