A 33-year-old man is struck by a car at 56 km/h. His next priority should be to:

Correct Answer: D

Rationale: The correct answer is D because performing diagnostic peritoneal lavage or a FAST exam is crucial in evaluating for intra-abdominal injuries after blunt trauma. This will help determine if there is internal bleeding or organ damage requiring immediate intervention. A: Performing external fixation of the pelvis is not the immediate priority in this scenario as internal injuries need to be ruled out first. B: Obtaining abdominal and pelvic CT-scans may provide detailed information, but they are time-consuming and not the immediate priority for a potentially unstable patient. C: Performing arterial embolization of the pelvic vessel is not the initial priority as the patient's internal injuries need to be evaluated first.

Correct Answer: B

Rationale: The correct answer is B: Rewarm. The priority for a burn victim with a core temperature of 34°C is to rewarm the body to prevent hypothermia, which can worsen the patient's condition. Escharotomy is a surgical procedure to relieve pressure from burns, not related to temperature. Oxygen mask may be needed but warming is the immediate concern. IV narcotics are not indicated for hypothermia.

Correct Answer: B

Rationale: The correct answer is B: Tilt head and lift chin. This is the simplest and most effective way to open the airway in an unconscious patient. By tilting the head back and lifting the chin, the tongue is pulled away from the back of the throat, preventing obstruction and allowing for easier breathing. This maneuver helps to maintain a clear airway and facilitates better airflow to the lungs. Other choices are incorrect because: A: "Pull out the tongue" can be dangerous and may cause further obstruction. C: Lifting the neck from behind does not directly address airway obstruction. D: Jaw thrust is a technique used for patients with suspected spinal injuries, not the simplest method for airway management in an unconscious patient.

Correct Answer: D

Rationale: The correct answer is D: Control of hemorrhage. Managing hemorrhage is essential to prevent shock and ensure adequate perfusion to the affected limb. This step is crucial in stabilizing the patient's condition before addressing other priorities. A: Reduction of pain, while important, is not the primary concern in the acute phase of a long bone fracture. B: Prevention of infection is important, but not the immediate priority. C: Prevention of further soft tissue injury is also crucial, but controlling hemorrhage takes precedence to prevent life-threatening complications.

Correct Answer: D

Rationale: The correct answer is D because residents with dementia tend to have longer stays in long-term care facilities due to the progressive nature of the condition and the need for ongoing specialized care. Residents admitted for terminal care (choice A) typically have shorter stays as they are in the final stages of life. Residents admitted for rehabilitation or temporary illness (choice B) stay for a shorter duration as they receive treatment and recover. Residents who are developmentally disabled (choice C) may have varying lengths of stay but typically not as long as those with dementia due to different care needs. In summary, the correct answer is D because dementia requires long-term care, while the other choices involve shorter stays for different reasons.
