Answer to Question 1
ANS: B
Ondansetron side effects include postural hypotension, vertigo, and bradycardia, all of which increase the client's risk for injury. The nurse should assist the client when getting out of bed. Headache and fluid retention are not side effects of this drug.
Answer to Question 2
ANS: C
Superior vena cava syndrome is often a late-stage manifestation. After the client is stabilized and comfortable, the nurse should initiate a conversation about advance directives. Allopurinol is used for tumor lysis syndrome. Potassium levels are important in tumor lysis syndrome, in which cell destruction leads to large quantities of potassium being released into the bloodstream. Surgery is rarely done for superior vena cava syndrome.
