The nurse is caring for a client with cardiogenic shock. Which information obtained by the nurse would best suggest the patient is developing multiple organ dysfunction syndrome (MODS)?

A. Elevated serum creatinine indicates impaired renal function, which is a sign of organ dysfunction. In cardiogenic shock, decreased cardiac output reduces perfusion to vital organs, and rising creatinine is an early indicator of kidney involvement in MODS. This finding reflects multi-organ compromise rather than isolated symptoms. B. Chest pressure reflects ongoing myocardial ischemia, which is the underlying cause of cardiogenic shock, but it does not indicate that other organs are failing. C. Wheezing may indicate pulmonary congestion or fluid overload, but it is not specific for MODS. It reflects one organ system rather than multi-organ dysfunction. D. Cool extremities and weak pulses indicate poor perfusion and peripheral vasoconstriction, common in shock. While concerning, these are signs of inadequate circulation rather than definitive evidence of multiple organ failure.
