(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 ["20"]

Explanation

The correct answer is 20 mg. To find the answer, we can use the following steps:

- Convert the client's weight from pounds to kilograms by dividing by 2.2

- Multiply the weight in kilograms by the dosage in mg/kg

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (178) / (2.2) = 80.909 kg

- (dose in mg) = (0.25) x (80.909) = 20.227 mg

- (rounded dose in mg) = 20 mg

Therefore, the nurse should administer 20 mg of IV diltiazem to the client.

Correct Answer is ["100"]

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) = (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.
