Pain Flashcards

Q

what is pain?

A

*“Whatever the experiencing person says it is, existing whenever the
experiencing person says it does” (pg. 1233-1234).
*Human body’s defensive mechanism that indicates the person is
experiencing a problem.
*Physical suffering or discomfort, unpleasant sensory, emotional experience
*Chronic pain is the most common reason to seek healthcare
*Linked to restrictions in mobility and daily activities, dependence on opioids, anxiety and
depression, and poor perceived health or reduced quality of life
*Fifth vital sign
*According to the AMA, gives pain equal status with blood pressure, heart rate,
respiratory rate and temperature as vital signs. Consider assessing your patient’s pain
once V/S are taken and documented.
*Relief of pain is a client rightGreat resource:

Q

peripheral nervous system

A

*Composed of sensory and motor neurons
*Pain perceived through sensory neurons
*Responded to through motor neurons
*Connections occur within spinal cord
*Nociceptors located at ends of small afferent neurons
*All tissues except brain
*Especially numerous in skin, muscles

Q

the pain process

A

*Transduction: activation of pain
receptors
*Transmission: conduction along
pathways (A-delta and C-delta fibers)
*Perception of pain: awareness of the
characteristics of pain
*Modulation: inhibition or
modification of pain

origin of pain

A

Physical: cause of pain can be identified
Psychogenic: cause of pain cannot be identifiedHeadaches, back pain, stomach pain
Referred: pain is perceived in an area distant from its point
of originPain associated with a heart attack is often referred to the chest, arms, neck or
shoulders.
Pain from a gallbladder attack may be felt in the back of the shoulder.

Q

gate control theory of pain

A

Proposed by Melzack and Wall, 1965Most widely accepted pain theory; most practical
*Describes the transmission of painful stimuli and recognizes a
relationship between pain and emotions.
*Small- and large-diameter nerve fibers conduct and inhibit pain
stimuli toward the brain.
*Gating mechanism determines the impulses that reach the brain.
*Other factors that have impact of this gate are past experiences,
the cultural and social environment, personal expectations,
beliefs about pain and etc.
*Factors that control gates: physical, emotional and behavioral
(responses to pain). See Box 35-1

Q

A patient who has bone cancer is most likely
experiencing which of the following types of pain?

A

somatic Rationale: Deep somatic pain is diffuse or scattered and originates
in tendons, ligaments, bones, blood vessels, and nerves.
Cutaneous pain usually involves the skin or subcutaneous tissue.
Visceral pain is poorly localized and originates in body organs.
Referred pain is pain that originates in one part of the body and is
perceived in an area distant to that part.

Q

perception of pain

A

Pain thresholdPain tolerance is the maximum level of pain that a person is able to
tolerate.
*Regular exposure to painful stimuli will increase pain tolerance
*Pain tolerance is distinct from pain threshold (the point at which
pain begins to be felt)
AdaptationLeads to protection of pain or injury
Modulation of painNeuromodulators
*Endorphins, dynorphins, enkephalins

Q

osteoarthritis

A

Osteoarthritis (OA)
A degenerative joint disease that is the most common chronic condition of the joints
Effects about 31 million Americans
50,000 children in the United States have OA: Juvenile rheumatoid arthritis most common
Often referred to as “wear and tear”
Occurs when the cartilage or cushion between joints breaks down leading to pain,
stiffness and swelling.
Most effected parts of the body:
Hips
Knees
Fingers
Feet

76
Q

OA symptoms

A

Symptoms:Pain and stiffness (most common)
*Affected joints may get swollen; particularly after lots of activity
*Limited range of motion depending on where its located
*Clicking or cracking sound
*Fatigue
*Tenderness
*Bone spurs on imaging

77
Q

OA risk factors

A

*Risk Factors:
No specific cause
Women; although not clear why
>45 years of age
Rare in children
Factors that lead to OA:
*Obesity (BMI)
*Injury (fractures, ligament tears)
*Overuse (athletes)
*Family history
*Diabetes

78
Q

OA examination and diagnosis

A

OA Examination & Diagnostics
Diagnosis after healthcare examination
*Assessing for range of motion, tenderness, signs and symptoms of joint damage
*PMH and risk factors
Diagnostic tests
*Joint aspiration-insertion of needle into joint for fluid to assess for crystals or joint
deterioration
*X-ray-can help show any damage to the joints or bone spurs
*MRI-obtains a better view of the cartilage and other joint structures
https://www.mayoclinic.org/diseases-conditions/osteoarthritis/symptoms-causes/syc-20351925
If the cartilage wears down completely, bone will rub on bone.

79
Q

OA treatment

A

No cure
*Manage symptoms (pain)
*NSAIDS
*Analgesics
*Corticosteriods
*Hyaluronic acid. Occurs naturally in joint fluid, acting as a shock absorber and lubricant. However, the acid appears to
break down in people with osteoarthritis. The injections are done in a doctor’s office.
*Duloxetine (Cymbalta) Typically used as an antidepressant, but approved to help treat chronic pain, including
osteoarthritis pain.
*Nonpharmocological approach- massage, acupuncture, vitamins, relaxation techniques
*Improve joint mobility (physical activity)
*Weight management
*Stretching
*Surgery
*joint surgery can repair or replace severely damaged joints, especially hips or knees.
*PT/OT
*Tens Unit-provides some short term relief

80
Q

postsurgical pain overview

A

*“Post-Op” pain: response to tissue trauma during surgery
*“Post Surgical” Refers to both inpatient and outpatient patients
*Post-op pain typically lasts 4-6 weeks. This can vary depending on the type of surgery
*Length of stay also varies (type of surgery, pain control, complications, etc)
*Post Anesthesia Care Unit (PACU)
*Holding area for patients after their procedure
*Important to monitor safety- Side rails need to be up and bed in low position. Bed alarm should also be
