A nurse in the emergency department is implementing a plan of care for an older adult client who is experiencing delirium tremens. Which of the following actions should the nurse take first?

The highest priority assessment in this situation is to determine if the client has psychotic thinking. Psychotic thinking can indicate a severe mental health condition that requires immediate attention and intervention. If the client is experiencing psychotic symptoms, they might be at risk of harming themselves or others. Identifying and addressing psychotic thinking is crucial to ensure the safety and well-being of the client and those around them.

B. Asking the client to identify the cause of the crisis.

While understanding the cause of the crisis is important for providing appropriate care, it is not the highest priority. Psychotic thinking or risk of harm takes precedence over understanding the cause.

C. Identifying the client's coping skills.

Coping skills are important for managing the crisis and promoting the client's well-being, but assessing for psychotic thinking and immediate safety concerns comes before evaluating coping skills.

D. Identifying the client's support systems.

Support systems are valuable for the client's overall recovery, but they are not as time-sensitive as assessing for psychotic thinking or imminent safety risks. Identifying support systems can come after addressing the immediate concerns.

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.
