Question 1 of 5
A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 4 hr as needed. The amount available is diphenhydramine elixir 125 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale:
To determine the mL per dose, divide the prescribed dose by the concentration of the medication. In this case, 25 mg รท 125 mg/5 mL = 1 mL.
Therefore, the correct answer is B. Option A (0.5 mL) is incorrect as it is half of the correct dosage. Options C, D, and the remaining choices are also incorrect as they do not align with the calculated dosage based on the medication concentration and prescribed dose.
