A client with glomerulonephritis has a glomerular filtration rate (GFR) of 40 mL/min, as measured by a 24-hour creatinine clearance. Which is the nurse's interpretation of this finding?
a. Excessive GFR, client at risk for dehydra-tion
b. Excessive GFR, client at risk for fluid overload
c. Reduced GFR, client at risk for dehydra-tion
d. Reduced GFR, client at risk for fluid overload
D
The GFR refers to the initial amount of urine that the kidneys filter from the blood. In the healthy adult, the normal GFR ranges between 100 and 120 mL/min, most of which is reabsorbed in the kidney tubules. A GFR of 40 mL/min is drastically reduced, with the client experiencing fluid retention and risks for hypertension and pulmonary edema as a result of excess vascular fluid.
