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
