Correct Answer: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased glomerular permeability leading to the loss of proteins, particularly albumin, in the urine. This results in decreased oncotic pressure, leading to fluid shifting into the interstitial spaces and causing edema. Jaundice (Choice A) is not a typical clinical manifestation of nephrotic syndrome. Hypertension (Choice C) is more commonly associated with conditions like glomerulonephritis. Polyuria (Choice D) is not a primary symptom of nephrotic syndrome; instead, patients may have reduced urine output due to fluid retention from edema.

Correct Answer: B

Rationale: The priority nursing intervention for a 7-year-old child with type 1 diabetes mellitus is monitoring blood glucose levels. This is crucial for managing and adjusting insulin therapy to maintain blood glucose within the target range. Administering insulin as prescribed is important but should be based on monitoring blood glucose levels. Teaching the child how to self-administer insulin may be appropriate for older children but may not be the priority for a 7-year-old. Encouraging regular exercise is a valuable aspect of diabetes management but is not the immediate priority over monitoring blood glucose levels.

Correct Answer: B

Rationale: For a child with nephrotic syndrome, it is crucial to avoid foods high in salt to manage symptoms and prevent complications. Excessive salt intake can lead to fluid retention and exacerbate edema, which are common issues in nephrotic syndrome. Encouraging a high-protein diet (Choice A) may put additional strain on the kidneys and worsen the condition. While protein restriction is sometimes needed, it is not the primary dietary concern in nephrotic syndrome. Similarly, a low-protein diet (Choice D) is not typically recommended as it may lead to malnutrition in children. Although a low-sodium diet (Choice C) may sound similar to avoiding foods high in salt, the emphasis should be on reducing salt intake specifically, rather than a generalized low-sodium approach.

Correct Answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.

Correct Answer: D

Rationale: When feeding a newborn with choanal atresia, the nurse can anticipate that the infant may take only part of the feeding before pausing for air. This is due to the fact that infants with choanal atresia struggle to breathe through their nose while feeding. Choice A is incorrect as choking typically involves a more severe airway obstruction. Choice B is incorrect because difficulty swallowing is not the primary concern in choanal atresia. Choice C is incorrect as the issue is not related to hunger cues but rather the physiological challenges associated with breathing while feeding.
