During preoperative stoma site marking, which four positions must the OMS nurse evaluate to ensure optimal pouch security and patient visibility?
Show answer →The nurse must evaluate the patient in the supine, sitting, standing, and bending (forward) positions. The goal is to identify the rectus muscle, avoid skin folds, scars, bony prominences, and the umbilical/beltline. Ensuring the patient can see the site is critical for self-care independence. \n\nExam Strategy: NAWCO emphasizes the rectus abdominis as the primary target to prevent parastomal hernias. A common distractor is suggesting only supine marking is sufficient; however, skin folds often disappear when supine but cause pouch leakage when the patient sits.
A patient asks why their ostomy paste isn't sticking the pouch to their skin. What is the most important education point regarding the primary function of ostomy paste?
Show answer →Ostomy paste is a caulk, not an adhesive. NAWCO emphasizes that paste is used to fill irregular skin contours, dips, or creases to create a level surface for the skin barrier. It should never be used as a glue to stick the pouch to the body. Strategy Tip: Watch for distractors suggesting paste increases overall adhesion; its role is solely to prevent effluent from undermining the seal by filling gaps.
A 2-week-old neonate requires a pouch change. What is the most critical consideration regarding adhesive removal to prevent Medical Adhesive-Related Skin Injury (MARSI) in this population?
Show answer →Use silicone-based, alcohol-free adhesive removers. Neonatal skin has a significantly thinner stratum corneum and reduced cohesion between the dermis and epidermis compared to adults. Avoid aggressive peeling or the use of tackifiers. Exam strategy: NAWCO 2026 guidelines emphasize low-trauma removal and the absolute avoidance of alcohol-based products due to the high risk of systemic absorption and chemical burns in premature or term neonates.
A patient with a 10-year-old colostomy reports ribbon-like stools and increased abdominal cramping. Upon inspection, the stomal orifice appears pinpoint. What is the priority assessment to determine the level of narrowing?
Show answer →The priority is a digital examination (if within scope and not contraindicated) to differentiate between skin-level (epithelial) and fascial-level stenosis. Skin-level involves scarring at the skin-mucosa junction; fascial-level involves narrowing at the abdominal wall musculature. NAWCO emphasizes that ribbon-like stools are a hallmark of stenosis. Strategy: If the finger cannot pass the skin, it's superficial; if it passes the skin but hits a shelf, it's fascial.
A urostomy patient presents with white, gritty deposits on the stoma and peri-stomal skin. What is the target urine pH range to prevent these alkaline encrustations, and what is the primary pathophysiological cause?
Show answer →Target pH: 5.5 to 6.5. Pathophysiology: Alkaline urine (pH >7.0) causes calcium and magnesium phosphates to precipitate as crystals (encrustations). These can cause stomal bleeding and skin irritation. NAWCO Exam Tip: Encrustations are a hallmark of chronic alkalinity. Distinguish from uric acid stones which form in acidic urine.
