Which assessment finding indicates a fluid and electrolyte imbalance induced by chemotherapy if a female client is receiving chemotherapy to treat breast cancer?

Dry oral mucous membranes and cracked lips

Chemotherapy commonly causes nausea and vomiting, which may lead to fluid and electrolyte imbalances. Signs of fluid loss include dry oral mucous membranes, cracked lips, decreased urine output (less than 40 ml/hour), abnormally low blood pressure, and a serum potassium level below 3.5 mEq/L.
