Answer 9

Correct Answers:

Calcium carbonate 750 mg PO

Rationale :

🔹 A complete medication prescription must include medication name + dose + route + frequency.

🔹 Prescription written: Calcium carbonate 750 mg PO

🔹 Check components:

• Medication name ✔

• Dose ✔

• Route ✔

• Frequency ❌ Missing

🔹 Because frequency is absent (daily, BID, PRN, etc.), the prescription is incomplete and must be clarified before administration.

🔹 Administering an incomplete prescription can cause medication error or omitted therapy.

❌ Incorrect Options

Oxycodone 5 mg PO every 4 hr PRN for severe pain

🔹 This prescription includes medication, dose, route, frequency, and indication.

🔹 It is complete and appropriate for postpartum severe pain management.

Ibuprofen 600 mg PO every 6 hr PRN for moderate pain

🔹 This order contains all required components and is a common postpartum analgesic prescription.

🔹 There is no missing information that requires clarification.

Bisacodyl 10 mg rectal now

🔹 This prescription includes medication, dose, route, and timing (“now”), which serves as the frequency.

🔹 It is complete and does not need clarification.
