A nurse is caring for an older adult client diagnosed with a cerebrovascular accident and has right-sided paralysis and aphasia. The client's son tells the nurse it is his fault because he did not insist that his mother live with him. Which of the following responses should the nurse make?

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:

The client taking an overdose of the medication is unlikely to be the cause of the symptoms. Disulfiram (Antabuse) is a medication used to treat alcohol dependence by causing adverse effects when alcohol is consumed. However, an overdose would not result in severe nausea and vomiting as described.

Choice B rationale:

Experiencing common side effects of the medication is a possibility, but severe nausea and vomiting are not typical side effects of disulfiram. The medication's primary purpose is to induce unpleasant effects when alcohol is consumed, not to cause severe gastrointestinal symptoms.

Choice C rationale:

Demonstrating an allergic response to the medication could potentially cause various symptoms, but severe nausea and vomiting are not commonly associated with allergies to disulfiram. Allergic reactions often manifest as skin rashes, itching, and respiratory symptoms, which are not described in this scenario.

Choice D rationale:

The correct choice. Disulfiram works by inhibiting alcohol metabolism, leading to the accumulation of acetaldehyde, a toxic substance, when alcohol is consumed. This buildup of acetaldehyde results in unpleasant symptoms like severe nausea, vomiting, headache, and flushing. Since the client has recently started taking disulfiram and reports experiencing severe nausea and vomiting after discontinuing the medication, it is most likely that the client consumed alcohol while taking the medication, triggering the adverse reaction.
