UTA 5315 Exam 5 Renal And Repro
|Actual Questions And Correct Answers
2026
Inversly - correct-answer -phosphorus and calcium are _______ related
Decreases, increases - correct-answer -Calcium __________ in renal failure, so
phosphorus ______________
Nephron - correct-answer -Functions: filtration, reabsorption, secretion
glomerular filtration - correct-answer -The first step in urine formation in which
substances in blood pass through the filtration membrane and the filtrate enters
the proximal convoluted tubule of the nephron.
Glomerular filtration rate GFR - correct-answer -amount of filtrate formed in all
the renal corpuscles of both kidneys each minute; filtration of plasma per unit of
time; directly related to the perfusion pressure in the glomerular capillaries;
filtrate enters proximal tubule @ 125ml/min
,2|Page
proximal convoluted tubule - correct-answer -first section of the renal tubule that
the blood flows through; Reabsorbs all the glucose and reabsorbs amino acids,
most of the HCO3, a, Cl, phosphate, K, H20; If serum glucose is >180 mg/dL, the
renal threshold for glucose is exceeded and results in glucosuria and damage
associated with DM; When stimulated by the parathyroid hormone, this tubule
excretes phosphate; The site of action for angiotensin II, which stimulates Na,
H20, and Bicarb reabsorption
Descending loop of Henle - correct-answer -section of nephron tubing that
extends from proximal tubule; impermeable to Na, passively reabsorbs water and
concentrates urine
Pre-renal AKI - correct-answer -Type of AKI that is Vasoconstriction of renal
arteries from
Caused by impaired blood flow to the kidney -> decreased GFR
Anything that decreases renal perfusion can cause this:
Caused by:
Hypotension from any cause
-CHF or severe pulmonary dz
-Volume depletion: vomiting, diarrhea, burns, dehydration, hemorrhage
-Hypercalcemia (which may result in afferent arteriolar vasconstriction)
, 3|Page
-Medications: cyclosporine, ACE-I, NSAIDs, osmotic diuretics
Pre-renal AKI - correct-answer -FeNa of <1%
and
BUN/Creatinine Ratio of >20 means
ATN - correct-answer -FeNa of >2%
and
Normal BUN/Creatinine ratio means
Intra-renal AKI - correct-answer -Type of AKI that is caused by an issue that impairs
renal function at the cellular level in the kidney
Caused by:
ATN
Inflammatory conditions: such as glomerulonephritis, vasculitis, drug induced
toxicity such as aminoglycosides
post renal AKI - correct-answer -Type of AKI where Obstruction increases
retrograde pressure and causes acute tubular necrosis
