An attending physician is managing a critically ill patient who has acutely lost decision-making capacity and requires an urgent, non-emergent surgical intervention. The patient's chart contains no advance directive, designated healthcare proxy, or record of a court-appointed legal guardian. The clinical social worker has managed to contact several individuals in the patient's life who are willing to participate in discussions.

During a routine appointment, a physician discusses advance care planning with a patient recently diagnosed with early-onset Alzheimer disease. As the condition progresses, the patient will predictably lose cognitive capacity. Arrange the following decision-making frameworks in the correct ethical and legal hierarchy that providers must follow, ordering from the highest priority (most respectful of autonomy) to the lowest priority (used as a last resort).

A 15-year-old boy presents to the orthopedic clinic with a 3-month history of progressively worsening deep pain in his right distal thigh. The pain is persistent, often awakens him at night, and is not relieved by over-the-counter analgesics. Physical examination reveals a palpable, tender, and firm mass over the anterior distal femur. There is no history of preceding trauma, and the patient is afebrile. Arrange the following steps in the most appropriate chronological sequence for the evaluation and definitive management of this patient's suspected primary bone sarcoma.

A 68-year-old woman is brought to the surgical intensive care unit following a severe motor vehicle collision. She is intubated, sedated, and lacks decision-making capacity. The trauma surgery team recommends an emergent exploratory laparotomy. The patient has no written advance directive and has not legally appointed a healthcare proxy. Several family members are present in the waiting room and express conflicting views on whether the surgery should be performed. To obtain legally valid informed consent, arrange the following family members in the standard statutory order of priority for surrogate decision-making, from highest priority (first) to lowest priority (last).

An otherwise healthy 65-year-old woman arrives at the emergency department with severe right wrist pain and visible deformity following a slip and fall onto her outstretched hand. She is alert, and her vital signs are within normal limits. Physical examination reveals a characteristic 'dinner-fork' deformity of the right wrist with moderate swelling. There are no open wounds. Radiographs demonstrate a dorsally displaced, extra-articular fracture of the distal radius. The treating physician decides to manage the fracture non-operatively. Arrange the following steps for the acute management of this patient's fracture in the correct chronological order.

A 35-year-old woman is brought to the emergency department after a high-velocity motor vehicle collision. Her primary trauma survey is intact, and she is hemodynamically stable.

Arrange the following steps in the optimal chronological order for the acute orthopedic management of this patient's condition.

A 59-year-old male is evaluated in the emergency department for a sudden onset of severe, tearing chest pain that radiates to his interscapular region. The symptoms began 30 minutes prior to arrival. His past medical history includes essential hypertension and tobacco use. On evaluation, he appears extremely uncomfortable and diaphoretic. His blood pressure is 220/115 mm Hg in the right upper extremity and 175/90 mm Hg in the left upper extremity. His heart rate is 114/min. Auscultation reveals a high-pitched, early diastolic decrescendo murmur heard best at the right second intercostal space.

Arrange the following next steps in the optimal chronological sequence for managing this patient's condition.

A 65-year-old male with a history of treated pulmonary tuberculosis is brought to the emergency department after coughing up copious amounts of bright red blood.

A $65$-year-old man is hospitalized for symptomatic anemia and is receiving a transfusion of packed red blood cells. Thirty minutes into the transfusion, he develops acute-onset chills, severe flank pain, and shortness of breath. His temperature is 39.2°C (102.5°F), blood pressure is 85/50 mm Hg, and pulse is 120/min. The nurse notes that the urine in his Foley catheter bag has suddenly turned dark red.

An unconscious adult patient in the intensive care unit is currently receiving mechanical ventilation following a complicated abdominal surgery performed a week ago. The nursing staff reports a sudden increase in the volume of thick, purulent pulmonary secretions. The patient's core body temperature has risen to 39.1°C (102.4°F), and ventilator settings have been adjusted due to worsening hypoxia. A bedside chest radiograph demonstrates a dense, new consolidation in the right middle lobe, leading to a presumptive diagnosis of ventilator-associated pneumonia (VAP).
