Advanced Colorectal & Stoma Nursing

Healthy Stoma — Key Indicators

Normal stoma: Red/pink colour, moist mucosa, 0.5–2 cm protrusion above skin, no bleeding, peristomal skin intact.

SACS Assessment Framework

Letter	Assesses	Normal Finding
S Size	Width & length of stoma	Round/oval, consistent
A Appearance	Surface texture, oedema	Smooth, slightly moist
C Colour	Mucosal perfusion	Red/beefy red
S Skin	Peristomal condition	Intact, no erythema

Colour Assessment — Clinical Significance

Colour	Meaning	Action
Red/Pink	Normal perfusion	Routine care
Pale/White	Anaemia/vasoconstriction	Monitor, assess Hb
Dark Red/Purple	Venous congestion	Urgent review
Black/Grey	Necrosis — ischaemia	EMERGENCY surgical review

Colostomy Types

End Colostomy — Hartmann's Procedure

Sigmoid/descending colon brought out as single-lumen stoma. Rectal stump oversewn and left in situ.

Formed stool Left iliac fossa Potentially reversible

Output: semi-formed to formed stool
Change: every 3–5 days (closed bag)
Indications: obstructing Ca, diverticular perforation

Loop Colostomy

Loop of colon exteriorised over rod/bridge. Two lumen openings — proximal (functioning) and distal (mucous fistula).

Defunctioning Transverse colon Usually temporary

Rod removed at 5–7 days post-op
Semiformed output from proximal limb
Distal limb: mucous discharge only

End Ileostomy (Brooke)

Terminal ileum spout 2–3 cm above skin. High-risk for dehydration and electrolyte imbalance.

Liquid output Right iliac fossa 800–1200 ml/day normal

Risk: dehydration, hyponatraemia, hypomagnesaemia
Change: every 1–3 days (drainable bag)
Empty when 1/3 full

Loop Ileostomy

Common post-anterior resection to protect anastomosis. Also used for UC/Crohn's defunctioning.

Liquid output Temporary (8–12 weeks)

Two limbs: proximal efferent, distal afferent
Closure requires water-soluble contrast study
Same high-output risks as end ileostomy

Urostomy & Other Stoma Types

Urostomy / Ileal Conduit

10–15 cm ileal segment used to divert urine after cystectomy. Ureters anastomosed to ileal segment.

Urine output Right lower quadrant

Output: clear urine with mucous strands (normal)
Urostomy bag with non-return valve
Night bag drainage recommended
UTI risk: monitor for cloudy/offensive urine, fever

Caecostomy

Rarely performed. Tube inserted into caecum (tube caecostomy) or surgically created stoma.

Liquid output Right lower quadrant

Used for acute colonic pseudo-obstruction (Ogilvie's)
May be used for antegrade colonic enemas (ACE procedure)

Output Characteristics by Stoma Type

Stoma Type	Expected Output	Volume/Day	Electrolyte Risk	Bag Type
Sigmoid colostomy	Formed/semi-formed	150–400 ml	Low	Closed/drainable
Transverse colostomy	Soft/porridge	400–800 ml	Low-moderate	Drainable
End ileostomy	Liquid/porridge	800–1200 ml	HIGH — Na, K, Mg	Drainable
Loop ileostomy	Liquid	800–1500 ml	HIGH	Drainable
Urostomy	Clear urine + mucous	1000–2000 ml	Low (renal)	Urostomy bag

One-Piece vs Two-Piece Appliance Systems

One-Piece System

Flange and bag are combined. Simpler to use, fewer parts. The entire appliance is replaced at each change.

Best for: new ostomates, dexterity limitations, irregular stoma shape
Change frequency: every 1–3 days for ileostomy, 3–5 for colostomy
Types: closed bag (colostomy), drainable bag (ileostomy), urostomy

Two-Piece System

Separate baseplate (flange) adheres to skin; bag clicks/rolls onto flange. Bag can be changed without removing flange.

Best for: skin problems, frequent bag changes, swimming
Baseplate stays 3–5 days; bag changed 1–3 x daily
Reduces peristomal skin trauma
Coupling: adhesive coupling or mechanical click ring

Flange Sizing & Convex vs Flat Appliances

Flange sizing rule: Measure stoma with measuring guide, then cut flange opening to stoma diameter + 2–3 mm. Do NOT leave >3 mm gap (skin exposure = chemical dermatitis).

Flat Appliance

Standard for well-protruding stoma on flat/slightly convex abdominal surface. First-line choice for most ostomates.

Convex Appliance

Curved baseplate pushes peristomal skin inward, encouraging stoma protrusion. Indicated for: retracted stoma, flush stoma, stoma sited in skin fold or crease. Use support belt to enhance seal.

Stoma Measurement — Post-Op Schedule

Time Post-Op	Stoma Status	Action
Days 1–5	Oedematous, large	Measure daily, pre-cut flange
Weeks 1–6	Shrinking progressively	Remeasure at each change
6–8 weeks	Mature, stable size	Customise/pre-order cut flanges

Stoma Accessories

Barrier Rings / Seals

Mouldable hydrocolloid rings placed around stoma base. Fill uneven skin contours, prevent undercutting of effluent. Also called Eakin seals.

Stoma Paste

Alcohol-based or alcohol-free paste used to fill creases/folds around stoma. Supports adhesion and skin protection. Allow to dry 30–60 sec before applying appliance.

Stoma Powder

Absorbs moisture from wet/weeping peristomal skin. Brush off excess before applying appliance. Useful in conjunction with barrier spray (crusting technique).

Adhesive Remover

Spray or wipe to dissolve adhesive bond painlessly. Reduces mechanical trauma on removal. Essential for sensitive skin and elderly patients.

Convex Inserts

Added to flat baseplate to increase convexity. Soft vs firm convex options available. Degree of convexity: soft, medium, deep.

Hernia Support Belts

Elastic belt worn around abdomen to support parastomal hernia and improve appliance seal. Available with/without aperture.

Stoma Appliance Changing — Step-by-Step Guide ▶

Clean technique is used in community settings. Sterile technique only in immunocompromised or immediately post-operative patients.

Gather all equipment: new appliance (pre-cut or cut-to-fit), adhesive remover spray/wipe, warm water, soft cloths/gauze, scissors (if cutting), disposal bag, gloves.
Position patient: sitting, standing, or lying — whichever gives best skin access. Ensure good lighting.
Don gloves. Apply adhesive remover spray/wipe to edge of existing appliance flange.
Gently peel appliance from skin starting at top, supporting skin with one hand (peeling parallel to skin — avoid lifting at 90°).
Dispose of used appliance in disposal bag. Remove gloves, wash hands, don fresh gloves.
Clean peristomal skin with warm water and soft cloth using gentle circular motion from stoma outward. Avoid soap unless rinse-free. Do NOT use alcohol wipes on peristomal skin.
Pat skin completely dry — moisture impairs adhesion and promotes skin breakdown.
Inspect stoma (SACS) and peristomal skin. Document any changes.
If indicated: apply stoma powder to any moist/weeping skin, then barrier film spray (crusting technique). Allow to dry.
If using paste/barrier rings: apply around stoma base, filling any uneven contours.
Measure stoma if <8 weeks post-op. Cut flange opening = stoma diameter + 2–3 mm.
Remove backing paper from flange. Centre aperture over stoma, press from centre outward, applying firm pressure for 30–60 seconds (warmth activates adhesive).
For drainable bag: ensure clip/closure is secure at bottom. For two-piece: attach bag to baseplate with firm click.
Document: stoma appearance, peristomal skin condition, output type/amount, appliance used, patient tolerance.

Output Consistency Guide — Bristol Stool Scale for Ileostomy

Consistency	Bristol Scale Equivalent	Clinical Significance	Intervention
Liquid (water)	Type 7	High output, laxative effect, infection	Loperamide, ORS, review diet
Loose	Type 6	Mildly elevated output	Dietary modification
Porridge/soft	Types 4–5	Normal for ileostomy	Routine management
Semi-formed	Type 3–4	Good — colostomy normal range	No change needed
Thick/formed	Type 1–2	Risk of blockage (ileostomy)	Increase fluids, mobilise, review diet

EMERGENCY: Black/grey stoma = full thickness ischaemia/necrosis. Requires immediate surgical review — do not delay.

Peristomal Skin Problem Identification Chart ▶

Condition

Appearance

Cause

Treatment

Irritant contact dermatitis

Red, moist, weeping — mirror image of flange

Effluent contact with skin (poorly fitting appliance)

Refit appliance (2–3mm gap max), barrier powder + film, convex if retracted

Allergic contact dermatitis

Erythema/vesicles matching appliance adhesive shape

Allergy to adhesive/accessories

Patch testing, change to hypoallergenic brand, topical steroid short-term

Candida (Fungal)

Satellite lesions, pustules, itchy — beyond flange edge

Moisture, antibiotics, immunosuppression

Antifungal powder (nystatin/miconazole), keep skin dry, treat predisposing factors

Folliculitis

Papules/pustules at hair follicles

Trauma from dry shaving or forceful removal

Clip hair (not shave), adhesive remover on removal, topical antiseptic

Pseudo-epitheliomatous hyperplasia

Warty, cobblestone plaques at stoma edge

Chronic urine/effluent contact (especially urostomy)

Improve appliance fit, topical steroid, surgical excision if severe

Pyoderma gangrenosum

Painful ulcers with undermined violet edges

IBD-associated, autoimmune

Systemic steroids/immunosuppressants, wound dressings, dermatology referral

Parastomal hernia skin folds

Skin creases adjacent to bulging hernia

Parastomal hernia causing contour changes

Convex appliance, hernia support belt, surgical resiting/repair if symptomatic

Stomal Complications

Complication	Features	Incidence	Management
Retraction	Stoma below skin level. Causes leakage, poor adhesion.	10–15%	Convex appliance + belt. Surgical revision if severe. Barrier ring/paste to fill contour.
Prolapse	Stoma telescopes outward. More common in loop colostomy. Can be up to 10–30 cm.	2–10%	Manual reduction (cold compress, sugar to reduce oedema, gentle pressure). Surgical revision for recurrent/incarcerated prolapse.
Stenosis	Narrowing of stoma opening. Ribbon-like stool, difficulty passing output.	5–10%	Digital dilation (by trained nurse/clinician). Dilators. Surgical refashioning if severe.
Necrosis	Black/purple discolouration. Ischaemia due to vessel compromise during surgery or tight aperture.	1–3%	EMERGENCY. Stoma tube to assess depth. If superficial — conservative. Full thickness — urgent surgical revision.
Mucocutaneous separation	Separation at stoma–skin junction. Creates raw, moist wound.	12–24%	Alginate/hydrogel dressing to fill cavity. Convex appliance. Powder + barrier film. Usually heals by secondary intention.

Parastomal Hernia

Protrusion of abdominal contents through fascial defect around stoma. Most common late complication — incidence up to 50% by 5 years for end colostomy.

Clinical Features

Visible/palpable bulge around stoma
Appliance leakage, pain, difficulty with appliance fitting
Bowel obstruction or incarceration (rare, urgent)

Management Ladder

Conservative: hernia support belt, lifestyle modifications
Appliance modification: convex, larger flange, flexible wafer
Surgical: stoma resiting (preferred over mesh repair) if conservative fails
Mesh repair: associated with high recurrence rates

Prevention: prehabilitation, prophylactic mesh at original surgery (evidence-based for end colostomy patients).

High Output Ileostomy — Overview

Definition: Output >2000 ml/day (or >1500 ml/day persistently). Requires urgent assessment and intervention.

Electrolyte Consequences

Electrolyte	Effect	Symptoms
Sodium	Hyponatraemia	Dizziness, confusion, cramps
Potassium	Hypokalaemia	Weakness, arrhythmia
Magnesium	Hypomagnesaemia	Tremor, tetany, fatigue

Pharmacological Management

Loperamide: First-line. 2–4 mg before meals and at night. Max 16 mg/day. Take 30–60 min before meals for best effect.
Codeine phosphate: 30–60 mg QDS. Adjunct when loperamide insufficient.
Omeprazole/PPI: Reduces gastric secretions entering bowel, reduces volume.
Ranitidine (if available): Alternative H2 blocker.
Oral rehydration solution: Isotonic ORS preferred over plain water.

Body Image Disturbance — Nursing Interventions

Nursing diagnosis: Disturbed body image related to presence of stoma as evidenced by patient verbalising negative feelings about body and refusing to look at stoma.

Therapeutic Interventions

Accept: Acknowledge and validate patient's feelings without judgement. Use therapeutic silence and active listening.
Inform: Provide staged, accurate information. Use teach-back method. Include partner/family with consent.
Normalise: Share that adjustment takes 6–12 months. Introduce peer support / stoma visitor programme.
Empower: Involve patient in stoma care progressively — from observing to self-caring.
Resource: Stoma support groups, national charities (Colostomy UK, IA), online communities.

Adaptation Stages (Borwell 1997)

Stage	Patient Response	Nursing Focus
Shock	Disbelief, numbness	Presence, basic information
Retreat	Withdrawal, denial	Non-judgemental support
Acknowledgement	Anger, grief	Active listening, counselling
Adaptation	Acceptance, learning	Skills teaching, independence

Sexual Health & Intimacy After Stoma

Post-AP resection erectile dysfunction: Autonomic nerve damage during pelvic dissection. Reported in 25–75% of male patients. Requires proactive nurse assessment.

Male Concerns

Erectile dysfunction (sympathetic/parasympathetic nerve injury)
Retrograde ejaculation
Refer to urology/sexual health clinic
PDE-5 inhibitors (sildenafil) may be appropriate
Penile rehabilitation programmes

Female Concerns & General Advice

Dyspareunia possible post-pelvic surgery
Vaginal dryness (radiotherapy effect)
General: empty bag before intimacy, use bag cover/stoma lingerie
Reassure that stoma does not affect sexual function directly
PLISSIT model for sexual health discussions

Return to Activities & Lifestyle

Swimming & Water Activities

Generally safe 6–8 weeks post-op
Waterproof flanges available
Ensure bag securely sealed, empty before entering water
Saltwater: rinse appliance after

Showering

Can shower with or without appliance
Avoid direct high-pressure water on stoma
Mild soap around — not on — stoma
Change appliance immediately after if removed

Work & Exercise

Return to sedentary work: 4–6 weeks
Physical/heavy lifting work: 3–6 months
Avoid heavy lifting >5 kg long-term (hernia risk)
Sports: most activities possible with planning
Stoma guard for contact sports

Dietary Advice for Ostomates

Foods Causing Problems

Problem	Causative Foods
Gas/Wind	Onions, beans, broccoli, cabbage, carbonated drinks, beer, chewing gum
Odour	Fish, eggs, garlic, onions, asparagus, high-meat diet
Blockage (ileostomy)	Mushrooms, celery, corn, nuts, dried fruit, citrus pith, coconut
Loose output	Spicy food, alcohol, leafy greens, high-fat food

Helpful Foods

Benefit	Foods
Odour control	Yoghurt, parsley, cranberry juice, buttermilk
Thicken output	Bananas, rice, white bread, boiled potatoes, marshmallows
Reduce gas	Peppermint tea, yoghurt (live cultures)
Hydration (ileostomy)	ORS, sports drinks, soups, avoid plain water excess

Ileostomy blockage signs: No output for >4–6 hours, cramping pain, nausea/vomiting, watery discharge. Manage with warm bath, gentle massage, high fluid intake, change to low-residue diet. If no resolution in 2–4 hours — seek medical review.

Stoma Reversal — Criteria & Pre-Reversal Preparation

Criteria for Reversal Eligibility

Patient is medically fit for general anaesthesia
Original indication resolved (e.g. anastomosis healed)
Adequate anal sphincter function (pre-reversal manometry recommended)
Distal limb/rectum patent — confirmed by contrast enema or flexible sigmoidoscopy
Oncology: completion of adjuvant chemotherapy if applicable
Minimum 3 months from original surgery (typically 6–12 months)

Pre-Reversal Nursing Preparation

Bowel preparation (distal washout via mucous fistula)
Pelvic floor physiotherapy assessment
Counselling on low anterior resection syndrome (LARS)
Dietary counselling for post-reversal diet progression
Continence education — risk of frequency/urgency
Stoma site management post-reversal

ERAS Protocol — Enhanced Recovery After Surgery (Colorectal)

Evidence base: ERAS protocols reduce hospital length of stay by 30–50%, complications by 20–30%. Implementation requires multidisciplinary commitment.

Pre-Operative Elements

Element	Detail
Carbohydrate loading	200–400 ml carbohydrate drink 2–3 hrs pre-surgery (not just clear fluids). Reduces insulin resistance.
Minimal fasting	Solids until 6 hrs, clear fluids until 2 hrs pre-op. Avoids dehydration and catabolism.
Bowel prep	NOT routine for colonic resection. Selective use for low rectal/sphincter-saving procedures.
Prehabilitation	Exercise, nutrition, smoking cessation 4–6 weeks pre-op.
Stoma siting	Pre-operative marking by stoma nurse (WCNS guidelines — see accordion below).
Patient education	ERAS expectations, stoma education, discharge planning.

Intra-Operative & Post-Operative

Element	Detail
Epidural analgesia	Thoracic epidural preferred — reduces opioid requirement, facilitates early mobilisation.
NG tube avoidance	Do NOT insert routinely. If used intra-op, remove before extubation.
IV fluid restriction	Goal-directed fluid therapy. Avoid fluid overload — linked to prolonged ileus.
Early mobilisation	Sit out Day 0–1. Mobilise corridor Day 1–2. 6 hours out of bed Day 2.
Early oral intake	Sips Day 0–1. Free fluids Day 1. Light diet Day 2. Normal diet when tolerated.
Drain removal	Remove pelvic drain when output <100 ml/day, not blood-stained, no clinical concern. Usually Day 2–3.
Urinary catheter	Remove Day 1–2 unless pelvic surgery/epidural (remove with epidural).

Post-Operative Ileus vs Early Return of Bowel Function

Post-Operative Ileus (POI): Prolonged absence of bowel function beyond expected recovery. Usually >3–5 days post-op.

POI Features

Absent bowel sounds (or high-pitched tinkling)
Abdominal distension, nausea, vomiting
No flatus or stool/stoma output
Intolerance of oral intake

Risk Factors for POI

Opioid analgesia, excessive IV fluids
Prolonged surgery, open vs laparoscopic approach
Hypokalaemia, hypomagnesaemia
Intra-abdominal infection

Early Bowel Function Return: Expected after ERAS-managed colorectal surgery. Stoma output by Day 2–4 is target.

Signs of Recovery

Bowel sounds: Normal gurgling — auscultate all 4 quadrants for 1 min
Flatus: First sign of recovering peristalsis — document when first passed
Stoma output: Appearance of output in bag = active peristalsis confirmed
Tolerating oral fluids without nausea/vomiting

Stoma output is the most reliable indicator of bowel function return in the post-op period — document time of first output.

Pre-Operative Stoma Siting Checklist — WCNS Criteria ▶

WCNS (Wound Care Nurse Specialist) / WCET guidelines: Stoma should be sited by a trained stoma care nurse pre-operatively whenever possible. Emergency surgery is the exception.

Three-Position Assessment

Assess patient in all three positions to identify the optimal site:

Standing: Identify rectus abdominis muscle. Mark potential site within muscle — reduces hernia risk.
Sitting: Check site is visible to patient (below belt line), not in skin fold when seated, accessible for self-care.
Lying: Confirm no skin folds, creases, scars, bony prominences encroach on the site.

Exclusion Criteria for a Site

Bony prominences (iliac crest, costal margin, umbilicus)
Skin creases/folds that deepen in sitting/bending
Previous scars (may compromise blood supply)
Belt lines, waistband areas
Areas patient cannot see (usually below umbilicus visible)
Areas of skin disease, radiation damage

Documentation

Mark site with permanent marker, cover with transparent dressing
Document in nursing notes and inform surgical team
Provide patient education booklet at same visit

Colorectal Cancer Epidemiology in the GCC

Regional Incidence Data

Country	Ranking (Males)	Notable Points
Saudi Arabia	#2 most common male Ca	Incidence ~12.5/100,000; younger age of onset (40–50s) vs Western
UAE	#1–2 most common	Increased incidence linked to dietary westernisation
Qatar	#1 most common male Ca	Highest in GCC; QNCR data shows increasing trend
Bahrain	Top 3	National cancer registry since 1960s

GCC-specific risk factors: High red/processed meat consumption, low fibre diet, obesity epidemic, physical inactivity, later stage at diagnosis.

WOC Nursing in the GCC

WCET: World Council of Enterostomal Therapists — GCC nurses eligible for regional membership

SCFHS (Saudi): Specialist nurse classification — Stoma Care Nurse within advanced practice
QCHP (Qatar): Licensing authority; specialty nursing competencies framework

Islamic Rulings on Stoma Care

Key principle: Islamic jurisprudence (fiqh) is accommodating of medical necessity. Scholars from Al-Azhar, Saudi Scholars Committee, and Qatar Fatwa Authority have addressed stoma-related rulings.

Wudu (Ablution) with Stoma

Majority scholarly opinion: stoma constitutes a daim al-hadath (continuous state of impurity)
Ruling: Patient performs wudu at each prayer time (like person with incontinence — sahib al-udhr)
Wudu is valid for the duration of that prayer time
Stoma bag contents (najasa) do not invalidate wudu if sealed
Nurse advice: encourage patient to empty/change bag before each prayer when possible

Prayer (Salah) Validity

Prayer is valid with stoma — medical necessity (darura) accepted
Patient should try to ensure bag is empty and sealed before prayer
If unable to stand: prayer in sitting or lying position is valid
Tayammum (dry ablution) if washing is harmful to peristomal skin

Nursing role: Inform patients of scholars' accommodations proactively. Refer to hospital chaplain/imam for personalised guidance. Do not assume patients know their options.

Ramadan Fasting with a Stoma

Medical ruling: Those for whom fasting would cause harm are exempt (Quran 2:185). Ostomates, especially ileostomates, should consult with their physician AND religious scholar.

Ileostomy — High Risk for Fasting

Dehydration risk significantly increased during long fasting hours (16–18 hrs in GCC summer)
Many scholars advise ileostomates not to fast unless clinically stable
Fidya (charity payment) as alternative if unable to fast/make up days

Colostomy — Generally Safer

Less electrolyte loss, formed output
Many sigmoid colostomates fast successfully
Individual medical assessment required

Dietary Modification Strategy

Suhoor (pre-dawn): High complex carbohydrate + protein meal. ORS drink. Avoid high-salt foods. Take loperamide if ileostomy.
Iftar (breaking fast): Re-hydrate gradually with ORS/isotonic drinks first. Avoid large bolus meals — increased gas/bloating. Small frequent meals preferred.
Evening hydration: 1.5–2 L fluids between iftar and suhoor.
Monitor: Daily weight, urine colour, stoma output volume. Stop fasting if symptomatic dehydration.

Cultural Considerations in Stoma Teaching

Gender & Modesty

Preferred: Same-gender nurse for stoma teaching and physical assessment — particularly important for female patients
Request from patient should be accommodated where possible
Male family member (mahram) may wish to be present for female patient education
Use clinical draping to maximise dignity during demonstrations

Arabic Patient Education Resources

Arabic-language stoma leaflets: available from Coloplast, Hollister, Salts (request from company medical liaison)
Video resources in Arabic: Saudi MOH patient education portal
King Faisal Specialist Hospital (KFSH) stoma nursing team — Arabic language material
Certified medical interpreter — must be used when language barrier exists. Family members should NOT interpret medical discussions.

GCC Exam Preparation — DHA / MOH / SCFHS / QCHP Style MCQs

1. A patient with an end ileostomy has a 24-hour output of 2,400 ml. Their serum magnesium is 0.6 mmol/L (normal 0.7–1.0). Which of the following is the MOST appropriate initial nursing intervention?

A. Administer IV normal saline 1 L over 8 hours
B. Administer loperamide 4 mg before each meal and at bedtime, and commence oral rehydration solution
C. Nil by mouth and insert nasogastric tube
D. Apply a high-output stoma bag and observe for 24 hours

Answer: B. High-output ileostomy management begins with anti-motility agents (loperamide 4 mg QID — up to 16 mg/day) and isotonic ORS. Hypomagnesaemia is a recognised complication of high-output ileostomy. Plain water should be avoided as it can worsen sodium and electrolyte depletion.

2. During a routine stoma assessment on Day 5 post-colostomy formation, the nurse observes the stoma is black in colour at the tip. The patient is haemodynamically stable. What is the priority nursing action?

A. Apply a silver-impregnated dressing to the stoma
B. Administer topical honey and review in 24 hours
C. Immediately inform the surgical team and prepare for urgent surgical assessment; insert a stoma tube to assess depth of necrosis
D. Increase the flange aperture size to reduce pressure on the stoma

Answer: C. Black discolouration indicates stoma necrosis (ischaemia). Surgical emergency. A narrow tube or glass tube can be used to assess depth — superficial may be managed conservatively, but full-thickness necrosis requires surgical revision. Do not delay notifying the surgical team.

3. According to WCNS pre-operative stoma siting guidelines, in which of the following positions should the patient be assessed to confirm the optimal stoma site?

A. Supine only
B. Standing and sitting only
C. Standing, sitting, and lying (supine)
D. Sitting and walking only

Answer: C. All three positions are required. Standing confirms visibility and rectus siting; sitting confirms no skin folds engulf the site; lying confirms the site is within the rectus abdominis and avoids bony prominences. This is a key WCNS/WCET standard.

4. A Muslim patient with a sigmoid colostomy asks the nurse about performing wudu (ablution) for prayer. The MOST accurate nursing response is:

A. "You are exempt from prayer entirely due to your stoma."
B. "Your wudu will remain valid all day as long as the bag does not leak."
C. "Most Islamic scholars classify a stoma as a continuous impurity (sahib al-udhr), meaning you perform wudu at each prayer time — it remains valid for that prayer period. I recommend consulting your hospital's imam for personalised guidance."
D. "You must perform ghusl (full bath) before each prayer."

Answer: C. The correct Islamic ruling for a stoma is analogous to sahib al-udhr (person with continuous minor impurity, like chronic incontinence). Wudu at each prayer time is valid for that prayer. The nurse should inform and refer — not decide for the patient on religious matters.

5. When sizing a stoma appliance flange aperture, the correct measurement is:

A. Exactly the same size as the stoma diameter
B. 5–8 mm larger than the stoma diameter
C. 2–3 mm larger than the stoma diameter
D. 10 mm larger to allow for post-operative oedema

Answer: C. The flange aperture should be cut to stoma diameter + 2–3 mm. Less than 2 mm risks cutting off blood supply; more than 3 mm exposes peristomal skin to effluent, causing irritant contact dermatitis. This is a fundamental stoma nursing principle assessed in all GCC licensing exams.
