Flashcards in Renal Deck (12):
Constricting the glomerular efferent arteriole will decrease:
Renal blood flow
Which are the normal constituents of urine?
Na, K, urea, Ca, and H2O are normally found in urine
Neurogenic bladder is associated with all of the following except:
UTI less likely
Which of the following are manifestations of end-stage renal disease?
Acute renal failure may be associated with:
obstruction of urinary tract
Which of the following could delay the onset of end stage renal failure?
Low protein diet
Decreasing GFR is associated with increased:
Your patient has developed renal failure. Give three possible causes for developing this and the mechanism for each.
Cause 1: Burn injury
Burn injuryexcessive fluid lossdec blood volumehypovolemiadec plasma blood to kidneyinadequate blood to kidneyec functionrenal failure
Cause 2: Cardiogenic Shock

Cause 3: Nephrotoxic drugs

Your patient is in renal failure and has now become anemic. Give the mechanism for this happening in the renal failure patient.

Your patient has come to the emergency with a UTI. Give three possible causes.
Cause 1: vesicoureteral reflux
Damaged vesicoureteral valvesallow bidirectional flowbacteria moves up into urinary tractdec flushing outbacteria remainsUTI
Cause 2: Chronic analgesic use
Chronic analgesic useinterrupts bladder contractionsdec flushing outstasis of urinebacteria remainsUTI
Cause 3: Neurogenic bladder
