Question 1
Which statement about convexity and seal is true?
Correct Answer:
Contributes to improved seal by pressing the barrier against skin
Explanation:
Convexity adds outward pressure so the barrier can press more firmly against the peristomal skin, helping it lay flush and seal around the stoma even when the skin is uneven or recessed. This closer contact reduces gaps where leakage can occur, improving the overall seal and reducing the chance of leaks. It’s about how the barrier conforms to skin and stoma anatomy, not about increasing moisture, weakening adhesion, or causing pain when properly fitted. If convexity is oversized or applied incorrectly, irritation or discomfort can happen, but the core idea is that convexity improves the seal by pressing the barrier against the skin.
Question 2
In the TNM staging for bladder cancer, which option describes M?
Correct Answer:
Metastasis to distant sites
Explanation:
In TNM staging, M represents metastasis, meaning the cancer has spread to distant sites beyond the bladder and regional lymph nodes. This is different from the primary tumor characteristics (such as size or how deeply the tumor invades the bladder wall) and from regional lymph node involvement, which correspond to T and N. Metastasis to distant organs or tissues—like the liver, lungs, bone, or distant lymph nodes—indicates M. Recognizing distant spread helps guide treatment decisions and prognosis.
Question 3
What defines an internal fistula?
Correct Answer:
Internal - opens between two internal organs or hollow spaces
Explanation:
An internal fistula is an abnormal tract that links two internal organs or hollow spaces within the body, with no opening to the skin or outside surface. This means the drainage or passage stays entirely inside the body, connecting lumens such as bowel to bowel, bowel to bladder, or bowel to vagina. In contrast, fistulas that open to the skin or outside the body are external fistulas, because they create a pathway from an internal site to the exterior. A fistula that drains externally or one that connects to skin only would not be considered internal.
Question 4
Which of the following is a function of the skin barrier in ostomy care?
Correct Answer:
Protect the skin
Explanation:
The main idea here is that the skin barrier exists to protect the skin around the stoma. It forms a protective layer and a seal with the ostomy pouching system, shielding peristomal skin from the caustic components in the stoma output, such as digestive enzymes and moisture. This prevents irritation and skin breakdown, helping the skin stay healthy so it can tolerate the appliance and remain leak-free. Odor control isn’t the barrier’s primary job, and it doesn’t change how much output you have or how well the system filters. The barrier’s purpose is safeguarding the skin integrity and supporting a proper seal.
Question 5
What comes from the proximal opening of a loop stoma?
Correct Answer:
Proximal: Effluent (Poop)
Explanation:
The main idea is that a loop stoma has two openings, and the proximal opening is the one that carries stool out to the pouch. The bowel segment that forms the proximal lumen remains connected to the intestinal tract and continues producing fecal material, so the output there is effluent—the stool or poop. The distal opening, by contrast, is from the bypassed distal limb and typically secretes mucus, not stool. So the proximal opening releases effluent (poop). Gas can pass as well, but the primary output from the proximal end is stool.
