Nursing Elites

1. In what condition should the nurse be alert for altered fluid requirements in children? (Select all that apply.)

• A. Oliguric renal failure
• B. Increased intracranial pressure
• C. Mechanical ventilation
• D. All above

Correct answer: D

Rationale: Conditions like oliguric renal failure, increased intracranial pressure, and mechanical ventilation significantly alter fluid requirements in children. These conditions either restrict fluid output or require careful fluid management to avoid worsening the condition.

2. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

• A. Isotonic dehydration
• B. Hypotonic dehydration
• C. Hypertonic dehydration
• D. Hyperosmotic dehydration

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

3. Which is usually the only symptom of pediculosis capitis (head lice)?

• A. Itching
• B. Vesicles
• C. Scalp rash
• D. Localized inflammatory response

Correct answer: A

Rationale: Itching is typically the primary and most common symptom of pediculosis capitis due to the lice bites on the scalp.

4. Which factor is most likely to cause a "brittle" diabetic state in a child with type 1 diabetes?

• A. Noncompliance with diet
• B. Insulin resistance
• C. Frequent infections
• D. Hypothyroidism

Correct answer: C

Rationale: Frequent infections can destabilize blood sugar levels, leading to a "brittle" diabetic state in children with type 1 diabetes. Infections increase metabolic demands and can result in significant blood glucose fluctuations, requiring careful monitoring and adjustment of insulin therapy. Noncompliance with diet may affect blood sugar control but is not the primary cause of a "brittle" state. Insulin resistance is more common in type 2 diabetes rather than type 1. Hypothyroidism can impact metabolism but is not directly linked to the development of a "brittle" diabetic state in type 1 diabetes.

5. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.
