A 62-year-old woman presents to the emergency department with a 2-hour history of sharp chest pain. She says that the pain is worse when she inhales and is relieved by sitting up and leaning forward. Her past medical history is significant for rheumatoid arthritis, myocardial infarction status post coronary artery bypass graft, and radiation for breast cancer 20 years ago. Physical exam reveals a rubbing sound upon cardiac auscultation as well as increased jugular venous distention on inspiration. Pericardiocentesis is performed revealing grossly bloody fluid. Which of the following is most specifically associated with this patient's presentation?
AMyocardial infarction
BMalignancy
CUremia
DRheumatoid arthritis
EViral illness
A 72-year-old man presents to the emergency department because of difficulty breathing and sharp chest pain. The chest pain increases in intensity with lying down, and it radiates to the scapular ridge. Approximately 3 weeks ago, he had an anterior ST-elevation myocardial infarction, which was treated with intravenous alteplase. He was discharged home in a stable condition. Current vital signs include a temperature of 38.1 (100.5°F), blood pressure of 131/91 mm Hg, and pulse of 99/min. On examination, heart sounds are distant and a scratching sound is heard on the left sternal border. ECG reveals widespread concave ST elevations in the precordial leads and PR depressions in leads V2-V6. Which of the following is the most likely cause of this patient condition?
ARecurrent infarction
BMyocarditis
CAortic dissection
DDressler’s syndrome
EVentricular aneurysm
A 36-year-old woman presents to the emergency department with chest discomfort and fatigue. She reports that her symptoms began approximately 1 week ago and are associated with shortness of breath, swelling of her legs, and worsening weakness. She’s been having transitory fevers for about 1 month and denies having similar symptoms in the past. Medical history is significant for systemic lupus erythematosus (SLE) treated with hydroxychloroquine. She had a SLE flare approximately 2 weeks prior to presentation, requiring a short course of prednisone. Physical exam was significant for a pericardial friction rub. An electrocardiogram showed widespread ST-segment elevation and PR depression. After extensive work-up, she was admitted for further evaluation, treatment, and observation. Approximately 2 days after admission she became unresponsive. Her temperature is 100°F (37.8°C), blood pressure is 75/52 mmHg, pulse is 120/min, and respirations are 22/min. Heart sounds are muffled. Which of the following is a clinical finding that will most likely be found in this patient?
AWarm extremities
BPericardial knock
CDecreased systolic blood pressure by 8 mmHg with inspiration
DJugular venous distension
EUnequal blood pressure measurements between both arms
