Exam 1 Information Flashcards
What are infectious diseases
Pathogens that cause disease by disrupting vital body processes or stimulating the immune system to mount a defensive reaction. Symptoms may include high fever and inflammation.
Where can pathogens enter the body
Through the skin, respiratory system, digestive system, or reproductive system.
Which type of injury is at high risk for infection when it closes up.
Puncture injury
First stage of Pathogen Infection
Incubation- Not infectious
Second stage of Pathogen Infection
Prodromal- start to see signs and symptoms (Isolate Person)
Third Stage of Pathogen Infection
Acute- Highest development of disease, most at risk for spreading disease.
Fourth Stage of Pathogen Infection
Decline- start to recover and feel better, high risk for relapse.
Fifth Stage of Pathogen Infection
Recovery- recovering from pathogen, develop immunity (Permanent or temporary)
What is acquired Immunity
immunity that develops with exposure to various antigens
What are the four types of infectious diseases
Sporadic (random)
Endemic (certain area)
Epidemic (Widespread)
Pandemic (throughout the world, everywhere)
How is Hepatitis B spread
It is spread through unprotected sex, sharing needles, needlesticks or SHARPS
Will an individual always have symptoms if infected with hepatitis B
It is possible for an individual infected with HBV will exhibit no signs or symptoms and the virus may go undetected. Thus, the disease may be unknowingly transmitted to others through exposure to blood or other bodily fluids
What is the rate of infection for health care providers
8700 infected each year. 200 a year die.
What is the Human Immunodeficiency Virus (HIV)
A retrovirus that combines with a host cell.
May infect cells of the immune system, T-cells, B cells, Macrophages.
What are signs and symptoms of HIV
Fatigue, weight loss, muscle/joint pain, painful/swollen glands, night sweat, and fever.
What is Acquired Immunodeficiency syndrome (AIDS)
Most people with HIV will develop AIDS
No protection against infections
Extremely vulnerable to illnesses, opportunistic infections and cancer.
Kaposi’s Sarcoma and Non-Hodgkins Lymphoma.
What are the statistic for AIDS
2011: 1.2 million Americans have HIV infection
50,000 NEW INFECTIONS EACH YEAR
Since 1981, 600,000 people have died of AIDS
About 50% develop AIDS within 10 years of being infected with HIV
Life span about 2 years after developing AIDS
What is OSHA Occupational Safety and Health Administration
Sets standard requirements for employers to follows to ensure employee safety with regard to occupational exposure to bloodborne pathogens.
What are the employee requirements for OSHA
Any employee who has the potential for occupational exposure to blood or other potentially infectious materials (OPIM) is required to receive training according to the bloodborne pathogen standard.
What are some preventions for OSHA
- Engineering Controls
- Work Practice Controls
- Personal Protective Equiptment
- Universal Precautions
- Body Substance Isolation
Engineering and work practice controls
Used to eliminate or minimize exposure to bloodborne pathogens.
Employer is responsible for full cost.
Must be regularly maintained or replaced if not effective.
Required to provide hand washing facilities.
All work practices must minimize or eliminate the risk of exposure.
Contaminated Needles or Sharps
Any object that can penetrate the skin (needles, scalpels, broken tubes, dental wires)
Reusable sharps must be place in a clearly labeled puncture resistant, leak proof container immediately after use until they can be reprocessed
What are Universal Precautions
Aggressive standardized approach to infection control
Treat all human blood and certain body fluids as if they contain bloodborne pathogens.
What are materials that require universal precautions
blood, semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, any body fluid with visible blood, any unidentifiable body fluid, saliva from dental procedures.
What are some materials that do not require universal precautions
Feces, Nasal secretions, Sputum, Sweat, Tears, Urine, Vomitus, Unless they contain visible blood.
What are some Personal Protective Equipment
gloves, gowns, aprons, face shields, masks, eye protection, lab coats, shields, and resuscitation bags.
What are employer requirements for Hepatitis B Vaccine
Must be provided by employer if employee is at risk for exposure.
Must be offered at a convenient time, during normal working hours.
Employer cannot require you to use your health insurance to pay for the vaccine.
What are CONTRAINDICATIONS for hepatitis B
Prohibited if sensitive to yeast or any other component of the vaccine.
Consultation with a physician is required for people with heart disease, fever or other illnesses. Consultations also recommended if pregnant or breastfeeding.
What happens if you are exposed to an OPIM
It must be reported to the supervisor
Testing may be provided for exposure upon employee request.
Which infection is of more concern in regards to athletic
Hepatitis B
What are the concerns in terms of exclusion from sports for an HIV infected athlete?
Athlete should avoid exhaustive exercise which can weaken the immune system.
Must have a medically sound reason for exclusion based on objective medical evidence.
What are the measures taken for Acute HBV
Removal from contact sports
What are the measures taken for chronic HBV
should be received from competition.
What is Right to Know
As a health care provider you have the right to know if an athlete has an infectious disease, must maintain information confidential.
What is the appropriate measures for caring for wounds
See the athlete on a daily basis. Before game/practice and after to clean if necessary and avoid infections.
What is trauma
An injury or wound produced by some sort of force (internal, external)
What is a mechanical injury
force, changes the structure and state of rest of a muscle
What are the four tissue properties
Load, Stiffness, Stress, Strain
What is load
External force, causes a reaction within the tissue
What is stiffness
Ability of a tissue to resist a load
What is stress
internal resistance to a load
What is strain
Internal change in tissue (seen in muscles and/or tendons)
Stress-strain
Beyond the yield point, creep begins thus injury starts past this point.
What is creep
Deformation in shape (constant fluid)
What is yield point
Point at which elasticity is almost exceeded
If deformation persists, following release of load permanent or plastic changes result
When yield point is far exceeded mechanical failure occurs resulting in damage.
What type of tissue loading
Tension, Compression, Shearing
What is tension
Constant stress pulling
What is compression
squishing movement (fractures, disc)
What is shearing
Cross stress on fibers (ex. blisters)
What is Bending
Two force pairs act as opposite ends of a structure (4 points)
Three forces cause bending (3 points)
Already bowed structures encounter axial loading
What is torsion
Loads caused by twisting in opposite directions from opposite ends
Shear stress encountered will be perpendicular and parallel to the loads.
What is acute injury
Something that comes on rapidly or suddenly (direct blow)
What is a chronic injury
Longterm, overuse, repetitive stress over time.
What are the anatomical characteristics of Musculotendinous Unit Injuries.
Composed of contractive cells that produce movement
Posses following characteristics: Irritability, Contractility, Conductivity, Elasticity.
What is a muscle strain
Stretch, tear or rip to muscle or adjacent tissue.
What causes a muscle strain
Abnormal muscle contraction is the result of:
- Failure in reciprocal coordination of agonist and antagonist.
- Electrolyte imbalance due to profuse sweating.
- Strength imbalance.
What is a common site for tendon/muscle rupture
bicep muscle
What is a Grade 1 Strain
some fibers have been stretched or actually torn resulting in tenderness and pain and ROM movement painful but full range present.
