1. 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?
- A. Assist in the passage of formula through the esophagus
- B. Identify the number of reflux episodes that are occurring
- C. Determine the time it takes for the stomach to empty its contents
- D. Monitor the pH within the stomach
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.

- 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.
3. What is the most common cause of acute gastroenteritis in children under 5 years?
- A. Salmonella
- B. Rotavirus

Correct answer: B
Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.
