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 nurse is inspecting the skin of a child with atopic dermatitis. What would the nurse expect to observe?

• A. Erythematous papulovesicular rash
• B. Dry, red, scaly rash with lichenification
• C. Pustular vesicles with honey-colored exudates
• D. Hypopigmented oval scaly lesions

Correct answer: B

Rationale: In atopic dermatitis, the characteristic presentation includes a dry, red, scaly rash with lichenification. This appearance is due to chronic inflammation and scratching. Choice A is incorrect as erythematous papulovesicular rash is more indicative of conditions like contact dermatitis. Choice C is incorrect as pustular vesicles with honey-colored exudates are seen in impetigo. Choice D is incorrect as hypopigmented oval scaly lesions are more characteristic of tinea versicolor.

3. What is the nurse’s priority intervention when preparing for admission of a child with acute laryngotracheobronchitis?

• A. Pad the side rails of the crib.
• B. Arrange for a quiet, cool room.
• C. Place a tracheotomy set at the bedside.
• D. Obtain a recliner so that a parent can stay.

Correct answer: C

Rationale: The correct answer is to place a tracheotomy set at the bedside. Acute laryngotracheobronchitis can cause airway obstruction, which may require an emergency tracheotomy. Having the tracheotomy set readily available ensures quick access in case of respiratory distress. Padding the side rails of the crib, arranging for a quiet, cool room, and obtaining a recliner for a parent are important aspects of care but are not the priority when managing a potentially life-threatening airway emergency.

4. The nurse is admitting a newborn with hypospadias to the nursery. The nurse expects which finding in this newborn?

• A. Absence of a urethral opening is noted
• B. Penis appears shorter than usual for age
• C. The urethral opening is along the dorsal surface of the penis
• D. The urethral opening is along the ventral surface of the penis

Correct answer: D

Rationale: In hypospadias, the urethral opening is located along the ventral surface of the penis. This congenital condition results in the urethral meatus opening on the underside of the penis, rather than at the tip. Choice A is incorrect as there is typically a urethral opening present, though in an abnormal location. Choice B is not a characteristic feature of hypospadias. Choice C is incorrect as the urethral opening in hypospadias is not along the dorsal surface but rather along the ventral surface of the penis.

5. What behavior is essential for preventing in a child postoperatively after undergoing heart surgery to repair defects associated with tetralogy of Fallot?

• A. Crying
• B. Coughing
• C. Straining at stool
• D. Unnecessary movement

Correct answer: C

Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.
