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.

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: D

Rationale: Following a structured meal plan is essential for managing diabetes mellitus. It helps regulate blood glucose levels and ensures proper nutrition. Monitoring blood glucose levels daily is important, not just once a day, to maintain control. Administering insulin based on blood glucose levels is crucial but should be done as per the healthcare provider's instructions, not only when blood glucose is high. Recognizing signs of hypoglycemia is important, but it is equally vital to prevent hypoglycemia by adhering to a consistent meal plan and insulin regimen.

Correct Answer: A

Rationale: The correct answer is A: 'High fever and Koplik spots.' Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Choice B, rash on the trunk with pruritus, is more indicative of rubella. Choice C, nausea, vomiting, and abdominal cramps, are not specific to either rubeola or rubella. Choice D, characteristics of a cold followed by a rash, is not a typical presentation of rubeola or rubella.

Correct Answer: A

Rationale: The priority nursing action after a child has undergone tracheostomy surgery is to suction the tracheostomy tube. Suctioning is crucial to maintain a clear airway, remove secretions, and prevent potential airway obstruction, which is essential for the child's respiratory function. Changing the tracheostomy dressing, while important for wound care, does not take precedence over airway clearance. Monitoring respiratory status is vital but comes after ensuring airway patency. Ensuring tracheostomy ties are secure is significant for stabilizing the tube but is not as urgent as maintaining a patent airway through suctioning.
