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 mL"]

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 ["0.5 mL"]

Explanation

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

- Calculate the dose of dalteparin in units by multiplying the weight in kg 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:

- (dose in units) = (60) x (200) = 12,000 units

- (volume in mL) = (12,000) / (25,000) = 0.48 mL

- (rounded volume in mL) = 0.5 mL

Therefore, the nurse should administer 0.5 mL of dalteparin from the vial to the client.

Correct Answer is ["0.4 mL"]

Explanation

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

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

Substituting the given values, we get:

(mL to be administered) = (240,000) / (1,200,000 / 2)

Simplifying, we get:

(mL to be administered) = (240,000 x 2) / (1,200,000)

(mL to be administered) = 480,000 / 1,200,000

(mL to be administered) = 0.4

Therefore, the nurse should administer 0.4 mL of penicillin G procaine to the child.
