A nurse is beginning chelation therapy on a child for lead poisoning. Which intervention should the nurse implement during the time the child is receiving chelation therapy?
a. Calorie counts
b. Strict intake and output
c. Telemetry monitoring
d. Contact isolation
ANS: B
Because calcium disodium edetate (EDTA) and lead are toxic to the kidneys, a nurse should keep strict records of intake and output to monitor renal functioning. Adequate hydration is essential during therapy because the chelates are excreted via the kidneys. Calorie counts, telemetry, or contact isolation would not be nursing interventions appropriate for a child undergoing chelation therapy.
