Nursing Elites

1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

2. A child with a diagnosis of asthma is being cared for by a nurse. What is an important nursing intervention?

• A. Administering bronchodilators
• B. Encouraging physical activity
• C. Monitoring oxygen saturation
• D. Providing nutritional support

Correct answer: A

Rationale: Administering bronchodilators is a crucial nursing intervention for a child with asthma because it helps to open the airways and ease breathing during an asthma attack. Bronchodilators are medications that work by relaxing the muscles around the airways, making it easier for the child to breathe. Encouraging physical activity may exacerbate asthma symptoms in some cases due to increased respiratory effort and exposure to triggers. Monitoring oxygen saturation is important but does not address the immediate need of opening the airways during an asthma episode. Providing nutritional support is essential for overall health but is not the primary intervention needed in managing an acute asthma exacerbation.

3. A child is admitted with extensive burns. The nurse notes burns on the child’s lips and singed nasal hairs. The nurse should suspect that the child has a(n)

• A. chemical burn
• B. inhalation injury
• C. electrical burn
• D. hot-water scald

Correct answer: B

Rationale: Burns on the lips and singed nasal hairs indicate inhalation injury, suggesting the child has inhaled hot gases or smoke. This presentation is common in cases where the respiratory tract is exposed to hot gases or smoke, leading to potential airway compromise. Choice A, chemical burn, is incorrect because there is no mention of exposure to chemicals, and the symptoms described are more indicative of inhalation injury. Choice C, electrical burn, is incorrect as there is no evidence of electrical involvement in the scenario provided. Choice D, hot-water scald, is incorrect because the presence of singed nasal hairs points more towards inhalation injury than a scald from hot water, emphasizing the need to prioritize airway management and respiratory support.

4. An additional defect is associated with exstrophy of the bladder. For what anomaly should the nurse assess the infant?

• A. Imperforate anus
• B. Absence of one kidney
• C. Congenital heart disease
• D. Pubic bone malformation

Correct answer: D

Rationale: The correct answer is D: Pubic bone malformation. Exstrophy of the bladder is commonly associated with pubic bone malformation as the condition involves a defect in the pelvic region. Imperforate anus, absence of one kidney, and congenital heart disease are not typically associated with exstrophy of the bladder, making them incorrect choices. Therefore, the nurse should primarily assess the infant for pubic bone malformation in this case.

5. A 2-week-old infant is admitted with a tentative diagnosis of a ventricular septal defect. The parents report that their baby has had difficulty feeding since coming home after birth. What should the nurse consider before responding?

• A. Feeding problems are common in neonates.
• B. Inadequate sucking is not significant unless cyanosis is present.
• C. Ineffective sucking and swallowing may be early indications of a heart defect.
• D. Many neonates retain mucus, which can interfere with feeding for several weeks.

Correct answer: C

Rationale: Ineffective sucking and swallowing can be early signs of a heart defect like a ventricular septal defect. This is crucial information for the nurse to consider as it aligns with the infant's tentative diagnosis. Choice A is too general and does not provide specific relevance to the situation. Choice B is incorrect as inadequate sucking can indeed be significant, especially in the context of a potential heart defect. Choice D is not directly related to the potential heart defect and feeding difficulties mentioned in the scenario.
