Question 1 of 5
A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 6 hours as needed. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth.)
Correct Answer: 5
Rationale:
To determine the mL per dose, first, calculate the total amount of medication in 24 hours: 25 mg * 4 doses = 100 mg.
Then, divide the total amount by the concentration of the elixir (12.5 mg/5 mL) to get the total mL needed per day: 100 mg / 12.5 mg/mL = 8 mL. Finally, divide the total mL by the number of doses per day (4) to get the mL per dose: 8 mL / 4 doses = 2 mL per dose.
Therefore, the correct answer is 5 mL per dose. Other choices are incorrect as they do not follow the correct calculation steps or yield different results.
