Vida Darley NRS 202 Ati skills module: infection control. Prevention and controlling infections are very important in so many areas of life. There are so many measures that are taken to control the spread of infections. As health care professionals we have to have the knowledge of nosocomial infection also known as hospital acquired infections so that we can have proper precaution equipment and ways of preventing them. Number one safest way to prevent infection is proper hand washing technique

TASK 1 The body ’s first line of defence against pathogens uses mostly physical and chemical barriers such as sweat‚ skin‚ tears‚ mucus‚ stomach acid‚ and so on. Our skin and other membranes which line the body passages are fairly effective in keeping most pathogens out of the body. Mucus can trap pathogens‚ which are then washed away or destroyed by chemicals. Tears‚ sweat‚ and saliva have certain chemicals which can kill different pathogens. Bacterial spores and fungi are naturally present

cause perforations in the infected cells. When both of these mechanisms are through they will help destroy pathogens in the infected body. This diagram will help with the visualization of these mechanism and their processes. Killer T-cells combine with antigens on the surface of any invading cell and release a powerful group of chemicals called lymphokines. Some lymphokines kill the pathogens directly‚ others stimulate lymphocytes to become active and help increase the inflammation so that there are

entry and dealing with the pathogens once they have breached the outer defences of the body. Once a pathogen is inside the body‚ the immune system must recognize the pathogen as foreign and dispose of it. The overall immune system is divided into two separate systems that do work together to protect the body. The Innate system‚ is the initial immune response from childhood which functions in the same way whether or not the individual has already encountered the same pathogen. Whereas‚ the Adaptive

Running head: RISK MANAGEMENTS ASSESSMENT SUMMARY Risk Managements Assessment Summary Health care organizations use risk management methods to guard their assets against likely threats brought on by legal liability. An important component of risk management programs inside the long-term care setting is the ability to reduce the amount of avoidable accidents and injuries and to reduce the financial severity of claims. Long-term care facilities offer a wide array of services to residents
