A nurse is caring for a client who has severe manifestations of schizophrenia and is medicated PRN for agitation with haloperidol. The nurse should assess the client for which of the following adverse effects?

A. Identify the client's nutritional status.

Explanation:

Given the significant weight loss and the client's distorted belief about her body image (believing she is fat despite losing weight), it is crucial to assess the client's nutritional status first. Rapid weight loss and distorted body image are characteristic features of an eating disorder, such as anorexia nervosa. The nurse needs to determine the extent of malnutrition and potential medical complications related to inadequate nutrition. This assessment will guide the subsequent interventions.

Why the other choices are incorrect:

B. Provide a structured environment for the client.

While providing a structured environment can be important in managing eating disorders, such as anorexia nervosa, it is not the first priority. Understanding the client's nutritional status and medical condition takes precedence.

C. Plan a therapeutic diet for the client.

Planning a therapeutic diet may be part of the client's care plan, but without understanding the underlying nutritional status and potential eating disorder, creating a diet plan may not be effective or appropriate.

D. Request a mental health consult.

While a mental health consult is important for addressing the client's distorted body image and potential eating disorder, it should follow the assessment of nutritional status. The nutritional assessment provides critical information for both medical and psychological interventions.

A. A pretreatment electroencephalogram (EEG) will be done.

An EEG is not typically necessary when starting valproate for bipolar disorder. EEGs are more commonly used to assess brain activity in the context of epilepsy.

B. High serum sodium levels can cause toxic levels of valproate.

Sodium levels are not directly related to the toxic levels of valproate. The primary concern with valproate is its impact on liver function and potential for hepatotoxicity.

C. Liver function tests must be monitored.

Explanation: Valproate is an antiepileptic and mood-stabilizing medication commonly used to treat bipolar disorder. One of the potential side effects of valproate is hepatotoxicity (liver damage). Therefore, monitoring liver function tests (such as serum transaminases) is important to assess the medication's impact on the liver and to ensure the client's safety.

D. Thyroid function tests should be performed every 6 months.

While thyroid function tests might be important for some medications, monitoring thyroid function is not a primary consideration when using valproate. The main focus with valproate is on liver function monitoring.
