Correct Answer: C

Rationale: The priority nursing action after corrective surgery for hypertrophic pyloric stenosis (HPS) is to assess the IV site for infiltration. This is crucial as it ensures proper fluid administration and prevents complications such as phlebitis or infiltration-related tissue damage. Applying restraints (Choice A) would not be appropriate in this situation as it is not related to the immediate post-operative care of an infant with an IV infusion. Administering a mild sedative (Choice B) is not indicated as the primary concern post-surgery is monitoring the IV site and the infant's response to the surgery. Attaching the nasogastric tube to wall suction (Choice D) is not the priority at this time, as assessing the IV site takes precedence to prevent potential complications.

Correct Answer: B

Rationale: The most important nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention helps to maintain airway patency and improve breathing, which are crucial in managing bronchiolitis. Administering bronchodilators (Choice A) may be a part of the treatment plan but is not the most important intervention. Monitoring oxygen saturation (Choice C) is important but falls secondary to providing direct respiratory support. Encouraging fluid intake (Choice D) is also essential but does not address the immediate respiratory needs of the child with bronchiolitis.

Correct Answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

Correct Answer: C

Rationale: The most appropriate response for the nurse is to emphasize the importance of consistency in discipline when dealing with toddlers. Toddlers are at a stage where they are exploring boundaries and learning what behaviors are acceptable. By being consistent, parents can help reinforce these boundaries and teach appropriate behaviors effectively. Choices A, B, and D do not provide specific guidance on how to address the discipline issue effectively. While acknowledging the challenges of this age (Choice A) and empathizing with the parents (Choice D) are important, the key point in this scenario is to highlight the significance of consistency in discipline (Choice C).

Correct Answer: A

Rationale: The priority nursing action when a child with a suspected fracture is brought to the emergency department is to immobilize the affected limb. Immobilization helps prevent further injury until a fracture is confirmed or ruled out. Applying ice or elevating the limb can wait until after immobilization has been achieved. Checking the child's neurovascular status is important but is not the priority action in this situation.
