(Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["17"]

The correct answer is 17 mL/hour. To find the answer, we can use the following formula:

(mL/hour) = (units/hour) x (mL per unit)

Substituting the given values, we get:

(mL/hour) = (1,400) x (250 / 20,000)

Simplifying, we get:

(mL/hour) = (1,400) x (0.0125)

(mL/hour) = 17.5

(rounded mL/hour) = 17

Therefore, the nurse should program the infusion pump to deliver 17 mL/hour of heparin in dextrose 5% in water.

Correct Answer is ["20"]

Explanation

The correct answer is 20 mg. 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

- Round the result to the nearest whole number

Using these steps, we get:

- (weight in kg) = (178) / (2.2) = 80.909 kg

- (dose in mg) = (0.25) x (80.909) = 20.227 mg

- (rounded dose in mg) = 20 mg

Therefore, the nurse should administer 20 mg of IV diltiazem to the client.

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.
