laboratory values are most significant for diagnosing an acute kidney injury?
a) BUN and creatinine.
b) Hemoglobin and RBC count.

Question: A patient is admitted with heart failure. Over a 30-hour period the patient develops oliguria
and is diagnosed with AKI (acute kidney injury). Which assessment finding is expected in this patient?
Urine specific gravity: 1.002 to 1.028.
a) Poor skin turgor.
b) Urine specific gravity of 1.000.
c) Urine specific gravity of 1.028.
d) Hypovolemia.
Answer:
b) Urine specific gravity of 1.000.

Question: A nurse taking care of a patient diagnosed with heart failure and prerenal AKI (acute kidney
injury) notes that "casts" are now present on the patient's urinalysis report. Which statement best
describes the pathophysiologic rational for casts in this patient?
a) As kidney tubular cells die, they slough off into the urinary tubules then are reabsorbed into the
peritubular capillaries, causing arterial blockages called casts.
b) Elevated levels of blood urea nitrogen cause the formation of crystals within the kidney tubular cells.
These crystals are known as casts.
c) Casts are evidence of dead kidney tubular cells as a result of the low cardiac output and prolonged
ischemia from the heart failure problem.
d) Oliguria has caused fluid volume overload. With a fluid volume overload, more pressure is exerted on
Bowman's capsule, causing the formation of casts.
Answer:
c) Casts are evidence of dead kidney tubular cells as a result of the low cardiac output and prolonged
ischemia from the heart failure problem.

Question: Drugs that ___________should not be used in chronic renal failure (CKD).
a) enhance potassium secretion in the distal collecting tubule (DCT)
b) enhance potassium reabsorption in the DCT
c) decrease pruritis.
d) enhance diuresis.
Answer:
b) enhance potassium reabsorption in the DCT

Question: A patient, diagnosed with CKD (chronic kidney disease) has hyperkalemia. Identify the
pathophysiologic reason for this abnormality.
