A nurse is preparing to administer 0.9% sodium chloride 1,500 mL. IV to be infused over 12 hr. The nurse should set the IV pump to deliver how many ml/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["125"]

To calculate the infusion rate in mL/hr, you can use the following formula:

Infusion Rate (mL/hr) = Total Volume (mL) / Time (hr)

In this case, the total volume is 1,500 mL, and the time is 12 hours:

Infusion Rate (mL/hr) = 1,500 mL / 12 hr = 125 mL/hr

So, the nurse should set the IV pump to deliver 125 mL/hr.

Correct Answer is ["0.71"]

Explanation

To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.

The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.

The desired dose is 250 mg.

So, you can use the following formula:

Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)

Volume to administer (mL) = 250 mg / 350 mg/mL

Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)

Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.

Correct Answer is ["0.9"]

Explanation

Convert the client’s weight from pounds to kilograms:
- 1 kilogram (kg) = 2.2 pounds (lb)
- Weight in kg = 187 lb / 2.2 = 85 kg
Calculate the dose of fentanyl in micrograms (mcg):
- Dose = 0.5 mcg/kg × 85 kg = 42.5 mcg
Determine the volume of fentanyl to administer:
- Available concentration is 50 mcg/ml
- Volume (ml) = Dose (mcg) / Concentration (mcg/ml)
- Volume (ml) = 42.5 mcg / 50 mcg/ml = 0.85 ml
Round the answer to the nearest tenth:
- Rounded volume = 0.9 ml
