Question1 of 25Which of the following correctly describes the route of urine?Kidney hilus to the bladder to the ureterPelvis of the kidney to ureter to bladder to urethraGlomerulus to ureter to renal tubuleHilus to urethra to bladderKidney to bladder to ureterQuestion2 of 25What is the outermost region of the kidney called?Renal cortexRenal medullaRenal hilumRenal pelvisRenal pyramidsQuestion3 of 25Which of the following correctly describes the location of the kidneys?They are paired organs located posterior to the intestines, between the T12 and L3 vertebra, with a rich blood supply and fat capsule surrounding them.The kidney is a single organ located posterior to the intestines, between the T12 and L3 vertebra, with a rich blood supply and fat capsule surrounding them.They are paired organs located superior to the intestines, with a rich blood supply and fat capsule surrounding them.They are paired organs located posterior to the intestines, between the T12 and L3 vertebra, with a rich blood supply and no fat capsule surrounding them.They are paired organs located posterior to the intestines, between the T12 and L3 vertebra, with little blood supply.Question4 of 25Which of the following best describes the glomerulus?Series of renal tubulesSeries of arteriolesSeries of capillariesSeries of collecting ductsSeries of both arterioles and renal tubulesQuestion5 of 25An obstruction in the glomerulus would affect the flow of blood into which of the following?Renal arteryEfferent arterioleAfferent arterioleInterlobular arteryMesenteric arteryQuestion6 of 25Urine formed in the nephrons empties directly into what structure?Peritubular capillariesLoop of HenleCollecting ductUrethraRenal pelvisQuestion7 of 25Which of the following is the site where most tubular reabsorption occurs?Glomerular capsuleLoop of HenleProximal convoluted tubuleDistal convoluted tubulePeritubular capillariesQuestion8 of 25What is the process of glomerular filtration?An active transport of the fluid part of blood in the glomerular capsuleAn active transport of the blood in the peritubular capillariesA passive filtration of blood in the peritubular capillariesA passive filtration of the fluid part of blood in the distal convoluted tubuleA passive filtration of blood in the glomerular capsuleQuestion9 of 25What is the normal composition of glomerular filtrate?All components of blood except the formed elementsAll components of blood except formed elements and large proteinsOnly water and urea from the bloodOnly urea and glucose from the bloodAll components of blood except cells, large proteins, and waterQuestion10 of 25What is the specific gravity or density of normal urine?1.001 – 1.0351.030 – 1.0401.000 – 1.015less the 1.000greater than 1.035Question11 of 25The normal yellow color of urine is due to what substance?Breakdown products of WBC destructionErythropoietinDestruction of hemoglobinExcretion of ureaBreakdown of melaninQuestion12 of 25Which of the following describes urine?Water and protein not needed by the bodyWater, protein, and cells not needed by the bodyNitrogenous wastes and protein onlyNitrogenous wastes, water, and unneeded substancesWater and nitrogenous wastes onlyQuestion13 of 25Which of the following statements describes the ureters?One of the layers of the wall is smooth muscle that propels urine to the bladder.They carry the urine from the bladder to the exterior of the body.They enter the bladder on the superior surface.They are covered with capillaries that reabsorb more water from the urine.They are composed of only three layers of epithelium.Question14 of 25Which of the following describes the wall of the bladder as it fills?The stratified squamous cells become thinner.The muscular wall collapses and the transitional epithelium thins.The muscular wall stretches and the transitional epithelium thins.The bladder collapses to 5?7.5 cm.The trigone area disappears.Question15 of 25Select the item below which shows the correct order of events during micturition.Urine collects and activates stretch receptors in the bladder walls.Urine is forced past the internal sphincter.The nervous system starts smooth muscle contractions in the bladder wall.The external sphincter is voluntarily controlled by the person.1-2-3-42-3-4-13-4-2-11-3-2-41-3-4-2Question16 of 25Where is most of the water in the body located?PlasmaCellsBetween body cellsBladderCerebrospinal fluid and glandsQuestion17 of 25What is the main mechanism prompting water intake?Osmoreceptors in the kidney activate the release of ADH.Osmoreceptors in the hypothalamus activate the thirst center.Release of ADH increases the blood pressure.Release of aldosterone activates the thirst center.Excessive saliva production activates the thirst center.Question18 of 25Which body system makes corrections to low blood pH the fastest?Urinary systemEndocrine systemLymphatic systemRespiratory systemIntegumentary systemQuestion19 of 25What is the result of ADH release?Prevents excess water loss by the kidneys, increasing the blood volume and increasing blood pressurePrevents excess water loss by the kidneys, decreasing the blood volume and decreasing blood pressurePrevents excess water loss by the kidneys, decreasing the blood volume and increasing blood pressureIncreases water loss by the kidneys, increasing the blood volume and increasing blood pressureIncreases water loss by the kidneys, decreasing the blood volume and increasing blood pressureQuestion20 of 25Sodium ion concentration of the extracellular fluid is largely regulated by what hormone?ADHErythropoietinEpinephrineReninAldosteroneQuestion21 of 25Why is the excretion of bicarbonate ions by the kidney important?It maintains adequate urinary output.It maintains acid base balance of the blood.It stimulates ADH production.It stimulates erythropoietin production.It maintains urine pH between 4.5 to 8.0 range.Question22 of 25What is a likely cause for urinary retention in an elderly male?Loss of neural control over the urinary sphincterAddison’s DiseaseEnlarge prostate glandUrethritisDiabetes type IIQuestion23 of 25What is the name of the inability to voluntarily control the external urethral sphincter?PolyuriaUrethritisAnuriaIncontinenceOliguriaQuestion24 of 25What kidney disorder involves clogging of the glomerular filter with antigen antibody complexes?NocturiaDiabetes insipidusGlomerularnephritisPolycystic diseaseKidney stonesQuestion25 of 25Cloudy urine that contains white blood cells is indicative of what disorder?Urinary tract infectionAddison’s DiseaseDiabetes InsipidusHypospadiasPolycystic disease
