Question 1 of 5
A client is prescribed 8mg of ondansetron IV to manage the side effects of chemotherapy, specifically nausea and vomiting. When is the optimal time for the nurse to administer this medication?
Correct Answer: C
Rationale: The correct answer is C: 30 minutes prior to starting the chemotherapy. Administering ondansetron before chemotherapy allows the medication to reach therapeutic levels in the bloodstream, effectively preventing nausea and vomiting triggered by the chemotherapy. Ondansetron works best when given prophylactically, rather than reactively.
Choice A is incorrect as it is reactive rather than proactive.
Choice B is incorrect because administering it immediately after chemotherapy may not provide adequate time for the medication to take effect.
Choice D is incorrect as waiting for the client to request the medication may result in delayed relief.
