Answer to Question 1
A, B, C
Feedback:
Abrupt cessation of benzodiazepines may lead to a withdrawal syndrome characterized by nausea, headache, vertigo, malaise, and nightmares. Withdrawal symptoms may be caused by the abrupt separation of benzodiazepine molecules from their receptor sites and the resulting acute decrease in gamma-aminobutyric acid (GABA) neurotransmission. Because GABA is an inhibitory neurotransmitter, less GABA may produce a less inhibited central nervous system (CNS) and therefore symptoms of hyperarousal or CNS stimulation. The nurse would not categorize hypotension or bradycardia as indicating benzodiazepine withdrawal.
Answer to Question 2
A
Feedback:
There is a risk of decreasing normal levels of erythropoietin if epoetin alfa (Procrit), or any of this classification of drug (erythropoiesis-stimulating agents), is given to patients who have normal renal functioning and adequate levels of erythropoietin. The patient should be taught that the drug will only be prescribed if he develops anemia due to inadequate erythropoietin. Although it is true the doctor may prescribe the drug when it is appropriate, this answer does not explain why it is inappropriate to prescribe it now. Anemia alone is not sufficient cause for prescribing Procrit and not all chemotherapy results in anemia.
