A nurse is reviewing a client's prescriptions. The nurse should contact the provider to clarify which of the following prescriptions?
Phenytoin 100 mg PO every 8 hr.
Lisinopril 20 mg PO every 12 hr.
Hold for systolic BP less than 110 mm Hg.
Morphine 2.5 mg IV bolus PRN for incisional pain.
Regular insulin 7 units subcutaneous 30 min before breakfast and dinner.
The Correct Answer is C
Choice A rationale:
Phenytoin 100 mg PO every 8 hr is a standard prescription for controlling seizures.
Choice B rationale:
Lisinopril 20 mg PO every 12 hr is a typical dose for treating high blood pressure.
Choice C rationale:
“Hold for systolic BP less than 110 mm Hg” is unclear because it does not specify which medication to hold.
Choice D rationale:
Morphine 2.5 mg IV bolus PRN for incisional pain is a standard prescription for pain control after surgery.
Choice E rationale:
Regular insulin 7 units subcutaneous 30 min before breakfast and dinner is a common prescription for managing blood glucose levels in diabetes patients.
