Effects of Hyper/Hypokalemia and calcemia on EKG Hypokalemia causes U waves Hyperkalemia causes peaked T waves Normal BP? 90-120/60-80 Normal HR? 60-100 bpm Normal CO? 4-8 L/min Normal SVR? 800-1,200 dynes/seconds Normal PVR? 37-250 dynes/sec/cm5 Normal SVo2? 60-80% Normal PAP? Systolic: 15-30 mm Hg Diastolic: 4-12 mm Hg Normal...

What is the most important sign in a critically ill pt? Why? - Correct answer-Tachypnea Indicates metabolic acidosis (often 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. What is the dx? - Correct answer-Cardiac tamponade; obstru...

A patient admitted with sepsis has a pulmonary artery catheter placed that also measures SvO2. During a routine assessment, the nurse notes that the patient's SvO2 is 56%. The nurse knows that this indicates:oxygen supply is not equal to demand. Which hemodynamic changes are associated with mitral stenosis?Elevated left atrial pressure, pulmonary artery occlusive pressure, and pulmonary artery diastolic pressure; normal left ventricular end-diastolic pressure

How does COPD result in atrial fibrillation and predisposition to PEs? - COPD causes pulmonary hypertension, right ventricular hypertrophy, and right atrial enlargement. The right atrial enlargement causes stretching of the atrial tissue and frequently results in atrial dysrhythmias. SA blocks, second-degree AV block type I, and third-degree AV heart block at the level of the AV node would occur in _______________ occlusion - RCA (as seen in inferior wall MIs) There is (more/less) risk of b...
