Children with severe traumatic brain injury (TBI) may experience autonomic dysfunction characterized by all the following EXCEPT

Correct Answer: D

Rationale: Autonomic dysfunction in TBI typically involves elevated temperature, heart rate, and respiratory rate due to dysregulation of the autonomic nervous system. Lowered blood pressure is less common and may indicate hypovolemia or other conditions rather than autonomic dysfunction.

Correct Answer: B

Rationale: Stage III indicates local spread (e.g., to lymph nodes or peritoneum) but still carries a very good prognosis with appropriate treatment.

Correct Answer: C

Rationale: In children with hemophilia, the most common site for bleeding is at the ends of the long bones, such as the joints (especially the knees, elbows, and ankles). This is due to the joints being more prone to injury and stress during physical activities. As a result, spontaneous bleeding or bleeding following minor trauma can occur at these sites. Internal bleeding in the cerebrum or intestines is less common in children with hemophilia compared to bleeding in the joints.

Correct Answer: D

Rationale: Hypothyroidism is not a typical risk factor for obstructive sleep apnea.

Correct Answer: A

Rationale: Nosocomial pneumonia occurs in a healthcare setting. It is a type of pneumonia that is contracted during a hospital stay or other healthcare facilities. The risk of developing nosocomial pneumonia is higher in patients who are already hospitalized due to various medical conditions, surgeries, or use of medical devices like ventilators. The infection can be caused by different types of bacteria, viruses, or fungi present in the healthcare environment. Preventive measures, such as proper hand hygiene, infection control practices, and minimizing the use of invasive devices, are crucial in reducing the incidence of nosocomial pneumonia.
