Question
Chapter 19, Problem 26RQ
Summary Introduction
To determine: The volume of blood that flows through person D’s kidneys each minute.
Introduction: The major functions of the kidney are to control the extracellular volume of blood and blood pressure, to control osmolarity, and to maintain ion balance. It also functions to control pH homeostatically, waste excretion, and hormone production.

5) Arman weighs 130 kg. Assume his total blood volume is 12%, his heart pumps his total blood volume within 90 seconds, and his renal blood flow is 20% of his cardiac output. Calculate the volume of blood that flows through Arman's kidneys each minute.
Steven is a 35 year old male. To gain a better understanding of fluid requirement, you have decided to calculate his hourly sweat rate. You have collected the following data: · Exercise duration: 2 hours· Pre-exercise body mass: 85kg· Post-exercise body mass: 82.5kg· Fluid consumed during exercise: 350mL· Urine loss during exercise: 50mL From this data, what is his hourly sweat rate? Based on this, how much fluid should he consume during training?
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
Urine potassium = 20 mmol/L
What is the net renal tubular secretion rate of potassium in the patient described in question?
Group of answer choices
.280 mmol/min
.140 mmol/min
.060 mmol/min
.030 mmol/min

- Prepared or fast foods contain high levels of sodium. An excess of sodium in the diet can increase blood pressure and increase your risk of heart attack. The average student consumes many prepared foods, resulting in an excess of sodium in the diet.Excess sodium affects aldosterone secretion and sodium ion absorption in the kidneys, respectively, in the following way: Select one: a. Aldosterone Secretion Sodium Ion Reabsorption Decreases Decreases b. Aldosterone Secretion Sodium Ion Reabsorption Decreases Increases c.

- Urine creatinine: 190 mg/dL .Plasma creatinine: 2.5 mg/dL. 24-hour urine collection: 975 mL. C(ml/min)= (U(mg/dL)x V(mL/min) )/(P(mg/dL))arrow_forwardThe steroid nandrolone, which is found naturally in horses, is administered to racing horses to aid in recovery. Because it is an anabolic steroid, nandrolone levels in excess of normal background levels disqualify a horse from racing. For example, to race in the Kentucky Derby, a gelding (a castrated male horse) may have no more than 1 ng/mL in the urine, whereas an unaltered male horse may have no more than 45 ng/mL of the metabolite estrane-3,17-diol in the urine. Knowing that nandrolone is an anabolic steroid, which hormone would you expect it to closely resemble? (testosterone cortisol O progesterone O epinephrine antidiuretic hormone During metabolism, carbon 3 and carbon 4 of nandrolone are reduced, forming the metabolite estrane-3,17-diol.
