Test 3 Flashcards
Nociceptive pain
pain from tissue damage
Referred pain
pain perceived at a site next to or at a distance from the sight of injury. EX: Heart attack feels pain at arm but location is heart
Nueropathic pain
abnormal function of the nervous system due to injury/disease
Note that neuropathic pain is perceived as sharp, burning or radiating pain from peripheral or central nervous system injury or disease
Why does a warmpack decrease the perception of pain?
Stimulates sensory receptors that will decrease pain signals to the brain
Dilates blood vessels which increase flow of oxygen to the muscle
Facilitates stretching of soft tissues that will decrease stiffness and becomes more flexible/loose for more comfort
Helps resolve inflammation
Analgesic
absence of pain or noxious stimulation, relief of pain. “loss of pain” (aspirin or Tylenol)
Anesthetic
loss of sensation of due to medication, drugs, or nerve damage; numbness and refer to the lost of the ability to feel sensation and pain. “loss of feeling” (numbing meds) causes muscle weakness & relaxation
What does anesthetic stop?
Anesthetic stop transmission of nerve impulses
What alters pain perception?
Analgesic alters pain perception
Where does the perception of pain occur?
Perception of pain occurs when nociceptors are stimulated & transmit signal thru sensory neurons in spinal cord. Then sent to brain, then sent to CNS
What has priority in the nervous system pain or sensation?
Sensation has priority in the nervous system.
How does this knowledge explain pain control from the use of warm, cool or massage?
Infection control and universal precautions
nosocomial infection
acquired infections resulting from exposure to micro-organism pathogen. EX: health care environment, hospital, clinic, nursing homes
What is the term for the human, animal or insect that harbors a pathogen (disease organism)?
Host or Reservoir - Human, animal or insect that harbor the disease
What are the most common ways to transmit a communicable disease?
*direct contact (most common) air borne skin to skin oral ingestion soil water food open or closed wound blood excretions secretion
Universal Precautions
preventing transmission of blood-borne disease, consider all body fluids infectious, use goggles, masks, gowns, gloves. Protects the therapist, patients, family, & friends.
the type of protection and actions the PTA would do to prevent infection from the following transmission methods
Wash hands before & after contact with patient
After restroom
after eating
after removing gloves
after contact with body fluids, blood, wounds, dressing and contaminated objects
between tasks or procedures of the same patient in order to prevent contamination to different body parts
alcohol sanitizer
wear gloves, gown, mask, goggles, shoes covers
needle sharp containers
biohazard disposal equipment
Air, blood, body fluids, contact
