Understand the Problem
The question presents a worksheet regarding rectal bleeding, requiring definitions, differentiations, causes, clinical significance, diagnostic methods, and various conditions related to rectal bleeding in both adults and children.
Answer
Rectal bleeding involves blood from the lower digestive tract, while hematochezia is red blood in stools, and melena involves black stools.
Rectal bleeding is blood passed rectally from the lower parts of the digestive tract. Hematochezia is fresh red blood in stools, while melena features black, tarry stools. Common causes of rectal bleeding in adults include hemorrhoids, anal fissures, and gastrointestinal diseases.
Answer for screen readers
Rectal bleeding is blood passed rectally from the lower parts of the digestive tract. Hematochezia is fresh red blood in stools, while melena features black, tarry stools. Common causes of rectal bleeding in adults include hemorrhoids, anal fissures, and gastrointestinal diseases.
More Information
Hematochezia and melena are both symptoms of gastrointestinal bleeding. Hematochezia indicates bleeding close to the anus, while melena indicates upper gastrointestinal tract bleeding. This distinction is important for diagnosing the location and cause of the gastrointestinal bleeding.
Tips
Misunderstanding the difference between hematochezia and melena can lead to incorrect assumptions about the source of bleeding.
