Pain Flashcards
Pain
An unpleasant sensory and emotional experience associated with actual or potential tissue damage. Pain is a change in the nervous system, as well as being reflective of the patient’s past pain experiences and the meaning of pain.
What are the dimensions of pain?
cognitive, affective, physiologic, behavioral, sociocultural
Cognitive dimension of pain
Beliefs, attitudes, memories, and meaning attributed to pain that can influence the patient’s response to pain and should be incorporated into the comprehensive treatment plan
Affective dimension of pain
Emotional response to pain experience. Responses may include anger, fear, depression or anxiety. May be relieved by pain reflief and influenced by spirituality
Physiologic dimension of pain
Transmission of nociceptive stimuli that communicates tissue damage to the CNS
Behavioral dimension of pain
Observable actions used to express or control pain include facial expressions, social withdrawal, decrease in physical activity, use of relaxation and taking medications. Responses may also include fear, depression and anxiety
Sociocultural dimension of pain
Includes demographics, support systems, social roles, and culture. Age, gender, and education may influence beliefs and coping strategies. Sociocultural dimension of pain must be assessed without stereotyping
Narcotic Tolerance
This is the need for an increased dose to maintain the same degree of pain control. It is not as common as people think. If this develops the MD may choose to rotate drug instead of increasing the dose.
Physical Dependence
This is an expected response to ongoing exposure to pharmacologic agents manifested by withdrawal symptoms when blood levels drop abruptly. The drug should be tapered to avoid this barrier.
Addiction
This is a neurobiolgic condition where there is a drive to obtain and take substances for other than prescribed therapeutic value.
Endorphins
opiate-like peptides produced naturally by the body at neural synapses in the CNS which modulate the transmission of pain perception. They raise the pain threshold, produce sedation and euphoria.
Pain Threshold
The level that must be reached for an effect to be produced
Referred Pain
Pain that is perceived in an area distant from the site of the stimuli
Intractable Pain
Pain that continues to occur even with optimal medical management
Phantom Pain
A pain syndrome that occurs following surgical or traumatic amputation of a limb. The client experiences pain in the missing body part even though there is complete mental awareness that the limb is gone.
Somatic Pain
Pain arising from nerve receptors originating in the skin or close to the surface of the body
Visceral Pain
Pain arising from body organs, dull and poorly localized due to low number of nocipceptors
Neurogenic Pain
Also referred to as neuropathic pain. Arising from nerves
Gate Control Theory
Proposed by Ronald Melzack and Patrick Wall, gate control theory suggests that the spinal cord contains a neurological “gate” that either blocks pain signals or allows them to continue on to the brain. Unlike an actual gate, which opens and closes to allow things to pass through, the “gate” in the spinal cord operates by differentiating between the types of fibers carrying pain signals. Pain signals traveling via small nerve fibers are allowed to pass through, while signals sent by large nerve fibers are blocked. According to this theory synapses in the dorsal horns act as a gate that closes to keep impulses from reaching the brain or open to permit impulses to ascend to the brain. Gate control theory is often used to explain phantom or chronic pain.
Gate Control Theory & Nursing
The Gate Control Theory is one approach that helps to explain how thoughts and emotions of an individual modify the perception of pain. Clinically, RNs can use this model to treat the underlying causes of pain with nursing interventions such as massage, heat, cold, imagery, distraction, empathy and support
Factors that can affect an individual’s perception of and reaction to pain
- Ethnic and cultural values
- Developmental stage
- Environment and support individuals
- Past pain experiences
- Anxiety and stress
- Pain barriers
Infant (1 Month to 1 Year) Pain Perception, Behavioral responses and TNIs
- Give a glucose pacifier.
- Use tactile stimulation. Play music or tapes of a heartbeat
Toddler (1 to 2 Years) Pain Perception, Behavioral responses and TNIs
- No formal concept of pain related to immature thought process and poorly developed body image
- Reacts as intensely to painless procedures as to ones that hurt, especially when restrained
- Intrusive procedures, such as temperatures are very distressing
- Reacts to pain with physical resistance, aggression, negativism, and regression
Preschool (3 to 5 Years)Pain Perception, Behavioral responses and TNIs
- Pain perceived as punishment for bad thoughts or behavior
- Difficulty understanding that painful procedures help them get well
- Cannot differentiate between “good” pain (as a result of treatment) and “bad” pain (resulting from injury or illness)
- Reacts to painful procedures with aggression and verbal reprimands, e.g., “I hate you.” “You’re mean.”
- Distract the child with toys, books, pictures.
- Involve the child in blowing bubbles as a way of “blowing away the pain.”
- Hold the Child to provide comfort
School-Age Children (6 to 10 Years) Pain Perception, Behavioral responses and TNIs
- Reaction to pain affected by past experiences, parental response, and the meaning attached to it.
- Better able to localize and describe pain accurately
- Pain can be exaggerated because of heightened fears of bodily injury, pain, and death
- Provide a behavioral rehearsal of what to expect and how it will look and feel.
Adolescent (11 to 18 Years) Pain Perception, Behavioral responses and TNIs
- Can locate and quantify pain accurately and thoroughly
- In general, highly controlled to responding to pain and painful procedures; brave in front of peers and not report pain
- Provide opportunities to discuss pain.
- Provide privacy.
- Present choices for dealing with pain. Encourage music or TV for distraction.
Adult Pain Perception, Behavioral responses and TNIs
- Behaviors exhibited when experiencing pain may be gender-based behaviors learned as a child.
- May ignore pain because to admit it is perceived as a sign of weakness of failure.
- May use pain for secondary gain, for example, to get attention.
- Deal with any misconceptions about pain.
- Focus on the patient’s control in dealing with the pain.
- Allay fears and anxiety when possible.
Elder Pain Perception, Behavioral responses and TNIs
- May perceive pain as part of the aging process.
- May have decreased sensations or perceptions of the pain.
- Lethargy, anorexia, and fatigue may be indicators of pain.
- May withhold complaints of pain because of fear of the treatment, of any lifestyle changes that may be involved, or of becoming dependent.
- May describe pain differently, that is, as “ache,” “hurt,” or “discomfort.”
- May have chronic pain which often results in depression, sleep disturbance, decreased motility, and social isolation
Pain Assessment
pattern, area, intensity, nature
Pain Pattern
How pain changes with time, its onset, and duration
Pain Area
Place on the body where pain is felt. helps provider to identify cause and treatment of pain. same as location of pain.
Pain Intensity
Amount of pain felt, rated using pain scales
Pain Nature
How the pain feels to the patient. The quality of pain, sharp, aching, burning, experiences such as anxiety, depression and fatigues can worsen nature of pain
Define Pain Pattern
Describes how the pain changes with time, activity or other factors. Refers to factors that increase or relieve pain
Examples of pain pattern desciptors
- Continuous, steady, constant
- Rhythmic, periodic, intermittent
- Brief, momentary, transient
Visual Analog Scale
Ask patient to place a mark on a line that best describes amount of pain. With a centimeter ruler, measure from “no pain” end of the scale to the patient’s mark and record centimeter number of the measurement of pain intensity. Example: “Patient has a 2.5 cm measurement of pain at 8 am.” At 10 am patient had a measurement of 3 cm pain. The pain would be worse at 10 am. Use with all patients age 5 or older.
Numeric Rating Scale
Explain to patient that at one end of the line is zero which means no pain. At the other end is ten which means worst possible pain. Ask patient to choose a number that best describes own pain. Use with all patients age 4 1/2 and older.
Wong FACES Pain Rating Scale
Can be used with children starting at age 3. Point to a face that best describes patient pain.
FLACC Scale
This scale is used to assess pain levels in cognitively impaired patients including patients recovering from anesthesia and children ages 2 months – 7years.
FLACC Score 0
No particular expression or smile, normal position or relaxed, lying quietly, normal position, moves easily, no cry awake or asleep, content, relaxed
FLACC Score 1
occasional grimace or frown, withdrawn, disinterested, uneasy, restless, tense, squirming, shifting back and forth, tense, moans or whimpers, occasional complaint, reassured by occasional touching, hugging or being talked to, distractible
FLACC Score 2
frequent to constant quivering chin, clenched jaw, kicking or legs drawn up, arched, rigid or jerking, crying steadily, screams or sobs frequently, frequent complaints, difficult to console or comfort
To use FLACC Scale
Assess each of the categories in the far left column to obtain a score of 0-2 then
Add the scores for all five categories to obtain a score of 0-10.
Behavioral Assessment
Behavioral assessments are important. Many individuals who are experiencing pain show it either by verbal complaints or nonverbal behaviors.
Nonverbal Facial Expressions Indicating Pain
Clenched teeth Wrinkles forehead Biting lips Scowling Closing eyes tightly Widely opened eyes or mouth
Nonverbal Vocalizations Indicating Pain
Crying Moaning Gasping Groaning Grunting

World Health Organization Three Step Analgesic Ladder
The World Health Organization Three Step Analgesic Ladder is a guide to selecting the initial analgesic level and dosing. The ladder presents a treatment model for pain where treatment gets more aggressive the further up the ladder you go. Continued reassessment is needed to modify the treatment plan based on the patient’s response.
World Health Organization Mild Pain
1-3 on scale. Nonopiod medication with an adjuvant medication if the patient has neuropathic pain
World Health Organization Moderate Pain
4-6 on scale. Opioid medication in low dose is added with the nonopioid and adjuvant medication continued
World Health Organization Severe Pain
7-10 on the scale. Higher doses of the opioid, nonopiod and adjuvant medications are continued. When a patient presents with severe pain ordered medications are prescribed at the appropriate level for that patient’s pain
What is the limitation of the World Health Organization’s three step analgesic ladder?
The misconception that mild to moderate pain opioids, such as codeine, must be used in step three. It is recommended that smaller doeses of strong opioids, such as morphine, are just as effective and preclude having to switch medications at a later time
TNIs for Acute and Chronic Pain
- Assess whether patient is experiencing pain at the time of the interview. If so, provide appropriate interventions to provide pain reflief. Assess patient’s pas experiences with pain and effectiveness of methods used to manage pain, including experiences with side effects, typical coping responses, and how they express pain on initial interview
- Teach patient to report pain location, intensity, using a pain rating scale and quality when experiencing pain. Find out about patient’s pain reaction, pain threshold, and pain tolerance
- Determine patient’s current medication use
- Administer ordered pain medications. It is important to use the least invasive route of administration capable of providing adequate pain control. Oral is the route of choice with a functioning GI tract
Pain Reaction
the autonomic nerous system and behavioral responses to pain
Pain Threshold
Intensity of the noxious stimuli necessary for the individual to perceive pain
Pain Tolerance
Duration of time of the intensity of which an individual accepts a stimulus above the pain theshold becaore making a verbal or overt pain response
When is around the clock pain medication especially helpful?
24-48 hours after surgery
What would you administer for acute pain?
opioids po or iv
What would you administer for chronic pain?
opioids po
What types of medications are considered for chronic pain?
adjuvant medications that are analgesic may be considered in combination to allow for lower dosages of individual medications
What route is avoided for pain management?
IM route because of unreliable absorption, pain, and inconvenience
What route is preferred for rapid control of severe pain?
IV
For ongoing, chronic pain, what would you give?
analgesic around the clock
What would you give for intermittent pain?
prn dosing
What would you assess with opioids?
pain intensity, sedation, RR & status, constipation, N/V, urinary retention.
Opiods may cause what?
resp. depression because they reduce the responsiveness of carbon dioxide chemoreceptors located in the resp. centers of the brain
What should you discuss with a patient on pain medications and experiencing pain?
fears of undertreated pain, addiction, and overdose. Opioid tolerance and physical dependence are expected with long term use of opioids from chronic pain and should not be confused with addiction which is extremely rare for patients using opioids for pain relief
When should you reassess effectiveness of IV analgesics?
30 minutes after IV administration
When should you reassess effectiveness of po analgesics?
1 hour
Key Components of Documentation for pain
- description of pain - use patient’s own words
- location
- intensity
- quality
- radiation
- time of onset
- factors that aggravate pain
- factors that relieve pain
- methods used to promote comfort
- patient’s response
Patient/Family Teaching Pain
Provide written materials on pain control
Explain pain assessment process and purpose of the pain rating scale.
Teach patient to use the pain rating scale to rate intensity of past or current pain
Demonstrate medication administration and use of supplies and equipment. If PCA is ordered, determine patient’s ability to press appropriate button. Remind patients and staff that the PCA button is for patient-only use.
Reinforce importance of taking pain medications to keep pain under control.
Demonstrate use of appropriate nonpharmacological approaches for controlling pain such as heat, cold, distraction techniques, relaxation breathing, visualization, rocking, stroking, music, and television.
Guidelines for Assessment and Treatment of Acute and Chronic Pain After Surgery
- Focus on prevention or control.
- Accept patient’s report of pain level and act on it accordingly.
- Differentiate the types of pain. Assess and document acute pain and chronic pain separately so you can see which aspect of the pain experience is more problematic.
- Research shows that around-the-clock administration of pain medication is more effective than PRN.
- Do not make the mistake of using behavioral or vital signs to judge the patient’s pain. A patient with chronic pain may not look or act in pain and probably will not have elevations in blood pressure or pulse rate that you assess with someone with acute pain.
- Select the smallest dose to provide effective pain control with fewest side effects.
What are the negatives of pain?
effects quality of life; it interferes with ADL’s, prevents relaxation and sleep; increases anxiety, depression, stress and fatigue
Cancer Acute Pain
severe and lasts a short time….surgical incision
Cancer Chronic Pain
pain that lasts for a long time. those with chronic cancer pain may also experience breakthough pain, a transient increase in pain that exceeds the level managed by pain medication used on a continuous basis.
Somatic Cancer Pain
commonly arises from metastases from the bone and pain r/t surgery. It is localized and described as stabbing, throbbing, dull, or aching
Visceral Cancer Pain
common in pancreatic cancer as well as patient with metastasis to the abdomen. Described as pressure like cramping, gnawing, or squeezing. Some patients may experience referred pain as a result of visceral pain
Neuropathic Cancer Pain
may result from a tumor compressing or infiltrating the nerves or spinal cord. It can also result from chemical damage to the nervous system by cancer treatment. It is typically described as sharp, burning, or shooting and is often accompanied by numbness and tingling. Patient may also report allodynia (pain provoked by normal non-painful stimulus such as light touch).
TNIs for Cancer-Related Pain
Confirm that sufficient ATC and PRN analgesics are ordered and available.
Make certain that the clients can obtain prescribed analgesics at their usual pharmacy or that an alternate source is found.
Instruct clients receiving chronic opioid therapy to carry written documentation of their current analgesic regimen (drug, dose, frequency, and route) and treating physician (with phone number) when leaving their home. This information can be essential should an emergency arise.
Be aware of the analgesic effect of corticosteroids. If they are tapered, it may necessitate increasing opioids to provide the same analgesia. Also, the reverse may be true; if steroids are added, it may be necessary to decrease the opioids administered to prevent side effects.
Increasing pain or decreasing analgesic effectiveness, without change in analgesic regimen, frequently means advancing diseases, not tolerance. Additional assessment of the cause of pain is necessary. This may result in diagnosis of treatable conditions.
As cancer progresses, continually assess whether pain is being controlled and the patient is satisfied with the method of control.
Avoid the IM route. Consider the use of an indwelling subcutaneous needle should repeated injections become necessary.
Educate the client and caregiver to identify situations that require professional intervention (e.g., unrelieved pain, acute changes in severity, location, or duration of pain, or unrelieved complications of the pain management regimen).
Understand that the use of morphine, methadone, or the IV route may have special meaning to a client or family. For example, use of morphine or the IV route may be interpreted that the client is close to death when in fact the client may not be, or the use of methadone may be interpreted that the client is a drug addict when in fact methadone may be an effective analgesic for that particular client.
Individuals with chronic cancer-related pain who experience acute pain episodes (such as surgery) will need continued treatment of their chronic cancer-related pain in addition to treatment of the acute pain.
Be aware of a client’s goals of care. Goals of care an include any one or combination of the following: maximizing survival, maximizing function, and maximizing comfort. Knowledge of goals of care is necessary when evaluating the risk/benefit ratio of pain treatments. For example, in an opioid-naive, fragile client whose only goals is to maximize survival, it may be necessary to limit the use of opioids. In the dying client, it may not be possible to maximize function and comfort. A decision will need to be made as to what the primary goal is to ensure appropriate treatment.
Some health care professionals mistakenly believe that if a cancer client is dying, the opioid used for pain relief should be changed to morphine. This is not necessary as long as the prescribed analgesic controls the pain without dose-limiting side effects.
Be very cautious about the use of naloxone (Narcan) in opioid-tolerant clients. Be aware of the goals of care. Rule out progression of disease and other medications as the cause of deteriorating respiratory status. If administration of naloxone is appropriate, administer slowly, titrating to effect to avoid precipitating withdrawal and severe pain.
Inpatient Cancer Pain Teaching
- Instruct clients on admission to send home any analgesics they may have brought with them.
- Early on if a possibility exists that the client will be discharged or transferred with a PCA pump, epidural catheter, or other high-tech analgesic intervention, evaluate client’s home situation and insurance coverage to determine whether this will be a safe and insurance-covered situation.
Home Care Cancer Pain Teaching
- Encourage client and/or caregiver to use a pain control record to keep track of medication use, especially use of PRN doses and pain ratings after pain relief measures.
- Encourage client and/or caregiver to notify primary physician that medication supply is getting low in enough time to have prescriptions renewed without an interruption in analgesic regimen. It is often a good idea to have a separate 3-day to 4-day supply kept for use in emergencies.
- Consider the need for parenteral medications in the home, and identify and educate the caregiver who could administer this medication should the need arise. Make sure that the client and caregiver know who is to be contacted should a situation arise that requires professional intervention. This should cover situations arising 24 hours a day, 7 days a week.
Emergency Department Cancer Pain Teaching
- Quickly identify the extent of disease, goals of care, DNR status, and present analgesic regimen (especially specific analgesic use and effectiveness in the last 48 hours). Is this client opioid naive or tolerant? Has this client been able to take analgesics by the route prescribed?
- Be very cautious about the use of naloxone (Narcan).
