Physio Exam 3 Labs and Quizzes UPDATED Exam Questions and CORRECT Answers Describe the Frank-Starling law of the heart - CORRECT ANSWER- The Frank-Starling law of the heart states that the stroke volume is directly proportional to the preload; an increase in EDV results in an increase in Stroke volume. The EDV is the amount of blood in the ventricles directly before the ventricles begin to contract so it can be referred to as the preload. Stroke volume is also directly proportional to...

UNE Pathophysiology Final UPDATED Exam Questions and CORRECT Answers According to the Frank-Starling law of the heart, increasing the _______________ within physiologic limits will cause increased contractility - CORRECT ANSWER- Preload Cardiac output is equal to heart rate time ________________ - CORRECT ANSWER- stroke volume The normal pacemaker of the heart is the ____________________ - CORRECT ANSWERSA node The __________________ nerves increase heart rate and contractibility. - C...

Therapeutic dosing and monitoring of warfarin (Coumadin) Treatment with warfarin should be initiated with standard doses of 5–10 mg. The initial adjustment of the prothrombin time takes about 1 week, which usually results in a maintenance dosage of 5–7 mg/d. The prothrombin time (PT) should be increased to a level representing a reduction of prothrombin activity to 25% of normal and maintained there for long-term therapy. When the activity is less than 20%, the warfarin dosage should be r...

It is managed with lifestyle changes and medications to prevent episodes of acute decompensated heart failure which race has a higher incidence of HF, african americans or caucasians? - african americans Frank-Starling Law - the greater the stretch, the ...

A nurse is discussINg the pressure generated at the end of diastole. Which term is the nurse describINg? Preload Afterload Systemic vascular resistance Total peripheral resistance ANSWERS A Preload, not afterload, is the volume and associated pressure generated IN the ventricle at the end of diastole. Afterload is the resistance to ejection of blood from the left ventricle. Systemic vascular resistance is related to afterload. Total peripheral resistance INcreases afterload. R...
