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"]
Step 1 is to determine the amount of medication in 1 mL. This is calculated by dividing the total available medication (250 mcg) by the total volume (1 mL):
250 mcg ÷ 1 mL = 250 mcg/mL
Step 2 is to determine how many mL are needed to obtain 10 mcg. This is done by dividing the required dose (10 mcg) by the concentration (250 mcg/mL):
10 mcg ÷ 250 mcg/mL = 0.04 mL
Thus, the correct amount to administer is 0.04 mL.

Correct Answer is ["150"]
Explanation
Step 1 is to determine the rate of infusion. This is done by dividing the total volume by the total time. So, we have 1200 mL ÷ 8 hr = 150 mL/hr.
So, the correct answer is 150 mL/hr.
Correct Answer is ["0.4"]
Explanation
The prescribed dosage of enoxaparin is 40 mg. The available medication is in a concentration of 100 mg/mL. So, the volume to administer is 40 mg ÷ 100 mg/mL = 0.4 mL. Rounding to the nearest tenth, the nurse should administer 0.4 mL.
So, the correct answer is 0.4 mL.
