A nurse on a mental health unit observes a diagnosed schizophrenic patient on antipsychotics having an impaired gait and uncontrollable tremors. The nurse should recognize that which of the following adverse effects may be occurring?

The correct answer is choice C. Pseudoparkinsonism.

Choice A rationale:

Tardive dyskinesia is a long-term side effect of antipsychotic medications characterized by repetitive, involuntary movements, often around the mouth, such as lip-smacking, tongue protrusion, and chewing movements. It does not typically present with impaired gait and tremors.

Choice B rationale:

Acute dystonia involves sudden, severe muscle contractions, often affecting the neck, face, and back. Symptoms include twisting movements and abnormal postures, but it does not usually cause impaired gait and tremors.

Choice C rationale:

Pseudoparkinsonism is an adverse effect of antipsychotic medications that mimics the symptoms of Parkinson’s disease, including bradykinesia (slowness of movement), rigidity, tremors, and postural instability. The impaired gait and uncontrollable tremors observed by the nurse are characteristic signs of pseudoparkinsonism.

Choice D rationale:

Neuroleptic malignant syndrome is a rare but life-threatening reaction to antipsychotic medications. It presents with symptoms such as high fever, muscle rigidity, altered mental status, and autonomic dysfunction (e.g., unstable blood pressure, sweating). It does not typically present with impaired gait and tremors.

Choice A rationale:

Tachycardia (rapid heart rate) is a potential physical symptom of alcohol withdrawal. When alcohol-dependent individuals suddenly stop or reduce their alcohol intake, it can lead to increased sympathetic nervous system activity, resulting in elevated heart rate.

Choice B rationale:

Tremors (shakes) are common during alcohol withdrawal due to the suppression of the central nervous system by alcohol. Abrupt cessation of alcohol can lead to overactivity in the nervous system, resulting in tremors.

Choice C rationale:

Hallucinations can occur during alcohol withdrawal and are usually visual or tactile in nature. These hallucinations are often referred to as alcoholic hallucinosis and can be distressing for the individual experiencing them.

Choice E rationale:

Seizures can be a severe consequence of alcohol withdrawal. Known as alcohol withdrawal seizures, these episodes can occur within the first 48 hours after cessation of heavy alcohol consumption and are attributed to the hyperexcitability of the central nervous system.

Choice D rationale:

Hypotension (low blood pressure) is not typically associated with alcohol withdrawal. In fact, alcohol withdrawal often leads to an increase in blood pressure and heart rate due to the hyperactivity of the sympathetic nervous system.
