y is 8 months pregnant. At her doctor's visit today, her blood pressure was extremely elevated (190/110). The doctor sent her immediately to the hospital. When she was admitted, her urine was positive for large amounts of protein. What was the effect on the glomerular filtration rate of Sally's extremely elevated blood pressure? (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 Blood colloid osmotic pressure was decreased, allowing proteins to pass through the glomerulus. Capsular hydrostatic pressure increased, increasing the net glomerular filtration rate. Glomerular blood hydrostatic pressure increased, causing proteins to pass through the glomerulus. There would be no effect on the net glomerular filtration rate.

Maria is 8 months pregnant. When she goes to her doctor for her checkup, the nurse takes her blood pressure. It is unusually high: 200/100 mm Hg. The nurse also collects a urine sample and detects elevated levels of protein in her urine.What do you think has happened to her urine production? (Consider the pressures involved in determining net filtration pressure and osmotic force generated by solutes in the filtrate.) a. Urine production has stayed the same. b. Urine production has increased. c. Urine production has decreased. d. It is not possible to predict the effect on urine production.
The opening indicated by the black arrow indicates a 'fenestra' or pore within the glomerular capillary endothelium. Which of the following is the approximate size of the largest molecule allowed to pass through this opening? Choose from the following: (A) 5 - 6 nm (B) 50 - 70 nm (C) 200 - 300 nm (D) 700 - 800 nm
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. What could have caused this?a. Infection and inflammation in the kidney.b. Abnormally high concentration of plasma…

A pt was born with a rare genetic disorder in which the proximal tubules of her nephrons express half the number of aquaporins as normal. What will result? A. reduced reabsorption of water, although as much reabsorption of Na+ as is typical? b. reduced reabsorption of water, Na+ and glucose in the proximal tubules? c. Reduced reabsorption of both water and Na+ in equal proportions? D. Reduced reabsorption of all materials in the proximal tubules.
Glomerular filtration can be increased by which of the following? A. Increasing blood flow via afferent arteriole B. Decreasing blood flow via afferent arteriole C. Decreasing arterial blood pressure D. Increasing blood flow via efferent arteriole The answer is (A) Increasing blood flow via afferent arteriole. Please explain why it is not the other options (B,C,D)
Drugs that increase urine flow (diuretic drugs) are often employed in the treatment of hypertension (high blood pressure) or other disease states. Three physiological categories of such drugs are ones that (i) function as loop diuretics, (ii) inhibit the action of aldosterone, and (iii) block Na+ channels in the collecting ducts. Explain why each of these categories would be expected to increase Na+ excretion and urine flow.
Atrial Natriuretic Peptide helps to reduce overall blood pressure in a variety of ways. One way is by increasing Glomerular Filtration Rate. a. Why/how would increasing GFR cause decreased blood pressure? b. To increase GFR, would Atrial Natriuretic Peptide cause constriction or dilation of afferent arterioles at the kidneys? The efferent arterioles?
Maria is 8 months pregnant. When she goes to her doctor for her checkup, the nurse takes her blood pressure. It is unusually high: 200/100 mm Hg. The nurse also collects a urine sample and detects elevated levels of protein in her urine. 1. What can account for the protein in her urine? a. Protein is a normal component of urine and is no cause for concern. b. Excessive amounts of plasma proteins are filtered at the renal corpuscle. c. Tubular cells produce additional protein in response to the elevated blood pressure. d. The tubular cells have exocytosed protein into the tubular fluid.
Is this following statement correct? In the kidney, vasoconstriction of the afferent arteriole increases glomerular filtration rate, because hydrostatic pressure in the glomerular capillaries increases (much like putting your thumb over the end of a garden hose increases the pressure and causes the water to exit the hose with greater velocity and travel a greater distance).
