Explanation

This statement is incorrect because the most significant malabsorption of fluids and electrolytes occurs with an ileostomy, not a colostomy.
The small intestine (ileum) is where most nutrients and a large amount of fluid and electrolytes are absorbed. An ileostomy bypasses the entire large intestine (colon), which is the primary site for water absorption.
A colostomy, which is placed in the large intestine, allows for normal absorption in the entire small intestine. The degree of water absorption depends on how much of the colon is still functional.

Option A: This is a correct statement. An ileostomy stoma is intentionally created with a pout (protrusion) to protect the surrounding skin from the corrosive, enzyme-rich liquid output.
Option C: This is a correct statement. Eversion of the stoma above the skin level is a standard technique for both colostomies and ileostomies to help direct fecal output into the pouching system and protect the peristomal skin.
Option D: This statement is technically incorrect as standard practice involves suturing the seromuscular layer, not just the muscular layer. However, the statement about malabsorption (Option B) represents a more fundamental and clinically significant physiological error.

Visual 1: Diagram - A diagram of the gastrointestinal tract comparing the anatomical locations of an ileostomy (end of small intestine) and various colostomies (ascending, transverse, descending, sigmoid). This helps visualize how much of the absorptive surface of the colon is bypassed in each case.
Visual 2: Image - A close-up photograph comparing a healthy, pouting ileostomy stoma with a healthy, less-protruding colostomy stoma. The caption should highlight the differences in appearance and relate them to the type of output.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Physiological differences and management principles of intestinal stomas (Ileostomy vs. Colostomy) as background academic context rather than a clinical decision trigger.
Understanding the difference in malabsorption is critical for nursing care. Patients with ileostomies are at a much higher risk for dehydration, electrolyte imbalances (especially sodium and potassium), and nutritional deficiencies.
Nursing interventions for an ileostomy patient focus on monitoring for dehydration (high output, low urine output, thirst, dizziness), encouraging high fluid and electrolyte intake, and meticulous skin care around the stoma due to the corrosive output.
Nursing care for a colostomy patient is more focused on managing odor, regulating bowel movements through diet (for sigmoid colostomies), and preventing constipation.

How to Approach the Question

First, identify that the question is asking for the INCORRECT statement. This means three of the options are correct facts, and one is false.
Read each option carefully and evaluate it based on your knowledge of gastrointestinal anatomy and physiology.
Consider the primary functions of the different parts of the bowel. The small intestine (ileum) is for nutrient and fluid absorption. The large intestine (colon) is primarily for water absorption.
Compare the physiological impact of an ileostomy (bypassing the colon) versus a colostomy (bypassing only part of the colon).
Evaluate the statement about malabsorption. Does it make sense that bypassing less of the absorptive surface (colostomy) would cause maximum malabsorption? This is a logical contradiction.
Review the other options regarding stoma construction (pouting, eversion). These are standard techniques to protect the skin. The statement about suturing is a fine detail, but the malabsorption statement is a major physiological principle. The most fundamentally incorrect statement is the answer.
