1. What is the primary symptom of congenital diaphragmatic hernia in a newborn?

Correct answer: C

Rationale: Absent breath sounds on the affected side are a primary symptom of congenital diaphragmatic hernia. Cyanosis, bradycardia, and tachypnea may also be present but are not the primary symptom. Cyanosis is a bluish discoloration of the skin due to poor oxygenation, bradycardia is a slower than normal heart rate, and tachypnea is rapid breathing.

2. A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?

Correct answer: B

Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.

3. 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?

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.

4. Why are neonates predisposed to problems with thermoregulation?

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

5. A child is admitted for minimal change nephrotic syndrome (MCNS). The nurse recognizes that the child’s prognosis is related to what factor?

Correct answer: D

Rationale: The prognosis for children with MCNS is closely related to their response to steroid therapy. A favorable response to steroids usually indicates a better prognosis, while poor response may require alternative treatments and can indicate a more complicated disease course.
