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. Surgical repair for patent ductus arteriosus (PDA) is done to prevent the complication of

• A. pulmonary infection
• B. right-to-left shunt of blood
• C. decreased workload on left side of the heart
• D. increased pulmonary vascular congestion

Correct answer: D

Rationale: The correct answer is D: increased pulmonary vascular congestion. Surgical repair of patent ductus arteriosus (PDA) aims to prevent the complications associated with increased pulmonary vascular congestion, such as pulmonary hypertension and heart failure. Choice A, pulmonary infection, is not a direct complication of PDA but can occur secondary to other conditions. Choice B, right-to-left shunt of blood, is a feature of some congenital heart defects but not a direct complication of PDA. Choice C, decreased workload on the left side of the heart, is not a primary reason for surgical repair of PDA, as the main concern is the impact on pulmonary circulation.

3. When evaluating a child with a diagnosis of attention-deficit/hyperactivity disorder (ADHD) for medication management, what is an important assessment for the nurse to perform?

• A. Assess the child's sleep patterns
• B. Assess the child's dietary intake
• C. Assess the child's academic performance
• D. Assess the child's behavior at home

Correct answer: B

Rationale: Assessing the child's dietary intake is crucial as certain foods and additives can affect ADHD symptoms. Ensuring a balanced diet can help manage symptoms and provide proper nutrition. Assessing sleep patterns (Choice A) is also important, but dietary intake is more directly linked to symptom management in ADHD. Academic performance (Choice C) and behavior at home (Choice D) may be affected by ADHD but are not as directly related to medication management as dietary intake.

4. Why might a healthcare provider question a health care provider's order for a tap water enema for a 6-month-old infant with suspected Hirschsprung disease?

• A. The result could lead to loss of necessary nutrients.
• B. It could cause a fluid and electrolyte imbalance.
• C. It could increase the fear of intrusive procedures.
• D. The result could cause shock from a sudden drop in temperature.

Correct answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas are unlikely to lead to loss of necessary nutrients. Choice C is incorrect as it does not directly relate to the physiological risk of tap water enemas. Choice D is incorrect as shock from a sudden drop in temperature is not a common concern with tap water enemas.

5. A nurse is teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about blood glucose monitoring. What should the nurse emphasize?

• A. Checking blood glucose levels before meals and at bedtime
• B. Using a lancet device to obtain blood samples
• C. Using urine test strips for monitoring
• D. Recognizing signs of hypoglycemia

Correct answer: A

Rationale: Checking blood glucose levels before meals and at bedtime is essential for managing type 1 diabetes mellitus. This timing helps in assessing the effectiveness of insulin therapy, making adjustments to insulin doses, and preventing hyperglycemia and hypoglycemia. Option B is incorrect because it focuses on the method of obtaining blood samples rather than the timing of monitoring. Option C is incorrect as urine test strips are not recommended for accurate blood glucose monitoring in type 1 diabetes. Option D, recognizing signs of hypoglycemia, is important but not the primary emphasis when teaching about blood glucose monitoring.
