The healthcare provider prescribes lamivudine oral solution 150 mg twice daily for a client who is HIV positive. The available bottle contains 240 mL of lamivudine labeled, "10 mg/mL." How many mL should the nurse administer in a 24 hour period?
(Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["30"]

The correct answer is 30 mL. To find the answer, we can use the following steps:

- Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations

- Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

- (total daily dose in mg) = (150) x (2) = 300 mg

- (volume to be administered in mL) = (300) / (10) = 30 mL

- (rounded volume to be administered in mL) = 30 mL

Therefore, the Nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.

Correct Answer is ["100"]

Explanation

The correct answer is 100 mL/hour. To find the answer, we can use the following formula:

(mL/hour) = (mL/minute) x 60

Substituting the given values, we get:

(mL/hour) = (150 / 90) x 60

Simplifying, we get:

(mL/hour) = 1.667 x 60

(mL/hour) = 100

Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.

Correct Answer is ["240"]

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.
