Case Studies on Cardiac Function
This is the first case study that is required for the class. Please submit a paper (doesn’t have to be long; you could even give me bullet-point answers to the questions listed below) that answers all of the questions posed after Case Study 1. I have included an easy second case study which, if you complete it, will be worth extra credit. Answers to the first Case Study are worth 25 points and responding to Case Study 1 is required work for the course. The extra credit, which is not required, will be worth a total of 10 points. Please check the syllabus for the due date.
A.O. is an 89-year-old woman with a long history of systolic heart ...view middle of the document...
5. What is the rationale for the use of each of A.O.’s medications in managing her heart disease?
Digitalis to increase force and velocity of contractions to increase SV, decrease heart rate, promotes urine production due to improved kidney perfusion.
Furosemide to decrease preload and central venous pressure decreasing ventricular filling pressure and decreasing BP
KCl to replace what was lost because of the Furosemide
Nitroglycerine to dilate blood vessels, and decrease preload and decreases cardiac workload.
K.R. is a 46-year-old man admitted to the emergency department with unremitting chest discomfort. The pain started while he was shoveling snow from his walkway. He had experienced chest discomfort with activity previously, but the pain had subsided with rest and he sought no medical help. This time the pain did not subside and became increasingly severe, radiating to his left arm and lower jaw. In the emergency department, an ECG and cardiac enzymes were obtained. The cardiac monitor showed sinus tachycardia with occasional premature ventricular complexes. K.R. was treated with 2 L nasal oxygen, thrombolytic therapy, sublingual nitroglycerin, and IV morphine sulfate. When he was pain free, he was transferred to the cardiac unit for...
