1. Rashidah is a 55-year-old female who is experiencing acute chest pain and shortness of breath. She describes the pain as “pressure and squeezing.” When she becomes nauseous and light-headed, her son insists that he take her to the emergency room.
 
Health History: She started smoking when she was 18, attempted to quit several times in her 40s, and had her last cigarette on her 50 th birthday. She has been overweight for most of her adult life, but has gained 20 pounds in the last few years, which increased her BMI to 34. The last time she had a physical exam was when she turned 50. Her vital signs and blood test results from that exam are listed below.

1. Because of the dysfunction of Roberto’s left ventricle, which of these findings is most likely?

Decreased cardiac output

End-diastolic volume is increased significantly

QUESTION 14

1. Briefly describe how beta-blockers will influence Roberto’s heart function, specifically the physiology of the ventricles.

1 points   

QUESTION 15

1. Briefly describe how ACE-inhibitors will influence Roberto’s heart function.

QUESTION 16

1. Roberto’s doctor orders several tests of his heart function, including “ejection fraction.” Briefly explain what an ejection fraction measures. (Include what a normal measurement would be.)
