A nurse is reinforcing teaching with a newly licensed nurse about transcribing medication prescriptions. Which of the following prescriptions should the newly licensed nurse identify as an accurate transcription?
Doxazosin .5 mg PO at bedtime
Lorazepam 0.5 mg PO PRN at bedtime
Heparin 5000 U subcutaneous every 8 hr
MgSO4 10 g PO daily
The Correct Answer is C
A. Doxazosin .5 mg PO at bedtime is incorrect. The dose should be written as "0.5 mg" to include the leading zero, following proper medication administration guidelines.
B. Lorazepam 0.5 mg PO PRN at bedtime is incorrect. "PRN" should include a specific indication (e.g., anxiety, insomnia. for when it is to be administered.
C. Heparin 5000 U subcutaneous every 8 hr is correct. The prescription is clear and includes the correct dose, route, and frequency of administration.
D. MgSO4 10 g PO daily is incorrect. Magnesium sulfate is typically administered intravenously, not orally, unless specified otherwise for specific conditions, and the dosage is quite high for oral administration.

Correct Answer is C
Explanation
A. Thrombocytopenia: Neither atenolol nor nitroglycerin is commonly associated with thrombocytopenia. This is not the primary concern when these two medications are used together.
B. Dry cough: A dry cough is a known side effect of ACE inhibitors (e.g., enalapril), but it is not commonly associated with atenolol or nitroglycerin.
C. Hypotension: Both atenolol (a beta-blocker) and nitroglycerin (a vasodilator) can lower blood pressure. When taken together, there is an increased risk of hypotension, especially when standing up quickly. The nurse should monitor the client for symptoms of low blood pressure such as dizziness, fainting, or lightheadedness.
D. Hyperglycemia: Atenolol may mask signs of hypoglycemia in clients with diabetes, but it does not directly cause hyperglycemia. Nitroglycerin is not typically associated with hyperglycemia either. Therefore, hyperglycemia is not a concern in this scenario.
Correct Answer is D
Explanation
A. Leaving noninvasive equipment on the client’s body is not appropriate during postmortem care. Tubing and devices should be removed unless an autopsy is required.
B. Dentures should generally be left in place to maintain the natural shape of the face and promote a more normal appearance for family viewing.
C. Turning the lights up is unnecessary and may create a harsh environment. A calm, respectful setting with normal or dim lighting is preferred during postmortem care.
D. Closing the client’s eyes before the family views the body helps provide a peaceful and dignified appearance and is an important part of postmortem care.
