A nurse in a provider's office is reviewing the laboratory findings of client who has been taking gemfibrozil for 3 months. Which of the following findings should the nurse expect?

The correct answer is D: Reduced triglycerides. Gemfibrozil is a lipid-lowering medication that works by decreasing triglyceride levels. The nurse should expect a reduction in triglycerides as a therapeutic effect of the medication. Option A (Increased serum creatinine) is incorrect as gemfibrozil typically does not affect creatinine levels. Option B (Reduced serum calcium) is incorrect as gemfibrozil does not impact calcium levels. Option C (Increased Hgb) is incorrect as gemfibrozil does not directly affect hemoglobin levels. Therefore, the nurse should anticipate a decrease in triglyceride levels as the expected finding in a client taking gemfibrozil.
