Correct Answer is D

Explanation

Choice A rationale:
High serum sodium levels do not directly cause toxic levels of valproate.
Choice B rationale:
While regular health monitoring is important, specifically performing thyroid function tests every 6 months is not a standard requirement for valproate use.
Choice C rationale:
A pretreatment electroencephalogram (EEG) is not typically required before starting valproate.
Choice D rationale:
Liver function tests must be monitored as valproate can cause liver failure that may be fatal.

A. Assign a staff member to stay with the client at all times. B. Lock the doors to the unit and secure windows so they cannot be opened. C. Remove any objects from the client's environment that could be used for self-harm. D. Provide the client with plastic eating utensils for meals.

Correct Answer is A

Explanation

Choice A rationale:
Assigning a staff member to stay with the client at all times is the priority action when a client declines to make a safety contract. This is because the immediate safety of the client is the primary concern in such situations.
Choice B rationale:
Locking the doors to the unit and securing windows so they cannot be opened might be considered a safety measure, but it is not the priority. The focus should be on direct supervision to ensure safety.
Choice C rationale:
Removing any objects from the client’s environment that could be used for self-harm is important, but it is not the priority. The immediate safety of the client through constant supervision is the priority.
Choice D rationale:
Providing the client with plastic eating utensils for meals is a safety measure, but it is not the priority. The immediate safety of the client through constant supervision is the priority.
