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 is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

3. When discussing the side effects of the Haemophilus influenzae (Hib) vaccine with parents, which sign should the nurse mention for an infant receiving the vaccine?

• A. Lethargy
• B. Urticaria
• C. Generalized rash
• D. Low-grade fever

Correct answer: D

Rationale: The correct answer is 'Low-grade fever.' A low-grade fever is a typical, mild side effect that can occur after the Hib vaccine is administered. It is a sign that the body's immune system is responding to the vaccine and is generally not a cause for concern. Lethargy, urticaria, and generalized rash are not commonly associated side effects of the Hib vaccine. Lethargy may be a sign of other issues, while urticaria and generalized rash are more indicative of allergic reactions rather than typical responses to the Hib vaccine.

4. A parent brings a 2-month-old infant with Down syndrome to the pediatric clinic for a physical and administration of immunizations. Which clinical finding should alert the nurse to perform a further assessment?

• A. Flat occiput
• B. Small, low-set ears
• C. Circumoral cyanosis
• D. Protruding furrowed tongue

Correct answer: C

Rationale: Circumoral cyanosis should alert the nurse to perform a further assessment because it may indicate inadequate oxygenation or circulation, potentially related to cardiac or respiratory issues. Flat occiput (choice A) is a common finding in infants and is not typically concerning. Small, low-set ears (choice B) are common in Down syndrome and not specifically indicative of an acute issue requiring immediate further assessment. Protruding furrowed tongue (choice D) is also commonly seen in infants with Down syndrome and typically does not warrant immediate further assessment unless associated with other concerning signs or symptoms.

5. The parents of a child who has just been diagnosed with type 1 diabetes ask about exercise. What should the nurse explain about exercise in type 1 diabetes?

• A. Exercise will increase blood glucose levels
• B. Exercise should be restricted
• C. Extra snacks are needed before exercise
• D. Extra insulin is required during exercise

Correct answer: C

Rationale: In type 1 diabetes, extra snacks are needed before exercise to prevent hypoglycemia. It is important to provide additional carbohydrates to maintain blood glucose levels during physical activity. Choices A, B, and D are incorrect. Exercise typically lowers blood glucose levels in individuals with diabetes; however, proper management and adjustments in insulin and food intake are necessary to prevent hypoglycemia. Exercise should not be restricted in individuals with type 1 diabetes but should be planned in coordination with healthcare providers to ensure safety and optimal glucose control. While some individuals may need adjustments in insulin dosages during exercise, the general statement that extra insulin is required during exercise in type 1 diabetes is not accurate.
