A pediatric client with cerebral palsy receives a prescription for a 75% enteral nutrition formula of 320 mL to infuse at 80 mL/hour via an enteral feeding pump. The formula is available full strength in a 240 mL can. To prepare the solution, the nurse should use how many mL of the enteral nutrition formula?
(Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["240"]

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.

Correct Answer is ["1200"]

Explanation

To find the answer, we can use the following formula:

(units of heparin) = (mL/hour) x (hours) x (units per mL)

Substituting the given values, we get:

(units of heparin) = (25) x (12) x (20,000 / 500)

Simplifying, we get:

(units of heparin) = (25) x (12) x (40)

(units of heparin) = 1200

Therefore, the client should receive 1200 units of heparin in 12 hours.

Correct Answer is ["100"]

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) = (150 / 90) x 60

Simplifying, we get:

(mL/hour) = 1.667 x 60

(mL/hour) = 100

Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.
