What is the primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux?
Prevent reflux.
Reduce gastric acid production.
Prevent hematemesis.
Increase gastric acid production.
The Correct Answer is B
The correct answer is choice B. Reduce gastric acid production.
Choice A rationale:
Preventing reflux is not the primary purpose of prescribing a histamine receptor antagonist. Histamine receptor antagonists work by reducing gastric acid production, which in turn can help alleviate symptoms of gastroesophageal reflux disease (GERD). They do not directly prevent the physical reflux of stomach contents into the esophagus.
Choice B rationale:
The primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux is to reduce gastric acid production. Histamine stimulates acid secretion in the stomach, and these medications (e.g., ranitidine, famotidine) block histamine receptors on stomach cells, leading to decreased acid secretion. This helps reduce the acidity of stomach contents that could contribute to esophageal irritation in GERD.
Choice C rationale:
Preventing hematemesis (vomiting blood) is not a primary action of histamine receptor antagonists. While reducing gastric acid production might indirectly help prevent complications such as bleeding due to irritation and inflammation of the esophagus, it's not the main purpose of these medications.
Choice D rationale:
Increasing gastric acid production is the opposite of the intended effect of histamine receptor antagonists. These medications are specifically used to decrease gastric acid production and provide relief from conditions where excess acid is causing problems, such as GERD.

Correct Answer is C
Explanation
The correct answer is Choice C: Measure abdominal girth.
Choice A rationale:
Taking vital signs, including blood pressure, is important in assessing the overall health status of a child, but it might not provide specific information about a probable intussusception. Blood pressure is not typically affected in a way that directly relates to intussusception.
Choice B rationale:
Auscultating for bowel sounds is an important assessment technique in various gastrointestinal conditions, but it may not be the most appropriate immediate action when dealing with a probable intussusception. While bowel sounds might be diminished or absent in intussusception, the priority should be on assessing other signs and symptoms.
Choice C rationale:
Measuring abdominal girth is an essential nursing action when a child with a probable intussusception has a normal, brown stool. Intussusception is the telescoping of one segment of the intestine into another, often leading to bowel obstruction. Abdominal distension or girth measurement can provide valuable information about the progression of the condition and potential obstruction.
Choice D rationale:
Notifying the practitioner is an important step, but it might not be the most immediate action required. Assessing and monitoring the child's condition should be the initial response to gather more information before notifying the practitioner.
