A patient with schizophrenia is prescribed clozapine. What should the nurse monitor for as the most serious potential adverse effect?

Choice A reason: Involuntary lip-smacking and facial grimacing are classic signs of tardive dyskinesia, not pseudoparkinsonism. These symptoms result from dopamine receptor supersensitivity in the nigrostriatal pathway after prolonged blockade and are often irreversible, unlike the symptoms associated with drug-induced parkinsonism.

Choice B reason: Acute muscle spasms, particularly those that result in abnormal posturing of the head or trunk, indicate acute dystonia. This is a rapid-onset extrapyramidal reaction that requires immediate intervention with anticholinergic medications like benztropine, whereas pseudoparkinsonism involves more generalized rigidity and slow movement patterns.

Choice C reason: The subjective and objective need to move, or the inability to remain seated, defines akathisia. While both are extrapyramidal symptoms caused by dopamine blockade, akathisia is a disorder of movement urgency, whereas pseudoparkinsonism mimics the motor deficits of idiopathic Parkinson’s disease.

Choice D reason: Pseudoparkinsonism is characterized by a constellation of symptoms including "lead-pipe" muscle stiffness, a shuffling gait with a narrowed base, and a mask-like facial expression. These symptoms are caused by the blockade of dopamine D2 receptors in the basal ganglia by antipsychotic medications.

Choice A reason: Initiating redundant diagnostic investigations for a patient diagnosed with somatic symptom disorder often exacerbates the pathology by reinforcing the client's preoccupation with physical illness. Repeated testing can lead to unnecessary medical trauma, increased healthcare costs, and the accidental discovery of incidentalomas, which further fuels health-related anxiety.

Choice B reason: The primary therapeutic objective in somatic symptom disorder is functional improvement rather than the total elimination of physical sensations. By focusing on symptom management and enhancing the quality of daily life, clinicians help patients develop coping mechanisms that reduce the disability associated with their perceived physical distress.

Choice C reason: While psychiatric consultation is often beneficial, an immediate referral without establishing a therapeutic alliance or explaining the rationale can feel like abandonment to the patient. Effective management typically involves a collaborative approach where the primary clinician maintains regular contact to provide a sense of security and validation.

Choice D reason: Simple reassurance that nothing is wrong is frequently perceived by the patient as a dismissal of their genuine suffering. Patients with this disorder experience real pain and discomfort; therefore, telling them they have nothing to worry about invalidates their subjective experience and often causes them to seek other providers.
