A 32-year-old woman was diagnosed with schizophrenia approximately 4 years ago. She has been stable on haloperidol for 1 year, following trials with several atypical antipsychotics. Two weeks ago, she began exhibiting mild pseudo-Parkinson's disease symptoms. Because she did not achieve symptom control on so many medications, the PMHNP is reluctant to discontinue the haloperidol and instead chooses to treat the side effect. Which class of medications is the most appropriate for treating these side effects?
Cholinesterase inhibitor
Histamine 1 antagonist
Alpha 1 adrenergic agonist
Muscarinic 1 agonist
The Correct Answer is D
Choice A reason: Cholinesterase inhibitors are primarily used in the treatment of Alzheimer’s disease and other dementias. They enhance cholinergic transmission but are not used to treat extrapyramidal symptoms (EPS) like pseudo-Parkinsonism.
Choice B reason: Histamine 1 antagonists are typically used for allergic reactions and sleep disorders. They do not address dopamine-related motor side effects caused by antipsychotics.
Choice C reason: Alpha 1 adrenergic agonists are used for hypotension and nasal congestion. They do not have a role in managing EPS or Parkinsonian symptoms.
Choice D reason: Muscarinic 1 agonists (or more accurately, anticholinergic agents targeting muscarinic receptors) are effective in treating EPS, including pseudo-Parkinsonism. Drugs like benztropine and trihexyphenidyl work by restoring the balance between dopamine and acetylcholine in the basal ganglia, alleviating motor symptoms induced by dopamine blockade from antipsychotics.

Correct Answer is C
Explanation
Choice A reason: This is an open-ended question that invites further discussion. It is exploratory, not summarizing.
Choice B reason: This is a reflective statement that validates the client’s insight and emotional experience. It is supportive but not a summary of the client’s narrative.
Choice C reason: This is a clear summarizing statement. It encapsulates the client’s motivations, experiences, and evolving understanding of alcohol’s impact. It reflects back the client’s narrative in a structured and comprehensive way.
Choice D reason: This is a brief reflection that captures part of the client’s experience. However, it lacks the depth and structure of a full summary.
Correct Answer is A
Explanation
Choice A reason: The client exhibits traits of both avoidant and dependent personality disorders. Avoidant personality disorder is marked by social inhibition, feelings of inadequacy, and hypersensitivity to criticism. Dependent personality disorder involves excessive reliance on others for decision-making and daily tasks. Her avoidance of social interaction, fear of rejection, and dependence on her husband and mother support this dual diagnosis.
Choice B reason: Borderline personality disorder involves emotional instability, impulsivity, and intense interpersonal relationships. The client does not display mood lability, self-harm, or unstable relationships typical of borderline personality disorder.
Choice C reason: Social anxiety disorder involves intense fear of social situations due to concerns about being judged or embarrassed. While the client has social avoidance, her pervasive dependence and submissiveness suggest a personality disorder rather than an anxiety disorder alone.
Choice D reason: Agoraphobia is the fear of being in situations where escape might be difficult or help unavailable. It typically involves avoidance of public places, not reliance on others for social tasks or submissiveness in relationships.
