1. Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?
- A. Excessive doxorubicin can result in myelosuppression.
- B. Exceeding the lifetime cumulative dose limit of doxorubicin may lead to extravasation.
- C. An excess amount of doxorubicin can lead to cardiomyopathy.
- D. Exceeding the lifetime cumulative dose limit of doxorubicin may cause red-tinged urine and sweat.
