ATI Nursing Care of Children 2019 B

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: B

Rationale: The correct answer is to place the baby on their back to sleep. This position is the most effective way to prevent sudden infant death syndrome (SIDS) according to research and recommendations from healthcare providers. Choice A, using a firm mattress, is important for infant safety but not as directly related to preventing SIDS. Keeping the room warm, as mentioned in choice C, is not recommended as it may increase the risk of SIDS. While breastfeeding has many benefits, choice D, breastfeeding exclusively is not the most effective method for preventing SIDS.

Correct Answer: B

Rationale: "Currant jelly" stools, consisting of mucus and blood, are characteristic of intussusception in children. It occurs due to the telescoping of a segment of the intestine into an adjacent segment, leading to obstruction and subsequent mucosal ischemia, causing the passage of bloody mucus in the stool. Bilious vomiting can be seen in other conditions like bowel obstruction, abdominal distention can be present but is not as specific, and constipation is less likely in the presentation of intussusception.

Correct Answer: B

Rationale: Constipation is the most common cause of abdominal pain in school-aged children. It is often due to dietary factors such as low fiber intake or insufficient fluid consumption. Chronic constipation can lead to complications like fecal impaction and soiling, highlighting the importance of early recognition and treatment. Gastroenteritis, although common, typically presents with diarrhea and vomiting. Appendicitis is more common in adolescents and typically presents with right lower quadrant pain. Irritable bowel syndrome is less common in children and is characterized by recurrent abdominal pain associated with defecation.

Correct Answer: C

Rationale: Isolating the child is a priority to prevent the spread of infection until meningitis is confirmed or ruled out. Meningitis, particularly bacterial, is highly contagious and can lead to outbreaks if not properly managed. Isolation and prompt treatment are critical in preventing serious complications. Administering antibiotics immediately without confirmation of the diagnosis can be harmful if the cause is viral or non-infectious. Performing a lumbar puncture is a diagnostic procedure that should be done by a healthcare provider but is not the initial action when suspecting meningitis. Obtaining a complete blood count may be part of the diagnostic workup but is not the most appropriate initial action in suspected meningitis.
