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. A child is being assessed by a nurse for suspected nephrotic syndrome. What clinical manifestation is the nurse likely to observe?

• A. Jaundice
• B. Edema
• C. Hypertension
• D. Polyuria

Correct answer: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased permeability of the glomerular filtration barrier, leading to protein loss in the urine (proteinuria). The decrease in serum protein levels results in a reduced oncotic pressure, leading to fluid shifting from the intravascular space into the interstitial spaces, causing edema. Jaundice (choice A) is not typically associated with nephrotic syndrome. Hypertension (choice C) is more commonly seen in conditions like nephritic syndrome. Polyuria (choice D) is excessive urination and is not a prominent feature of nephrotic syndrome.

4. An 8-year-old girl was diagnosed with a closed fracture of the radius at approximately 2 p.m. The fracture was reduced in the emergency department and her arm placed in a cast. At 11 p.m. her mother brings her back to the emergency department due to unrelenting pain that has not been relieved by the prescribed narcotics. Which action would be the priority?

• A. Notifying the doctor immediately
• B. Applying ice
• C. Elevating the arm
• D. Giving additional pain medication as ordered

Correct answer: A

Rationale: The correct action would be to notify the doctor immediately. Unrelenting pain despite medication can indicate compartment syndrome, which is a medical emergency requiring immediate attention. Applying ice, elevating the arm, or giving additional pain medication may not address the underlying cause of the unrelenting pain, which could be a sign of a serious complication like compartment syndrome. Prompt medical evaluation is crucial in this situation to prevent potential complications.

5. The healthcare professional is assessing a 4-year-old client. Which finding suggests to the healthcare professional this child may have a genetic disorder?

• A. Inquiry reveals the child had feeding problems.
• B. The child weighs 40 lb (18.2 kg) and is 40 in (101.6 cm) in height.
• C. The child has low-set ears with lobe creases.
• D. The child can hop on one foot but cannot skip.

Correct answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders and can indicate underlying chromosomal abnormalities. This physical characteristic is known to be a common sign in various syndromes like Down syndrome. Choices A, B, and D are not directly linked to genetic disorders. Feeding problems and specific weight/height measurements are more general indicators of growth and development, while the ability to hop on one foot but not skip is a developmental milestone assessment that does not specifically point towards a genetic disorder.
