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 A
Explanation
The correct answer is Choice A: Surgical removal of the affected section of bowel.
Choice A rationale:
Surgical removal of the affected section of bowel is the primary therapeutic management for most children with Hirschsprung's disease. Hirschsprung's disease is a congenital condition where there is a lack of nerve cells in a segment of the colon, leading to obstruction and dilation of the bowel. Surgical resection of the affected segment and reconnection of healthy bowel portions is the standard treatment to alleviate the obstruction and restore normal bowel function.
Choice B rationale:
Daily enemas might be used in some cases to manage symptoms temporarily, but they are not the primary therapeutic management for Hirschsprung's disease. Surgery is the mainstay of treatment.
Choice C rationale:
Permanent colostomy might be considered if the affected portion of bowel is extensive and cannot be safely reconnected after resection, but it's not the primary option for most children with Hirschsprung's disease.
Choice D rationale:
A low-fiber diet is not a therapeutic management for Hirschsprung's disease. Surgical intervention is necessary to address the underlying cause of obstruction, and diet modifications alone wouldn't resolve the condition.
Correct Answer is D
Explanation
The correct answer is choice D. Give small amounts of favorite fluids frequently to prevent dehydration.
Choice A rationale:
Having the child wear heavy clothing to prevent chilling is not an appropriate nursing intervention for an infant with an elevated temperature. Infants are more susceptible to temperature regulation issues, and heavy clothing could exacerbate their discomfort and potentially raise their body temperature further.
Choice B rationale:
Giving tepid water baths to reduce fever is not recommended for fever management in infants. Tepid baths might cause discomfort and shivering, which could lead to increased heat production and potential elevation of body temperature.
Choice C rationale:
Encouraging food intake to maintain caloric needs is important, but it might not be well-tolerated by an infant with an elevated temperature and upper respiratory tract infection. Infants often have reduced appetite during illness.
Choice D rationale:
Giving small amounts of favorite fluids frequently to prevent dehydration is an appropriate nursing intervention. Fever and elevated temperature can lead to increased fluid loss through sweating and increased respiratory rate. Offering small, frequent fluid intake helps maintain hydration and prevent dehydration. Using favorite fluids can also encourage the child to drink more.
