A 65-kg man is participating in a research study for
which it is necessary to know the volumes of his body
fluid compartments. To measure these volumes, the
man is injected with 100 mci (millicurie) of H0 and
500 mg of mannitol. During a 2-hour equilibration
period, he excretes 10% of the H,0 and 10% of the
mannitol in his urine. Following equilibration, the
concentration of H,0 in plasma is 0.213 mCi/100 ml
and the concentration of mannitol is 3.2 mg/100 mL.
• What is his total body water, his ECF volume, and his
ICF volume? is the man's total body water appropriate
for his weight?

You need to evaluate kidney function in a 55-year-old obese man with type 2 diabetes; you ask him to collect his urine over a 24-hour period. He collects 4,320 mL of urine. The clinical laboratory returns the following results from analysis of his urine and plasma samples:
Plasma creatinine = 3.0 mg/100 mL
Urine creatinine = 40 mg/100 mL
Plasma potassium = 5.0 mmol/L

(this is not the same question as '48') 49. A. Large molecules like Glucose are not filtered into the renal tubules because Glucose is too big. B. Glucose molecules are ultimately secreted into the renal tubules; thát is why Glucose is found in the urine of a normal healthy person. C. Glucose molecules are filtered into the renal tubules but are rapidly reabsorbed; that is why very little glucose is found in the urine of a healthy person. D. Plasma Electrolytes are simply too big to be filtered into the renal tubules; that is why only a small concentration of extracellular electrolytes are is found in the urine of a healthy person.arrow_forwardThe presence of either protein or glucose in a urinalysis is abnormal, but these two molecules end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen.arrow_forward
