An obstetric rapid response team is managing a 34-year-old G3P3 patient who developed massive, life-threatening hemorrhage shortly after the uncomplicated vaginal delivery of a 4.2-kg infant. The placenta delivered intact. Initial evaluation revealed severe uterine atony. Despite vigorous bimanual massage and the administration of intravenous oxytocin, intramuscular methylergonovine, intramuscular carboprost, and rectal misoprostol, the patient continues to experience profuse bleeding. Her current blood pressure is 82/45 mm Hg with a heart rate of 130/min. A massive transfusion protocol has been initiated.

During a comprehensive annual wellness exam, an asymptomatic postmenopausal patient discusses her current osteoporosis regimen. She has been strictly adherent to weekly oral alendronate for the past 5 years. She has remained physically active and reports no history of clinical fractures, bone pain, or loss of height. A dual-energy x-ray absorptiometry (DEXA) scan obtained prior to this visit reveals a femoral neck T-score of $-2.1$, indicating stability compared to her prior assessments. Her renal function and serum calcium levels are normal.

A 61-year-old male is currently in the medical intensive care unit undergoing treatment for a severe exacerbation of chronic obstructive pulmonary disease. He was placed on prophylactic subcutaneous unfractionated heparin upon admission. On day 6 of hospitalization, routine complete blood count reveals a platelet count of $85,000/\mu L$, a significant decline from his admission baseline of $210,000/\mu L$. Concurrently, he complains of new-onset right calf pain, and venous duplex ultrasonography confirms a new deep vein thrombosis.

A 72-year-old man develops massive abdominal distension on postoperative day 4 following a right total knee arthroplasty. He is currently receiving intravenous hydromorphone for pain control. He reports nausea and diffuse abdominal discomfort but denies severe sharp pain or vomiting. He is still passing flatus. His temperature is $37.2^{\circ}\text{C}$ ($99.0^{\circ}\text{F}$), blood pressure is $130/80\text{ mmHg}$, and heart rate is $88/\text{min}$. On physical examination, the abdomen is markedly distended and tympanitic, with high-pitched bowel sounds. There is no involuntary guarding or rebound tenderness. Laboratory studies show a serum sodium of $138\text{ mEq/L}$, potassium of $4.0\text{ mEq/L}$, and calcium of $9.2\text{ mg/dL}$. A CT scan of the abdomen and pelvis with intravenous contrast reveals massive dilation of the cecum, ascending colon, and transverse colon with a maximum cecal diameter of $11.0\text{ cm}$. There is no mechanical transition point, free intraperitoneal air, or bowel wall pneumatosis. Arrange the following procedural and management steps in the correct sequential order for this patient according to standard guidelines, assuming each preceding intervention fails to resolve the condition.

A 62-year-old female is hospitalized for an exacerbation of chronic obstructive pulmonary disease. She has been receiving subcutaneous unfractionated heparin for deep vein thrombosis prophylaxis. On hospital day 6, her right leg becomes acutely swollen and painful. Venous duplex ultrasonography reveals a new popliteal vein thrombosis.

Arrange the following outpatient monitoring and treatment evaluation steps in the most appropriate chronological order.

An otherwise healthy $71$-year-old female is evaluated in the emergency department for severe unilateral head pain that began $3$ days ago. She notes exquisite tenderness when brushing her hair and describes an aching fatigue in her jaw muscles during meals.
