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 ["1"]

Explanation

The correct answer is 1 mL. 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

- Divide the dose in mg by the concentration in mg/mL

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (176) / (2.2) = 80 kg

- (dose in mg) = (0.05) x (80) = 4 mg

- (volume in mL) = (4) / (4) = 1 mL

- (rounded volume in mL) = 1 mL

Therefore, the nurse should administer 1 mL of lorazepam from the vial to the client.

Correct Answer is ["1200"]

Explanation

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

(units of heparin) = (mL/hour) x (hours) x (units per mL)

Substituting the given values, we get:

(units of heparin) = (25) x (12) x (20,000 / 500)

Simplifying, we get:

(units of heparin) = (25) x (12) x (40)

(units of heparin) = 1200

Therefore, the client should receive 1200 units of heparin in 12 hours.
