10. If a client has uncontrolled hypertension which elevates MAP (mean arterial pressure) well above 180 mm Hg while capsular pressure (CP) and colloid osmotic pressure (COP) remain unchanged, what will happen, if anything, to the direction of glomerular filtration? Explain your answer making sure to define and discuss the role of all three pressures in NFP (net filtration pressure).
Which of the following is an example of autoregulation of kidney function? a. The RAAS regulates Na1 by secreting renin when blood pressure or blood volume decreases. b. The ADH system regulates water balance by decreasing water reabsorption and increasing excretion of salt. c. Receptors in the juxtaglomerular apparatus detect a higher salt concentration in the distal convoluted tubule and trigger constriction of the afferent arteriole to reduce glomerular filtration rate. d. ANF is released by the kidney to increase renin release. e. Angiotensin II lowers blood pressure by constricting arterioles.
