The following test results were obtained over a 24-hour period: urine volume = 1.4 L; urine [inulin] = 100 mg%; urine [urea] = 220 mmol/L; urine [PAH] = 70 mg/mL; plasma [inulin] = 1 mg%; plasma [urea] = 5 mmol/L; plasma [PAH] = 0.2 mg/mL; hematocrit = 0.4. Calculate the following. a. Clearance of inulin, clearance of urea, and clearance of PAH b. ERPF c. Rate of urea filtration d. Rate of urea excretion e. Rate of urea reabsorption f. Rate of PAH filtration g. Rate of PAH excretion h. Rate of PAH secretion

Step 1
Clearance of inulin, clearance of urea, and clearance of PAH To calculate the clearance of a substance, we use the formula: Clearance = (urine concentration of substance x urine volume) / plasma concentration of substance For inulin: Clearance of inulin = Show more…

14. Use the information below to calculate glomerular filtration rate Plasma creatinine: 2.3 mg/100 ml Urine creatinine: 1.6 mg/ml Urine production: 25 ml/hr A. 14.72 ml/hr B. 1.73 ml/hr C. 14.72 L/hr D. 1.73 L/hr 15. Based on the correct answer from question #14, answer the following: If urea renal clearance is 20 ml/min, predict how the kidneys handled urea. A. There has been a net secretion of urea B. There is a net reabsorption of urea C. Urea has neither been reabsorbed nor secreted D. There is not enough information to predict renal handling
Madhur L.
The amount of the filtrate formed by the kidneys are (a) $125 \mathrm{ml} / \mathrm{min}$ (b) $7.5$ litre/hr (c) 180 litre/day (d) All of these
