NURS 315 EXAM CORRECT DEFINED ANSWERS 2025 What is glomerular filtration rate (GFR) and its normal range? Which diagnostic test can be used to measure GFR? - -- Glomerular Filtration Rate: The amount of blood filtered by the glomeruli in a given time. Most reliable indicator of kidney function - Normal Range: 70-135ml/min (125 mL/min) - GFR can be lower in older adults - Diagnostic Test Used to measure GFR: 24-hour urine collection, based on creatinine levels Bicarbonate normal range and changes when kidney function is impaired - -Normal Range: 22-26 mEq/L Changes: Most patients in renal failure have metabolic acidosis and low serum HCO3 − levels.
