Question

Which client taking metformin does the nurse consider at highest risk for lactic acidosis?

1.Client who is receiving dialysis
2.Client who has hyperglycemia
3.Client who is also taking oral contraceptives
4.Client who is also taking warfarin (Coumadin)

Answer 1

The client receiving dialysis is at the highest risk for lactic acidosis while taking metformin due to impaired drug clearance.

Step-by-step explanation:

The client taking metformin who is at highest risk for lactic acidosis is the client who is receiving dialysis. Metformin is known to be associated with an increased risk of lactic acidosis, a serious metabolic condition characterized by an accumulation of lactic acid, leading to an abnormally low pH in the body. Clients with renal dysfunction, as indicated by the need for dialysis, are at a higher risk due to the decreased ability to clear metformin from their system. This can lead to an accumulation of the drug and an increased risk of lactic acidosis.
