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"]

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 ["8"]

Explanation

The correct answer is 8 tablets. To find the answer, we can use the following steps:

- Convert the daily maximum dosage from grams to milligrams by multiplying by 1000

- Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet

- Round the result to the nearest whole number

Using these steps, we get:

- (daily maximum dosage in mg) = (5) x (1000) = 5000 mg

- (number of tablets) = (5000) / (625) = 8 tablets

- (rounded number of tablets) = 8

Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.

Correct Answer is ["15"]

Explanation

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

(number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed)

Substituting the given values, we get:

(number of doses) = (18) / (1.2)

Simplifying, we get:

(number of doses) = 15

Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.
