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.)

Answer and Explanation

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 ["0.9"]

Explanation

The correct answer is 0.9 mL. To find the answer, we can use the following steps:

- Convert the patient's weight from pounds to kilograms by dividing by 2.2

- Multiply the weight in kilograms by the dosage in units/kg

- Divide the dose in units by the concentration in units/mL

- Round the result to the nearest tenth

Using these steps, we get:

- (weight in kg) = (154) / (2.2) = 70 kg

- (dose in units) = (50) x (70) = 3500 units

- (volume in mL) = (3500) / (2000) = 1.75 mL

- (rounded volume in mL) = 1.8 mL

Therefore, the nurse should administer 1.8 mL of epoetin alfa from the vial to the patient.

Correct Answer is ["400"]

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.
