Nursing Elites

1. A 14-month-old child is admitted to the hospital with laryngotracheobronchitis (LTB). Which assessment findings should the nurse expect?

• A. Cyanosis and dyspnea
• B. Productive cough and high fever
• C. Barking cough and inspiratory stridor
• D. Pale laryngeal and dyspnea

Correct answer: C

Rationale: The correct answer is C: 'Barking cough and inspiratory stridor.' Classic signs of laryngotracheobronchitis (LTB) include a barking cough, often described as a seal-like cough, and inspiratory stridor, which is a high-pitched sound heard during inspiration. These symptoms occur due to inflammation and narrowing of the upper airway. Choices A, B, and D are incorrect as they do not align with the typical assessment findings of LTB. Cyanosis and dyspnea (Choice A) may occur in severe cases but are not specific to LTB. Productive cough and high fever (Choice B) are more indicative of lower respiratory tract infections. Pale laryngeal and dyspnea (Choice D) are not characteristic findings of LTB.

2. What is the most critical physiological 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 most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

3. A major reason for the development of respiratory distress syndrome in the preterm infant is:

• A. Excessive surfactant
• B. Lack of surfactant
• C. Immature immune system
• D. Lack of body fat

Correct answer: B

Rationale: The correct answer is B: Lack of surfactant. Respiratory distress syndrome (RDS) in preterm infants is primarily due to a lack of surfactant, which is crucial for keeping the lungs inflated. Without adequate surfactant, the alveoli collapse, leading to breathing difficulties. Choice A, Excessive surfactant, is incorrect as RDS is caused by an insufficient amount of surfactant. Choice C, Immature immune system, and Choice D, Lack of body fat, are not directly related to the development of respiratory distress syndrome in preterm infants.

4. The parents of a 2-year-old boy who had a repair of exstrophy of the bladder at birth ask when they can begin toilet training their son. The nurse replies based on what knowledge?

• A. Most boys in the United States can be toilet trained at age 3 years.
• B. Training can begin when he has sufficient bladder capacity.
• C. Additional surgery may be necessary to achieve continence.
• D. They should begin now because he will require additional time.

Correct answer: B

Rationale: Toilet training should begin when the child has sufficient bladder capacity and control, which may be delayed in children who have undergone surgical repairs for conditions like bladder exstrophy. Premature training can lead to frustration and setbacks.

5. What signs and symptoms are indicative of a urinary tract disorder in the infancy period (1-24 months)? (Select all that apply.)

• A. All below
• B. Poor feeding
• C. Hypothermia
• D. Frequent urination

Correct answer: A

Rationale: In infants, urinary tract disorders may present with poor feeding, hypothermia, and frequent urination. Pallor can be associated with other conditions but is less specific to urinary tract disorders.
