Correct Answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less space for swelling within the skull compared to adults, making them more prone to experiencing symptoms like nausea and vomiting. Altered mental status and changes in pupillary reaction can also occur in both children and adults following head trauma, but they are not specifically more common in children. Tachycardia and diaphoresis are generally signs of autonomic nervous system activation and may occur in both children and adults, but they are not typically more common in children compared to adults following head trauma.

Correct Answer: B

Rationale: Choanal atresia is a congenital condition that presents with a blockage in the nasal passages at the junction of the nasal cavity and the nasopharynx.
To assess and confirm the diagnosis of choanal atresia, the nurse should focus on assessing the nasopharynx.

Choices A, C, and D are incorrect as choanal atresia specifically involves a blockage in the nasal passages, not the rectum, intestinal tract, or laryngopharynx. By assessing the nasopharynx, the severity of the obstruction can be determined, aiding in planning appropriate interventions for the newborn.

Correct Answer: C

Rationale: The correct behavior that the nurse needs to prevent postoperatively is straining at stool. Straining at stool should be avoided as it can increase intrathoracic pressure, leading to stress on the surgical site. This stress can potentially compromise the surgical repair and increase the risk of complications. Crying, coughing, and unnecessary movement, although important to monitor postoperatively, do not directly impact the surgical site as significantly as straining at stool does.
Therefore, the focus should be on preventing straining at stool to ensure the best postoperative outcome for the child.

Correct Answer: C

Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints is not recommended during a seizure as it can lead to further harm. Administering oxygen may be necessary after the seizure to support oxygenation, but it is not the priority during the seizure itself. Inserting a plastic airway is also not indicated as the jaw is clamped, and the child should not have anything placed in the mouth during a seizure.
Therefore, the correct action is to ensure the child's safety by protecting them from self-injury, preventing harm from uncontrolled movements and potential falls.

Correct Answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, putting the child at a higher risk of developing infections. Early detection of signs of infection is crucial to prevent serious complications and initiate timely treatment. Providing nutritional support is important for overall health but is not the priority when the child is at risk of infection. Monitoring for signs of bleeding is essential, but infection surveillance takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of pain is important for comfort but is not the priority over infection prevention and management.
