B. Blood pressure of 120/64 to 130/72 mm Hg
C. Dry oral mucous membranes and cracked lips
D. Urine output of 400 ml in 8 hours
Correct Answer: C. Dry oral mucous membranes and cracked lips
Option C: 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.
Options A, B, and D: These values are within the normal limits.
