During patient teaching, the nurse informs the patient that in preparation for an ultrasound of the lower urinary tract the patient will require:
A) Increased fluid intake to produce a full bladder
B) Intravenous administration of radiopaque contrast agent
C) Sedation and intubation
D) Injection of a radioisotope
Ans: A
Feedback: Ultrasonography requires a full bladder; therefore, fluid intake should be encouraged before the procedures. The administration of a radiopaque contrast agent is required to perform intravenous urography studies such as an intravenous pyelogram. Ultrasonography is a quick and painless diagnosis test and does not require sedation or intubation. The injection of a radioisotope is required for a nuclear scan, and ultrasonography is not in this category of diagnostic studies.
