A nurse is collecting data from a client who is experiencing perforation of a peptic ulcer. Which of the following manifestations should the nurse expect?

A. High hematocrit: A perforated ulcer causes bleeding, which usually leads to a drop in hematocrit. B. High hemoglobin: Also unlikely with internal bleeding; levels may fall with blood loss. C. Yellowing of the skin: Jaundice suggests liver disease, not ulcer perforation. D. Acute, sharp and severe abdominal pain: Sudden, intense pain indicates perforation, a surgical emergency due to peritonitis.
