A nurse is caring for a client who has been experiencing muscle tension and discomfort. The nurse decides to use heat therapy as part of the client’s care plan.
Which of the following outcomes should the nurse anticipate?

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.

Choice A rationale:

Fentanyl is a nonsteroidal anti-inflammatory drug (NSAID) that reduces inflammation and pain.

This statement is incorrect.

Fentanyl is not an NSAID.

It is an opioid medication that binds to opioid receptors, altering the perception and response to painful stimuli.

It is used for severe pain management and is unrelated to NSAIDs.

Choice B rationale:

Fentanyl is an opioid medication that binds to opioid receptors, altering perception and response to painful stimuli.

This is the accurate response.

Fentanyl is a potent opioid that works by binding to opioid receptors in the central nervous system, altering the perception of pain and the body's response to painful stimuli.

It is a powerful analgesic for severe pain.

Choice C rationale:

Fentanyl is similar to Acetaminophen and Ibuprofen but is typically used for more severe pain.

This statement is misleading.

Fentanyl is not similar to Acetaminophen or Ibuprofen.

While all three medications have pain-relieving properties, Fentanyl is a much stronger opioid used for severe pain, while Acetaminophen and Ibuprofen are milder, non-opioid analgesics.

Choice D rationale:

Fentanyl works by inhibiting prostaglandin synthesis, similar to Acetaminophen and Ibuprofen.

This statement is inaccurate.

Fentanyl's mechanism of action is different from Acetaminophen and Ibuprofen.

While Acetaminophen and Ibuprofen inhibit prostaglandin synthesis, Fentanyl acts by binding to opioid receptors and modulating pain perception centrally, without affecting prostaglandins.
