The fоllоwing 8 questiоns refers to the scenаrio for Bаrbаra Ewing Barbara Ewing is an 86-year-old female with a recent history of poor appetite, difficulty swallowing, and weight loss. Her medical history includes hypertension and coronary artery disease managed by medications and a stroke several years ago leaving her with left sided weakness and inability to walk.

Ms. Ewing typically sits in a wheelchair most of the day, however lately she has felt too weak and has been staying in bed most of the time. Skin breakdown has developed on her coccyx and elbows with notable erythema, edema, warmth, tenderness, and yellow drainage. Ms. Ewing has not been able to rate her coccygeal pain using a pain scale, however she moans, cries, and pushes you away when her coccyx is touched. Otherwise, Ms. Ewing has intact, dry skin and mucous membranes, pitting edema of both legs and feet, and scant urine output. Vital signs are: 38.7, 112, 26, 96/44. The following laboratory values were assessed: Serum Electrolytes Na 155 mEq/L Cl 106 mEq/L K 2.9 mEq/L BUN 18 mg/dL Creatinine 1.1 mg/dL CO2 19 mmol/L Ca 7.9 mg/dL Mag 1.7 mEq/L Phosphorous 4.7 mg/dL Glucose 185 mg/dL Albumin 2.9 g/dL Lactic Acid 6.0 mEq/L For ease of navigation, the scenario above will be populated in each of the following questions. The question will be listed in bold font after the scenario.
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 mls. 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’ myocardial hypertrophy may be related to which of the following?
