If you cannot feel the liver margin, what does that indicate about hydration?

• A. Hydration is adequate
• B. They are overhydrated
• C. Hydration is insufficient
• D. Dehydration status cannot be determined

Answer: (C)

Not being able to feel the liver margin points to reduced liver size due to low circulating volume. When someone is dehydrated, decreased blood volume lowers hepatic perfusion and can shrink the liver, making its edge difficult or impossible to palpate. In contrast, adequate hydration usually keeps the liver at its normal size, and overhydration can even enlarge it from congestion. So the best interpretation of not feeling the liver margin is that hydration is insufficient.
