The healthcare provider prescribes cefazolin 800 mg IM every six hours. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, "For IM use add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL." After reconstitution, the solution contains how many mg/mL? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["333"]

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

(mg/mL) = (mg of cefazolin) / (mL of solution)

Substituting the given values, we get:

(mg/mL) = (1000) / (3)

Simplifying, we get:

(mg/mL) = 333.333

(rounded mg/mL) = 333

Therefore, after reconstitution, the solution contains 333 mg/mL of cefazolin.

Correct Answer is ["18 mL\/hour"]

Explanation

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

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

- Calculate the dosage of dobutamine in mg/hour by multiplying the weight in kg by the rate in mcg/kg/min and by 60

- Divide the dosage of dobutamine in mg/hour by the concentration of dobutamine in the solution in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (165) / (2.2) = 75 kg

- (dose in mg/hour) = (2) x (75) x (60) = 9000 mcg/hour

- (dose in mg/hour) = (9000 x 10^-3) = 9 mg/hour

- (volume in mL/hour) = (9) / (50 / 1000) = 180 mL/hour

- (rounded volume in mL/hour) = 18 mL/hour

Therefore, the nurse should set the infusion pump to deliver 18 mL/hour of dobutamine hydrochloride in D5W.

Correct Answer is ["30 mL"]

Explanation

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.
