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.). mL.
The Correct Answer is ["0.04 mL"]
Step 1 is to find out how many mcg are in 1 mL. This is done by dividing the total amount of mcg available (250 mcg) by the total volume in mL (1 mL). So, 250 mcg ÷ 1 mL = 250 mcg/mL. Step 2 is to find out how many mL are needed to get 10 mcg. This is done by dividing the required amount in mcg (10 mcg) by the concentration in mcg/mL (250 mcg/mL). So, 10 mcg ÷ 250 mcg/mL = 0.04 mL. So the correct answer is 0.04 mL.

Correct Answer is ["56"]
Explanation
Step 1 is to calculate the total volume to be infused in minutes. This is done by multiplying the total volume (2000 mL) by the drop factor (20 gtt/mL), and then dividing by the total time (12 hr × 60 min/hr). So, (2000 mL × 20 gtt/mL) ÷ (12 hr × 60 min/hr) = 55.56 gtt/min, which rounds to 56 gtt/min.
Correct Answer is ["0.71 mL"]
Explanation
Step 1 is to calculate the amount of medication per mL. This is done by dividing the total amount of medication (250 mg) by the concentration (350 mg/mL). So, 250 mg ÷ 350 mg/mL = 0.71 mL.
