01:26Factors Affecting the Risk of Infection
11.4K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
