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 ["0.5"]
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 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) = (132) / (2.2) = 60 kg
- (dose in mcg) = (5) x (60) = 300 mcg
- (volume in mL) = (300) / (480 / 0.8) = 0.5 mL
- (rounded volume in mL) = 0.5 mL
Therefore, the nurse should administer 0.5 mL of filgrastim to the client.
Correct Answer is ["240"]
Explanation
To find the answer, we can use the following steps:
- Calculate the amount of water needed to dilute the formula to 75% by subtracting the volume of the prescribed solution from the volume of the full strength formula
- Subtract the amount of water from the volume of the can to get the amount of enteral nutrition formula
- Round the result to the nearest whole number
Using these steps, we get:
- (water in mL) = (320) - (240) = 80 mL
- (enteral nutrition formula in mL) = (240) - (80) = 160 mL
- (rounded enteral nutrition formula in mL) = 160 mL
Therefore, the nurse should use 160 mL of enteral nutrition formula from the can to prepare the solution.
