Funds exam 4 Flashcards
involves the skin or subcutaneous tissue
cutaneous pain
originates deeper in the bones, tendons, ligaments, & vasculature
somatic pain
results from activation of pain receptors in organs or hollow viscera, tends to be poorly located & may have cramping, pressing, throbbing, or aching quality
visceral pain
from damaged or malfunctioning nerves
neuropathic pain
what type of pain originates in nociceptors which are peripheral somatosensory nerve fibers that transduce noxious stimuli
nociceptive pain
what are the 4 processes involved in nociception?
transduction, transmission, perception, and modulation
a powerful vasodilator that increases capillary permeability and constricts smooth muscle
Bradykinin
important hormone-like substances that send additional pain stimuli to the CNS
Prostaglandins
sensitize receptors on nerves to feel pain and increase the rate of firing of nerves
substance P
conduct pain stimuli toward the brian
small nerve fibers
conduct movement (walking, shaking hand)
large nerve fibers
when a nonpainful input closes the nerve gates to painful input, which prevents pain sensation from traveling to the central nervous system
gate control theory
minimum intensity of stimulus that’s perceived as painful
pain threshold
can affect the patients perception of pain (slowly walking into a pool)
adaptation
the process by which sensation of pain is inhibited or modified
modulation of pain
natural morphine like endorphins, enkephalins, and endorphin dynorphins
neuromodulators
increase in BP and pulse can indicate what
pain
what acronym do you use to assess pain
OLDCARTS ICE
scale with faces on it for kids above 3 and adults
Wong-baker faces
pain tool for kids too young to point to a face for pain
Beyer oucher pain scale
pain assessment tool for neonates that uses objective data
CRIES pain scale
pain scale for infants and kids 2months-7years who are unable to give their pain a number
FLACC scale
pain scale for infants, kids, and adults who cant use the numeric rating or faces (uses objective data)
Comfort scale
what does non-pharmacological pain control do
it is an alternative or used in addition to pain meds
what is biofeedback
doing something like deep breathing
sedation scale
s=asleep
1=AAO
2=drowsy but easy to arouse
3=reduce the dosage bc pt. drifting off
4=consider use of naloxone bc pt. no response to stimuli
what pain relief is used for mild to moderate pain, inflammation, and fever
nonopioid analgesics
what are some nonopioid analgesics
NSAIDS & Tylenol
what pain relief is used to stimulate opioid receptors or bind with pain receptors to block pain impulse
opioids or narcotic analgesics
what are examples of opioids or narcotic analgesics?
Mu agonists (acute & chronic) and agonist-antagonists (mild to severe)
what pain relief is used for mild pain or in conjunction with opioids for moderate to severe pain?
anticonvulsants, antidepressants, muscle relaxants, corticosteroids, etc
what are side effects of opioids?
constipation, dry mouth, respiratory depression, n/v, sedation, hypotension
when patients have the oposite effect of a pain reliever
paradoxical reactions
what do you need to asses before and after administering pain meds?
RR
receptor that provides senses of touch, pressure, & vibration
mechanoreceptors
specialized nerve cells in the skin
thermoreceptors
receptors that detect sound waves
hair cells in cochlea
receptors that are for taste and smell
chemoreceptors
what does gustatory mean
impaired taste
sensory deficit vs deprivation
deficit- impaired sense (inabilities)
deprivation- lack of senses
what is hemispatial neglect
only seeing half of the vision (thinking its the full circle but its just half)
eyes that dont stay stationary on an object when the head is turned
doll eyes
astigmatism
imperfection of eye curvature
retinopathy
damage to the blood vessels in the retina from diabetes
central deafness
damage to cochlear nuclei causing deafness
what is serum osmolality range
280-300
what is urine osmolality range
200-800
what is urine specific gravity range
1.01-1.02
how do you treat hypovolemia
with rehydration and an isotonic solution
paracentesis
drain fluid from abdomen
thoracentesis
drain chest cavity
when water passes from low concentration to high concentration
osmosis
