Acute Kidney Injury Flashcards
A pts serum Cr level is 0.7. The expected BUN level should be
7-14
The most common reasons for initiating dialysis in acute kidney injury include which of the following
Uremia, Volume overload, hyperkalemia, acidosis
CRRT differs from conventional intermittent hemodialysis in that
the process removes solutes and water slowly
Acute kidney injury from postrenal etiology is caused by
obstruction of the flow of urine
The most common cause of acute kidney injury in critically ill pts is
sepsis
A nurse is caring for a pt w/ acute kidney injury who is being treated w/ hemodialysis. The pt asks if they will need dialysis for the rest of their life. Which of the following would be the best response?
Recovery is possible, but it may take several months
A pt is diagnosed with acute kidney injury and has been getting dialysis 3 days per week. The pt complains of general malaise and is tachypneic. An ABG shows that the pts pH is 7.19, w/ PCO2 of 30, and bicarb level of 13. A nurse prepares to
Admin IV sodium bicarbonate
Daily weights are being recorded for the pt w a urine output that has been less than the IV and oral intake. The weight yesterday was 97.5kg. This morning it is 99kg. A nurse understands that this corresponds to a
fluid retention of 1.5L
Noninvasive diagnostic procedures used to determine kidney fx include
MRI, KUB x-ray, and renal US
Peritoneal dialysis is different from hemodialysis in that peritoneal dialysis
uses the pts own semipermeable membrane
A pt has elevated BUN and Cr levels w/ a normal BUN/Cr ratio. These levels most likely indicate
acute kidney injury, such as acute tubular necrosis (ATN)
A pt is on I&O, as well as daily weights. A nurse notes that output is considerably less than intake over the last shift, and daily weight is 1kg more than yesterday. What would be a priority action of the nurse?
Assess the clients lungs
A nurse is caring for a pt who has sustained blunt trauma to the left flank area and is evaluating the pts urinalysis results. What finding would be most concerning for the nurse?
Red blood cells and albumin in the urine
Renin plays a role in BP regulation by
activating the renin-angiotensin-aldosterone cascade
A pt is admitted w/ complaints of general malaise and fatigue, along w/ decreased urinary output. The pts urinalysis shows coarse, muddy brown granular casts and hematuria. The nurse determines that the pt has:
intrarenal disease, probably acute tubular necrosis
