Fever is a significant sign that alerts the nurse to the possibility of OPSI in a post-splenectomy patient, as it may indicate an infection that the body is struggling to fight without the spleen's immune support. This is a crucial symptom to monitor and act upon promptly to prevent serious complications in these individuals.
