1 . Diseases that primarily affect the collecting ducts create? urine high in solutes hyponatremia hypercalcemia hypertesion hyposthenuria
2.The purpose of the MWDT is to? stimulate release of aldosterone decrease medullary hypetonicity gradually increase plasma osmolality/stimulate release of ADH confirm diagnosis of diabetes insipidus confirm diagnosis of renal failure
3.Which one of the following is not a contraindication for MWDT? Hypercalcemia Azotemia Increased ALKP Hyperalbuminemia Hypernatremia
4.Antidiuretic hormone is produced in? The pars distalis The pars intermedia the pars nervosa the hypothalmus the adrenal medulla
5 . The primary effect(s) of ADH is (are): Decrease plasma osmolality, increase urine osmolality, decrease blood pressure. Increase plasma osmolality, decrease urine osmolality, increase heart rate increase osmolality of plasma and urine, increase blood pressure Decrease plasma osmolality, increase urine osmolality, increase blood pressure. Decrease plasma and urine osmolality, increase blood pressure Increase urine osmolality, little or no effect on plasma osmolality or blood pressure
6 . The segnment of the nephron that actively reabsorbs solutes, passively reabsords water and decreases the volume of glomerular filtrate by 60-70% is: proximal convulated tubule collecting ducts ascending limb of Henle's loop distal convulated tubule descending limb of Henle's loop
7 . The segment of the nephron that decreases glomerular filtrate below 1.008 is: distal convoluted tubule proximal convoluted tubule collecting ducts thin segment of Henle's loop thick segment of Henle's loop
8 . All of the following diseases cause PU/PD by altering the action of ADH except: diabetes insipidus hypercalcemia hyperadrenocorticism pyometra diabetes mellitus
9 . The specific gravity of glomerular filtrate is approximately: 1.022 1.008-1.012 1.004 1.015 1.035
10 . Renin is secreted: by the adrenal cortex by the pars distalis by the adrenal medullar by the juxtaglomerular apparatus by the distal convulated tubule
