with vague complaints of bloating, constipation, and diffuse
pelvic pain. What should the NP suspect?
a) Endometriosis.
b) Ovarian cancer.

d) Dysmenorrhea. Correct Answers b) Ovarian cancer.
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. Correct Answers 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.
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. Correct Answers b) Urine specific gravity of
1.000.
A patient is admitted with heart failure. Over a 30-hour period
the patient develops oliguria. His serum creatinine (SrCr) is
measured at 1.4; the blood urea nitrogen (BUN) is measured at
34. What type of problem is most likely?
BUN (blood urea nitrogen): 8 to 25
Serum creatinine (SrCr): 0.6 to 1.2
a) Prerenal acute kidney injury
b) Acute tubular necrosis
c) Postrenal chronic kidney injury
d) Glomerulonephritis Correct Answers a) Prerenal acute
kidney injury
