Question 1 of 5
A nurse is preparing to administer meperidine 35 mg IM to a client every 6 hr PRN for pain. Available is meperidine injection 75 mg/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: 0.5
Rationale:
To calculate the mL of meperidine needed per dose, we divide the desired dose (35 mg) by the concentration of the medication (75 mg/mL).
35 mg รท 75 mg/mL = 0.4667 mL.
Rounded to the nearest tenth, the nurse should administer 0.5 mL per dose.
Choice A (0.3 mL) is incorrect as it is too low.
Choice B (0.7 mL) is incorrect as it is too high.
Choice C (1.0 mL) is incorrect as it is significantly higher than the calculated dose.
Choice D (0.4 mL) is incorrect as it is slightly lower than the calculated dose.
Choice E, F, and G are irrelevant as the correct answer is 0.5 mL.
