A patient has severe flank pain. The urinalysis reveals presence of calcium phosphate crystals. The nurse will anticipate an order for which diagnostic test?
a. Intravenous pyelogram
b. Mid-stream urinalysis
c. Bladder scan
d. Cystoscopy
ANS: A
Flank pain and calcium phosphate crystals are associated with renal calculi. An intravenous pyelogram allows the provider to observe pathological problems such as obstruction of the ureter. A mid-stream urinalysis is performed for a routine urinalysis or if an infection is suspected; a urinalysis was already performed, a mid-stream would not be obtained again. A cystoscopy is used to detect bladder tumors and obstruction of the bladder outlet and urethra. A bladder scan measures the amount of urine in the bladder.
