Assume that one ventricle of a child’s heart has an EDV of 90 mL, an ESV of 60 mL, and a cardiac output of 2.55 L/min. What are the child’s stroke volume (SV), ejection fraction (EF), and heart rate (HR)?a. SV = 60 mL; EF = 33%; HR = 85 bpmb. SV = 30 mL; EF = 60%; HR = 75 bpmc. SV = 150 mL; EF = 67%; HR = 42 bpmd. SV = 30 mL; EF = 33%; HR = 85 bpme. Not enough information is given to calculate these.
The end systolic volume from an individual’s heart was found to be 50 ml, the end diastolic volume was found to be 110 ml and the heart rate was 90 bpm. What is this individual’s stroke volume, ejection fraction and cardiac output (C.O)? Group of answer choices SV = 60 ml Ejection Fraction = 50% C.O = 3.4 l/min SV = 110 ml Ejection Fraction = 52% C.O = 4.4 l/min SV = 60 ml Ejection Fraction = 55% C.O = 5.4 l/min SV = 160 ml Ejection Fraction = 70 % C.O = 6.4 l/min

Group of answer choices Heart Rate End-diastolic volume Stroke Volume End-systolic volume 63) Carbon monoxide binds to hemoglobin _____times as strongly as oxygen does. Group of answer choices 25 200 50 100 2 64) When exercising, Starling’s Law comes into effect. Constantly contracting muscles will increase the venous return to the heart. Which of the following will be true in this case? Group of answer choices Local constriction of precapillary sphincters that control blood flow to the exercising muscle Decrease in Heart Rate Dilation of blood vessels that go to the digestive organs Decrease in the diameter of blood vessels to the exercising muscles Increase in…

Select the FALSE statement: /////////////////www. OA) This abnormal ECG results in increased stroke volume O B) In this abnormal ECG, the ventricles are not stimulated to contract by the SA node, the natural pacemaker. of the heart O C) This abnormal ECG is compatible with life so far as the individual does not engage in strenuous activities OD) This abnormal ECG results in decreased in CO OE) None of the above
An elderly man presents to the emergency department with chest pain. He has a history of stable angina and recent onset diabetes mellitus, but now the chest pain comes on with less exertion and takes longer to g0 away. An ECG and cardiac enzymes are ordered. If this man has unstable angina, what are the expected findings on ECG and cardiac enzyme testing? (4) Delta waves on the ECG and elevated cardiac enzyme levels (B) Low voltage ECG and elevated cardiac enzyme levels {€) No changes on ECG and elevated cardiac enzyme levels (D) ST-segment depressions on ECG and normal cardiac enzyme levels () ST-segment elevations with Q waves and Normal cardiac enzyme levels
