A 30-year-old female client is receiving antineoplastic chemotherapy. Which of the following symptoms should especially concern the nurse when caring for her?

A respiratory rate of 16 breaths/min is normal and is not a cause for alarm. A pulse rate of 80 bpm is normal and is not a cause for alarm. Complaints of muscle aches are unrelated to her receiving chemotherapy. There may be other causes related to her hospital stay or the disease process. A sore throat is an indication of a possible infection. A client receiving chemotherapy is at risk of neutropenia. An infection in the presence of neutropenia can result in a life-threatening situation.
