A nurse is preparing to administer fentanyl 0.5 mcg/kg via IV bolus to a client who weighs 187 lb. Available is fentanyl 50 mcg/ml. How many mi should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.9"]

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

Correct Answer is ["150"]

Explanation

To calculate the IV pump rate, you need to divide the total volume (1,200 ml) by the total infusion time (8 hours). Here's the calculation:

IV Pump Rate (ml/hr) = Total Volume (ml) / Total Infusion Time (hr)

IV Pump Rate (ml/hr) = 1,200 ml / 8 hr

IV Pump Rate (ml/hr) = 150 ml/hr

So, the nurse should set the IV pump to deliver 150 ml/hr.

Correct Answer is ["3"]

Explanation

To calculate how many tablets of pyrazinamide the nurse should administer, you can use the following steps:

Convert the client's weight from pounds (lb) to kilograms (kg):
Client's weight in kg = Client's weight in lb / 2.2 Client's weight in kg = 165 lb / 2.2 ≈ 75 kg

Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 75 kg × 20 mg/kg = 1500 mg

Determine the number of tablets needed:
Number of tablets = Total dosage / Tablet strength Number of tablets = 1500 mg / 500 mg/tablet = 3 tablets

The nurse should administer 3 tablets of pyrazinamide
