A nurse on a mental health unit is admitting a client.
Exhibits
Select the 3 client findings the nurse should recognize as manifestations of water intoxication.
Activity level
White blood cell count
Sodium level
Potassium level
Hallucinations
Correct Answer : A,C,E
A. Activity level: Restlessness, pacing, and inability to remain seated are early neurological manifestations of water intoxication, stemming from cerebral edema related to hyponatremia. These signs often precede more severe symptoms like seizures.
B. White blood cell count: A count of 9,100/mm³ is within normal limits and does not indicate water intoxication. This value is unrelated to the dilutional effects of excessive fluid intake.
C. Sodium level: A sodium of 130 mEq/L indicates hyponatremia, which is a hallmark laboratory finding in water intoxication due to dilutional effects from excess fluid intake. Low sodium can cause neurological changes and altered mental status.
D. Potassium level: A potassium of 3.6 mEq/L is within the normal range and does not support a diagnosis of water intoxication. Potassium is less affected by acute overhydration compared to sodium.
E. Hallucinations: Responding to unseen stimuli can occur when hyponatremia causes cerebral swelling, disrupting normal brain function. In clients with psychotic disorders, excess water intake can exacerbate hallucinations or make them more pronounced.

Correct Answer is B
Explanation
A. Teach the client relaxation techniques: Teaching coping strategies is helpful but does not address the immediate need to understand the client’s perception of the crisis. It should follow assessment.
B. Confirm the client's perception of the event: The first step in crisis intervention is to assess and understand the client’s view of the situation. Clarifying perception allows the nurse to accurately prioritize interventions and provide appropriate support.
C. Notify the client's support person: Contacting support is beneficial for ongoing assistance but should occur after assessing the client’s understanding and emotional state.
D. Help the client identify personal strengths: Identifying strengths promotes coping and resilience, but it is a secondary intervention that should follow assessment and clarification of the client’s perception.
Correct Answer is B
Explanation
Rationale:
A. "I will use an interpreter when providing client teaching.": An interpreter is useful for clients with language barriers. Expressive aphasia affects speech production, not comprehension, so an interpreter would not address the main communication challenge.
B. "I will use a communication board to assess the client's needs.": A communication board allows the client to point to words, pictures, or symbols to express thoughts and needs without relying on verbal speech. This is an effective method for facilitating communication with expressive aphasia.
C. "I will provide written instructions for the client in 8-point font.": Written instructions can help if reading skills are intact, but 8-point font is too small for easy readability, especially for clients who may also have vision changes. Larger, clear print is recommended.
D. "I will use indirect lighting in the client's room.": Lighting preferences may improve comfort, but they do not address the core communication difficulty caused by expressive aphasia. This intervention is unrelated to improving the client-nurse communication.
