Correct Answer is D

Explanation

The correct answer is choice D. Regular insulin 35 units subcutaneously 30 minutes before meals.

Choice A rationale:

Desvenlafaxine 50 mg PO daily is a standard dosage for this antidepressant medication and does not typically require clarification unless there are specific patient concerns or contraindications.

Choice B rationale:

Ketorolac nasal spray, one spray in each nostril every 6 hours as needed for moderate pain, is an appropriate prescription. However, it is important to monitor for potential side effects, especially with prolonged use.

Choice C rationale:

Oxycodone 10 mg PO every 4 hours as needed for severe pain is a common prescription for managing severe pain. The nurse should ensure the patient is monitored for signs of opioid misuse or adverse effects.

Choice D rationale:

Regular insulin 35 units subcutaneously 30 minutes before meals is an unusually high dose and could lead to hypoglycemia. This prescription should be clarified with the provider to ensure it is accurate and safe for the patient.

Correct Answer is ["2 "]

Explanation

The nurse should administer 2 mL of benzathine penicillin G. Here’s the calculation: Step 1: The total dosage required is 1,200,000 units.

Step 2: Each mL of the injection contains 600,000 units of benzathine penicillin G.

Step 3: So, the volume to be administered is 1,200,000 units ÷ 600,000 units/mL = 2 mL.
