1.The patient with renal insufficiency is aware that renal function depends upon the functional
status of nephrons and asks the nurse when she will need to start dialysis based upon loss of
nephron function. The nurse responds:
A) "When about 50% of the nephrons are no longer functioning."
B) "When about 60% of the nephrons are no longer functioning." C) "When
about 70% of the nephrons are no longer functioning." D) "When about 80% of the
nephrons are no longer functioning."
2.The nurse is aware that there are three areas of the ureters that have a propensity for obstruction.
Prompt management of renal calculi is most important when the stone is located in this area of
the ureter:
A) Ureteropelvic junction
B) Ureteral segment near the sacroiliac junction
C) Ureterovesical junction
D) Urethra

B) Bicarbonate and urea D) Creatinine and chloride
4.The physician has ordered a creatinine clearance measurement for the patient with impaired
renal function. The nurse is aware that the specimens that will require collection for the
calculation of the patient's creatinine clearance include:
A) A fasting serum potassium level and a random urine sample
, B) A 24-hour urine specimen collection and a serum creatinine level midway through the urine
collection process
C) A blood, urea, a nitrogen level, and a serum creatinine level on three consecutive
mornings
D) A sterile urine specimen and an electrolyte panel, including sodium, potassium, calcium, and
phosphorus values
5.Upon assessment of the patient's bladder the nurse percusses dullness. This finding indicates:
A) Incomplete bladder emptying C) Ureteral obstruction
B) Kidney enlargement D) Dehydration
