“pain is what the person says it is“
Nociception
Ability to feel pain
4 processes: transduction, transmission, perception, modulation
Neuropathic (pathophysiological) pain
Results from abnormal processing of sensory input by the CNS due to damage
Can be caused by stroke, chemotherapy, or tumors
Transduction
Cell damage at the injury site, the first step of the nociception process
Transmission
Message gets sent from an injury site through the spinal cord to the brainstem
Perception
The “ow” factor
Modulation
Neurons in the brainstem travel down the spinal cord and release hormones to counteract the pain. They inhibit pain impulses to mask or deal with pain. These pain inhibiting hormones are produced in the pituitary gland and the hypothalamus
Gate control mechanism
Creating a stimulus around or above a pain point so that the new stimulus can travel to the brain first and distract from the pain occuring
Best on mild to moderate pain
The “gate“ can be closed with competing impulses
Pain threshold
The point at which pain is felt
Pain tolerance
The amount of pain someone can withstand
Often on a scale of 1-10
Endogenous analgesia system
The body’s natural defense of producing analgesics in the pituitary gland and hypothalamus and diffusing that to the affect site to provide pain relief
Cutaneous (superficial) pain
A sensation of pain arising from the skin, can be a symptom of underlying issue
Visceral pain
Arises from the visceral organs, a well localized pain ex.tumor on the breast, appendicitis
Deep somatic pain
Related to parts of the body (like joints, muscles) where pain is made worse with movement occuring at the injury or infection site
Radiating pain
Pain that begins in one area but spreads
Referred pain
When the nerve fibers from one region of the anatomy transfer to the nerve fibers of another area
Phantom pain
Pain in a limb that isn't there, the reason for this is unclear but it's theorized that it could be due to increased neural activity and sensativity
Psychogenic
Caused by anxiety and other psychological issues
6
For pain to be classified as chronic it must be present for at minimum _ months
Intractable pain
Chronic and highly resistant to relief pain, requires multiple methods of releif
Acute pain
Rapid onset, short duration pain
Disappears as the tissue heals
Associated with injury/surgery
Loss
Undesired change or removal of a valued object, person, or situation
Grief
Physical, psychological, and spiritual response to a loss
Bereavement
State of grieving
Mourning

occurs when all vital organs and systems cease to function
whole brain death, higher brain death, cardiac death (irreversible)
T
T or F: unrelieved pain will result in adverse psychological and physical effects
Pain assessment scales
WILDA: stands for words, intensity, location, duration, aggravating/alleviating factors. A subjective approach where the nurse asks questions to gauge the pain level.
visual analog scale: faces on a pg. depicting various pain states
Pain intensity scale: a number scale of 1-10 can be paired with the visual analog scale
Pain types
acute - short form, eases as damage to tissue heals
chronic - longer than 6 months
nociceptive - caused by injury trauma and inflammation
neuropathic - a repeated feeling of pain in the absence of a painful stimuli
intractable - pain that is highly resistant to relief
* these can overlap ex. chronic intractable pain or chronic neuropathic pain

The quality of life is as important as the length of life
Ex of advanced directive
Living will

2 = occasional drowsiness but easy to arouse
3 = frequent drowsiness, will fall asleep during conversation, reduce pt dosage
4 = somnolent, minimal to no response, discontinue use and/or administer narcan
