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 healthcare professional is teaching a class of new parents about how to position their infants during the first few weeks of life. Which position is safest?

• A. On the back, lying flat
• B. On either side, lying flat
• C. Head slightly elevated on the left side
• D. Head slightly elevated on the right side

Correct answer: A

Rationale: The correct answer is 'On the back, lying flat.' Placing infants on their back to sleep is recommended to reduce the risk of sudden infant death syndrome (SIDS). This position promotes safe sleep practices and helps prevent accidental suffocation. Choices B, C, and D are incorrect as placing infants on their side or with the head slightly elevated may increase the risk of breathing difficulties or other hazards during sleep.

3. When picked up by a parent or the nurse, an 8-month-old infant screams and seems to be in pain. After observing this behavior, what should the nurse discuss with the parent?

• A. Accidents and the importance of preventing them
• B. Limiting the infant's playtime with other children in the family
• C. Any other behaviors that the parent may have noticed
• D. Nutrition and specific vitamins recommended for infants

Correct answer: C

Rationale: Discussing any other observed behaviors with the parent is important to identify patterns or potential issues that could be affecting the infant's well-being. By exploring additional behaviors, the nurse can gather more information to assess the infant comprehensively. This approach allows for a more holistic understanding of the infant's health status, rather than focusing solely on the observed behavior of screaming and apparent pain. Options A, B, and D are incorrect as they do not directly address the need to explore other behaviors that may provide insights into the infant's condition and well-being.

4. A 6-month-old infant is diagnosed with cystic fibrosis. What explanation should the nurse provide to the parents about this condition?

• A. It is a condition affecting the respiratory and digestive systems.
• B. It is an autoimmune disorder affecting multiple organs.
• C. It is a genetic disorder that can be managed with medication.
• D. It is a condition caused by prenatal exposure to toxins.

Correct answer: A

Rationale: The correct answer is A: 'It is a condition affecting the respiratory and digestive systems.' Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It is caused by a defective gene that leads to the production of thick and sticky mucus in these organs. This mucus can clog airways in the lungs and block the ducts in the pancreas, affecting digestion. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder; it is a genetic condition. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but merely managing it with medication oversimplifies the comprehensive care needed for individuals with cystic fibrosis. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but is a genetic condition inherited from parents.

5. The nurse is implementing care for a school-age child admitted to the pediatric intensive care unit with diabetic ketoacidosis (DKA). Which prescribed intervention should the nurse implement first?

• A. Begin 0.9% saline solution intravenously as prescribed
• B. Administer regular insulin intravenously as prescribed
• C. Place the child on a cardiac monitor
• D. Place the child on a pulse oximetry monitor

Correct answer: A

Rationale: The correct first intervention when managing a child with diabetic ketoacidosis is to begin intravenous saline solution to address dehydration and restore electrolyte balance. Rehydration is essential to improve perfusion and correct electrolyte imbalances. Administering insulin without addressing dehydration can potentially lead to further complications. Placing the child on a cardiac monitor or pulse oximetry monitor is important but not the initial priority in managing DKA.
