Therefore, platelets undergo degranulation the exocytosis of their cytoplasmic granules and release of factors that promote hemostasis. Aggregation is occurs when serotonin (vasoconstrictor), ADP (attracts more platelets and stimulates their degranulation), and thromboxane A2 (stimulates degranulation and vasoconstriction) are released. Thus it can quickly seal a small break in blood vessel. Coagulation is the last process of the hemostasis. It has three ways; intrinsic, extrinsic and common pathways.
1) Coronary artery disease occurs when fatty deposits called plaque build up inside the coronary arteries. The coronary arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it narrows the arteries and reduces the amount of blood that gets to your heart. This can lead to serious problems, including heart attack. 2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries.
It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle. It also could be acute, which is the result from plaque suddenly rupturing. The inner wall of an artery is damaged. Some fatty deposits or plaques made up of cholesterol and other cellular waste products will accumulate at a site of injury in a process called atherosclerosis, the hardening of arteries. If the surface of the plaques break or rupture, blood cells, called platelets will clump or clot at that site to try and repair the artery.
Nasogastric tube also bypasses the lower esophageal sphincter and permits reflux. Dry mucous membranes and thick secretions is another complication. This is seen in patients with extended use of noninvasive ventilation. To prevent this from occurring, humidification for noninvasive ventilation devices should be provided along with daily oral care. Another complication that occurs is aspiration of gastric contents, especially if emesis occurs during noninvasive ventilation.
* In certain inflammatory conditions or other disorders, fluid also can accumulate beneath the retina without a tear or break. Aging-related retinal tears that lead to retinal detachment As you age, your vitreous may change in consistency and shrink or become more liquid. Eventually, the vitreous may separate from the surface of the retina — a common condition called posterior vitreous detachment (PVD). It's also called vitreous collapse. As the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear.
Sensing lesser flow, arterioles auto regulates by dilating, which reduces peripheral resistance. 2. Too Much Vasoconstrictor Activity: Postulated hypertension as the cause of essential hypertension. The list includes norepinephrine, angiotensin, aldosterone, thromboxane, and endothelin. More than a small proportion of hypertension, but that they all contribute in some circumstances to pressure regulation.
“Make sure appropriate hand hygiene is used. Meticulous infection prevention precautions are required to prevent infections, with particular attention to hand hygiene and standard precautions” (Ackley & Ladwig, 2011, pg. 492). The nurse should also teach the patient what the signs and symptoms of infection are. “Teach the patient and family the symptoms of infection that should be promptly reported to a primary medical caregiver” (Ackley & Ladwig, 2011, pg.
In this paper, we will discuss the importance of blood transfusion and reasons why it is a current ethical health care problem. There are four major ethic principles will be used to evaluate and apply reasons to this problem; autonomy, beneficence, nonmaleficiene, and justice. Blood Transfusion According to Torphy & Lynm (2012), Blood transfusion is a medical treatment that replaces blood loss during serious injuries, surgery, disease, lack of blood due to blood disorders and illness. When blood that were donated and come from another person and use for transfusions. Patients who have illnesses and common blood disorders are highly recommended having blood transfusions to replace missing blood and to help treat the disease.
Introduction Blood pressure is the force exerted by the blood against the walls of the vessels in which it is contained It is essential in every assessment of a patient to get the baseline vitals (Valler-Jones, Wedgbury, 2005). Accurately taking these levels can greatly assist healthcare providers in diagnosing possible illnesses or diseases that a patient may have. That is why it is imperative to accurately take a patient’s blood pressure. Misreading a patient’s blood pressure can lead to wrongly diagnosing a patient with hypertension, hypotension or many other abnormalities. There are many techniques in which to measure blood pressure and there has been much debate on which technique is the most accurate.
Hospital-acquired infections are preventable and preventing them is straightforward: a code of cleanliness. Hands should be cleaned frequently with an anti-bacterial soap for at least 30 seconds. Gowns, masks and gloves should be worn frequently so that pathogens aren’t transmitted to the patient during treatment. Moreover, when moving a patient, the patient should wear a mask and should be moved only when necessary (Isolation Precaution Guidelines for Hospitals n.d.). People go to the hospital in order to get better from whatever ailment is troubling them.
