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 ["38.1"]

Explanation

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

(Celsius) = (Fahrenheit - 32) x (5 / 9)

Substituting the given value, we get:

(Celsius) = (100.6 - 32) x (5 / 9)

Simplifying, we get:

(Celsius) = 68.6 x (5 / 9)

(Celsius) = 38.111

(rounded Celsius) = 38.1

Therefore, the nurse should document the oral temperature as 38.1 C in the medical record.

Correct Answer is ["1.2 mL"]

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 dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg

- Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL

- Multiply the volume in mL per administration by the number of administrations per day

- Round the result to the nearest tenth

Using these steps, we get:

- (weight in kg) = (132) / (2.2) = 60 kg

- (dose in mg per administration) = (1) x (60) = 60 mg

- (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL

- (volume in mL per day) = (0.6) x (2) = 1.2 mL

- (rounded volume in mL per day) = 1.2 mL

Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
