The Correct Answer is ["2"]
Determine the desired dose.
The nurse needs to administer 40 mg of acetaminophen.
Calculate the available dose per 2.5 mL.
The available acetaminophen is 10 mg/2.5 mL.
Calculate the volume to be administered.
Volume = Desired dose (mg) / Concentration (mg/2.5 mL) = 40 mg / (10 mg/2.5 mL) = 40 mg x (2.5 mL/10 mg) = 10 mL
Convert mL to teaspoons.
1 teaspoon (tsp) is approximately equal to 5 mL.
Number of teaspoons = Volume (mL) / Volume per teaspoon (mL/tsp) = 10 mL / 5 mL/tsp = 2 tsp

Correct Answer is ["48"]
Explanation
The patient has a new prescription for:
16 units of regular insulin daily
32 units of NPH insulin subcutaneously at breakfast
To calculate the total number of units the nurse should prepare in the insulin syringe, we need to add the units of each type of insulin:
Total units = Regular insulin units + NPH insulin units Total units = 16 units + 32 units Total units = 48 units
Correct Answer is ["200"]
Explanation
Determine the total volume to be infused.
The nurse is preparing to administer 100 mL of ceftriaxone sodium in dextrose 5% in water.
Calculate the infusion rate in mL/hr.
The infusion time is 30 minutes, which is equivalent to 30/60 = 0.5 hours.
Infusion rate = Total volume / Infusion time = 100 mL / 0.5 hr = 200 mL/hr
