A patient has had a large anterior myocardial infarction last month and developed a ventricular aneurysm. He now has episodes of ventricular tachycardia that are not prevented or converted with antidysrhythmic agents. An implantable cardioverter-defibrillator (ICD) is implanted. Four days after surg...

What is vasogenic cerebral edema? answer Vasogenic cerebral edema is an increase in extracellular fluid caused by a breakdown of the blood-brain barrier with the resultant increase in vascular permeability. This cerebral edema begins locally and becomes more generalized. Common causes are trauma (i...

A patient is in cardiac and respiratory arrest. The selection of medications to reestablish cardiac function would stimulate the sympathetic nervous system beta1 receptors. This stimulation would result in increased automaticity and which of the following? a. Increased myocardial contractility b....

Which of the following would be the earliest auscultatory finding in left ventricular failure (LVF)? A. Crackles B. S3 C. Murmur of mitral regurgitation D. Pericardial friction rub answer B. S3 LVF would be the most subtle because early changes are usually subtle changes. Choose "S3." ...

cardiac output answer The volume of blood ejected from the left side of the heart in one minute. 4-8 L/min HR x SV Cardiac Index answer CO/BSA 2.5-4.3 Stroke Volume (SV) answer The amount of blood pumped out of the heart with each contraction. (Vol ejected with each beat) 60-100...

cardiac output answer The amount of blood that is pumped by the heart per unit time, measured in liters per minute (l/min). How is cardiac output determined? answer The stroke volume multiplied by the heart rate is the cardiac output. Stroke volume answer The amount of blood that is put out...
