Question 1 of 5
Order: diphenhydramine 25 mg PO q6h, PRN Available: diphenhydramine 12.5 mg/5 mL. How many mL would the nurse give?
Correct Answer: D
Rationale: The correct answer is D: 10 mL.
To calculate the mL needed, first determine how many mg are needed per dose (25 mg).
Then, use the available concentration (12.5 mg/5 mL) to set up a proportion: 25 mg = x mL. Cross multiply to find x = 10 mL. Other choices are incorrect due to incorrect calculations or misinterpretation of the available concentration.
