ATI Mental Health Practice A

Correct Answer: A

Rationale: Weight gain is a common side effect of olanzapine, an atypical antipsychotic. Olanzapine is known to cause metabolic changes that can lead to weight gain. Monitoring weight regularly is essential to detect and manage this side effect to prevent associated health risks such as diabetes and cardiovascular issues. Hypotension (choice B) is not a common side effect of olanzapine. Olanzapine is more likely to cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. Hair loss (choice C) and hyperthyroidism (choice D) are not typically associated with olanzapine use.

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.

Correct Answer: C

Rationale: The correct answer is dopamine. Dopamine dysregulation is a key factor in the development of schizophrenia. Excess dopamine activity in certain brain regions is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopaminergic medications that reduce dopamine levels are often used to manage these symptoms, further supporting the role of dopamine in schizophrenia. Serotonin (Choice A) is more commonly associated with mood regulation and is implicated in depression and anxiety disorders. Norepinephrine (Choice B) is involved in the body's 'fight or flight' response and is linked to conditions like anxiety and PTSD. Acetylcholine (Choice D) plays a role in muscle movement and memory but is not primarily implicated in schizophrenia.

Correct Answer: C

Rationale: Dry mouth is a common side effect associated with tricyclic antidepressants (TCAs). TCAs can cause anticholinergic side effects, such as dry mouth, due to their mechanism of action. Educating the patient about dry mouth can help them stay informed and manage this common side effect effectively during treatment. Hypertension (Choice A) is not a common side effect of TCAs. Diarrhea (Choice B) is more commonly associated with selective serotonin reuptake inhibitors (SSRIs) than with TCAs. Weight loss (Choice D) is not a common side effect of TCAs; in fact, TCAs are more likely to cause weight gain.

Correct Answer: B

Rationale: Patients prescribed fluoxetine should be educated that the medication may take several weeks to achieve its full therapeutic effect. This information helps manage patient expectations and ensures they do not discontinue the medication prematurely due to lack of immediate results. Taking the medication in the morning to avoid insomnia is not a specific requirement for fluoxetine. Consuming alcohol while taking fluoxetine is not safe and can lead to adverse effects. It is crucial to report any side effects to the healthcare provider promptly for timely management and adjustment of the treatment plan.
