Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left to right shunt

Correct answer: B

Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. What should the nurse do first for a 6-year-old with asthma showing a prolonged expiratory phase, wheezing, and 35% of personal best peak expiratory flow rate (PEFR)?

• A. Administer a prescribed bronchodilator.
• B. Encourage the child to cough and take deep breaths.
• C. Report the findings to the healthcare provider.
• D. Identify the triggers that precipitated this attack.

Correct answer: A

Rationale: Administering a bronchodilator is the priority action in managing an acute asthma exacerbation in a child. Bronchodilators help to relax the muscles around the airways, opening them up and improving breathing. This intervention aims to address the immediate breathing difficulty and should be done promptly to provide relief for the child. Encouraging coughing and deep breaths (choice B) may worsen the child's condition by further constricting the airways. Reporting findings to the healthcare provider (choice C) is important but not the immediate priority in this acute situation. Identifying triggers (choice D) is crucial for long-term asthma management but is not the first step when managing an acute exacerbation.

3. When caring for a 5-year-old child with a history of seizures who suddenly begins to have a tonic-clonic seizure, what should the nurse do first?

• A. Administer oxygen
• B. Insert an oral airway
• C. Turn the child to the side
• D. Start an IV line

Correct answer: C

Rationale: During a tonic-clonic seizure, the priority action is to turn the child to the side. This helps maintain an open airway and prevents aspiration of secretions or vomitus. It also helps in keeping the airway clear and promotes safety during the seizure episode. Administering oxygen, inserting an oral airway, and starting an IV line are important interventions but should follow the initial step of positioning the child to prevent airway obstruction.

4. The nurse is caring for a 2-year-old child who was admitted for dehydration due to gastroenteritis. The child is now receiving IV fluids and appears more alert. What is the best indicator that the child’s condition is improving?

• A. The child is more alert and playful
• B. The child’s urine output has increased
• C. The child’s vital signs are stable
• D. The child is tolerating small amounts of oral fluids

Correct answer: B

Rationale: Increased urine output is a reliable indicator that hydration status is improving. While alertness and playfulness are positive signs, increased urine output directly reflects improved hydration. Stable vital signs are important but may not directly indicate hydration status. Tolerating small amounts of oral fluids is a good sign but may not be as direct an indicator as increased urine output.

5. A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant’s vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?

• A. Irregular palpable pulse
• B. Hyperactive bowel sounds
• C. Underweight for age
• D. Crying without tears

Correct answer: D

Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications. Irregular palpable pulse (Choice A) could indicate a cardiovascular issue but is less immediately life-threatening in this context. Hyperactive bowel sounds (Choice B) are more indicative of gastrointestinal issues rather than a life-threatening complication. Underweight for age (Choice C) may be concerning for growth-related issues but does not directly indicate a life-threatening complication like dehydration does.
