The nurse is initiating a 500 mL IV of normal saline at 60 mL/hour for a client with heart failure. How many hours should the IV infuse? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["8.3"]
The correct answer is 8.3 hours. To find the answer, we can use the following formula:
(hours) = (mL of IV) / (mL/hour)
Substituting the given values, we get:
(hours) = (500) / (60)
Simplifying, we get:
(hours) = 8.333
(rounded hours) = 8.3
Therefore, the IV should infuse for 8.3 hours.

Correct Answer is ["20"]
Explanation
The correct answer is 20 mg. To find the answer, we can use the following steps:
- Convert the client'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) = (178) / (2.2) = 80.909 kg
- (dose in mg) = (0.25) x (80.909) = 20.227 mg
- (rounded dose in mg) = 20 mg
Therefore, the nurse should administer 20 mg of IV diltiazem to the client.
Correct Answer is ["400 mL\/hour"]
Explanation
To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (1000 / 150) x 60
Simplifying, we get:
(mL/hour) = 6.667 x 60
(mL/hour) = 400
Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.
