The nurse who is working in the emergency department is obtaining evidence for a rape kit from a woman who reports that she was raped while returning to her dormitory from the university library. Which intervention is most important for the nurse to implement?

A. Listen attentively to the client's description of the event. While important for providing emotional support, it is secondary to preserving forensic evidence. B. Report the incident to the university's security department. This is necessary but not as immediately critical as preserving evidence. C. Do not allow client to shower until all evidence is obtained. Preserving evidence is the highest priority in this situation to ensure a thorough forensic investigation and legal process. D. Determine the client's personal reaction to the reported rape. Understanding the client's emotional state is important for providing support, but it should be done after ensuring that critical forensic evidence is collected.
