A client is receiving chemotherapy to treat breast cancer. Which assessment finding indicates a chemotherapy-induced complication?

Serum potassium level of 2.6 mEq/L

Explanation:

Chemotherapy has many side effects like nausea, vomiting, diarrhea, fatigue, fever, etc. Vomiting and diarrhea can affect the fluid and electrolyte balance adversely in the body. This can lead to a reduction in the serum potassium level.

A low level of potassium in the body can lead to weakness, cramp, paralysis, twitch, abnormal heart rhythm, etc. The normal blood potassium level is 3.6 to 5.2 millimoles per liter so a serum potassium level of 2.6 mEq/L is the finding that indicates a chemotherapy-induced complication.
