A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hr to an older adult client who has rhinitis. The amount available is diphenhydramine syrup 12.5 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
A
Rationale
25 mg divided by 12.5 mg/5 mL = 10 mL, the correct dose based on the concentration.
