Step-by-step explanation:
The primary health care provider is most likely to prescribe acetaminophen for a 65-year-old patient experiencing mild musculoskeletal pain. Acetaminophen, also known as Tylenol, is a type of pain medication that has a relatively low risk of serious side effects when taken as prescribed. If acetaminophen does not provide adequate pain relief, non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen may be prescribed. NSAIDs, however, have a higher risk of serious side effects compared to acetaminophen.
