After you are done exercising, listen to your heart sounds again.Discussion Questions95250192405003. Indicate on the diagram where you located the clearest sound.4. Did the sound of your heartbeat change after exercising? Describe the difference you heard.5. What causes the characteristic heart sounds?6. What causes heart murmurs?Blood PressureBP at REST1. Make sure the arm is wrist up and at rest2. Roll sleeves up (if need be) and place the cuff just above the elbow. The tubes of the cuff should be lined up with your brachial artery on the inside of the arm. Make sure the cuff is completely deflated.3. Avoid talking, laugh etc., and relax. Legs should not be crossed. DO NOT move your arm.4. Place stethoscope bell under the cuff on the inner surface of the arm5. Pump cuff to about 140-150 mm Hg, then slowly release air while listening.6. The first sound you hear, when the needle first bumps up, is the systolic pressure.7. The last sound you hear, when the needle slightly goes up at the end, is the diastolic pressure.8. Immediately release the air after you get a reading.9. DO NOT take it again for a couple of minutes if you could not get an accurate reading!10. Once you get an accurate reading, add your BP result to the class data and record the class average. Add two other students BP data in the data table below.Name:Systolic PressureDiastolic PressureBP (systolic/diastolic)Class averageBP after Exercise11. Exercise moderately for 1 minute by doing jumping jacks.12. Have a partner take your BP immediately afterwards and record it. Switch roles with one another (take theirs after exercising).13. Add your BP to the class, and get two other students BP data for your table data below.Name:Systolic PressureDiastolic PressureBP (systolic/diastolic)Class average14. What was the effect of exercise on BP?15. How does the body benefit from this change in BP during exercise?16. What’s considered a normal average adult BP?17. How would the BP of an anxious patient visiting a doctor be different than if the patient is calm?18. Would BP rise or fall if a patient suffers from an aortic aneurism (clot in aorta)? 19. Based on your answer in question 18, explain your reasoning.20. In atherosclerosis, plaque builds up in the arteries occluding the lumen (opening). How would this affect BP? Is this an example of hypertension or hypotension?21. What techniques could lead to a faulty blood pressure reading? List three! ................
