The healthcare provider prescribes a hydration infusion of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 70 kg. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numeric value only.)
The Correct Answer is ["700"]
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 ["10 "]
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
- Multiply the weight in kilograms by the dosage in mg/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (35) / (2.2) = 15.909
- (dose in mg) = (0.6) x (15.909) = 9.545
- (rounded dose in mg) = 10
Therefore, the nurse should administer 10 mg of dexamethasone to the child.
Correct Answer is ["8"]
Explanation
The correct answer is 8 tablets. To find the answer, we can use the following steps:
- Convert the daily maximum dosage from grams to milligrams by multiplying by 1000
- Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet
- Round the result to the nearest whole number
Using these steps, we get:
- (daily maximum dosage in mg) = (5) x (1000) = 5000 mg
- (number of tablets) = (5000) / (625) = 8 tablets
- (rounded number of tablets) = 8
Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.
