Dysrhythmias * they can result in deviations from a normal HR and/or rhythm, causing decreases in cardiac output. Some dysrhythmias are lethal, causing a complete loss of CO, which result in cardiopulmonary arrest. Other dysrhythmias are apparent on ECG's but are symptomless correct answer: Disruptions in the cardiac conduction pathway or disorders of the electrical impulse conduction within the heart HR x SV = CO HR is how many times the heart beats per minute; SV is the amount of...

Physio Exam 3 Questions With Accurate Answers. Describe the Frank-Starling law of the heart - answerThe 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 the contractility of the heart in that wh...

The nurse is discussing cardiac hemodynamics with a nursing student. The nurse explains preload to the student and then asks the student what nursing interventions might cause increased preload. The student correctly answers which of the following? Ans: Correct response: Application of antiembolytic stockings Explanation: Preload is the amount of blood presented to the ventricles just before systole. Anything that assists in returning blood to the heart (eg, antiembolytic stockings) or...
