A nurse is assisting with caring for a client with cancer who is receiving cisplatin. Select the adverse effects that the nurse monitors for that are associated with this medication. (Select one that does not apply.)
- A. Tinnitus
- B. Ototoxicity
- C. Hyperkalemia
- D. Hypomagnesemia
Correct Answer: C
Rationale: Cisplatin is an alkylating medication. Alkylating medications are cell cycle phase-nonspecific medications that affect the synthesis of DNA by causing the cross-linking of DNA to inhibit cell reproduction. Cisplatin may cause ototoxicity, tinnitus, hypokalemia, hypocalcemia, hypomagnesemia, and nephrotoxicity. Amifostine (Ethyol) may be administered before cisplatin to reduce the potential for renal toxicity. Correct answers include: 1 (Tinnitus), 2 (Ototoxicity), 5 (Nephrotoxicity), 6 (Hypomagnesemia).
