A nurse is preparing to administer diazepam 2 mg twice daily via NG tube. Available is diazepam oral solution 5 mg/1 mL. How many mL should the nurse administer with each dose?
Correct answer
A
Rationale
The correct answer is A: 0.4 mL. To calculate the correct dose to administer, we first need to determine the total daily dose (2 mg twice daily = 4 mg total). Then, we use the concentration of the oral solution (5 mg/1 mL) to calculate how many mL is needed to deliver the total dose. In this case, 4 mg ├À 5 mg/mL = 0.8 mL per dose. Since the question asks for the amount per dose, we divide this by 2 to get 0.4 mL for each dose. Therefore, the nurse should administer 0.4 mL with each dose. Choices B, C, and D are incorrect because they do not accurately calculate the dose based on the provided information.
