Carbamazepine has a boxed warning for which adverse effect?
Agranulocytosis
Birth defects
Skin rash
Liver damage
The Correct Answer is A
A. Agranulocytosis: Carbamazepine carries a boxed warning for serious hematologic effects, including agranulocytosis and aplastic anemia. Agranulocytosis is a significant drop in white blood cell count, leading to a high risk of infection.
B. Birth defects: While carbamazepine is associated with birth defects when taken during pregnancy, the boxed warning specifically highlights the risk of severe blood disorders like agranulocytosis.
C. Skin rash: Carbamazepine can cause serious skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, but the boxed warning focuses more on the hematologic risks.
D. Liver damage: Although carbamazepine can cause liver damage, this is not the primary focus of the boxed warning, which emphasizes hematologic effects.

Correct Answer is B
Explanation
A. A client who has recently begun treatment with propranolol (Inderal) for the treatment of social phobia. Propranolol, a beta-blocker, does not have a significant risk for dependence or withdrawal symptoms. It is primarily used for physical symptoms of anxiety, such as tachycardia.
B. A woman who has been taking lorazepam (Ativan) for several months after witnessing a traumatic motor vehicle accident. Lorazepam is a benzodiazepine, which has a high potential for dependence and withdrawal, especially with long-term use. This client is the most at risk for these issues.
C. A man whose obsessive-compulsive disorder (OCD) is being treated long-term with paroxetine (Paxil). While discontinuation symptoms can occur with SSRIs like paroxetine, the risk of dependence is significantly lower than with benzodiazepines.
D. A client with generalized anxiety disorder who has responded well since beginning treatment with fluoxetine (Prozac) earlier in the year. Like paroxetine, fluoxetine is an SSRI, and while discontinuation symptoms may occur, the risk of dependence is low.
Correct Answer is B
Explanation
A. Diarrhea: Opiates typically cause constipation, not diarrhea. Diarrhea is not a common finding with opiate use.
B. Pinpoint-sized pupils: Opiates commonly cause miosis, or pinpoint pupils. This is a classic sign of opiate use and is important for assessment.
C. Weight gain: Opiate use is not typically associated with weight gain; in fact, it can sometimes lead to decreased appetite and weight loss.
D. Bulimia: Bulimia is an eating disorder characterized by binge eating and purging. It is not a typical effect of opiate use.
