A nurse is reinforcing teaching with a parent of an infant who has a prescription for amoxicillin 100 mg PO every 8 hours. The available amoxicillin suspension is 200 mg/5 mL. The nurse should tell the parent to administer how many teaspoons per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
To calculate the required teaspoons (tsp) of amoxicillin suspension per dose, we need to use the following
formula:
tsp = (dose in mg) ÷ (concentration in mg/mL) ÷ 5 mL per tsp Substituting the given values in the formula, we get:
tsp = (100 mg) ÷ (200 mg/5 mL) ÷ 5 mL per tsp
tsp = 0.5 tsp

Correct Answer is ["0.5"]
Explanation
To calculate the volume to be administered, the nurse should first divide the prescribed dose (100 mg) by the concentration of the available medication (200 mg/5 mL): 100 mg / (200 mg/5 mL) = 2.5 mL. Since there are 5 mL in a teaspoon, the parent should administer 2.5 mL / 5 mL/teaspoon = 0.5 teaspoons per dose.
Correct Answer is ["0.9"]
Explanation
To find out how many mL of gentamicin the nurse should administer, we need to set up a proportion. If 40 mg of gentamicin is equivalent to 1 mL, then 36 mg of gentamicin is equivalent to x mL.
The proportion can be writen as 40/1 = 36/x. Solving for x, we get x = (36 * 1) / 40 = 0.9 mL.
The answer is rounded to the nearest tenth as instructed.
