CHAPTER 34: Infection Prevention and Control
* Principles for infection control for the nurse and patient during care
NATURE OF INFECTION:
* Pathogen-infectious agents * Colonization- present or invaded host, grows and multiplies but does not cause infection * Communicable disease- transmitted from one person to the other
CHAIN OF INFECTION: a. Agent- residents for transient flora i. To cause disease depends on: 1. Does (number of organisms) 2. Virulence (ability to survive) 3. Ability to enter and survive 4. Host resistance b. Reservoir- source for pathogen growth but it may or may not survive ii. Needed ideal food source, aerobic, anaerobic, ideal amount of

Neutrophil ^ = bacterial infection iv. Monocytes ^ = phagocytosis (eats the dead and leaves exudate)
NURSING DX: Gather obj and subj data, look for clusters in data Ex Dx: risk for infection, imbal nut, impaired oral mucousa, risk for impaired skin integrity, social isolation, impaired tissue/skin integrity, role confusion, impaired breathing
PLANNING: Common Goals- 10. Preenting exposure to infectionous org 11. Controlling or reducing the extent of infection 12. Maintain resistance to infection 13. Client understanding of infection prevention and control techniques (like hand hygiene)
Set Priorities
Collaborate Care
IMPLEMENTATION: Health Promo- edu on immunos and vacc Acute Care- maintain fluids, adequate nut, rest, removal of debri on wound, wear PPE
ASEPSIS:
The practice that assist in reducing the risk of infection * Medical Asepsis- clean technique; reduces the number of organisms (hand hygiene, clean gloves) * Standard Precaution- medical asepsis technique to break the chain of infection a. Hand washing- 15 with friction while fingers pointing down, before and after care of any client b. Cleaning- removal of all soil with detergent or enzymatic products with a natural pH 1. If cleaning soiled material with blood, mucus etc wear gloves and eye wear.
John William Perry as a kid was always put in learning disability classes “he always felt he had something to prove” his mother Patricia Perry said. John had 1 brother named Joel and a sister named Janice. John was raised in Seaford long island during his lifetime he had accomplished many think like graduating college at New york university school of law. John learned how to speak 4 fluent languages (Spanish, Swedish, Russian and French) he also was learning Albanian. During his timeline he ran 4 marathons and swam around manhattan. John was an officer but he did much more like played an extra an woody allen and volunteered for the Kings County Society of prevention of cruelty to children. John WIlliam Perry accomplished many things before

In addition to diligent hand washing and the consistent use of other Standard Precautions, which measure will help reduce the transmission of Hepatitis?
Hands must be washed thoroughly, after every contact with potential source of contamination/ before food
II. You must constantly balance the glove being conditioned and the glove wanting to dry out because of use and the elements.
* To ensure effective hand washing is carried out when working with service users, giving personal care, handling/preparing food.
* Hand washing is the most important method of preventing the spread of infection by contact (Ayliffe et al 1999). The Nottingham University Trust Policy on Hand Hygiene (2009) states that there are three types of hand hygiene, the first is ‘routine hand hygiene’ which involves the use of soap and water for 15 – 20 seconds or the application of alcohol hand rub until the hand are dry. The second is ‘hand disinfection’ which should be used prior to an aseptic procedure by washing with soap and water and applying alcohol hand rub afterwards. The third is ‘surgical hand washing’ which is the application of a microbial agent to the hands and wrists for two minutes. In addition to which a sterile, disposable brush may be used for the first surgical hand wash of the day although continued use will encourage colonisation of microbes. The third example is the most appropriate to any O.D.P undertaking the surgical role as it is the best way for the surgical team to eliminate transient flora and reduce resident skin flora (World Health Organization 2010). The first and second are important to any O.D.P undertaking any other role within the Operating Department as this is the best way to reduce the transient microbial flora without necessarily affecting the resident skin flora
Hands were wet by a running tap and antiseptic detergents or liquid soap (5ml was poured onto the hands, the technique consisted of five backwards and forwards strokes in the motion of; palm to palm, each palm over the other hand’s back, interlocking palm to palm, each palm over the other hand’s back interlocked and then the rotational scrubbing of the fingers into each palm finalised by the rubbing of the wrists during a 30-second time span. Then the hands were rinsed with water for 15-seconds and dried with two paper towels for 15-seconds. (Ayliffe et all, 1978) Whilst this technique has strict timescales the WHO elects the timescale of roughly the time taken to sing “Happy Birthday” twice. This raises concerns over the approximates as this will differ from person to person. The procedure itself remains nearly exact except from the addition of turning the tap off with a towel to avoid recontamination and the exact timings are lost. This technique only stated to use running water, however no temperature was specified. Hand Washing for Life (200-) advises that water should not be above 110F as this temperature would cause hands become damaged by loosing delicate tissues on the skin. This can cause bacteria to become trapped and more difficult to remove, as well as cause pain to the worker. It is a legal requirement for health professions to take the necessary measures to
To ensure effective hand washing is carried out when working with service users, giving personal care, handling/preparing food.
The topic was chosen for a number of reasons, including the great need for improving hand hygiene, to preserve and promote positive care of patients, looking into issues which may hinder hand hygiene compliance.
(Nagel 22). Student nurses and volunteers should place emphasis on hand-washing before and after contact
Dirty hands is the common source of spreading infection. It is very important to keep hands clean to avoid getting infected and spreading infection in the community. It is important to wash hands to keep hands clean. There are two ways to keep hand clean, one way is wash hands with soap and warm water while rubbing hands together for minimum 15 to 30 seconds. Indication of washing hands with soap and water is when hands are visibly dirty, before and after eating, feeding, using the toilet, after coughing or sneezing, after using gloves, taking care of patients. There is also second way to clean hands, but it is advisable to wash hands with soap and water all the time, but it can ignore when soap and water is not available so it is okay to use hand gel or foam in the form of sanitizer. This helps to clean hands or kill germs when hands are not visibly dirty.
Steeve & Mallison (1975) stated hand hygiene has often been singled out as the most important procedure in preventing infection. Guidelines from national and international infection prevention and control organizations acknowledged that hand washing is the single most important procedure for preventing infections (Ganner and Favero,1985).
Within the essay I am going to discuss whether good hand hygiene practices are the single most important factor in preventing cross infection. Some may argue for this statement others against. Jeanes A (2005) refers to the NMC code of professional conduct (2004) who state that you must act to identify and minimise risk to patients and clients.
To wash hands regularly and effectively. This needs to be done after handling food, personal care, toileting etc.
