A nurse is speaking to a patient about his recent bowel movement. He says, "Sometimes my bowel movements are greenish in color. Is that normal?" The nurse replies:

The correct answer is Choice A.

Choice A rationale: A pale blue stoma indicates compromised perfusion or necrosis. This is a surgical emergency requiring immediate assessment to prevent tissue death and systemic complications.

Choice B rationale: Continuous drainage may reflect normal output depending on stoma type. It’s not immediately life-threatening and doesn’t require urgent intervention.

Choice C rationale: Fecal contamination is expected with colostomies. While hygiene is important, this does not indicate a critical issue needing priority care.

Choice D rationale: A beefy red, moist stoma is the expected healthy appearance of a functioning colostomy. No intervention is needed.

The correct answer is choice b. Ascending colon.

Choice A rationale:

The sigmoid colon is the last part of the large intestine before the rectum. By this stage, the stool is usually well-formed as most water has been absorbed.

Choice B rationale:

The ascending colon is the first part of the large intestine where the stool is least formed. This is because it is the initial stage of the large intestine where water absorption begins, so the stool is still relatively liquid.

Choice C rationale:

The descending colon is further along the digestive tract, where more water has been absorbed, making the stool more formed compared to the ascending colon.

Choice D rationale:

The transverse colon is between the ascending and descending colons. While the stool here is more formed than in the ascending colon, it is less formed than in the descending and sigmoid colons.
