The dye (contrast media) used in IV

urography may be nephrotoxic; therefore,
encourage increased fluids unless contraindicated
and monitor urinary output. It is essential that
preprocedure BUN and creatinine levels are
assessed on any client undergoing a procedure
where dye might be injected. The PHCP may
institute precautionary measures to prevent AKI or
use smaller amounts of the dye.
M. Renography (kidney scan)
1. Description: An IV injection of a radioisotope for
visual imaging of renal blood flow, glomerular
filtration, tubular function, and excretion
2. Preprocedure interventions
a. Verify that an informed consent was
obtained.

b. Assess for allergies.

c. Inform the client that the test requires
no dietary or activity restrictions.
d. Instruct the client to remain motionless
during the test and that imaging may
be repeated at various intervals before
the test is complete.
3. Postprocedure interventions
a. Encourage fluid intake unless
contraindicated.
b. Assess the client for signs of an allergic
reaction.
c. The radioisotope is eliminated in 24
hours; wear gloves for excretion
precautions.
d. Follow standard precautions when
caring for incontinent clients and
double-bag client linens per agency
policy.
e. If captopril was administered during
the procedure, the client’s BP should
be checked frequently.

N. Cystoscopy and biopsy of the bladder

1. Description: The bladder mucosa is examined for
