A patient with a renal calculi receives a prescription for an intravenous infusion of 0.9% Sodium chloride Injection, USP 1,000 mL to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["400 mL\/hour"]

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

(mL/hour) = (mL/minute) x 60

Substituting the given values, we get:

(mL/hour) = (1000 / 150) x 60

Simplifying, we get:

(mL/hour) = 6.667 x 60

(mL/Hour) = 400

Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.

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.

Correct Answer is ["333"]

Explanation

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.
