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: A

Rationale: Exposure therapy is considered the most appropriate intervention for a patient with a phobia of flying. This therapeutic approach involves gradually exposing the individual to the feared stimulus, in this case, flying, in a controlled and supportive environment. By facing the fear in a structured manner, the patient can learn to manage their anxiety response and eventually reduce their phobia-related symptoms. While cognitive restructuring may help change negative thought patterns and medication management can alleviate symptoms, exposure therapy is specifically designed to address phobias through systematic desensitization, making it the most suitable intervention in this scenario. Psychoeducation aims to provide information and support but may not directly target the phobia itself.

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).

Correct Answer: A

Rationale: Positive symptoms in schizophrenia refer to excesses or distortions in normal behavior and include symptoms like hallucinations, delusions, and disorganized speech and behavior. Disorganized speech and behavior are considered positive symptoms because they represent an excess or distortion of normal functions. Negative symptoms involve deficits in normal behavior, cognitive symptoms affect thinking processes, and mood symptoms relate to emotional experiences. Therefore, in this scenario, the disorganized speech and behavior exhibited by the patient are classified as positive symptoms.

Correct Answer: C

Rationale: The correct answer is C: Decreased need for sleep. A decreased need for sleep is a hallmark symptom of a manic episode in bipolar disorder. During manic episodes, individuals may experience significantly reduced sleep without feeling tired, which can lead to increased energy levels, impulsivity, and other manic symptoms. Excessive sleeping (choice A) is more indicative of depression rather than mania. Low self-esteem (choice B) and anhedonia (choice D) are also more commonly associated with depressive episodes rather than manic episodes in bipolar disorder.
