A nurse is preparing to administer exenatide 10 mcg subcutaneous. Available is exenatide 250 mcg/mL. How many ml. should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.04"]
To calculate the volume of exenatide to administer, you can use the following formula:
Volume (mL) = (Desired Dose in mcg) / (Concentration in mcg/mL)
In this case, the desired dose is 10 mcg, and the concentration is 250 mcg/mL. Plugging these values into the formula:
Volume (mL) = 10 mcg / 250 mcg/mL = 0.04 mL
Rounded to the nearest hundredth, the nurse should administer approximately 0.04 mL of exenatide.

Correct Answer is ["1.2"]
Explanation
To calculate the mL of phenobarbital to administer per dose, you can use the following steps:
Convert the client's weight from pounds to kilograms. There are approximately 2.2 pounds in 1 kilogram.
Weight in kg = 165 lb / 2.2 lb/kg ≈ 75 kg
Calculate the total daily dose based on the client's weight and the prescribed dose per kilogram:
Total daily dose = 2 mg/kg/day × 75 kg ≈ 150 mg/day
Since the dose is divided into two equal doses per day, calculate the dose per dose:
Dose per dose = Total daily dose / 2 = 150 mg / 2 = 75 mg
Now, you need to find out how many mL of phenobarbital 65 mg/mL corresponds to a dose of 75 mg:
Volume (mL) = Dose (mg) / Concentration (mg/mL) = 75 mg / 65 mg/mL ≈ 1.1538 mL
Rounded to the nearest tenth, the nurse should administer approximately 1.2 mL of phenobarbital per dose.
Correct Answer is ["4.5"]
Explanation
To calculate the mL of ondansetron to administer, follow these 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 = 132 lb / 2.2 ≈ 60 kg
Determine the total dosage required based on the client's weight:
Total dosage = Client's weight in kg × Dosage (mg/kg) Total dosage = 60 kg × 0.15 mg/kg = 9 mg
Determine the mL to administer based on the available concentration:
Concentration (mg/mL) = 2 mg / 1 mL = 2 mg/mL
Calculate the mL to administer:
mL to administer = Total dosage (mg) / Concentration (mg/mL) mL to administer = 9 mg / 2 mg/mL = 4.5 mL
Round the answer to the nearest tenth:
The nurse should administer 4.5 mL of ondansetron.
