The nurse is caring for a patient scheduled for an infusion drip pyelography. What patient preparation is necessary for this test?
A) Restriction of fluids
B) Fluids are not restricted
C) Serum electrolytes
D) 24-hour urine test
Ans: B
Feedback: Infusion drip pyelography requires IV infusion of a large volume of a dilute contrast
agent to opacify the renal parenchyma and fill the urinary tract. This examination method is useful when prolonged opacification of the drainage structures is desired so that tomograms (body-section radiography) can be made. Images are obtained at specified intervals after the start of the infusion. These images show the filled and distended collecting system. The patient preparation is the same as for excretory urography, except that fluids are not restricted. A 24-hour urine test and serum electrolytes are not needed in preparation for an infusion drip pyelography.
