Mr. Cоllins is а 59-yeаr-оld mаle with a histоry of vomiting blood. He has been in good health except for hypertension and “stomach problems”, including chronic indigestion and heartburn usually relieved with over-the-counter antacids. He reports a poor appetite and recent weight loss. Mr. Collins states that he has a very stressful job at times, and he jokes “I knew this job would give me an ulcer”. Mr. Collins reports that last evening the heartburn was particularly bad, but he experienced relief after taking his antacids. He awakened early today with nausea, bloody emesis, weakness, and dizziness. He also reports black tarry stools. His wife drove him to the emergency room where he was admitted with an upper gastro-intestinal bleed. He is alert and oriented X3, breathing is quiet and unlabored. Skin and mucous membranes are pale and dry. There is 90 mL of dark, concentrated urine in a bedside urinal. An endoscopy reveals esophageal metaplasia and numerous gastric and duodenal ulcers. A chest x-ray shows normal lung fields with myocardial hypertrophy. An electrocardiogram (ECG) shows sinus tachycardia with occasional Premature Ventricular Contractions (PVCs). Vital signs are: 36.9 C, 112, 30, 94/42, and 98% Oxygen saturation. The following laboratory values were assessed: Serum Electrolytes Na 130 mEq/L Cl 89 mEq/L K 6.2 mEq/L BUN 52 mg/dl Creatinine 2.4 mg/dl CO2 16 mmol/L Ca 7.6 mg/dL Mag 1.5 mEq/L Phosphorous 4.4 mg/dL Glucose 138 mg/dL Albumin 3.0 g/dL Lactic Acid 1.8 mEq/L Mr. Collins’ sacral ulcer is edematous and caused by which of the following?

Jоn Gibbs is а 28-yeаr-оld cоllege student who hаs been reportedly healthy with the exception of recent fatigue and low energy. School “has been stressful this year” but he says that he tries to exercise and eat as well as he can to stay healthy. Mr. Gibbs faints in class and falls, hitting his head on a desk on the way to the floor. 911 is called and emergency personnel arrive! Vital signs are 37.9 C, 112, 30, 200/104. The cardiac monitor displays an irregular cardiac rhythm with premature ventricular contractions (PVCs). A swollen, red area is noted on the back of his head from the fall. Mr. Gibbs is subsequently admitted to the hospital. You observe that he is alert, shaky with trembling hands, anxious, and weak. Skin is dry and mucous membranes are moist. He has bilateral edema of his feet and ankles. A chest x-ray reveals myocardial hypertrophy, and a computerized tomography (CT) scan of the head is negative. Serum Electrolytes are assessed. Na 152 mEq/L Cl 104 mEq/L K 6.4 mEq/L BUN 42 mg/dl Creat. 3.4 mg/dl CO2 23 mmol/L Ca 7.2 mg/dl Mag 3.7 mEq/L Phos 5.6 mg/dl Glucose 132 mg/dl Albumin 4.4 g/dl Lactic Acid 1.8 mEq/L Mr. Gibbs complains of feeling “shaky and trembling”. This could be related to which of the following?
