You are called to see a patient in the ER who has presented with shortness of breath. You immediately recognize Teresa J, the 65-year-old female who was previously admitted for several weeks with acute lung injury earlier in the year. A quick review of her chart reminds you that she also has a history of poorly controlled diabetes and premature CAD with a prior MI at age 62. She looks distressed and is only able to talk in short phrases. She describes chest pain on the left side that gets worse when she coughs or moves. She has been getting weaker over the last 3 days. Her sputum is yellow, but she denies hemoptysis. She stopped taking all of her medications a week ago (furosemide, ASA, antihyperglycemics, metoprolol).
