Question: A 58 year old man, George Gilman is married with 4 children. He works long hours at a desk job, rarely gets home before 8pm and was diagnosed with CAD 2 years ago after complaining of chest pain. He states he utilizes a meal delivery service to his office for lunch and dinner and smokes 1/2 pack of cigarettes per day. George walked into the emergency department complaining of severe heartburn he is contributing to his recent order of buffalo wings at lunch. He is seeking care for pain and nausea. During the initial assessment, what cues does George's interview provide for the nurse? What are the concerns? What labs or diagnostics are needed at this stage to help give George a diagnosis? Why are those labs/tests used?
