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 ["9000"]

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

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

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (198) / (2.2) = 90 kg

- (dose in units) = (100) x (90) = 9000 units

- (rounded dose in units) = 9000 units

Therefore, the nurse should administer 9000 units of IV Heparin to the client.

Correct Answer is ["1.5"]

Explanation

The correct answer is 1.5 mL. To find the answer, we can use the following formula:

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

Substituting the given values, we get:

(mL to be administered) = (7.5) / (5)

Simplifying, we get:

(mL to be administered) = 1.5

Therefore, the nurse should administer 1.5 mL of metoclopramide from the prefilled syringe cartridge to the client.
