Summary Introduction
Case summary:
The GFR of a patient with a kidney disease is found to be approximately 35 mL/min. The medication taken by him gets excreted from the body, under normal conditions. However, his plasma contains a higher than normal concentration of the medication.
Characters in the case:
Mr. Wu, who is suffering from the kidney disease.
Adequate information:
The GFR of the patient (as estimated value, obtained through inulin administration) was found to be 35 mL/min, which is significantly lower than the normal value of 125 mL/min (milliliter per minute).
To determine:
The health of his kidneys. Also, the relation between the decreased GFR and the high level of medication in his plasma.

Which of the following describes why a very low GFR is not beneficial?
a. Too many substances including wastes will be reabsorbed due to the reduced flow
b. Filtered substances will pass by too quickly to be adequately reabsorbed
c. There will be insufficient secretion of substances in the peritubular capillaries
d. A low GFR is always beneficial
The kidneys assist in the regulation of blood pressure via regulation of blood volume. How is renal regulation of blood volume achieved? Categorize your answers in terms of effects on GFR and on reabsorption.
Thank you!
Fred was diagnosed 6 months ago with liver cancer. His liver is no longer able to make the necessary amount of proteins needed by the body. What effect, if any, would this have on the net glomerular filtration rate?
(Hint, decide which of the 3 forces contributing to the net filtration rate is affected. Then adjust numbers in the equation to determine if there is an increase, decrease, or no change to the net filtration rate).
Group of answer choices
A) Blood colloid osmotic pressure would be decreased, increasing the net glomerular filtration rate.
B) Blood colloid osmotic pressure would be decreased, decreasing the net glomerular filtration rate.
C) Capsular hydrostatic pressure would be decreased, increasing the net glomerular filtration rate.
D) Capsular hydrostatic pressure would be decreased, decreasing the net glomerular filtration rate.
E) There would be no effect on the net glomerular filtration rate.

- What happens to urine concentration and volume when a person is dehydrated? (Please explain what specifically occurs in the kidneys)arrow_forwardA patient arrives in the ER after suffering a fall from a third floor window. He has multiple obvious fractures, is unconscious and unresponsive, and has a blood pressure of 50/0 and pulse that is very rapid and thready. One of the many “first things” to be done for him is insertion of a foley catheter into his urinary bladder to determine if his glomerular filtration pressure is greater than 10mmHg. Why? A) If his blood pressure is adequate to give him a glomerular filtration pressure greater than 10mmHg, he will make at least 50cc/hr of urine and thus will be able to regulate his electrolytes pH, and measuring urine output, thus glomerular filtration pressure, tells the medical staff whether their resuscitation efforts are working and adequate B) None of these answers is correct C) Measuring urine output, thus glomerular filtration pressure, tells the medical staff whether their resuscitation efforts are working and adequate D) Inserting a foley catheter is actually not an…arrow_forwardWhich of the following statements about the kidney is false? a.

- Which one of the following statements is false?a. Blood pressure in the glomerular capillaries is greater than the osmotic pressure exerted by proteins in the plasma within the glomerular capillaries.b. If the osmotic pressure exerted by solutes in the peritubular capillaries is greater than the blood pressure in those capillaries, then water will be reabsorbed.c. Endothelial cells in glomerular capillaries are highly permeable, facilitating filtration of fluid into Bowman’s capsule.d. Constriction of the afferent arteriole is likely to reduce the volume of filtrate appearing in Bowman’s capsule.e. The efferent arteriole carries blood from the glomerular capillaries directly to the renal vein.0.5 pointsQuestion 2Your doctor calls with the results of your urinalysis and tells you that they found proteinuria, the presence of abnormal amounts of protein in your urine sample.

- Is this following statement correct?
