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 the medication should be taken by mouth (PO) before meals (a.c., or "ante cibum"). This instruction is essential for ensuring the medication's effectiveness and minimizing potential gastrointestinal side effects.

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

This option correctly states the dosage and duration but omits the critical detail regarding timing in relation to meals. Without the specification that the capsule should be taken before meals, this instruction may lead to improper administration and could affect the medication's efficacy.

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

This choice completely contradicts the prescription's instructions. Taking the medication after a meal rather than before can significantly alter its absorption and effectiveness, potentially leading to reduced therapeutic outcomes or increased side effects.

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

This option accurately reflects the prescription's requirements. It explicitly states that the capsule should be taken before meals, which is critical for the intended effects of the medication. Adhering to this instruction ensures optimal absorption and therapeutic efficacy.

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

Like option B, this choice misinterprets the timing of the medication. Taking it with a meal rather than before can interfere with the absorption rate of the medication, potentially compromising its effectiveness and leading to unintended side effects.

Conclusion

The prescription clearly indicates that the medication must be taken before meals, as denoted by "PO a.c." This specificity is vital for ensuring the proper administration and therapeutic effect of the medication. Options A, B, and D fail to adhere to this requirement, highlighting the importance of precise language in medication instructions to prevent misadministration and to ensure patient safety.
