The oncology nurse is caring for a 24-year-old male client with testicular cancer. Cisplatin IV has been ordered. Which lab value would the nurse notify the health care provider about before administering this medication?

  • iron 129 mcg/dL
  • ammonia level 52 mcg/dL
  • creatinine clearance 23 mL/minute
  • brain natriuretic peptides (BNP) 36 pg/mL
Number 3 is correct.
Cisplatin is contraindicated and should not be given to clients with a creatinine clearance below 30 mL/min. The iron level is within normal limits and is not a contraindication of administering cisplatin. The ammonia level is also within normal limits, which is important to monitor as cisplatin should be used cautiously with hepatic impairment. BNP is used to measure the severity of heart failure; this value is within the normal range.
