Pharmacological and Non-Pharmacological Interventions for Pain Relief in Children
Pharmacological and Non-Pharmacological Interventions for Pain Relief in Children ( 28 Questions)
Which statement accurately describes the mechanism of action of opioids?
Opioids do not inhibit the synthesis of prostaglandins. Prostaglandins are chemicals that play a role in the perception of pain and inflammation, but opioids work through a different mechanism. They bind to opioid receptors in the body.
Opioids do not block the release of histamine. Histamine is involved in allergic reactions and inflammation, but it is not the primary target of opioids. Opioids primarily bind to opioid receptors.
No explanation
Opioids do not stimulate the central nervous system to reduce pain and inflammation. In fact, opioids often have a depressant effect on the central nervous system, leading to sedation and respiratory depression. Their main action is through binding to opioid receptors. The correct answer is choice C because opioids work by binding to opioid receptors, which alters the perception of pain. Opioid receptors are found in the central and peripheral nervous systems, and when opioids bind to these receptors, they modulate pain perception, leading to pain relief. This mechanism is how opioids exert their analgesic effects.
Choice A rationale:
Opioids do not inhibit the synthesis of prostaglandins.
Prostaglandins are chemicals that play a role in the perception of pain and inflammation, but opioids work through a different mechanism.
They bind to opioid receptors in the body.
Choice B rationale:
Opioids do not block the release of histamine.
Histamine is involved in allergic reactions and inflammation, but it is not the primary target of opioids.
Opioids primarily bind to opioid receptors.
Choice D rationale:
Opioids do not stimulate the central nervous system to reduce pain and inflammation.
In fact, opioids often have a depressant effect on the central nervous system, leading to sedation and respiratory depression.
Their main action is through binding to opioid receptors.
The correct answer is choice C because opioids work by binding to opioid receptors, which alters the perception of pain.
Opioid receptors are found in the central and peripheral nervous systems, and when opioids bind to these receptors, they modulate pain perception, leading to pain relief.
This mechanism is how opioids exert their analgesic effects.
