QUESTION 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.

attempted to quit several times in her 40s, and had her last cigarette on her

test results from that exam are listed below.
BP: 178/90
HDL: 62 mg/dl
LDL: 190 mg/dl
