Correct Answer: A

Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.

Correct Answer: C

Rationale: Avoiding gluten is not typically necessary for managing gastroesophageal reflux disease (GERD) in children. The correct dietary instruction for a 2-year-old with GERD would be to avoid high-fat foods. High-fat foods can relax the lower esophageal sphincter, leading to increased reflux symptoms. While spicy foods and dairy products may also trigger reflux in some individuals, the primary focus should be on avoiding high-fat foods due to their direct impact on the lower esophageal sphincter, which exacerbates GERD symptoms.

Correct Answer: A

Rationale: When caring for a child with cerebral palsy, skeletal traction is the least likely treatment intervention. Cerebral palsy primarily involves motor function impairments, and skeletal traction is not a typical intervention for this condition. Physical therapy is commonly used to improve movement and function, orthotics help with posture and mobility, and occupational therapy addresses activities of daily living. These interventions are more aligned with the needs of a child with cerebral palsy compared to skeletal traction, making it the least likely treatment option.

Correct Answer: B

Rationale: The priority nursing intervention for a 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are essential to treat the infection, prevent its spread, and avoid potential complications. Administering antipyretics (Choice A) may help reduce fever but does not address the underlying cause of pneumonia, which is bacterial in this case. Monitoring fluid intake (Choice C) is important to maintain hydration but does not directly treat the infection. Providing nutritional support (Choice D) is crucial for overall health, but the immediate priority is to address the bacterial infection with antibiotics to prevent further complications and promote recovery.
