Urinalysis and Body Fluids Review
Questions and Answers (100% Pass)
All of the following are considered normal functions of the kidney


✓ regulating body hydration, elimination of nitrogenous wastes,

regulating electrolyte balance




The approximate number of nephrons contained in each kidney is:


✓ 1,000,000




The order of blood flow through the nephron is:


✓ afferent arteriole, efferent arteriole, peritubular capillaries, vasa recta




The total renal blood flow is approximately:


✓ 1200 mL/min




The total renal plasma flow is approximately


✓ 600 mL/min




The glomerular filtrate is described as a:

✓ protein-free ultrafiltrate of plasma




Increased production of aldosterone causes:


✓ increased plasma sodium levels




The primary chemical affected by the renin-angiotensin-aldosterone system

is:


✓ sodium




The specific gravity of the glomerular ultrafiltrate is:


✓ 1.01




All of the following are reabsorbed from the glomerular filtrate by active

transport


✓ glucose, sodium and amino acids




For active transport to occur, a chemical:


✓ must combine with a carrier protein to create electrochemical energy




Water is passively reabsorbed in all parts of the nephron except the:

✓ ascending loop of Henle




Most of the sodium filtered by the glomerulus is reabsorbed in the:


✓ proximal convoluted tubule




The enzyme renin is produced by the kidney:


✓ in response to low plasma sodium levels




Concentration of the tubular filtrate by the countercurrent mechanism is

dependent on all of the following


✓ high salt concentration in the medulla, water-impermeable walls of the

ascending loop of Henle, reabsorption of sodium and chloride from the

ascending loop of Henle




The osmotic gradient of the medulla:


✓ affects sodium reabsorption in the proximal convoluted tubule




Aldosterone regulates sodium reabsorption in the:


✓ distal convoluted tubule




Decreased production of vasopressin:

✓ produces a high urine volume




Production of antidiuretic hormone is controlled by the:


✓ state of body hydration




Substances removed from the blood by tubular secretion include primarily:


✓ protein-bound substances, hydrogen, and potassium




Kidneys with impaired production of ammonia will consistently produce urine

with a:


✓ high pH




To enhance the excretion of hydrogen ions, ammonia is produced by the

cells of the:


✓ distal convoluted tubule




To maintain the buffering capacity of the blood, hydrogen ions combine with:


✓ filtered bicarbonate ions




Clearance tests used to determine the glomerular filtration rate must measure

substances that are:
