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 teaching a class of new parents about positioning 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 A: '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 helps ensure the baby's airway remains clear and reduces the likelihood of suffocation. Choices B, C, and D are not as safe as placing the infant on their back, as they may increase the risk of accidental suffocation or SIDS.

3. A child is being assessed for suspected intussusception. What clinical manifestation is the nurse likely to observe?

• A. Projectile vomiting
• B. Currant jelly stools
• C. Abdominal distension
• D. Constipation

Correct answer: C

Rationale: The correct clinical manifestation that a nurse is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception is a medical emergency where a part of the intestine folds into itself, causing obstruction. Abdominal distension is a common symptom due to the obstruction and the build-up of gases and fluids. While currant jelly stools (Choice B) are a classic sign of intussusception, they are typically seen in later stages of the condition and may not be present during the initial assessment. Projectile vomiting (Choice A) is more commonly associated with conditions like pyloric stenosis. Constipation (Choice D) is not a typical manifestation of intussusception; the condition usually presents with severe colicky abdominal pain and possible passage of blood and mucus in stools.

4. The nurse is assessing a 9-year-old girl with a history of tuberculosis at age 6 years. She has been losing weight and has no appetite. The nurse suspects Addison disease based on which assessment findings?

• A. Arrested height and increased weight
• B. Thin, fragile skin and multiple bruises
• C. Hyperpigmentation and hypotension
• D. Blurred vision and enuresis

Correct answer: C

Rationale: In a child with suspected Addison disease, the presence of hyperpigmentation (bronzing of the skin) and hypotension are key clinical findings. Hyperpigmentation is due to increased ACTH stimulation, resulting in melanocyte stimulation. Hypotension occurs due to decreased aldosterone production and subsequent sodium loss. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease; thin, fragile skin and multiple bruises are more indicative of conditions like Cushing's syndrome; blurred vision and enuresis are not typically associated with Addison disease.

5. During an assessment, a nurse is examining the skin of a child with cellulitis. What would the nurse expect to find?

• A. Red, raised hair follicles
• B. Warmth at skin disruption site
• C. Papules progressing to vesicles
• D. Honey-colored exudate

Correct answer: B

Rationale: The correct answer is B: 'Warmth at skin disruption site.' Cellulitis is characterized by localized warmth at the site of skin disruption, which indicates an infection. Choice A, 'Red, raised hair follicles,' is more typical of folliculitis. Choice C, 'Papules progressing to vesicles,' is suggestive of conditions like herpes simplex virus infections. Choice D, 'Honey-colored exudate,' is associated with impetigo, not cellulitis. When assessing cellulitis, nurses should primarily look for warmth, erythema, edema, and tenderness at the affected site.
