Nursing Elites

1. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.

2. What is the most critical physiologic change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.

3. The parent of a child hospitalized with acute glomerulonephritis asks the nurse why blood pressure readings are being taken so often. What knowledge should influence the nurse's reply?

• A. The antibiotic therapy contributes to labile blood pressure values.
• B. Hypotension leading to sudden shock can develop at any time.
• C. Acute hypertension is a concern that requires monitoring.
• D. Blood pressure fluctuations indicate that the condition has become chronic.

Correct answer: C

Rationale: Acute hypertension is a common complication of acute glomerulonephritis, requiring frequent monitoring to prevent complications such as encephalopathy or heart failure. Blood pressure fluctuations can occur but are not necessarily indicative of chronic disease.

4. A child with acute gastrointestinal bleeding is admitted to the hospital. The nurse observes which sign or symptom as an early manifestation of shock?

• A. Restlessness
• B. Rapid capillary refill
• C. Increased temperature
• D. Increased blood pressure

Correct answer: A

Rationale: Restlessness is an early sign of shock due to decreased perfusion and oxygenation to the brain. This symptom requires immediate attention to prevent the progression to more severe stages of shock. Rapid capillary refill (Choice B) is not typically an early sign of shock but rather a sign of adequate perfusion. Increased temperature (Choice C) may occur in later stages of shock due to the body's response to stress. Increased blood pressure (Choice D) is not an early sign of shock; in fact, blood pressure tends to decrease in shock as a compensatory mechanism.

5. An infant is born with a gastroschisis. Care preoperatively should include which priority intervention?

• A. Prone position
• B. Sterile water feedings
• C. Monitoring serum laboratory electrolytes
• D. Covering the defect with a sterile bowel bag

Correct answer: D

Rationale: The correct priority intervention for an infant with gastroschisis is to cover the exposed abdominal contents with a sterile bowel bag. This action helps protect the intestines from injury, contamination, and dehydration before surgical repair. Choice A, placing the infant in the prone position, is not appropriate as it does not address the immediate need to protect the exposed intestines. Choice B, sterile water feedings, and Choice C, monitoring serum laboratory electrolytes, are not the priority interventions for this condition. Sterile water feedings may not provide the necessary protection for the exposed intestines, and monitoring electrolytes, while important, is secondary to the immediate need for protection and hydration of the exposed abdominal contents.
