A 53-year-old male presents to the Christiana Hospital Emergency room complaining of headache and nausea with vomiting and muscle cramping. Questioning of the patient found that he has been increasing tired and restless. His wife notes that he has become confused when driving or at home. Bloodwork and urine was as follows: Blood [Na+] 123 mEq/L [K+] 4.9 mmol/L [Cl-] 91 mM [HCO3-] 26 mM [Ca2+] 1.1 mmol/L [PO4] 5.1 mg/dL pH 7.32 Urine [Na+] 40 mEq/L [K+] 65 mEq/L [HCO3-] 0.15 mEq/L 24hr vol. 537 ml Blood pressure readings were 170/120 sitting with HR of 102. The patient exhibits distended jugulars and pitting edema. Medical records show that the Px was in a car accident within the last month and had some head trauma. What is abnormal about the Px bloodwork. What is abnormal about the Px urinalysis? What is causing the elevated HR and BP? Diagnosis?

Step 1
Abnormalities in the patient's bloodwork: The patient's sodium level is low (normal range is 135-145 mEq/L), indicating hyponatremia. The patient's blood pH is also slightly low (normal range is 7.35-7.45), indicating mild acidosis. Show more…

A 42-year-old man comes to the emergency department because of a 3-day history of left-sided flank pain and a 3-month history of severe swelling of his legs. He has no history of serious illness. He is 178 cm (5 ft 10 in) and weighs 76 kg (168 Ib); BMI is 24 kg/m?. Blood pressure is 125/80 mm Hg; all other vital signs are within normal limits. Physical examination discloses tenderness to palpation over the left flank and 3+ edema of the lower extremities. Urinalysis is negative for blood and shows 4+ protein. CT scan of the abdomen shows a thrombosis of the left renal vein. If a renal biopsy specimen were obtained in this patient, it would most likely show which of the following findings: A) Amyloid deposition B) Anti-glomerular basement membrane antibody deposition C) IgA deposition D) Segmental areas of mesangial sclerosis E) Thickening of basement membrane

A 60-year-old man entered the emergency room department after 2 days of "not feeling so well." Patient history revealed a myocardial infarction 5 years ago, when he was prescribed Digoxin. Two years ago, he was prescribed a diuretic after periodic bouts of edema. An ECG performed at the time of admission indicated the presence of cardiac arrhythmia. Chemistry testing performed on admission showed the following results: Analyte Result Digoxin 1.4 ng/mL (therapeutic range 0.5-2.2 ng/mL) Na+ 137 mmol/L K+ 2.5 mmol/L Cl- 100 mmol/L HCO3- 25 mmol/L Mg2+ 0.4 mmol/L Ionized Calcium 1.0 mmol/L Which results are abnormal? For each abnormal result, determine if it is high or low compared to the reference ranges discussed in lecture. The Digoxin level is within the recommended therapeutic range. The Digoxin results mean that the arrhythmia is not likely due to the patient's history of myocardial infarction, so what might be causing the patient's arrhythmia? How could this patient be treated?
A 72-year-old man with severe congestive heart failure is brought to the emergency department because of a 5-day history of malaise and vomiting. He takes no medications. His pulse is 104/min, respirations are 35/min, and blood pressure is 90/64 mm Hg. Physical examination shows dusky-colored skin, peripheral cyanosis, and 10-cm jugular venous distention. Crackles are heard over the lung bases bilaterally. Cardiac examination shows an S3. There is 2+ pitting edema to the knees bilaterally. Laboratory studies show: Serum Na+: 127 mEq/L K+: 5.2 mEq/L CI-: 79 mEq/L HCO3-: 17 mEq/L Urea nitrogen: 100 mg/dl Glucose: 171 Mg/dl Creatinine: 8.4 mg/dl Urine Glucose 1+ Ketones absent Arterial blood gas analysis on 28% oxygen pH: 7.35 Pco2: 32 mmHg Po2: 154 mmHg HCO3- :17 mEq/L Which of the following is the most likely cause of the anion gap in this patient? A) Alcoholic ketoacidosis B) Diabetic ketoacidosis C) Hyperperfusion D) Hypoalbuminemia E) Metabolic alkalosis F) Milk-alkali syndrome G) Renal failure H) Respiratory alkalosis
