Shock States and Hemodynamic Management Practice Test

A 21-year-old male was stabbed in the chest to the left of the sternum. He is hypotensive with a blood pressure of 90/74 mmHg and a heart rate of 135 bpm. You note muffled heart sounds and prominent jugular venous distention. His breath sounds are clear and equal bilaterally.

A 68-year-old male with a history of hypertension and a previous myocardial infarction calls 911 for severe chest pain. Upon arrival, he is pale, diaphoretic, and hypotensive with a blood pressure of 84/60 mmHg. His heart rate is 118 bpm, and you hear bibasilar crackles on lung auscultation. A 12-lead ECG confirms an extensive anterior wall STEMI.
