When thinking about the total input for the human body, it is important to consider not only what a person eats or drinks, but also what is produced by cellular metabolism. Creatinine, a waste product produced by muscle cells, is excreted by the kidneys, and measuring serum creatinine allows us to assess renal function. Normal serum creatinine is less than 1.0 mg/dL, but can rise acutely if kidney function decreases.
A 56-year-old woman comes to the emergency department with a serum creatinine concentration of 1.5 mg/dL. Assuming that there has been no change in the amount of creatinine produced by the patientâs cells, what could explain the increase in serum creatinine?
Renal function has declined, resulting in increased creatinine excretion. incorrect
Renal function has declined, resulting in decreased creatinine excretion.
Renal function has improved, resulting in increased creatinine excretion.
Renal function has improved, resulting in decreased creatinine excretion.
