Break-through pain
Pain that occurs before the expected duration of a specific analgesic is known as what?
End-of-dose failure
When end-of-dose failure occurs, what is usually the next step?
A change in dose or scheduling

C: consolability
Assessing the associated symptoms of pain can provide what type of information?
Any aggravating symptoms that increase the pain or make pain better
Why is it important to assess a patient’s belief, expectations, and goals with pain management?
Knowing how a patient views pain, their own expectations of pain, and what their particular goals can help ensure there is successful pain management
- Can also let you know if you need to educate pain on whether their expectations and goals of pain management are appropriate and reachable
What are the 9 principles of pain assessment and management?
- Patient have right to appropriate assessment and pain management
- Pain is always subjective
- Physiologic and behavioral signs are not reliable or specific for pain
- Assessment approaches must be appropriate for the patient population
- Pain can exist even when no physical cause can be found
- Different patients have different levels of pain in response to comparable stimuli
- Patients with chronic pain may be more sensitive to pain and other stimuli
- Acute pain that is not adequately controlled can result in physiologic changes that increase the chance of developing persistent pain
What are important factors to keep in mind with pain assessment in nonverbal patients?
- Obtain self-report when possible
- Never assume nonverbal persons are unable to communicate
- Observe for behaviors that can indicate pain
- Obtain surrogate reports of pain from professional and family caregivers
- Try to use analgesics and reassess patient to observe for decrease in pain-related behaviors
What are some ways a nonverbal patient can communicate?
Blinking, hand gestures, writing
What are some behaviors you can observe in a nonverbal patient that may be indicative of pain?
- Grimacing
- Frowning
- Rubbing a painful area
- Groaning
- Restlessness
What are some barriers to pain management?
- Fear of addition: uncommon in pts taking opioids as directed by HCP team
- Fear of tolerance: normal physiologic response, drug can be changed
- Concerns of side effects: teach that some side effects decrease w/ time, can also start therapy to prevent certain side effects @ same time as opioid (i.e, constipation)
- Forgetting to take analgesic: pain containers, start regimen, use methods for record keeping
- Economic Status: ability to afford medication, have access to medication, etc.
What are some important factors to remember when providing pain management in patients with a history of substance abuse?
- Patients may be reluctant to take opioid analgesics or may require stronger doses
- Stress of unrelieved pain may contribute to relapse in recovery or increase drug use in actively using pts
- When patient’s acknowledge substance abuse:
- Determine types and amounts of drugs used, avoid these
- Use single opioid to avoid withdrawal symptoms
- Be aware of own attitude about people w/ substance abuse
What are the common Non-opioid medications for pain management?
- Acetaminophen
- Aspirin
- NSAIDS
What are some important factors to know regarding Non-opioid medications?
- Have analgesic ceiling
- No physical tolerance or dependence
- Available without prescription
- Allow for lower dosing of opioid when used in conjunction (opioid-sparing effect)
Non-opioids are said to have analgesic ceilings. What does this mean?
Increasing the dose beyond the safe limit doesn’t produce a greater analgesic effect
NSAIDS have been linked to higher risks for what?
Cardiovascular events:
Myocardial Infarction, stroke, etc.
Non-opioid medications for pain management: Salicylates
Aspirin
- Used for mild to moderate pain, antiplatelet
- Common side effects: increased risk for bleeding (GI in particular)
Non-opioid medications for pain management: Acetaminophen
- Mild to moderate pain, antipyretic
- NO antiplatelet or anti-inflammatory effects
- Metabolized by liver: chronic dosing of more than 3g/day, acute overdose, or patient’s w/ severe liver disease can lead to Hepatoxicity
Non-opioid medications for pain management: NSAIDs
Naproxen, Ibuprofen, Celecoxib, Dicoflenac
- Mild to moderate pain, anti-inflammatory properties
- Side effects: GI: irritation, ulceration, hemorrhage, toxicity
- Don’t give to patient’s w/ hx of PUD, 65+, using corticosteroids, anticoagulants
What type of medications are used when pain levels exceed 7
Opioids
What are side effects common to opioid use?
- Constipation
- N&V

A patient with opioid use is experiencing respiratory depression and sedation. What are some priority interventions?
- Vigorously stimulate to keep the patient awake
- Apply oxygen to patient
- Administer naloxone
Adjuvant medication is more effective for what type of pain?

What response am I in the inflammatory response?
- Brief moment of vasoconstriction followed by release histamine and other chemical mediators → leading to vasodilation.
- Increased capillary permeability caused by chemical mediators lead to movement of fluid from capillaries into tissue spaces
A. Vascular
B. Cellular
A: Vascular
In the vascular response of the inflammatory response, what releases chemical mediators and what is the body’s response?
- Injured cells release chemical mediators, triggering the vascular response
- Responsible for many of the signs of inflammation
- Redness
- Heat
- Swelling @ site of injury and surround area
What response am I in the inflammatory response?
Neutrophils and monocytes migrate to the site of injury to engulf bacteria and breakdown inflammatory debris
A. Vascular
B. Cellular
B. Cellular
Which type of WBC am I?
- First WBC to arrive (usually 6 to 12 hrs)
- Role: engulf bacteria, foreign material, damaged cells
- Accumulation leads to pus due to short life span
Neutrophils

Bands
When there is an increased level of bands, this is known as what?
A shift to the left
A shift to the left is most commonly seen in what?
ACUTE bacterial infections
What type of WBC am I?
- Arrive to injury site 3-7 days after initial injury
- Can stay days to weeks
- Transform into macrophages once in tissue space and breakdown inflammatory debris
A patient’s WBC count shows elevated neutrophils. What information can this provide about the infection?
It is relatively new
