COCN MCQ

Question 1

Which of the following best describes a healthy stoma?

Accepted Answer

Moist and pink

Answer

A healthy stoma should appear moist, shiny, and pink or beefy red, similar to the mucous membrane inside the mouth. This indicates good blood supply and tissue viability. Any deviation, such as paleness, dryness, or a dark/blue color, could signal complications and requires further assessment.

Question 2

What is the most appropriate action if the patient reports frequent pouch leakage?

Accepted Answer

Reassess pouching system fit

Answer

Frequent pouch leakage is a common and distressing issue for ostomy patients, often indicating an improper fit of the pouching system. The most appropriate action is to reassess the stoma size, shape, and peristomal skin contour to ensure the barrier opening is correct and the system adheres securely. A well-fitting system is crucial for preventing leakage and protecting the skin.

Question 3

Which material is typically used in ostomy skin barriers?

Accepted Answer

Hydrocolloid

Answer

Hydrocolloid is the most common material used in ostomy skin barriers due to its excellent adhesive properties and ability to absorb moisture. This material protects the peristomal skin from effluent, promotes a secure seal, and can even help heal irritated skin. Its flexibility and skin-friendly nature make it ideal for long-term wear.

Question 4

What should a nurse monitor in the first 24 hours after a new stoma surgery?

Accepted Answer

Stoma color and output

Answer

In the immediate 24 hours post-surgery, it is critical to closely monitor the stoma's color and the nature of its output. A healthy stoma should be pink or red and moist, indicating good blood flow; any pallor or dusky color could signal ischemia. Monitoring output helps assess bowel function and identify potential complications like obstruction or excessive fluid loss.

Question 5

What tool is used to measure the stoma for proper appliance fitting?

Accepted Answer

Measuring guide

Answer

A specialized measuring guide, often provided by ostomy product manufacturers, is used to accurately measure the stoma's diameter and shape. This precise measurement is crucial for cutting the skin barrier opening to the correct size, ensuring a snug fit that protects the peristomal skin from effluent and prevents leakage. Regular remeasurement is necessary as stoma size can change over time.
