7 - Renal Stressors (part 2)

Question 1

Acute Renal Failure

Obstruction in urinary tract, benign prostatic hypertrophy (BPH), tumors, calculi, and/or secondary damage to kidneys.

a. ) prerenal
b. ) intrarenal
c. ) postrenal

Answer 1

Postrenal

Obstruction in urinary tract, benign prostatic hypertrophy (BPH), tumors, calculi, and/or secondary damage to kidneys.

Question 2

Acute Renal Failure

Any condition that interferes with blood flow to kidneys, most commonly hypovolemia and hypotension.

a. ) prerenal
b. ) intrarenal
c. ) postrenal

Answer 2

prerenal

Any condition that interferes with blood flow to kidneys, most commonly hypovolemia and hypotension.

Question 3

Acute Renal Failure

Direct damage to the kidneys by inflammation, toxins, drugs, infection, or reduced blood supply.

a. ) prerenal
b. ) intrarenal
c. ) postrenal

Answer 3

intrarenal

Question 4

Acute Renal Failure

Sudden and severe drop in blood pressure (shock) or interruption of blood flow to the kidneys from severe injury or illness.

a. ) prerenal
b. ) intrarenal
c. ) postrenal

Answer 4

prerenal

Question 5

Acute Renal Failure

Damage to kidneys themselves (kidney disease, trauma/injury, nephrotoxins, acute tubular necrosis (ATN)).

a. ) prerenal
b. ) intrarenal
c. ) postrenal

Answer 5

intrarenal

Damage to kidneys themselves (kidney disease, trauma/injury, nephrotoxins, acute tubular necrosis (ATN)).

Question 6

Acute Renal Failure

Sudden obstruction of urine flow due to enlarged prostate, kidney stones, bladder tumor, or injury.

a. ) prerenal
b. ) intrarenal
c. ) postrenal

Answer 6

Postrenal

Question 7

Acute kidney failure causes electrolyte imbalances.

Urine Na⁺ levels → prerenal = ?

Urine Na⁺ levels → intrarenal = ?

Answer 7

Urine Na⁺ levels → prerenal = low

Urine Na⁺ levels → intrarenal = high
