A patient with schizophrenia is prescribed risperidone. The nurse should monitor the patient for which common side effect of this medication?

Correct Answer: B

Rationale: When a patient is prescribed risperidone, an atypical antipsychotic, the nurse should monitor for weight gain as it is a common side effect of this medication. Weight gain can occur due to metabolic changes and increased appetite associated with risperidone use. Agranulocytosis is a severe decrease in a type of white blood cells, and it is not a common side effect of risperidone. Hair loss and hyperthyroidism are also not typically associated with risperidone use.

Correct Answer: B

Rationale: Patients prescribed lithium should maintain a consistent salt intake to prevent fluctuations in lithium levels. Salt intake can impact lithium levels, and sudden changes in salt intake can affect how the body absorbs and excretes lithium. Therefore, advising the patient to maintain a stable salt intake is crucial for the effectiveness and safety of lithium therapy. Choices A, C, and D are incorrect. Avoiding foods high in tyramine is more relevant for patients taking MAOIs, not lithium. Increasing protein intake or avoiding foods high in fat are not specific dietary recommendations for patients on lithium therapy.

Correct Answer: B

Rationale: Exposure and response prevention (ERP) is a specific type of CBT that is considered the most effective treatment for OCD. ERP involves exposing the individual to anxiety-provoking stimuli and preventing the usual compulsive responses, leading to a decreased anxiety response over time. This type of therapy helps individuals learn to tolerate the anxiety triggered by obsessions without engaging in compulsions, ultimately reducing OCD symptoms. Choices A, C, and D are incorrect. Dialectical behavior therapy (Choice A) is more commonly used for treating conditions like borderline personality disorder, not OCD. Interpersonal therapy (Choice C) focuses on improving interpersonal relationships and communication skills, which is not the primary approach for OCD. Supportive therapy (Choice D) provides emotional support and guidance but is not as effective as ERP in treating OCD.

Correct Answer: C

Rationale: The correct answer is C: Dry mouth. Dry mouth is a common side effect associated with tricyclic antidepressants (TCAs). TCAs block acetylcholine receptors, leading to anticholinergic effects such as dry mouth, constipation, blurred vision, and urinary retention. It is important for the nurse to educate the patient about this side effect to promote awareness and provide appropriate management strategies, such as maintaining good oral hygiene and staying hydrated. Choice A, hypertension, is not a common side effect of TCAs. Choice B, diarrhea, is not a typical side effect of TCAs; in fact, TCAs are more likely to cause constipation. Choice D, weight loss, is less common with TCAs as they are more likely to cause weight gain.

Correct Answer: C

Rationale: Methylphenidate is a central nervous system stimulant commonly used in the treatment of ADHD. It helps improve focus, attention, and impulse control in individuals with ADHD. Haloperidol and clozapine are antipsychotic medications typically used for other conditions such as schizophrenia, while fluoxetine is a selective serotonin reuptake inhibitor commonly used to treat depression and anxiety disorders. Therefore, the correct answer is Methylphenidate (Choice C).
