What is breakthrough pain?
A temporary flare-up of pain despite ongoing pain management.
63
What is incident pain?

64
What is the most reliable indicator of pain?

What is the best way to assess pain in a nonverbal patient?
Observing facial expressions, body movements, and vital signs.
67
What are common barriers to pain management?
Fear of addiction, inadequate provider knowledge, and cultural differences.
68
How can nurses advocate for better pain management?
By educating patients, using appropriate pain scales, and ensuring timely medication administration.

What is the first step in pain transmission?
Transduction, where a noxious stimulus is converted to an electrical impulse.
70
What is the function of prostaglandins in pain?
They increase sensitivity to pain and promote inflammation.
71
Where does pain transmission occur?
From the peripheral nerves to the spinal cord and then to the brain.
72
What part of the brain perceives pain?
The cerebral cortex.
73
How does modulation help control pain?
