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 ["0.6 mL"]

Explanation

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

(mL to be administered) = (mg prescribed) / (mg per mL)

Substituting the given values, we get:

(mL to be administered) = (150) / (250)

Simplifying, we get:

(mL to be administered) = 0.6

Therefore, the nurse should administer 0.6 mL of hydrocortisone sodium succinate to the patient.

Correct Answer is ["700 mL\/hour"]

Explanation

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

- Calculate the total volume of normal saline in mL by multiplying the weight in kg by the dosage in mL/kg

- Divide the total volume of normal saline in mL by the number of hours to get the rate in mL/hour

- Round the result to the nearest whole number

Using these steps, we get:

- (total volume in mL) = (30) x (70) = 2100 mL

- (rate in mL/hour) = (2100) / (3) = 700 mL/hour

- (rounded rate in mL/hour) = 700 mL/hour

Therefore, the nurse should program the infusion pump to deliver 700 mL/hour of normal saline.
