As a nurse approaches the nurses' station, a client diagnosed with a delusional disorder raises his voice and says, "You're following me. What do you want?" To prevent escalating fear and anger, the nurse takes a nonthreatening posture and makes which response in a calm voice?

A. Monitoring the client for neuroleptic malignant syndrome for up to 2 months after initiating the drug. Neuroleptic malignant syndrome (NMS) is a rare but serious adverse effect of antipsychotic medications. Monitoring for NMS, especially during the first few months of treatment, is crucial.

B. Encouraging the client to report signs of diabetes, such as increased thirst, hunger, and urination. Some antipsychotics, particularly second-generation antipsychotics, are associated with an increased risk of metabolic syndrome, including diabetes. Clients should be educated to report symptoms suggestive of hyperglycemia.

C. Advising the client to report weight gain and skin rashes to the health care provider immediately. Weight gain is a common side effect, particularly with second-generation antipsychotics. Skin rashes could indicate an allergic reaction, including serious conditions like Stevens-Johnson syndrome, requiring immediate medical attention.

D. Using the Abnormal Involuntary Movement Scale (AIMS) to assess for neurologic adverse effects. The AIMS scale is used to assess for tardive dyskinesia and other extrapyramidal symptoms, which are potential adverse effects of antipsychotic medications.

E. Administering the medication subcutaneously when the client is unable to swallow effectively. Antipsychotic medications are generally not administered subcutaneously. If a client cannot swallow, an alternative route such as intramuscular injection or an orally disintegrating tablet might be used.

A. Increasing forgetfulness and confusion: These symptoms are more characteristic of Alzheimer's disease or other types of dementia, not Parkinson's disease. While cognitive decline can occur in later stages of PD, it is not typically an initial symptom.

B. Tremors and muscle rigidity: Tremors (often starting in one hand) and muscle rigidity are hallmark initial symptoms of Parkinson's disease. These motor symptoms are among the most common early manifestations.

C. Visual disturbances and muscle weakness: Visual disturbances are not typically associated with early Parkinson's disease, and muscle weakness is not an initial symptom but could occur later due to rigidity and bradykinesia.

D. Fatigue and respiratory difficulties: While fatigue can occur, respiratory difficulties are not typically initial symptoms of Parkinson's disease and are more associated with later stages or other conditions.
