The healthcare provider prescribes penicillin 200,000 units intramuscularly for a patient with pneumonia.
The available vial is labeled “Penicillin 500,000 units/mL”. How much penicillin should be administered to the patient? (Enter numerical value only.
If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.4"]
Step 1 is to determine the amount of penicillin in each milliliter (mL) of the available solution. The vial is labeled as “Penicillin 500,000 units/mL”.
Step 2 is to divide the prescribed dose by the concentration per mL. So, the calculation is 200,000 units ÷ 500,000 units/mL. The result is 0.4 mL.

Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Checking the fingerstick glucose level is an immediate action that the nurse should take when a patient with type 2 diabetes reports feeling weak and jittery. These symptoms could indicate hypoglycemia, a condition characterized by low blood sugar levels.
Choice B rationale
Assessing skin temperature and moisture can help the nurse determine if the patient is sweating, a common symptom of hypoglycemia.
Choice C rationale
Administering a PRN dose of regular insulin is not the appropriate action if the patient is experiencing symptoms of hypoglycemia. Insulin would further lower the patient’s blood sugar levels, potentially worsening their condition.
Choice D rationale
Documenting anxiety on the surgical checklist may not be immediately helpful in addressing the patient’s current symptoms. While it’s important to document all relevant information, the nurse’s immediate focus should be on assessing and managing the patient’s symptoms.
Choice E rationale
Measuring pulse and blood pressure can provide important information about the patient’s cardiovascular status. Hypoglycemia can cause tachycardia and potentially hypotension, so these vital signs should be monitored.
