Correct Answer: B

Rationale: Point tenderness is the most reliable indicator of a possible fracture in a child. It is a localized tenderness experienced when pressure is applied to a specific area, suggesting a potential fracture. This tenderness is considered more specific to a fracture than other symptoms such as lack of spontaneous movement, bruising, or inability to bear weight. Lack of spontaneous movement and inability to bear weight can be present in various musculoskeletal injuries, while bruising may not always be immediate or specific to a fracture.

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: Placing the child in a semi-Fowler's position after eating is beneficial for reducing symptoms of gastroesophageal reflux. This position helps prevent gastric contents from flowing back into the esophagus. The supine position (choice A) may worsen reflux symptoms by allowing gravity to assist in reflux, leading to discomfort and regurgitation. Prone position (choice B) is not recommended after eating as it may cause discomfort and increase the risk of aspiration due to pressure on the stomach. Trendelenburg position (choice D), with the head lower than the rest of the body, is not indicated for managing GERD after eating and may not provide the desired benefits in this context.

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: B

Rationale: Cellulitis is characterized by warmth at the site of skin disruption, indicating an infection. The correct answer is choice B. Choice A, 'Red, raised hair follicles,' is more indicative of folliculitis rather than cellulitis. Choice C, 'Papules progressing to vesicles,' is more characteristic of conditions like chickenpox, not cellulitis. Choice D, 'Honey-colored exudate,' is typical of wound infections with bacteria like Staphylococcus aureus, not cellulitis.
