Nursing Elites

1. 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.

2. A 13-year-old boy comes to the school nurse complaining of sudden and severe scrotal pain. He denies any trauma to the scrotum. What is the most appropriate nursing action?

• A. Refer him for immediate medical evaluation
• B. Administer analgesics and recommend scrotal support.
• C. Apply an ice bag and observe for increasing pain.
• D. Reassure the adolescent that occasional pain is common with the changes of puberty.

Correct answer: A

Rationale: Sudden and severe scrotal pain in an adolescent male is a medical emergency and may indicate testicular torsion, which requires immediate evaluation and intervention to prevent testicular loss.

3. A 7-year-old has been diagnosed with cystic fibrosis. Chest physiotherapy has been ordered. What information should the nurse give to the parents regarding when chest physiotherapy is done?

• A. Before aerosol treatment
• B. After suctioning
• C. Before postural drainage
• D. Before meals

Correct answer: D

Rationale: The correct answer is D: 'Before meals'. Chest physiotherapy should be performed before meals to reduce the risk of vomiting and to ensure that the airways are clear for effective nutrition. Choices A, B, and C are incorrect because chest physiotherapy is ideally done before meals to optimize its benefits and avoid complications associated with timing.

4. A health care provider prescribes feedings of 1 to 2 oz Pedialyte every 3 hours and to advance to 1/2 strength Similac with iron as tolerated postoperatively for an infant who had a pyloromyotomy. The nurse should decide to advance the feeding if which occurs?

• A. The infant's IV line has infiltrated.
• B. The infant has not voided since surgery.
• C. The infant's mother states the infant is tolerating the feeding okay.
• D. The infant is taking the Pedialyte without vomiting or distention.

Correct answer: D

Rationale: The decision to advance feedings after a pyloromyotomy is based on the infant's ability to tolerate the current feedings without vomiting or abdominal distention. Ensuring the infant can keep down Pedialyte is the key indicator for moving to the next stage of feeding. Choices A, B, and C are incorrect because they do not directly relate to the infant's ability to tolerate the feeding. An infiltrated IV line, lack of voiding, or the mother's statement do not provide direct information on the infant's tolerance to the feeding, unlike the absence of vomiting and distention.

5. What major complication is associated with a child with chronic renal failure?

• A. Hypokalemia
• B. Metabolic alkalosis
• C. Water and sodium retention
• D. Excessive excretion of blood urea nitrogen

Correct answer: C

Rationale: Water and sodium retention is a major complication in chronic renal failure, leading to hypertension and edema. Hypokalemia and metabolic alkalosis are less common, and while BUN levels rise, retention rather than excretion is problematic in chronic renal failure.
