An 80-year-old woman comes to the urgent care clinic with dyspnoea on exertion. On physical examination, her blood pressure is 100/70, and her pulse is 75. She has no pulsus paradoxus. Her jugular veins are distended, and she has distant heart sounds. In addition, she has extra third and fourth heart sounds. Her liver is enlarged, and she has pedal oedema. She has occasional premature ventricular contractions on her electrocardiogram. A chest x-ray reveals clear lung fields with a dilated cardia...

What is the most important sign in a critically ill pt? Why? - ANSWER-Tachypnea Indicates metabolic acidosis w/ respiratory alkalosis compensation A pt misses dialysis for a few days and comes in with fluid overload. He's tachycardic and tachypneic. On physical exam, you find JVD, pulsus paradoxus (20 mmHg drop during inspiration), and HoTN (80/40) with distant, muffled heart sounds. Lungs are clear to auscultation.
