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 ["180"]
Explanation
To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Calculate the dosage of dobutamine in mg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60
- Divide the dosage of dobutamine in mg/hour by the concentration of dobutamine in the solution in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (165) / (2.2) = 75 kg
- (dose in mg/hour) = (2) x (75) x (60) = 9000 mcg/hour
- (dose in mg/hour) = (9000 x 10^-3) = 9 mg/hour
- (volume in mL/hour) = (9) / (50 / 1000) = 180 mL/hour
Therefore, the nurse should set the infusion pump to deliver 180 mL/hour of dobutamine hydrochloride in D5W.
Correct Answer is ["0.5"]
Explanation
The correct answer is 0.5 mL. To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (200) / (1000 / 2.5)
Simplifying, we get:
(mL to be administered) = (200) x (2.5 / 1000)
(mL to be administered) = 0.5
Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.
