Rationale: To assess the effectiveness of leflunomide (Arava), a medication used to treat rheumatoid arthritis, the nurse should inquire about joint pain. Joint pain is a common symptom of rheumatoid arthritis, and improvement in joint pain indicates the medication's effectiveness in managing the condition.

Rationale: The combination of triamterene and hydrochlorothiazide is used because triamterene is a potassium-sparing diuretic, which helps retain potassium, while hydrochlorothiazide is a potassium-losing diuretic, which promotes potassium excretion. This combination helps balance potassium levels in the body, preventing imbalances that can occur when using potassium-losing diuretics alone.

Correct Answer: B

Rationale: The priority when administering etanercept (Enbrel) to a client with rheumatoid arthritis is to monitor white blood cell counts and platelet counts. Etanercept can lead to infections and pancytopenia, making it crucial to assess for changes in these blood parameters to detect any potential complications early on.
