Q

Location

A
  • may be complicated because some pain radiate(spread or extend) to other areas
  • pain may also be referred(appear to arise in different areas) to other parts of the body;ie: cardiac pain may be felt in the shoulder or arm
  • visceral pain(pain arising from organs or hollow viscera) is often perceived in an area remote from the organ causing the pain.

Q

Etiology-Nociceptive Pain

A
  • is experienced when an intact, properly functioning nervous system sends signals tht tissues are damaged requiring attention and proper care
    ie: pain experienced following cut or broken bone tells you to avoid further damage until properly healed. pain then goes away when healed.

Q

Types of Painful Stimuli-Transduction

A

MECHANICAL
* trauma to body tissues - tissue damage, direct irritation of pain receptors, inflammation
* alterations in body tissues - pressure on pain receptors
* blockage of a body duct - distention of the lumen of the duct
* tumor - pressure on pain receptors, irritation of nerve endings
* muscle spasm - stimulation of pain receptors
THERMAL
* extreme heat or cold - tissue destruction; stimulation of thermosensitive pain receptors
CHEMICAL
* tissue ischemia - stimulation of pain receptors because of accumulated lactic acid and other chemicals and enzymes in tissues
* muscle spasm - tissue ischemia secondary to mechanical stimulation

Q

transmission

Q

perception

why clients may be reluctant to report pain

BOX 46-2 PAGE 1214

A
  • unwillingness to trouble staff who are perceived as busy

  • belief that others will think they are weak if they express pain
  • difficulty or inability to communicate their discomfort
  • concern about risks associated with opioid drugs (addiction)
  • concern about unwanted side effects, especially opioids
  • concern that use of drugs now will render the drug inefficient later in life
  • fear that reporting pain will lead to further tests or expenses
  • belief that nothing can be done to control pain
  • belief that enduring pain and suffering may lead to spiritual enlightenment

a condition that results from the undertreatment of pain where the client may become so focused on obtaining medications for pain relief that they become angry and demanding, “clock watch”, seem “drug seeking”

49
Q

Clients in Pain - culturally responsive care

A
  • respect clients as individuals - clients hold different beliefs about pain, inquire about the patient’s beliefs and ways to cope with pain
  • respect the client’s response to pain by - the patient has the right to respond to pain in the way they learned is appropriate, recognizing that expressions of pain vary widely and no expression is good or bad
  • recognize the variation within a culture by avoiding stereotyping an individual
  • expressions of pain vary between cultures and within cultures
50
Q
