What is one key challenge in assessing pain in non-verbal patients?
Reliance on non-verbal indicators like facial expressions or body movements.
61
What is nociception?
The body’s normal response to painful stimuli.
62
What is the role of prostaglandins in pain?
They contribute to inflammation and increase sensitivity to pain.
63
Why is untreated pain problematic?
It can lead to complications such as immobility, respiratory issues, and depression.
64
What is the first-line treatment for mild pain?
Nonopioid analgesics (NSAIDs, acetaminophen).
65
What is the main risk associated with long-term NSAID use?
Gastrointestinal bleeding and kidney damage.
66
What is the preferred route for opioid administration?
Oral, unless rapid relief is needed.
67
What is the main disadvantage of IM opioid injections?
Painful administration and unpredictable absorption.
68
What is a common side effect of opioid analgesics?
Constipation.
69
What is the benefit of patient-controlled analgesia (PCA)?
Allows patients to self-administer opioids within preset limits.
70
Why should opioid-naïve patients be monitored closely?
They have a higher risk of respiratory depression.
71
How does fentanyl differ from morphine?
Fentanyl is more potent and has a rapid onset.
72
What is an advantage of the fentanyl transdermal patch?
Provides continuous pain relief for chronic pain conditions.
73
Why should fentanyl patches be used cautiously in fever patients?
Heat increases absorption, leading to overdose risk.
74
What is equianalgesia?
The concept of comparing opioid doses to achieve equal pain relief.
75
Why is methadone used for opioid addiction treatment?
It has a long half-life and reduces withdrawal symptoms.
76
What is the role of naloxone (Narcan)?
It reverses opioid overdose effects.
77
What is the ceiling effect in nonopioids?
Increasing the dose beyond a certain point does not improve pain relief but increases side effects.
78
What are adjuvant analgesics?
Medications that enhance pain relief but were not originally developed for pain (e.g., antidepressants, anticonvulsants).
