A nurse is preparing to administer ondansetron 4 mg IM stat. The amount available is ondansetron for injection 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct answer
2
Rationale
To calculate the mL to administer, divide the desired dose (4 mg) by the concentration (2 mg/mL). 4 mg / 2 mg/mL = 2 mL. Therefore, the correct answer is 2 mL. Choice A (0 mL) is incorrect as some medication needs to be administered. Choices B-G are also incorrect as they do not align with the calculation of the desired dose divided by concentration.
