Answer 2

Correct Answers:

Fentanyl 25 mcg/hr transdermal patch

Rationale :

🩹 The nurse should contact the provider because the prescription does not include how often to change the fentanyl patch.

🩹 Fentanyl transdermal patches are usually changed on a scheduled interval, commonly every 72 hr, depending on the prescription and client response.

🩹 A complete medication prescription should include the medication name, dose, route, frequency, and specific administration instructions.

🩹 Since this order only states “25 mcg/hr transdermal patch,” the nurse needs clarification before administration to prevent medication error.

🩹 Fentanyl is a potent opioid, so unclear dosing instructions can increase the risk for respiratory depression, oversedation, overdose, or uncontrolled pain.

❌ Meloxicam 15 mg PO daily

❌ This prescription includes the medication, dose, route, and frequency.

❌ It is complete and does not require clarification.

❌ Regular insulin 8 units subcutaneous before meals

❌ This prescription includes the type of insulin, dose, route, and timing.

❌ “Before meals” provides an administration schedule.

❌ Docusate sodium 200 mg PO at bedtime

❌ This prescription includes the medication, dose, route, and time of administration.

❌ It is clear and complete.
