Aortic Stenosis |Aortic stenosis is a narrowing of the aortic valve in the heart. This restricts the flow of blood through | |the valve. The left ventricle then needs to contract harder to pump blood into the aorta. Mild narrowing | |may not cause any symptoms. More severe narrowing can cause various symptoms and may lead to heart | |failure.
Hemorrhagic stroke (~17%)- A blood vessel breaks open, causing blood to leak into the brain 3. Define the term collateral blood flow, and describe how this and other factors affect the development of stroke. The brain has s circular vascular structure called the circle of Willis and two pairs of arteries that feed the circle. So most areas of the brain receive blood from more than one collateral blood vessel. The type, and severity of stroke symptoms depends on the location of the and severity of brain ischemia 4.
What is Hypertension? It is most commonly known as high blood pressure. The body system that is involved is the cardiovascular system. The organ that is involved is the heart. The causes for homeostatic imbalance in hypertension are medication, weight, smoking, heredity, drinking, external stressors, age, disease, and race.
When the nurse is developing a teaching plan to prevent the development of heart failure in a patient with stage 1 hypertension, the information that is most likely to improve compliance with antihypertensive therapy is that a. hypertensive crisis may lead to development of acute heart failure in some patients. b. hypertension eventually will lead to heart failure by overworking the heart muscle. c. high BP increases risk for rheumatic heart disease. d. high systemic pressure precipitates papillary muscle rupture. B Rationale: Hypertension is a primary cause of heart failure because the increase in ventricular afterload leads to ventricular hypertrophy and dilation.
What is a sickle cell crisis? Why is it concerning? • A sickle cell crisis is when the RBC is sickled shaped which prevents the RBC’s and oxygen to get to the tissue leading to extreme pain. There are 3 forms of a sickle cell crisis: • Vaso-occlusive crisis occurs when blood flow to tissues is obstructed by sickled RBCs, leading to hypoxemia and ischemia. • Acute sequestration event occurs when blood flow from an organ such as the liver, lungs, or spleen is obstructed by sickled RBC.
Diabetic neuropathies damage peripheral nerves, which components pf the reflex arc is the most likely to be damaged in nicks situation? i. Sensory receptors 7. Which division of the ANS would be affected and be causing nicks GI tract symptoms? j. PNS 8. Nicks light headedness is caused by a condition known as orthostatic hypotension, a rapid drop in blood pressure upon standing up.
Here are some of the adverse effects associated with anabolic steroid use. In the Cardiovascular system the lipid profile changes, your blood pressure elevates, and you get a decreased myocardial function. The effects on the Endocrine system include Gynecomastia, decrease sperm count, testicular atrophy, and impotence and transient infertility. Dermatological issues include acne and even male pattern baldness. In the Hepatic system you have an increased risk of liver tumors and liver damage.
Congestive Heart Failure (CHF) Congestive heart failure (CHF) is a condition in which the heart's function as a pump is inadequate to meet the body's needs. The symptoms of congestive heart failure vary, but can include fatigue, diminished exercise capacity, shortness of breath, and swelling. The treatment of congestive heart failure can include lifestyle modifications, addressing potentially reversible factors, medications, heart transplant, and mechanical therapies. The heart has two atria (right atrium and left atrium) that make up the upper chambers of the heart, and two ventricles (left ventricle and right ventricle) that make up the lower chambers of the heart. The ventricles are muscular chambers that pump blood when the muscles contract.
