Additional Assessments Flashcards
- pain assessment - nutrition assessment - violence assessment
Pain Perception
pain is a highly complex and subjective experience
- it can originate from the PNS, CNS, or both
- if the patient says they have pain, they have pain –> SUBJECTIVE
Nociceptors
located in he skin, connective tissue, muscles, and thoracic, abdominal and pelvic viscera
- identify and transmit pain stimuli to the CNS
Older Adults: Experience of Pain
older adults experience pain the same way everyone else does
–> pain IS NOT a normal aging process, it is indicative of an underlying disease or condition
Sources of Pain
- Nociceptive Pain
a. Somatic Pain
b. Visceral Pain - Neuropathic Pain
Nociceptive Pain
pain caused by tissue injury
- well localized
- often described as throbbing, or
aching
Somatic Pain
Superficial - pain derived from superficial tissues and/or cutaneous tissues
Deep - pain derived from joints, tendons, muscle or bone
- often easier to identify exact locations
Visceral Pain
pain originating from larger interior organs
- can be constant or intermittent
- poorly localized/ referred to another
area
Neuropathic Pain
pain originating from a lesion or disease of the nervous systems
- not well localized (may refer)
- described as burning, shooting,
lancing pain
- intensifies at night (no more stimuli to
distract)
Referred Pain
pain that originates at one location but is experienced at another
spinal nerves share pathways, thus pain along the nerve is experienced at the locations the nerve inervates –> brain cannot differentiate point of origin
Types of Pain (duration)
- Acute
- Chronic
Acute Pain
short term (3-7 days)
- follows a predictable trajectory –>
pain dissipates when injury heals
- serves a purpose - warns of actual or
potential tissue damage
unrelieved acute pain can lead to persistent (chronic) pain through peripheral and central sensitization
- increase in sensitivity of nociceptors to
stimuli that normally would not elicit
pain
Chronic Pain
long term, persistent (3+ months)
3 potential causes:
1. malignant - cancer related (worsens
with the progression of the disease)
2. non-malignant - not cancer related
(often musculoskeletal)
3. neuropathic - lesion or disease of the
somatosensory nervous system
Pain Behaviour: Acute
high risk of undertreatment
- cognitively intact but non-verbal
- use pain assessment tools + body
language to determine pain
Pain Behaviour: Chronic
high risk of under-detection
- have adapted to the pain
- understand patient’s perspective of
pain (what does it feel like, how is this
compared to your normal pain)
Pain Behaviour: Unconscious Patient
high risk of under-detection AND under treatment
- not cognitively intact and nonverbal
- unable to use body language, verbal
communication, or normal pain
assessment tools
use specialized tools + vital signs to detect pain
- patients will still experience pain when
unconscious
PQRSTUV
pain assessment
P - palliative/ provocative
Q - quantity/ quality
R - region/ radiation
S - severity (scale of 1-10)
T - timing (onset, consistency of pain)
U - understand the patient + their
understanding of pain
V - vitals
