Correct Answer is C

Explanation

To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..

So the nurse should add 250 mL of water to the formula to dilute it to half strength.

Correct Answer is C

Explanation

The patient is ordered to receive 0.15 mg/kg of Zofran over 15 minutes. The patient weighs 176 lb, which is equivalent to 80 kg. To calculate the total amount of Zofran the patient should receive, multiply the weight by the dosage:

80 kg x 0.15 mg/kg = 12 mg

The Zofran arrives from the pharmacy mixed in 50 mL of normal saline, which means there is 12 mg of Zofran in 50 mL of solution. To calculate how many milliliters per hour the nurse should set the IV pump, we can use the following formula:

50 mL / 0.25 hour = X mL per hour X = 200 mL per hour

Therefore, the nurse should set the IV pump to deliver 200 mL of Zofran per hour to the patient.
