ATI Nursing Care of Children 2019 B

Correct Answer: A

Rationale: Polyarthritis is indeed frequently the initial sign of acute rheumatic fever in children. It presents as joint pain, swelling, and redness. Carditis (inflammation of the heart), Erythema marginatum (a skin rash), and Sydenham chorea (involuntary muscle movements) are typically seen in the later stages of acute rheumatic fever and not as the initial sign.

Correct Answer: C

Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.

Correct Answer: A

Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.

Correct Answer: B

Rationale: Continuous enteral feedings help stimulate the small intestine's adaptation in short bowel syndrome, promoting better nutrient absorption and eventually reducing reliance on TPN. This approach is crucial for long-term management and improving the child's prognosis. Choice A is incorrect because weaning off TPN typically occurs gradually over time, not the next day. Choice C is incorrect because TPN can be adjusted to provide necessary nutrients, and enteral feedings are mainly used to stimulate intestinal function. Choice D is incorrect as the addition of enteral feedings does not necessarily indicate imminent discharge; it primarily focuses on enhancing intestinal adaptation and reducing reliance on TPN.

Correct Answer: B

Rationale: Teaching infection control measures is crucial as Hepatitis A is highly contagious, especially in household settings. Proper hand hygiene and avoiding sharing personal items can prevent the spread of the virus within the family. Option A is incorrect because bed rest is not typically required for hepatitis A. Option C is incorrect as the child can return to school once feeling well and no longer contagious, not necessarily after a specific duration. Option D is incorrect because hepatitis A can be transmitted through contaminated food, water, or close personal contact.
