W UPDATED EXAM LATEST VERSION OF QUESTIONS AND ACCURATE DETAILED SOLUTIONS 2024-2025 COMPLETE DOCUMENT FOR STUDY ALREADY GRADED A+ A 60-year-old woman has a resting heart rate of 70 beats per minute, arterial pressure of 130/85 mm Hg, and normal body temperature. Use the pressure-volume diagram of her left ventricle below to answer Questions 1-4. What is her cardiac output in milliliters per minute? A) 2000 B) 3000 C) 4000 D) 6000 E) 7000 E) This patient has a heart rate of 70 beats per minute. The cardiac output can be determined by using the following formula: cardiac output = heart rate × stroke volume. The stroke volume can be determined from the figure, which is the volume change during the C-D segment, or 100 milliliters. By using this formula, you can determine that the cardiac output is 7000 milliliters per minute. 2. When does the first heart sound occur in the ventricular pressurevolume relationship? A) At point B B) Between point A and point B C) Between point B and point C D) Between point C and point D E) Between point D and point A A) During the diastolic filling phase, the mitral and tricuspid valves open and blood flows into the ventricles. At point B the isovolumic contraction phase begins, which closes the AV valves. The closing of these valves causes the first heart sound. [Show More]
