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 ["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
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.
