A patient who weighs 154 pounds receives a prescription for epoetin alfa 50 units/kg subcutaneously 3 times a week. The medication is available in 2000 units/mL vial. How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.9 mL"]

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 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.

Correct Answer is ["250 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) = (500 / 120) x 60

Simplifying, we get:

(mL/hour) = 4.167 x 60

(mL/hour) = 250

Therefore, the nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS to the patient.
