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. When caring for an alert 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color, what should be included?

• A. Back blows, abdominal thrusts, transport
• B. Oxygen, avoiding agitation, transport
• C. Assisting ventilations, back blows, transport
• D. Chest thrusts, finger sweeps, transport

Correct answer: B

Rationale: The correct approach for a child with a mild airway obstruction, respiratory distress, and normal skin color includes providing oxygen to support breathing, avoiding agitation that could worsen the situation, and arranging for transport to a healthcare facility. Option A is incorrect because abdominal thrusts are not recommended in a mild airway obstruction scenario, and back blows are typically used for choking. Option C is incorrect because assisting ventilations may not be necessary in a child with a strong cough and normal skin color. Option D is incorrect because chest thrusts are not recommended for a mild airway obstruction, and finger sweeps are used for foreign body airway obstructions.

3. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted by an autosomal recessive gene.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.

4. What is the priority nursing intervention for a child with a diagnosis of acute lymphoblastic leukemia (ALL) receiving chemotherapy?

• A. Preventing infection
• B. Administering chemotherapy
• C. Providing nutritional support
• D. Monitoring fluid intake

Correct answer: A

Rationale: The correct answer is A: Preventing infection. When caring for a child with acute lymphoblastic leukemia (ALL) undergoing chemotherapy, the top priority is to prevent infection. Chemotherapy suppresses the immune system, making the child more susceptible to infections. By implementing infection control measures such as hand hygiene, aseptic techniques, and environmental cleanliness, the nurse can help protect the child from potentially life-threatening infections. Administering chemotherapy (choice B) is important but not the priority over preventing infection. Providing nutritional support (choice C) and monitoring fluid intake (choice D) are essential aspects of care but take a back seat to preventing infection in this scenario.

5. The parents of a child with asthma ask the nurse how they can help their child prevent asthma attacks. What should the nurse advise?

• A. Avoid exposure to allergens
• B. Encourage regular exercise
• C. Provide a high-protein diet
• D. Increase fluid intake

Correct answer: A

Rationale: The correct answer is to advise the parents to avoid exposure to allergens. Asthma attacks are often triggered by allergens such as dust mites, pollen, pet dander, and mold. By minimizing the child's exposure to these triggers, the likelihood of asthma attacks can be reduced. Encouraging regular exercise is beneficial for overall health but may not directly prevent asthma attacks. Providing a high-protein diet and increasing fluid intake are important for general well-being but do not specifically address asthma prevention.
