Final answer:
NSAIDs work by blocking COX-1 and COX-2 to achieve pain relief.
Step-by-step explanation:
NSAIDs, like aspirin, work by blocking the COX-1 and COX-2 enzymes, which are involved in pain and inflammation. By inhibiting these enzymes, NSAIDs reduce the production of prostaglandins, which are responsible for causing pain and inflammation in the body. As a result, the primary effect achieved by blocking COX-1 and COX-2 is pain relief. The nursing instructor has explained that nonsteroidal anti-inflammatory drugs (NSAIDs) function by blocking the COX-1 & COX-2 enzymes, which play critical roles in the synthesis of prostaglandins that contribute to inflammation and pain. By inhibiting these enzymes, NSAIDs effectively reduce the production of prostaglandins, leading to relief of pain. It is important to note, though, that while NSAIDs are effective at pain management, their usage can result in adverse reactions, including gastrointestinal issues, as these drugs can also affect the prostaglandins that maintain the protective lining of the stomach. Therefore, the effect of NSAIDs that will be achieved is pain relief, but they must be used with caution because of the risk of adverse reactions.
