Decreasing host susceptibility:
- immunization - chemoprophylaxis post exposure
26
Eliminating the source of the pathogens:
- general sanitation measures - specialized equipment
27
Interrupting routes of transmission:
- special equipment handling - barrier/isolation precautions - disposable equipment
28
Standard precautions apply to:
- Blood - All body fluids - nonintact skin - mucous membranes
29
PPE:
- gloves - masks - N-95 - Gowns
30
Airborne precautions
Negative-pressure isolation room and use of Respiratory protective equipment by health care workers and visitors to room. During transport, patient should wear a surgical mask
31
Droplet precautions
Gloves, mask, and eye protective eyewear; infected patients should wear a surgical mask
32
____ is the first step in all equipment processing
Cleaning
33
___ act by reducing surface tension and forming an emulsion with organic matter
Soaps
34
1. Bactericidal: 2. Bacteriostatic: 3. Sporicidal: 4. Virucidal:
1. Method to kill bacteria 2. Method and techniques that inhibit growth 3. Methods to destroy spores 4. Methods to destroy virus
35
______ destroys the vegetative form of all pathogens except bacterial spores
Disinfection
36
Types of disinfectants
- Alcohols - Acetic acid - Bleach - Hydrogen peroxide
37
____ destroys all microorganisms
Sterilization
38
Types of sterilants
- incineration - cider (alkaline glutaraldehyde) - sonacide (acid glutaraldehyde)
39
3 major issues for disposable equipment
- cost - quality - reuse
40
Respiratory Hygiene
1. education of patients and employees 2. posted signs 3. source control measures (covering mouth) 4. hand hygiene 5. spatial seperation
41
___ is the most important way to prevent transmission of microorganisms via contact transmission
Handwashing - 15 sec scrub: b/w patients - 10 min scrub: prior to specialized procedures - 2 min scrub: arriving or leaving hospital
42
5 basic components of effective communication
1. Sender: individual/group transmitting the message 2. Message: information or attitude communicated by sender (verbal or nonverbal) 3. Channel: method used to transmit messages (written or oral) 4. Receiver: target of the communication 5. Feedback: allows sender to measure communication success
43
Senders communication skills:
- eye contact - attitude - experience - culture - self concept
44
Things that can improve the skill of a sender
- seek to relate to people rather than control them - value disagreement as much as agreement - share information rather than telling
45
4 primary sources of conflict
1. poor communication 2. structural problems 3. personal behavior 4. role conflict
46
5 basic strategies for handling conflicts
1. competing 2. accommodating 3. avoiding 4. collaborating 5. compromising
47
ambulation should begin as soon as the patient is _____

48
What is voltage?
power behind electrical energy
49
Most homes and hospitals are powered with ___ -V power sources
120
50
Voltage:
the power potential behind the electrical energy
51
Current:
the flow of electricity from a point of higher voltage to a lower point. (this represents the greatest danger to the provider and patient)
52
Harmful effects of the body due to electricity depend on:
1. the amount flowing through the body 2. the path is takes 3. the duration the current is applied
53
Current = ____ / _____
current = voltage / resistance (increased resistance decrease current)

Macroshock
high current usually greater than 1ma is applied externally to skin
57
Microshock
small amount of current less than 1ma bypasses the skin and follows a direct, low-resistance path onto the body
58
True or False: a third (ground) wire prevents dangerous buildup of voltage than can occur on the metal frames of some electrical equipment
True
59
Effects of electrical shock
high average to skin can cause sustained myocardial contraction, temporary respiratory paralysis, and burns

Pull pin Aim nozzle Squeeze handle Sweep nozzle across base of fire
63
R.A.C.E.
Rescue patient from immediate area of fire Alert other personnel to the fire Contain the fire Evacuate other patients
64
Components of medical record
Admission sheet, History and Physical Exam, Health Maintenance and immunization, physicians orders, progress notes, nurses notes, medication record, allergies, vital signs, I/O sheet, Lab sheets, consultant sheet, surgical and treatment consent, anesthesia and surgical record, specialized flow sheet, advanced directives

67
About ___% of all patients admitted develop an HAI
5%
68
Standard precautions apply to:
- Blood - All body Fluids - Nonintact skin - mucous membranes
69
Acute exposure to EtO gas can cause:
- airway inflammation - nausea - diarrhea - dizziness
70
Chronic exposure is associated to:
- resp. infection - anemia - altered behavior
