A client has orders for zoledronic acid (Reclast). Which lab value finding would prompt the nurse to notify the prescriber?

  1. ferritin level of 78 ng/mL
  2. magnesium level of 2.3 mEq/dL
  3. creatinine clearance of 29 mL/min
  4. platelet count of 135,000 cells/mcL
Number 3 is correct.
Rationale: Reclast is contraindicated in clients with a creatinine clearance less than 35 mL/min. The other lab values are within normal range and do not affect administration of this medication.
