7. Ischemic heart disease a. Review the blood supply of the heart. Know what myocardial regions are supplied by each coronary artery and how to determine which coronary artery is dominant. b.
Case Study Using the following American Heart Association (AHA) resources on blood lipids and heart disease, determine the risk of heart disease for the following three people and make recommendations on what they need to do to modify their blood lipids and lower their risk. * Diet and Lifestyle Recommendations Revision 2006: A Scientific Statement from the American Heart Association Nutrition Committee: http://circ.ahajournals.org/cgi/content/full/114/1/82 * Go to this link and do a search on blood lipids: http://americanheart.org * Scientific Statement on Managing Abnormal Blood Lipids: http://circ.ahajournals.org/cgi/content/full/112/20/3184#TBLU13 * Executive Summary of the Scientific Statement on Diagnosis and
Cardiac Catheterization Worksheet Name two reasons for a cardiac catheterization? Cardiac caths are used for many reasons some are: 1. To check the blood pressure and blood flow in the chambers of the heart. 2. Check the blood flow of the coronary arteries and help determine whether surgeries or other procedures are needed to open possible blocked blood vessels.
4. Discuss the role of thrombolytic therapy in a patient with an AMI. Include indications, and contraindications for use of thrombolytics. Thrombolytic therapy is the use of drugs to break up or dissolve blood clots, which are the main cause of both heart attacks and stroke. 5.
2. You have been called upon to demonstrate the technique for listening to valve sounds. c. Where would you position your stethoscope to auscultate: iii. The aortic valve of a patient with severe aortic valve incompetence? 1.

Year 10 Pre-Diploma Biology Heart Dissection Introduction This lab practical allows you to identify and compare the size, shape and tissue type of the major chambers and vessels of the heart. The goal of the lab is not just to observe anatomy, but to associate structure with function. The heart is a pump for blood that comes into the right atrium, goes out to the lungs through the right ventricle, returns through the left atrium, and leaves again through the left ventricle - a double circulation. Each chamber is separated by valves that prevent the backflow of blood. Try and figure out where the various components are, how each works, especially how the shape, composition, and even texture of each part contribute to its function.
Sepsis & MODS CCRN Review Hildy Schell,RN,MS,CCRN,CCNS CNS, Adult Critical Care UCSF Medical Center Objectives By the end of class, the participant will be able to: 1. Identify the pathophysiologic mechanisms of sepsis that lead to MODS. 2. List the clinical presentation of a patient with severe sepsis & MODS. 3.
Lab Report: Coronary transport of the heart Introduction: The heart is an organ of the cardiovascular system. Using blood as the transport vehicle, this system functions to transport substances around the body that are vital to homeostasis. In this lab, the experiment will be to locate and identify the various structure of the heart and also to trace the coronary circulation. Also with prepared slides, the objective will be to compare and contrast the different structures of cardiac muscle to that of smooth muscle. Materials: Heart model, Marieb and Mitchell laboratory manual, microscopic slides, camera, and microscope Procedure: Each lab group observed the external and internal surfaces of the heart, locating and identifying the three layers and the heart wall, the four chambers of the heart and the structures associated with them, locating and identifying the fossa ovalis, pectinate muscles, papillary muscles and chordae tendinae.
One of the very important objects used in the nursing profession is the Electrocardiogram (ECG or EKG) machine which is used to monitor the heart of patients. An electrocardiogram machine is used to monitor a patient’s heart. Each beat of the heart is triggered by an electrical impulse normally generated from special cells in the upper right chamber of the heart. An electrocardiogram — also called an ECG or EKG — records these electrical signals as they travel through a patient’s heart. A nurse can use an electrocardiogram to look for patterns among these heartbeats and rhythms to diagnose various heart conditions.
