Which symptom should be reported immediately as a fluid/electrolyte imbalance due to ulcerative colitis?

• A. Thirst and dry, sticky mucous membranes
• B. Development of tetany and muscle spasms
• C. Extreme muscle weakness and tachycardia
• D. Numbness and tingling of fingers, mouth, and toes

Answer: (C)

Extreme muscle weakness with a fast heart rate signals an urgent fluid/electrolyte imbalance. In ulcerative colitis, frequent diarrhea can cause significant loss of fluids and electrolytes, particularly potassium. When potassium drops, muscles become weak and the heart compensates by beating faster, which can quickly progress to dangerous instability if not treated promptly. This combination is a red flag that requires immediate assessment and intervention to prevent serious complications like reduced tissue perfusion or shock. Thirst and dry mucous membranes can indicate dehydration, but they don’t by themselves convey the same level of immediate risk as a rapid heart rate paired with marked weakness. Numbness and tingling point to potential electrolyte changes such as calcium or magnesium disturbances, and tetany or muscle spasms suggest hypocalcemia or related issues, but the most urgent alarm in this context is the combination of weakness and tachycardia, which directly reflects significant fluid and electrolyte loss affecting cardiovascular stability.
