Q

Pain Process

Which 4 substances are involved in the transduction phase? Explain each of them.

A
  1. Bradykinins: powerful vasodilator that increases permeability, constricts smooth muscle, and triggers histamine release.
  2. Prostaglandins : send additional pain stimuli to the CNS.
  3. Substance P: neuropeptide that makes nerves feel pain and increases rate at which nerves fire.
  4. Serotonin: a hormone that can act to stimulate smooth muscles, stop gastric secretion, and produce vasconstriction.

Q

Pain Process

Which two fibers are involved in the transmission phase?

A
  1. Afferent Fibers: carries impulses from the pain receptors toward the brain.
  2. Efferent Fibers: carries information away from the CNS to the body.

Q

Pain Process

Describe the perception of pain and the pain threshold.

A
  1. Perception: sensory process that occurs when a stimulus for pain is present.

2.Pain Threshold: minimum intensity of a stimulus that is seen as painful.

Q

Pain Process

Describe the 3 things involved in Pain Modulation.

A
  1. Endogenous Opioid Compounds: are neuromodulators, naturally present, morphine-like regulators in the spinal cord and brain.
  2. Endorphins: produced at neural synapses, powerful pain-blocking chemicals that produce euphoria.
  3. Enkephalins: neurotransmitter, produces even more powerful effect than endorphins.

Q

Explain the Gate Control Theory in simple terms.

A
  1. Stimulation of small diameter fibers sense pain and cause the gates to open up.
  2. Stimulation of large diameter fibers such as heat, cold, mechanical, and pressure causes the gates to close.
  3. Amount of activation in the small fibers versus the large fibers controls the overall perception of pain.

Gate Control Theory is the basis for cold therapy, massage, distraction, and TENS therapies.

Q

What are nociceptors?

A

They send signals along sensory neurons to the spinal cord and then to the brain for translation.

The brain will send the signal back down motor neurons to the site of pain causing the body to respond to pain.

Q

What are the 6 categories of pain stimuli? Give examples in each category.

A
  1. Biological: bacteria, viruses (flu, pneumonia)
  2. Chemical: smoke, cleaning solution (smoke inhalation from fires- fireman)
  3. Electrical: electrical burns (finger in the socket- children are at risk)
  4. Thermal: heat, cold (frostbite)
  5. Mechanical: fractures, shearing forces, bending (trauma, surgery)
  6. Cellular: hypoxia is the most common cause (MI, sickle-cell disease)

Q

Describe Visceral Pain

A
  • Body organs and cavities in the chest, abdomen, and pelvic areas.
  • Most often caused by disease, pain is diffuse.
20
Q

Describe Referred Pain

A

Pain that is felt at a location other than the site of the painful stimulus or origin of pain.

21
Q

Describe Breakthrough Pain

A

An exacerbation of pain that happens suddenly, or in relation to a predictable or unpredictable trigger, despite the pain being pretty stable and controlled.

22
Q

What are the 3 types of breakthrough pain? Give an explanation for each.

A
  1. Incident Pain: short-term, predictable pain that happens with movement such as coughing or changing a dressing.
  2. Idiopathic Pain: unknown cause, lasts longer, difficult to treat.
  3. End-of-dose medication failure: pain at the end of 1 med dose before the next scheduled dose.
23
Q

How can we prevent End-of-Dose Medication Failures?

A

Increase medication dose or shorten the time between doses.

Q

What are 7 Pain Risk Factors?

A
  • Age

  • Obesity
  • Sedentary Lifestyle
  • Level of stress/anxiety

25
Q

What are 6 pain risk factors/barriers from the client’s perspective?

A
  • Reluctance to report pain r/t: indication of the progression of the disease, fear of taking the focus off the disease, the belief that pain is inevitable so nothing can be done about it.
  • cultural expectations that one should not report pain.
  • fear of becoming an addict
  • worries about medication side effects

Q

What are 6 pain risk factors/barriers from the HCP perspective?
