Question 21 :
An adult client receives a prescription for diphenhydramine 15 mL by mouth every 12 hours PRN for pruritus. The bottle is labeled, diphenhydramine 12.5 mg/5 mL. What is the total daily dose in mg that the client receives? (Enter numerical value only.)
Correct Answer: ["75 mg"]
To find the total daily dose in mg, we need to multiply the dose per administration by the number of administrations per day and convert the units from mL to mg. The dose per administration is 15 mL, and the number of administrations per day is 2 (every 12 hours). The conversion factor from mL to mg is given by the label, which is 12.5 mg/5 mL. Therefore, the total daily dose in mg is (15 mL x 2 x 12.5 mg/5 mL) = 75 mg.
