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.)
The Correct Answer is ["75"]
To find the answer, we can use the following steps:
- Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL
- Multiply the dose in mg per administration by the number of administrations per day
- Round the result to the nearest whole number
Using these steps, we get:
- (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg
- (total daily dose in mg) = (37.5) x (2) = 75 mg
- (rounded total daily dose in mg) = 75 mg
Therefore, the client receives 75 mg of diphenhydramine per day.

Correct Answer is ["0.4"]
Explanation
To find the answer, we can use the following formula:
(mL to be administered) = (units prescribed) / (units per mL)
Substituting the given values, we get:
(mL to be administered) = (240,000) / (1,200,000 / 2)
Simplifying, we get:
(mL to be administered) = (240,000 x 2) / (1,200,000)
(mL to be administered) = 480,000 / 1,200,000
(mL to be administered) = 0.4
Therefore, the nurse should administer 0.4 mL of penicillin G procaine to the child.
Correct Answer is ["0.7"]
Explanation
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the dose of filgrastim in mcg by multiplying the weight in kg by the dosage in mcg/kg/day
- Divide the dose in mcg by the concentration of filgrastim in mcg/mL
- Round the result to the nearest tenth
Using these steps, we get:
- (weight in kg) = (88) / (2.2) = 40 kg
- (dose in mcg) = (5) x (40) = 200 mcg
- (volume in mL) = (200) / (300) = 0.667 mL
- (rounded volume in mL) = 0.7 mL
Therefore, the nurse should administer 0.7 mL of filgrastim to this child daily.
