Module 4: Discussion Must post first. Mrs. K is a 60-year-old white female who presented to the ER with complaints of her heart “beating out of my chest”. She is complaining that she is having increased episodes of shortness of breath over the last month and in fact has to sleep on 4 pillows.

In the past week, she’s been experiencing fatigue and decreased urine output. Her past history is positive for an acute anterior wall myocardial infarction and coronary artery bypass surgery. She was a 2 pack a day smoker, but quit 8 years ago. On physical examination, auscultation of the heart revealed a rumbling $3 gallop and inspiratory crackles.
