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 obtaining a health history from parents of a 4-month-old boy with congenital hypothyroidism, what would the nurse most likely assess?

• A. The child's growth is above normal for his age.
• B. The child is active and playful.
• C. The skin appears pink and healthy.
• D. It is difficult to keep the child awake.

Correct answer: D

Rationale: In congenital hypothyroidism, infants often experience lethargy and difficulty staying awake due to low thyroid hormone levels. Choice A is incorrect as hypothyroidism can lead to poor growth in infants. Choice B is incorrect because hypothyroidism can cause decreased activity levels and lethargy rather than being active and playful. Choice C is incorrect as hypothyroidism can result in dry skin and poor skin tone, not necessarily pink and healthy-looking skin.

3. What is an early sign of congestive heart failure that the nurse should recognize?

• A. tachypnea
• B. bradycardia
• C. inability to sweat
• D. increased urinary output

Correct answer: A

Rationale: Tachypnea is an early sign of congestive heart failure that nurses should recognize. Tachypnea refers to rapid breathing, which can be an indication of the body's attempt to compensate for decreased cardiac output in congestive heart failure. Bradycardia (choice B) is a slow heart rate and is not typically associated with congestive heart failure. Inability to sweat (choice C) and increased urinary output (choice D) are not specific early signs of congestive heart failure and are not typically recognized as such.

4. An infant who had cardiac surgery for a congenital defect is to be discharged. What should the nurse emphasize to the parents regarding administering the prescribed antibiotic?

• A. Give the antibiotic between feedings.
• B. Ensure that the antibiotic is administered as prescribed.
• C. Shake the bottle thoroughly before giving the antibiotic.
• D. Keep the antibiotic in the refrigerator after the bottle has been opened.

Correct answer: B

Rationale: The correct answer is B: 'Ensure that the antibiotic is administered as prescribed.' It is crucial for the parents to follow the prescribed antibiotic regimen to prevent infections and promote proper healing following cardiac surgery. Option A is incorrect because the timing of antibiotic administration may vary depending on the specific medication and instructions. Option C is not necessary and could potentially affect the antibiotic's effectiveness. Option D is not relevant to the administration of the antibiotic and does not ensure proper usage.

5. A child with a diagnosis of appendicitis is scheduled for surgery. What preoperative intervention is important for the nurse to perform?

• A. Administering antibiotics
• B. Maintaining strict NPO status
• C. Encouraging fluid intake
• D. Monitoring for signs of infection

Correct answer: B

Rationale: The correct preoperative intervention for a child with appendicitis scheduled for surgery is maintaining strict NPO (nothing by mouth) status. This is crucial to reduce the risk of aspiration during anesthesia induction and prevent potential complications during surgery. Administering antibiotics may be a part of the treatment plan but is not a preoperative intervention. Encouraging fluid intake is contraindicated preoperatively to avoid delays in surgery and complications related to anesthesia. Monitoring for signs of infection is important postoperatively to assess for any complications that may arise due to the surgical procedure.
