Answer to Question 1

B
A drug that causes disease-like symptoms is known to be iatrogenic. Nurses should be prepared for this possibility and be prepared to withdraw the drug if necessary and treat the symptoms. Such effects are not teratogenic. Patients with a genetic predisposition to respond differently to drugs are known to have idiosyncratic effects. Iatrogenic effects, even when known, are not typ-ically expected side effects.

Answer to Question 2

D
Varenicline can cause serious neuropsychiatric effects, including mood swings, depression, and self-injurious behavior. Because suicidality is a risk, patients experiencing these effects should contact their provider immediately. The symptoms are not common and are not likely to abate. It is not known if these symptoms indicate an underlying disorder or if the drug causes the symp-toms. Increasing the dose will increase the symptoms, since they are related to the drug.
