1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

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 with a diagnosis of nephrotic syndrome is under the care of a nurse. What is the priority nursing intervention?

Correct answer: B

Rationale: The priority nursing intervention when caring for a child with nephrotic syndrome is to monitor urine output. This is essential to assess kidney function and evaluate the effectiveness of treatment. Administering diuretics (Choice A) may be a part of the treatment plan but should not be the priority over monitoring urine output. Administering corticosteroids (Choice C) is a common treatment for nephrotic syndrome, but monitoring urine output takes precedence. Restricting fluid intake (Choice D) may be necessary in some cases, but it is not the priority intervention compared to monitoring urine output.

3. A 6-year-old child comes to the school nurse reporting a sore throat, and the nurse verifies that the child has a fever and a red, inflamed throat. When a parent of the child arrives at school to take the child home, the nurse urges the parent to seek treatment. The nurse is aware that the causative agent may be beta-hemolytic streptococcus, and the illness may progress to inflamed joints and an infection in the heart. What illness is of most concern to the nurse?

Correct answer: D

Rationale: The correct answer is D, Rheumatic fever. Rheumatic fever can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. It is characterized by inflamed joints and can lead to serious complications such as heart infections. Tetanus (choice A) is caused by a bacterial toxin affecting the nervous system, Influenza (choice B) is a viral respiratory illness, and Scarlet fever (choice C) is also caused by streptococcus but is characterized by a sandpaper-like rash and strawberry tongue. However, in the scenario described, the nurse is most concerned about the child developing rheumatic fever due to the potential serious consequences associated with it.

4. Congenital heart defects have traditionally been divided into acyanotic or cyanotic defects. Based on the nurse’s knowledge of congenital heart defects, this system in clinical practice is

Correct answer: D

Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.

5. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.
