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 C
Explanation
Rationale:
A. "I don't think you understand the risks to your health.": This response is dismissive of the client’s autonomy and implies the nurse is questioning the client’s decision-making ability. It can create a defensive reaction rather than supporting informed consent.
B. "You should talk with your family about it first.": While family support can be helpful, the decision for surgery ultimately rests with the client. Suggesting family involvement at this point could undermine the client’s right to make an independent healthcare decision.
C. "I will notify your provider regarding this decision.": This response respects the client’s autonomy and ensures the healthcare team is promptly informed. It also facilitates further discussion between the provider and client about the decision, ensuring it is fully informed.
D. "Let me remind you of the benefits of the surgery.": While reviewing benefits can be part of informed consent, doing so after the client has expressed a clear decision not to proceed may be perceived as coercive rather than supportive.
Correct Answer is C
Explanation
Rationale:
A. Current fecal impaction: While fecal impaction requires treatment, it is not related to the safety or pharmacologic effects of conjugated estrogen therapy and does not constitute a contraindication.
B. Present report of abdominal pain: Abdominal pain requires evaluation, but it is nonspecific and not an absolute contraindication to conjugated estrogen unless related to certain underlying conditions like liver disease or cancer.
C. Thrombophlebitis: Estrogen increases the risk of thromboembolic events by promoting clot formation. A history or presence of thrombophlebitis makes estrogen therapy unsafe due to the elevated risk of worsening venous thromboembolism.
D. Diverticulitis: Diverticulitis is an inflammatory bowel condition that is not directly affected by estrogen therapy. It would not typically prohibit the use of conjugated estrogen unless complications or comorbidities present additional risks.
