A 29-year-old male is brought to the ED after being involved in a motor vehicular collision when his car struck a bridge abutment. He is intoxicated, has GCS 13, and complains of abdominal pain. His BP was 80mmHg systolic by palpation on admission, but rapidly increased to 110/70 with the administration of IV flui His heart rate is 120/min. The chest x-ray shows loss of aortic knob, widening of mediastinum, no rib fracture, and no hemopneumothorax. Contrast angiography:

Correct Answer: D

Rationale: The correct answer is D because in this scenario, the patient presents with signs suspicious of aortic injury, indicated by the widened mediastinum on chest x-ray. However, the definitive test for aortic injury is a CT scan of the chest, which is more sensitive and specific than contrast angiography. If the CT scan is normal, it effectively rules out aortic injury, making further imaging with contrast angiography unnecessary. Performing angiography in this case would expose the patient to unnecessary risks without providing additional diagnostic value. Therefore, the correct approach is to first perform a CT scan of the chest, and if it is normal, no further imaging is required. Choice A is incorrect as contrast angiography is indicated in suspected aortic injury cases. Choice B is incorrect as performing contrast angiography after a CT scan would be redundant and expose the patient to unnecessary risks. Choice C is incorrect as the accuracy of contrast angiography in diagnosing aortic rupture is not as high as indicated in the

Correct Answer: D

Rationale: The correct answer is D: "Massage of the affected area." Massaging the affected area can help improve blood flow and promote circulation, aiding in the rewarming process for frostbite injuries. This helps prevent further tissue damage and supports healing. Explanation for other choices: A: "Application of dry heat" can actually worsen frostbite by causing additional tissue damage. B: "Debridement of hemorrhagic blisters" is not recommended as it can lead to infection and further complications. C: "Early amputation to prevent septic complications" is an extreme measure and not warranted in the initial treatment of frostbite injuries.

Correct Answer: C

Rationale: Rationale: Choice C is correct because avoiding excessive absences from work demonstrates reliability and dependability. By consistently showing up for work, the nursing assistant ensures continuity of care for patients and demonstrates commitment to her responsibilities. This behavior also allows her colleagues to rely on her presence and support. Summary: A: Showing an interest in others is important but does not directly demonstrate dependability. B: Performing tasks she does not know could jeopardize patient safety and is not a sign of dependability. D: Respecting individual beliefs is crucial in healthcare but does not directly relate to dependability in the context of work attendance.

Correct Answer: B

Rationale: The correct answer is B: Psychological abuse. Threatening harm to a resident to prevent disclosure is a form of psychological abuse as it inflicts emotional harm and instills fear. It does not involve direct physical harm (choice A), financial exploitation (choice C), or substance abuse (choice D). Psychological abuse includes threats, intimidation, isolation, and coercion to control or manipulate the victim's behavior or emotions, which aligns with the scenario described.

Correct Answer: C

Rationale: The correct answer is C: Other members of the care team. A nursing assistant should only share information about residents with other members of the care team involved in the care of the resident to ensure effective and coordinated care. Sharing information with anyone she chooses (A) violates the resident's privacy rights. Sharing information with the resident's family and friends (B) may not always be appropriate or authorized. Not sharing information with anyone (D) could impede the quality of care provided to the resident. Sharing information with other members of the care team promotes collaboration and ensures the best possible outcomes for the resident.
