The nurse is sitting with a client diagnosed with schizophrenia, who starts to laugh uncontrollably, although the nurse has not said anything funny. The nurse should say:

Choice A Reason
Monitoring for hypoglycemia at 1200 is not optimal because it is well past the peak action time of insulin aspart, which occurs approximately 45–90 minutes after administration. By noon, the insulin's effects are waning, and the risk of hypoglycemia is lower compared to the peak action period.

Choice B Reason
Monitoring at 1000 might still catch the tail end of the peak action time, but it is not the most likely time for hypoglycemia to occur. The nurse could miss the initial signs of hypoglycemia if monitoring starts two hours after administration.

Choice C Reason
0900 is the most appropriate time for the nurse to monitor for hypoglycemia. Insulin aspart has a rapid onset of action, peaking in about 45–90 minutes, and the effects last for 3–5 hours. Monitoring one hour after administration aligns with the start of the peak action time, when hypoglycemia is most likely to occur.

Choice D Reason
Monitoring at 1100 is less ideal because it is nearing the end of the peak action period. While there is still a risk for hypoglycemia, the highest risk would have been earlier, closer to the peak action time.

Choice a reason:
Risperidone is an antipsychotic medication that can help manage both positive symptoms (such as delusions and hallucinations) and negative symptoms (such as apathy and social isolation) of schizophrenia. Monitoring both types of symptoms is essential to evaluate the overall effectiveness of the treatment. Positive symptoms are often more responsive to medication, while negative symptoms can be more challenging to treat and may require a comprehensive approach including psychosocial interventions.

Choice b reason:
Disorganized symptoms, which include disorganized speech and behavior, are another aspect of schizophrenia that can be impacted by risperidone. While these symptoms are not mentioned in the client's current presentation, they are still important to monitor as part of a comprehensive assessment of the client's condition.

Choice c reason:
Negative symptoms like apathy and social isolation can significantly impact a client's quality of life and functional abilities. Risperidone can help improve these symptoms, but they often require longer treatment duration and additional supportive therapies for significant improvement.

Choice d reason:
Positive symptoms such as delusions and hallucinations are critical targets for risperidone treatment. These symptoms can be distressing and disruptive, and their improvement is a key indicator of the medication's effectiveness. Monitoring the reduction or resolution of these symptoms is crucial for assessing the client's response to risperidone.
