An 82-year-old woman with prior medical history of stage IV colon cancer and chronic obstructive pulmonary disease presented to the medical intensive care unit with newly diagnosed community acquired pneumonia and acute kidney injury. The patient presented with acute onset of shortness of breath, nausea, generalized weakness, bilateral lower extremity swelling and decreased urine output. She was transferred for short term dialysis in the setting of multiple electrolyte abnormalities, including hyperkalemia of 6.4 mmol/l, as well as a creatinine of 6.5 mg/dl. The following imaging of the right internal jugular vein was performed with ultrasound during preparation for placement of a temporary triple lumen hemodialysis catheter.

Figure 1. Panel A: Transverse ultrasound image of the right neck. Panel B: Longitudinal ultrasound image of the right neck, centered on the internal jugular vein.

Based on the above imaging what would be the best location to place the dialysis catheter? (Click on the correct answer for an explanation and discussion)

1. Left internal jugular vein
2. Right femoral vein
3. Right internal jugular vein
4. Right subclavian vein

A 48-year-old man with a history of hypertension, intravenous drug abuse, hepatitis C, and cirrhosis presented with 1 day of melena and hematemesis. While in the Emergency Department, the patient was witnessed to have approximately 700 mL of hematemesis with tachycardia and hypotension. The patient was admitted to the Medical Intensive Care Unit for hypotension secondary to acute blood loss. He was found to have a decreased hemoglobin, elevated international normalized ratio (INR), and sinus tachycardia. A bedside echocardiogram was performed.

History of Present Illness

A 64-year-old man underwent three vessel coronary artery bypass grafting (CABG). His intraoperative and postoperative course was remarkable other than transient atrial fibrillation postoperatively for which he was anticoagulated and incisional chest pain which was treated with ibuprofen. He was discharged on post-operative day 5. However, he presented to an outside emergency department two days later with chest pain which had been present since discharge but had intensified.

PMH, SH, and FH

He had the following past medical problems noted:

• Coronary artery disease
• Coronary artery aneurysm and thrombus of the left circumflex artery
• Dyslipidemia
• Hypertension
• Obstructive sleep apnea, on CPAP
• Prostate cancer, status post radical prostatectomy penile prosthesis

He had been a heavy cigarette smoker but had recently quit. Family history was noncontributory.

Physical Examination

His physical examination was unremarkable at that time other than changes consistent with his recent CABG.

Which of the following are appropriate at this time? (Click on the correct answer to proceed to the second of four panels)

1. Chest x-ray
2. Electrocardiogram (ECG)
3. Troponins
4. 1 and 3
