When evaluating a client's rectal bleeding, which findings should the nurse document?

A. Color characteristics of each stool. This is the best choice as it provides important information about the possible source and nature of the bleeding (e.g., bright red indicates lower GI bleeding, while dark tarry stools indicate upper GI bleeding). B. Number of blood clots expelled with each stool. While this could be relevant, it is less commonly noted and might be more subjective unless quantified consistently. C. Unique odor noted with gastrointestinal bleeding. The odor can sometimes indicate the presence of blood, but it is not a primary characteristic to document compared to stool color and consistency. D. Evidence of internal hemorrhoids. Internal hemorrhoids might be a source of bleeding, but this requires confirmation through a physical examination, typically by a healthcare provider.
