Answer to Question 1

ANS: C
Patients receiving chemotherapy are prone to weight loss resulting from nausea and vomiting. As with any drug therapy, the safe dosage per weight parameters should be assessed daily to avoid potential overmedication when patients are losing significant weight. Antiemetics are not calculated according to body surface area. Antiemetics are not toxic in recommended dosages. Fluid overload is unrelated to antiemetic therapy.

Answer to Question 2

ANS: D
Benzodiazepines (e.g., diazepam, lorazepam, midazolam) are effective in reducing not only the frequency of nausea and vomiting but also the anxiety often associated with chemotherapy. Benzodiazepines do not affect the effectiveness of other drugs. Although distraction can be an effective intervention, using benzodiazepines is not a method to achieve this goal. Tolerance to benzodiazepines can develop quickly; they do not affect the development of tolerance to other drugs.
