A nurse is providing education to the parents of a child who will be receiving acetaminophen (Tylenol) for pain relief.
Which statement by the nurse accurately describes the mechanism of action of acetaminophen?
"Acetaminophen works by inhibiting the synthesis of prostaglandins, which helps reduce pain and fever.”..
"Acetaminophen works by blocking the release of histamine, which helps reduce pain and fever.”..
"Acetaminophen works by increasing the production of endorphins, which helps reduce pain and fever.”..
"Acetaminophen works by stimulating the central nervous system, which helps reduce pain and fever.”..
The Correct Answer is A
Choice A rationale:
Acetaminophen, also known as Tylenol, works by inhibiting the synthesis of prostaglandins, which helps reduce pain and fever.
Prostaglandins are chemicals produced by the body in response to injury or illness and are known to promote inflammation, pain, and fever.
By inhibiting the synthesis of prostaglandins, acetaminophen reduces these symptoms.
Choice B rationale:
This option is not correct.
Acetaminophen does not work by blocking the release of histamine.
Histamine is a chemical that plays a role in allergic reactions and inflammation, but it is not the primary target of acetaminophen.
Choice C rationale:
This option is not correct.
Acetaminophen does not increase the production of endorphins.
Endorphins are natural painkillers produced by the body, but acetaminophen's mechanism of action is related to prostaglandin inhibition.
Choice D rationale:
This option is not correct.
Acetaminophen does not stimulate the central nervous system.
Its primary action is the inhibition of prostaglandin synthesis in peripheral tissues.

Correct Answer is A
Explanation
I am willing to try guided imagery exercises.”..
Choice A rationale:
It is essential for the client to express willingness to try non-pharmacological interventions like guided imagery.
This shows the client's open-mindedness and readiness to explore alternative methods for pain relief.
Guided imagery can be effective in managing chronic pain by focusing the mind on positive mental images, helping to reduce pain perception and promote relaxation.
Choice B rationale:
Expressing disbelief in alternative methods may hinder the client's ability to benefit from non-pharmacological pain relief interventions.
A negative attitude towards these methods can create resistance and limit their effectiveness.
Choice C rationale:
Requesting pain medication instead of trying non-pharmacological interventions immediately may not be the most appropriate response, as it bypasses the opportunity to explore alternative pain management strategies.
Pain medications may have side effects and may not be the most suitable first-line treatment for chronic pain.
Choice D rationale:
Expressing a lack of time for non-pharmacological interventions dismisses the potential benefits of guided imagery or other methods.
It is essential for the client to be open to trying various strategies to effectively manage their chronic pain.

Explanation
Choice A rationale:
Aromatherapy is a non-pharmacological intervention that can help provide pain relief.
Aromatherapy involves the use of essential oils, and certain scents can have a calming and pain-relieving effect.
Choice B rationale:
Distraction techniques, such as engaging in activities or conversations that divert the patient's attention from pain, can be effective in providing pain relief.
These techniques can help reduce the perception of pain.
Choice C rationale:
Heat therapy, such as the application of warm compresses or heating pads, is a non-pharmacological intervention that can provide pain relief.
Heat can help relax muscles, increase blood flow, and reduce pain, especially in cases of muscle or joint discomfort.
Choice D rationale:
Cold therapy is not typically used for pediatric patients experiencing pain.
While cold therapy can be effective for certain conditions, such as reducing inflammation and swelling, it may not be as well-tolerated by children.
Choice E rationale:
Massage therapy is another non-pharmacological intervention that can help relieve pain in pediatric patients.
Massage can promote relaxation, improve circulation, and reduce muscle tension, leading to pain relief.
These interventions offer a comprehensive approach to pain management in pediatric patients, taking into account individual preferences and the nature of the pain.
