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 ["700 mL\/hour"]
Explanation
To find the answer, we can use the following steps:
- Calculate the total volume of normal saline in mL by multiplying the weight in kg by the dosage in mL/kg
- Divide the total volume of normal saline in mL by the number of hours to get the rate in mL/hour
- Round the result to the nearest whole number
Using these steps, we get:
- (total volume in mL) = (30) x (70) = 2100 mL
- (rate in mL/hour) = (2100) / (3) = 700 mL/hour
- (rounded rate in mL/hour) = 700 mL/hour
Therefore, the nurse should program the infusion pump to deliver 700 mL/hour of normal saline.
Correct Answer is ["21"]
Explanation
To find the answer, we can use the following formula:
(gtt/min) = (mL/hour) x (gtt/mL) / 60
Substituting the given values, we get:
(gtt/min) = (500 / 4) x (10) / 60
Simplifying, we get:
(gtt/min) = 125 x 10 / 60
(gtt/min) = 20.833
(rounded gtt/min) = 21
Therefore, the nurse should regulate the infusion to deliver 21 gtt/minute of 0.9% normal saline.
