Correct Answer: A

Rationale: The correct answer is A: Reduce proteinuria. In nephrotic syndrome, the primary treatment goal is to reduce proteinuria to prevent further kidney damage. Lowering blood pressure (choice B) is important in managing some types of kidney disease but is not the primary treatment goal in nephrotic syndrome. Increasing urine output (choice C) and preventing infections (choice D) are important aspects of supportive care but are not the primary treatment goal for nephrotic syndrome.

Correct Answer: A

Rationale: Infants with short bowel syndrome requiring prolonged total parenteral nutrition (TPN) are susceptible to central venous catheter infections, electrolyte losses, and hyperglycemia. Monitoring for these complications is crucial to prevent serious outcomes. Choices B, C, and D are incorrect because they do not reflect the common complications associated with prolonged TPN in infants.

Correct Answer: B

Rationale: The correct answer is B: Wheezing. Wheezing is a key distinguishing feature of bronchiolitis in infants, typically caused by respiratory syncytial virus (RSV) infection. Bronchiolitis is characterized by inflammation and mucus buildup in the small airways of the lungs, leading to wheezing sounds during breathing. Choices A, C, and D are incorrect because dry cough, stridor, and productive cough are not typical features of bronchiolitis in infants.

Correct Answer: B

Rationale: The correct answer is B: Stress management may be helpful. Stress is known to exacerbate symptoms of irritable bowel syndrome (IBS), making stress management an essential part of managing the condition. While dietary modifications can also be beneficial, a low-fiber diet is not universally recommended for IBS, as fiber can be important for some individuals. Milk products may or may not be contributing factors, as food triggers can vary among individuals. Pantoprazole, a proton pump inhibitor, is not typically the first-line treatment for IBS, as it is more commonly used for conditions like gastroesophageal reflux disease.

Correct Answer: C

Rationale: Prolonged jaundice is a classic sign of congenital hypothyroidism in newborns. In congenital hypothyroidism, the thyroid gland does not produce enough thyroid hormones, leading to symptoms like jaundice, poor feeding, constipation, and lethargy. While jaundice itself is a common condition in newborns, the term 'prolonged jaundice' specifically points towards the underlying thyroid issue. Hypothermia and excessive crying are not typically associated with congenital hypothyroidism.
