4.Sample answers:
a.Direct contact: Transmission of disease through
touching, kissing, or sexual contact
b.Indirect contact: Personal contact with contam-
inated blood, food, water, etc.
c. Vectors: Mosquitoes, ticks, and lice transmit
organisms from one host to another.
d.Airborne: Spread of droplet nuclei through
coughing, sneezing, or talking- a.Inflammatory response: A protective
 mechanism that eliminates the invading
 pathogen and allows tissue repair to occur
 b.Immune response: Involves specific reactions in
 the body as it responds to an invading foreign
 protein such as bacteria or, in some cases, the
 body’s own proteins. The body responds to an
 antigen by producing an antibody.
- a.Intact skin and mucous membranes protect the
 body against microbial invasion.
 b.The normal pH levels of gastric secretions and
 of the genitourinary tract help to ward off
 microbial invasion.
 c. The body’s white blood cells influence resistance
 to certain pathogens.
 d.Age, sex, race, and hereditary factors influence
 susceptibility.
- a.Assessing: Early detection and surveillance tech-
 niques are critical. The nurse should inquire
 about immunization status and previous or
 recurring infections, observe nonverbal cues,
 and obtain the history of the current disease.
 b.Diagnosing: The direction or focus of nursing
 care depends on a nursing diagnosis that accu-
 rately reflects the patient’s condition.
 c. Planning: Effective nursing interventions can
 control or prevent infection. Nurses should
 review assessment data and consider the cycle
 of events that results in infection control as
 patient goals are formulated.
 d.Implementing: The nurse uses principles of asep-
 tic technique to halt the spread of microorgan-
 isms and minimize the threat of infection.
 e.Evaluating: The nurse can intervene in, and
 improve, a patient’s outcome by assessing
 the person at risk, selecting appropriate nursing
 diagnoses, planning and intervening to
 maintain a safe environment, and evaluating
 the plan of care to determine whether it is
 working.
 8.Sample answers:
 a.Patient’s home: Wash hands before preparing
 food and before eating; use individual personal
 care items such as washcloths, towels, and
 toothbrushes.
 b.Public facilities: Wash hands after using any
 public bathroom; use individually wrapped
 drinking straws.
 c. Community: Use sterilized combs and brushes
 in beauty and barber shops; examine food han-
 dlers for evidence of disease.
d.Healthcare facility: Use standard aseptic
techniques to prevent further spread of a present
organism and prevent nosocomial infections.- a.Instituting constant surveillance by infection-
 control committees and nurse epidemiologists
 b.Having written infection-prevention practices
 for all agency personnel
 c. Using practices that help promote the best pos-
 sible physical condition in patients
- a.Nature of organisms present: Some organisms are
 easily destroyed, whereas others can withstand
 certain commonly used sterilization and disinfec-
 tion methods.
 b.Number of organisms present: The more organ-
 isms present on an item, the longer it takes to
 destroy them.
 c. Type of equipment: Equipment with narrow
 lumens, crevices, or joints requires special care.
 Certain items may be damaged by sterilization
 methods.
 d.Intended use of equipment: The need for medical
 or surgical asepsis influences the methods used in
 the preparation and cleaning of equipment.
 e.Available means for sterilization and
 disinfection: The choice of chemical or physical
 means of sterilization and disinfection takes
 into consideration the availability and
 practicality of the means.
 f. Time: Time is a key factor. Failure to observe
 recommended time periods for disinfection and
 sterilization significantly increases the risk for
 infection and is grossly negligent.
- a.Hospital: The infection-control nurse is respon-
 sible for educating patients and staff about
 effective infection-control techniques and for
 collecting statistics about infections.
 b.Home care setting: The infection-control
 nurse’s duties include surveillance for agency-
 associated infections, as well as education, con-
 sultation, performance of epidemiologic
 investigations and quality improvement activi-
 ties, and policy and procedure development.
- a.Risk for Infection related to altered skin
 integrity/burns
 b.Effective nursing interventions can control or
 prevent infection. The nurse should review
 patient data, consider the cycle of events that
 result in the development of an infection, and
 incorporate infection control as a patient goal.
 13.Use standard precautions for the care of all
 patients in the ER. The additional concern with TB
 necessitates using airborne precautions in addition
 to standard precautions.
