5. What are the potential contraindications that can prevent someone from having a cardiac catheterization? What is the contraindication that must be considered in Robert Wilson’s case? Why is this of concern? There are potential contraindications to getting a cardiac catheterization, though the only contraindication is the inability to provide an informed consent. There have been unstable patients how have tolerated this procedure but with high risk patients, the nurse has be cautious of…

Chapter 1 Atherosclerosis Structure of the normal artery: Cell types composing the normal artery: Endothelial Cells: The endothelial cell (EC) of the arterial intima constitutes an important contact surface with blood. It plays an important role in vascular homeostasis. This blood compatibility is due to presences of heparan sulfate proteoglycan molecules on the surface of the EC. These molecules can serve as a cofactor for antithrombin III, which inhibit thrombin. The surface of the EC also…

High blood pressure, or hypertension, is a condition in which the force of the blood against the artery walls is high enough that it can eventually cause health problems. When the heart beats, is crates pressure that pushes blood through the arteries. Blood pressure is the result of this “push”, or force. There are two forces; one occurs when the blood pumps out of the heart and into the arteries and the second occurs as the heart rests between beats. These two forces each represent the numbers…

Task 2 Part A Cebita Santhosh Q1. The three main types of blood vessels in the circulatory system are veins, arteries and capillaries. The veins carry deoxygenated blood from the capillaries back to the heart. The arteries carry blood away from the heart to your tissues. The capillaries are the smallest of the body's blood vessels, only one cell thick and are found in the muscles and lungs. Q2. Eating too much salt can raise your blood pressure because of the extra water stored in the…

atherosclerosis, the main contributor to MI. “Atherosclerosis a common disorder characterized by yellowish plaques of cholesterol, other lipids, and cellular debris in the inner layers of the walls of arteries (Mosby, 2013, pg.153).” Fatty deposits (lipids) are circulating through the blood and become stuck to the artery walls, due to an injury in the endothelial lining of the blood vessel. After some time, the build up of plaque activates the body’s inflammatory process. Macrophages are…

of 115 beats/min, respiratory rate 22 breaths/min, blood pressure of 82/40 mmHg, and oxygen saturation of 88% on 2L nasal cannula. A vasopressor is needed to address this patient’s hypotension. Prior to placement of an arterial line at the radial artery, which of the following describes the most appropriate diagnostic test? A. Instruct the patient to flex the elbow to 90 degrees while the physician shakes hands with the patient. The patient is then asked to supinate and the physician provides…

Amlodipine (Norvasc): This drug blocks calcium from entering the muscles in your arteries and in your heart. Calcium helps muscles contract, so by blocking this it helps the muscles of your arteries relax allowing them to open up more. Having more space reduces resistance of blood flow making it easier for the blood to flow. It also relaxes the arteries that go to your heart reducing resistance, increasing the blood flow to your heart. Having less resistance then reduces your blood pressure…

body. Several conditions can hamper the ability of the heart to effectively pump blood. Abnormalities or muscle disease or heart valves can cause failure of the heart to maintain an adequate blood circulation. Coronary artery disease, high blood pressure, or narrowed or clogged arteries can compromise the blood…

This technique can be used with all strains and for single and repeat samples. Use of the artery is normally used for larger volume samples or for arterial blood, but carries a greater risk of haematoma and bruising (Diehl et al., 2001). Local anaesthetic cream (e.g. EMLA cream) can be applied to the site 30 minutes prior to blood sampling.…

sustained, elevated blood pressure of 140/90 or greater. This condition develops over many years. Blood pressure is determined by the amount of blood the heart pumps and the amount of resistance to blood flow in the arteries. The more blood the heart pumps, the narrower the arteries become and therefore causes a higher blood pressure. Uncontrolled hypertension can lead to serious complications such as heart attack and stroke. Essential Hypertension and Secondary Hypertension are the two…
