(76 cards)
What is pain?
Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage.
How is pain defined according to the person experiencing it?
Pain is whatever the person says it is, and it exists whenever the person says it does.
Why is pain different from vital signs like pulse or blood pressure?
Pain cannot be measured objectively like pulse or blood pressure.
What is one role of pain in the body?
Pain can be a warning of potential injury to the body.
How is pain classified?
Pain is classified and assessed by origin, duration, pattern of occurrence, quality, intensity, and time since onset.
What is cutaneous/superficial pain?
Cutaneous/Superficial Pain usually occurs due to a skin or subcutaneous injury and is usually short in duration.
What characterizes deep somatic pain?
Deep somatic pain originates in ligaments, tendons, nerves, blood vessels, and bones, and can be longer in duration.
What is visceral pain?
Visceral pain is caused by stimulation of deep internal pain receptors, often in the abdominal cavity, cranium, or thorax.
What is radiating pain?
Radiating pain starts at the origin but extends to other locations.
What is referred pain?
Referred pain starts at the origin but extends to more distant locations.
What is phantom pain?
Phantom pain is pain perceived to originate from an area that has been surgically removed.
What is psychogenic pain?
Psychogenic pain is believed to arise from the mind, with the patient perceiving pain without an identifiable physical cause.
Define acute pain.
Acute pain is usually short in duration, has a rapid onset, and may last up to 6 months.
Define chronic pain.
Chronic pain lasts 3-6 months or longer and interferes with daily activities.
What is transduction in the context of pain?
Transduction is the process when nerve cells (nociceptors) become activated by mechanical, thermal, or chemical stimuli.
What is transmission in pain processing?
Transmission is when peripheral nerves carry the pain message to the dorsal horn of the spinal cord and then to the brain.
What role do neurotransmitters play in pain perception?
Neurotransmitters are endogenous chemicals that aid in pain transmission, sending messages to the thalamus of the brain.
What is pain perception?
Perception involves the recognition and interpretation of pain in the frontal cortex.
What is modulation in pain processing?
Modulation changes the perception of pain by facilitating or inhibiting pain signals through the analgesia system.
What are some effects of unrelieved pain on the endocrine system?
Unrelieved pain can trigger hormones that decrease insulin release and increase glucose release.
How does pain affect the cardiovascular system?
Pain leads to hypercoagulation, increased heart rate, blood pressure, cardiac workload, and oxygen demand.
What impact does pain have on the musculoskeletal system?
Unrelieved pain can lead to impaired muscle function, fatigue, and immobility.
What is the Fifth Vital Sign in pain assessment?
Pain is assessed every time vital signs are checked, but its classification as the fifth vital sign has been debated.
What is the most common method to assess pain?
The numerical rating scale from 0 to 10 is the most common method.
