A client who is sent home with an ileostomy requires dietary supplementation with?

Appeared in: SCTIMST Staff Nurse - 2015 (Set-A)

Explanation

  • An ileostomy involves diverting the small intestine to an opening in the abdomen, which bypasses the entire large intestine (colon).
  • The colon's primary physiological function is the absorption of water and electrolytes, particularly sodium.
  • Due to the colon bypass, ileostomy effluent (stool) is liquid and contains high amounts of sodium and water, leading to significant and continuous losses.
  • To prevent dehydration and hyponatremia (low blood sodium), clients with an ileostomy require a higher intake of sodium in their diet.

Why Other Options Were Wrong

  • Option A: High-fibre foods are poorly digested and can cause a food bolus obstruction (blockage) at the stoma site, especially in the early postoperative period.
  • Option C: While some potassium is lost, the loss of sodium is far more clinically significant and pronounced. Routine potassium supplementation is not indicated.
  • Option D: Vitamin B12 is absorbed in the terminal ileum. An ileostomy itself does not necessitate B12 supplementation unless the absorptive site was surgically removed.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Dietary management and supplementation for a client with an ileostomy as background academic context rather than a clinical decision trigger.
  • Patient education is a critical nursing role. Nurses must teach clients with a new ileostomy to recognize the signs and symptoms of dehydration, such as increased thirst, dark urine, dizziness, and fatigue.
  • Nurses should instruct patients to liberally salt their food and consider using oral rehydration solutions (ORS), which contain a balanced mix of salt, sugar, and water, especially during hot weather or illness.
  • Monitoring stoma output is essential. An output consistently greater than 1.5 liters per day is considered a 'high-output stoma' and requires prompt medical evaluation to manage fluid and electrolyte imbalances.
How to Approach the Question
  • First, identify the key term in the question: 'ileostomy'.
  • Recall the anatomy and physiology related to an ileostomy. This procedure bypasses the large intestine (colon).
  • Consider the primary function of the bypassed organ. The colon's main role is to absorb water and electrolytes, especially sodium.
  • Deduce the direct consequence of this bypass: The body will lose large amounts of water and sodium.
  • Evaluate the options based on this physiological consequence. The need to replace lost sodium makes 'Sodium' the most logical answer.
  • Eliminate the other options by recalling their specific roles: Fibre can cause blockages, potassium loss is secondary, and Vitamin B12 absorption is site-specific (terminal ileum) and not always affected.
Concept Tested & Keywords
  • Concept Tested: Dietary management and supplementation for a client with an ileostomy.
  • Stem keywords: ileostomy, dietary supplementation
  • Lead-in keywords: requires
  • Clinical cues: The care setting changes urgency, monitoring level, and the expected nursing action.
