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 ["300"]

Explanation

To calculate how many milligrams (mg) of guaifenesin the client is taking with each dose, you can use the following steps:
Determine the volume of the client's dose. The client is taking 1 tablespoon (Tbsp) of guaifenesin oral solution.
1 Tbsp is approximately equal to 15 mL.
Determine the concentration of guaifenesin in the oral solution, which is 100 mg/5 mL.
Calculate the amount of guaifenesin in the client's dose:
Amount (mg) = (Volume of dose in mL / Concentration in mg/mL)
Amount (mg) = (15 mL / 5 mg/mL) = 3 doses of 100 mg each
So, the client is taking 300 mg of guaifenesin with each dose.

Correct Answer is ["1.5"]

Explanation

To calculate the number of tablets to administer, you can use the following calculation:

Number of tablets = Desired dose (mg) / Tablet strength (mg per tablet)

Number of tablets = 15 mg / 10 mg per tablet

Number of tablets = 1.5 tablets
