The nurse has administered an antipyretic agent to a client. What is the intended effect of this drug?
1. To stop inflammation
2. To reduce fever
3. To stop swelling
4. To block pain transmission
Correct Answer: 2
Rationale 1: An antipyretic has no direct impact on reduction of inflammation.
Rationale 2: Antipyretic agents reduce fever by acting directly on the hypothalamus heat-regulating center to produce peripheral vasodilatation, sweating, and dissipation of heat.
Rationale 3: An antipyretic agent has no effect on edema or swelling of tissues.
Rationale 4: Although antipyretic agents also can inhibit chemical mediators of pain, their mechanism is unclear.
Global Rationale: The goal of antipyretic therapy is to lower body temperature while treating the underlying cause of the fever, which is usually an infection. They have no direct impact on reduction of inflammation, edema, or blocking pain transmission. Some medications have more than one indication and could affect these parameters.
