A client with acute joint inflammation tells the nurse, "I've been taking acetaminophen as ordered on the bottle, but my swelling and inflammation don't seem to be getting better." What should the nurse teach the client?

A. "Acetaminophen has no effect on inflammation.": Acetaminophen is an analgesic and antipyretic, but it lacks anti-inflammatory properties. It helps relieve pain and reduce fever, but it does not reduce joint swelling or inflammation, making it less suitable for conditions like arthritis. B. "Acetaminophen's only clinical use is for pain treatment.": Acetaminophen also has antipyretic (fever-reducing) effects. While it is not anti-inflammatory, it does have multiple clinical uses beyond pain relief, especially in febrile illnesses. C. "It takes some people a few weeks to feel a difference.": This applies more to NSAIDs or disease-modifying agents in inflammatory conditions. Acetaminophen provides relatively fast relief from pain but does not improve inflammation over time, regardless of duration of use. D. "Keep taking it as ordered, and watch for any signs of bleeding.": Bleeding risk is not commonly associated with acetaminophen. Unlike NSAIDs or aspirin, acetaminophen does not significantly affect platelet function or gastric mucosa.
