You are caring for a patient who has been vomiting and having diarrhea for the past five days. you suspect that his electrolyte levels are
respiratory alkalosis
a mountain climber at high altitude may lose consciousness as the result of
metabolic acidosis
a person with chronic diabetes with exhibit signs of
respiratory acidosis
a person with emphysema will exhibit signs of
peripheral vasoconstriction
acidosis can cause all of the following, except
promotes sodium retention in the kidneys
aldosterone
a, b, and c
angiotensin II produces a coordinated elevation in the ecf volume by
stimulates water conservation by the kidneys
antidiuretic hormone
calcitonin
calcium reabsorption by the kidneys is promoted by the hormone
result in a temporary increase in blood volume
consuming a meal high in salt will
collecting ducts
damage to the renal medulla would interfere first with the functioning of which of the following
increased thirst
dehydration will cause
there is increased activity of the parasympathetic motor neurons that control the detrusor muscle
during the micturition reflex,
albumin
each of the following is a normal constituent of urine, except
large amounts of chloride ions are lost each day in urine
each of the following statements concerning chloride ions are true, except that
increased concentration of potassium ions in the icf
factors that increase the secretion of antidiuretic hormone include all of the following, except
24 mm Hg
find the net glomerular filtration pressure with a glomarular pressure of 69 mm Hg, a pressure in the capsular space of 15 mm Hg, and a plasma osmotic pressure is 30 mm Hg.
calcitonin
high blood calcium levels stimulate the release of
respiratory alkalosis
hyperventilation as may occur during a panic attack would cause
decreased respiration rate
in response to a rapid increase of organic acids in the body, you would expect to observe all of the following, except
there is an increased permeability of the membrane of the renal collecting ducts to water
in response to high plasma osmolarity
body retains more carbon dioxide
in response to respiratory alkalosis, the
sodium and chloride ions are actively transported out of the ascending limb
in the loop of henle
the cells of the body
intracellular fluid (icf) is found in
the basic functional units of kidney
nephrons are
bundles of tissue that lie between pyramids and extend from the renal cortex toward the renal sinus
renal columns are
expanded ends of the ureters
renal pelvis is/ are
conical structures that are located in the renal medulla
renal pyramids are
internal cavities lined by the fibrous capsule and located in the area of the hilus
renal sinuses are
associated with the reaborption of sodium from the distal tubules and collecting ducts
secretion of potassium into the urine is
distal convoluted tubule
sodium reabsorption in response to aldosterone begins in the
distal convoluted tubule
some toxins are secreted into the filtrate by the
hilum
the ---------- is the medial aspect of the kidney where the renal artery and vein enter and exit the kidney.
capsule
the ------------- is a dense layer of connective tissue that covers the renal cortex
the loop of henle
the ability to form a concentrated urine depends on the functions of
loop of henle
the active transport of sodium-chloride occurs regularly at the
increases the permeability of the collecting ducts to water
the antidiuretic hormone
calcium
the cation with a plus two charge that is kept primarily in extracellular fluid is
approximately 50 percent of waste products
the cells of the proximal convolutes tubule normally reabsorb all of the following, except
all of the above
the components of extracellular fluid include all
renal artery interlobar artery arcuate artery cortical radiate artery afferent arteriole glomerulus efferent arteriole pertitubular capillary
the following is a list of the blood vessels that carry blood to the kidney
the distal convoluted tubule
the kidneys begin to make adjustments for ph at
collecting duct
the last part of the nephron is the
sodium ions
the most common problems with electrolyte balance are caused by an imbalance between gains and losses of
prevent ph changes caused by organic and fixed acids
the primary role of the carbonic acid-bicarbonate buffer system is to
sodium
the principal cation in extracellular fluid is
potassium
the principal cation in intracellular fluid is
chloride
the principle anion is extracellular fluid is
renal corpuscle
the process of filtration occurs at the
cubodial
the proximal and distal convoluted tubules are lined by ----- epithelium
produce a concentration gradient that will allow the nephron to produce a hypotonic filtrate
the role of countercurrent multiplication in the kidney is to
transitional
the ureters and urinary bladder are lined by --------- epithelium
secretes excess glucose molecules
the urinary system does all of the following, except that it
all of the above
to survive, humans must maintain a normal volume and composition of
ureters
urine is carried to the urinary bladder by
the calyces
urine moves into the renal pelvis from
a decrease in the amount of potassium in the urine
what effect would a decrease in ph have on amount of potassium ions in the urine?
there is an increase in the volume of urine produces
when the amount of sodium ion in extracellular fluid increases,
kidneys secrete more hydrogen ions
when the ph of the extracellular fluid declines, the
osmosis moves water from the icf to the ecf
when water is lost, but electrolytes are retained,
adh
which hormone affects the osmostic concentration
anp
which hormone helps to reduce blood volume and blood pressure?
renin
which hormone is released by the kidneys in response to excessive pressure?
aldosterone
which hormone plays a role in determining the rate of sodium absorption and potassium loss?
