The client has severe metformin-associated lactic acidosis in the setting of acute kidney injury. Metformin is stopped immediately, emergency supportive measures are instituted in the hospital, and prompt hemodialysis is recommended to correct acidosis and remove accumulated metformin. Continuing the drug, delaying notification, restricting resuscitation, or arranging outpatient care is unsafe.
In-depth explanation
Clinical reasoning
Renal impairment promotes metformin accumulation. Marked lactate elevation, acidemia, tachypnea, weakness, and gastrointestinal symptoms indicate a medical emergency rather than routine medication intolerance.
Decision rule
Suspected metformin-associated lactic acidosis requires immediate drug discontinuation, hospital supportive care, acid-base and hemodynamic monitoring, and prompt dialysis preparation.
