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 ["83 gtt\/min"]

Explanation

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

(gtt/min) = (mL/hour) x (gtt/mL) / 60

Substituting the given values, we get:

(gtt/min) = (1000 / 12) x (60) / 60

Simplifying, we get:

(gtt/min) = 83.333

(rounded gtt/min) = 83

Therefore, the nurse should regulate the infusion to deliver 83 gtt/minute of lactated Ringer's.

Correct Answer is ["240 mL"]

Explanation

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

- Calculate the amount of water needed to dilute the formula to 75% by subtracting the volume of the prescribed solution from the volume of the full strength formula

- Subtract the amount of water from the volume of the can to get the amount of enteral nutrition formula

- Round the result to the nearest whole number

Using these steps, we get:

- (water in mL) = (320) - (240) = 80 mL

- (enteral nutrition formula in mL) = (240) - (80) = 160 mL

- (rounded enteral nutrition formula in mL) = 160 mL

Therefore, the nurse should use 160 mL of enteral nutrition formula from the can to prepare the solution.
