42
Healthcare associated infection
infections associated with healthcare delivery in any setting. The inability to determine with certainty where the pathogen is acquired since patients may be colonized with or exposed to potential pathogens outside of the healthcare setting, before receiving health care or may develop infections caused by those pathogens when exposed to the conditions
43
Antiseptics
inhibit the growth of micros
44
Disinfection
agents that destroy pathogens other than spores. Use of a chemical procedure that eliminates virtually all recognized pathogenic micros but not necessarily all micro forms on inanimate objects

56
Critical Medical Device
critical instruments and medical device require sterilization. the item enters sterile tissue or the vascular system. these items present a high risk of infection if the items are contaminated with micros, especially bacterial spores (surgical instruments, cardiac caths, urinary caths)
57
Isolation
measures designed to prevent the spread of infections or potentially infectious microorganisms to health personnel, clients, and visitors
58
Communicable Disease
Infectious agent can be transmitted to an individual by direct or indirect contact or as an airborne infection
59
Standard Precautions (Tier One)
Apply to all clients receiving care in hospitals, regardless of diagnosis or possible infection status. Apply to blood, all body fluids, secretions, excretions, except sweat, non-intact (broken) skin, mucous membranes. Designed to reduce transmission of micros from recognized and unrecognized sources.
60
Transmission-based Precautions (Tier Two)
Used in addition to standard precautions for clients with known or suspected infections that are spread airborne, droplet, or contact
61
Airborne Precautions
clients known to or suspected of having serious illnesses transmitted by airborne droplet nuclei smaller than 5 microns (measles, chickenpox, TB)
62
Droplet Precautions

64
Respiratory/Cough Etiquette
covering mouth and nose during coughing and sneezing, using tissues to contain R secretions with prompt disposal into a no-touch receptacle, offering a surgical mask to persons who are coughing to decrease contamination of the surrounding environment, turning head away from others and maintaining spatial separation, ideally > 3 feet
65
Standard Precautions
perform proper hand hygiene, wear clean gloves when touching blood, body fluids, secretions, excretions, and contaminated items, wear mask, eye protection or face shield if splashes or sprays of blood, body fluids, secretions, or excretions are expected, place used needles into sharps containers and do not attempt to recap needles, one hand scoop

Philosophies of nursing MCC
people are dynamic beings who continuously interact with their environment in unique ways, all people have basic needs which they strive to satisfy and toward which their behavior is directed, people's ability to meet basic needs is affected by a variety of factors such as culture, age, health, finances, and environment, unmet basic needs may result in health problems, health problems may affect a person's ability to meet basic needs, nursing is a profession which has evolved to assist people to meet basic needs, nursing is base on knowledge from nursing theory and nursing research, the natural and behavioral sciences and the humanities, the nursing process is a method allowing nurses to fulfill their roles uner NYS practice act to diagnose and treat human responses to actual and potential health problems, nursing care is directed toward promoting wellness, restoring optimal health, preventing illness, providing rehabilitation and supporting death with dignity, the graduate nurse demonstrates competence in professional behavior, communication, comprehensive assessment skills, effective clinical decision making, therapeutic nursing interventions, teach-learning processes, collaboration and management of care
