Correct Answer is []

Explanation

Rationale:

  • Potential Condition: The client with cirrhosis shows elevated ammonia (236 mcg/dL), confusion, agitation, and disorientation, which are classic findings of hepatic encephalopathy.
  • Actions to Take:
    • Lactulose is given to lower ammonia levels by promoting its excretion through the stool.
    • Assessing for asterixis (flapping tremor of the hands) is key in identifying worsening encephalopathy.
  • Parameters to Monitor:
    • Neurologic status (orientation, cognition, responsiveness) should be monitored closely to evaluate improvement or deterioration.
    • Safety measures are essential because confusion and agitation increase the client’s risk for falls and injury.

Correct Answer is ["A","B","D"]

Explanation

Rationale:

  • Hydration therapy is the cornerstone of pediatric diarrhea management, as children are at high risk for rapid fluid loss and dehydration. Both oral rehydration solutions and IV fluids may be necessary depending on severity.
  • Electrolyte replacement helps correct imbalances caused by frequent watery stools, especially sodium and potassium losses, preventing complications like hypovolemia and arrhythmias.
  • Clear liquid diet provides gentle reintroduction of fluids and easy-to-digest intake, helping to maintain hydration while minimizing gastrointestinal irritation.
  • Low-fiber diet may reduce stool bulk but is not a primary intervention for acute diarrhea.
  • Opioid analgesics are contraindicated in children with diarrhea due to risk of bowel obstruction and toxicity.
  • Antibiotic administration is only appropriate when a bacterial cause has been confirmed; most pediatric diarrhea is viral and self-limiting.
