A nurse is educating a client about a new prescription for celecoxib. Which of the following information should the nurse include in the teaching about the medication's mechanism of action?
Correct answer
B
Rationale
The correct answer is B: Inhibits COX-2. Celecoxib is a selective inhibitor of cyclooxygenase-2 (COX-2) enzyme, which is responsible for inflammation and pain. By inhibiting COX-2, celecoxib reduces inflammation and pain without affecting COX-1, which is important for maintaining the stomach lining. Therefore, the nurse should include this information in the teaching to explain how celecoxib works. Choices A, C, and D are incorrect because celecoxib does not inhibit histamine response, COX-1, or beta receptors. These mechanisms are not relevant to the action of celecoxib in treating inflammation and pain.
