Caleb's Heart Case Study
Short Answer Questions:
1. Dr. Baker spends a long time listening to (auscultating) Caleb’s heart.
a. Where on the thoracic surface do you auscultate to the tricuspid, mitral (bicuspid), pulmonary, and aortic valves?
For the tricuspid valves, the sounds of the heart are typically heard in the right sternal margin of the 5th intercostal space. For the Mitral (bicuspid) valve, sounds are heard over the heart apex, in the 5th intercostal space. This is in line with the middle of the clavicle. (Lutchman, 2016, PowerPoint). The pulmonary valve sounds are heard in the 2nd intercostal space at the left sternal margin. Lastly, the aortic valve sounds are heard in the 2nd intercostal space, which is at the right sternal margin (Marieb & Hoehn, 2015, 671-673).
b. Where do you think would be the best place to auscultate Caleb’s abnormal heart sound? Explain your answer.
Because Caleb’s defect lies between his left and right ventricles, the best place to hear Caleb’s abnormal heart …show more content…
Baker heard between the lub and dup sound. Because he has an abnormality in the hole between his two AV ventricles, once the AV valves close initially and the first sound is heard, then the ventricles contract and there is a hole between his two ventricles, creating the abnormal murmur sound. Once the blood passes from the left to right ventricle and the semilunar valves close the final dup sound is heard (Marieb & Hoehn, 2015, 687-688).
3. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. a. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole?
During systole, the contraction phase, I would expect the blood in Caleb’s heart to move from left to right ventricle (Marieb & Hoehn, 2015, 685-687).
b. Based on your understanding of blood pressure and resistance in the heart and great vessels, explain your answer to question
