Certified Ostomy Care Nurse (COCN) Practice Exam

The assertion is true because the Turnbull blowhole colostomy is designed to divert fecal material away from the diseased portion of the colon while leaving that section intact. This procedure is often utilized in cases of colorectal conditions where part of the colon is affected by disease but it's deemed that the remaining colon could still function. However, the persistent presence of the diseased colon can lead to complications, including the potential for continued toxicity due to the retention of waste and the inability to adequately handle fecal material. The choice of keeping the diseased part of the colon while creating a stoma can allow for a variety of metabolic disturbances if the colon is still able to absorb produce toxins or other harmful substances. Therefore, this highlights the importance of close monitoring and management of patients who undergo such procedures, as they may require additional interventions to manage potential complications from the retained diseased tissue. The implications of this surgical strategy are crucial in ostomy care management.
