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.

Correct Answer is ["250"]
Explanation
The correct answer is 250 mg.
Step 1: Convert grams to milligrams. 1 gram = 1000 milligrams. So, 2 grams = 2000 milligrams.
Step 2: Divide the total milligrams by the number of doses. 2000 mg / 8 doses = 250 mg per dose.
Correct Answer is C
Explanation
Choice A rationale:
Anaphylaxis is not an unusual response due to an inherited predisposition. It’s an acute allergic reaction.
Choice B rationale:
Anaphylaxis is not a predictable and often unavoidable secondary effect that can occur at a usual therapeutic dose. It’s an unpredictable and severe allergic reaction.
Choice C rationale:
Anaphylaxis is indeed a severe hypersensitivity or allergic reaction that is life-threatening. It requires immediate medical attention.
Choice D rationale:
Anaphylaxis will not cause withdrawal symptoms when you discontinue taking the medication. It’s an immediate allergic reaction.
