Nursing Elites

1. Which heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?

• A. S1 and S2
• B. S3 and S4
• C. Murmur
• D. Physiologic splitting

Correct answer: C

Rationale: A murmur is produced by turbulent blood flow within the heart or major arteries, resulting in audible vibrations.

2. A 2-year-old child has a chronic history of constipation and is brought to the clinic for evaluation. What should the therapeutic plan initially include?

• A. Bowel cleansing
• B. Dietary modification
• C. Structured toilet training
• D. Behavior modification

Correct answer: B

Rationale: Dietary modification is often the first step in managing chronic constipation in children, focusing on increasing fiber and fluid intake. Other interventions like bowel cleansing and toilet training may follow if dietary changes are insufficient.

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. 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.

5. The nurse is talking to a group of parents of school-age children at an after-school program about childhood health problems. Which statement should the nurse include in the teaching?

• A. Childhood obesity is the most common nutritional problem among children
• B. Immunization rates are the same among children of different races and ethnicity
• C. Dental caries is not a problem commonly seen in children since the introduction of fluoridated water
• D. Mental health problems are typically not seen in school-age children but may be diagnosed in adolescents

Correct answer: A

Rationale: Childhood obesity is the most common nutritional problem in children, with significant implications for long-term health, including the risk of developing chronic diseases.
