For what treatment is Dialysis provided?

Appeared in: Uttarakhand CHO - 2021

Explanation

Dialysis is a medical procedure that artificially filters waste products and excess fluid from the blood.
This function is necessary when the kidneys can no longer perform this role, a condition known as renal failure (kidney failure).
It is the primary treatment for both acute kidney injury (AKI) and end-stage renal disease (ESRD).
The procedure helps manage complications like fluid overload, high potassium levels (hyperkalemia), and uremia (toxic waste buildup).

Option A: Cardiac failure is a condition where the heart cannot pump blood effectively. Treatment focuses on improving heart function with medications, lifestyle changes, or surgery.
Option C: Liver failure involves the loss of liver function. Treatments include managing complications, supportive care, and, in severe cases, liver transplantation.
Option D: Heart failure is a synonym for cardiac failure. The treatment is aimed at the heart, not the kidneys.

Clinical Relevance

Nursing practice connection: Knowing Indications for Dialysis helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A core nursing responsibility is protecting the patient's vascular access. The arm with an AV fistula or graft is a lifeline and must be shielded from procedures like blood pressure readings or IV insertions to prevent damage and clotting.
Nurses must closely monitor patients for common intradialytic complications, especially hypotension (a sudden drop in blood pressure), which is caused by rapid fluid removal.
Patient education is vital. Nurses teach patients about dietary and fluid restrictions, signs of access site infection, and the importance of adhering to their dialysis schedule.

How to Approach the Question

First, identify the key term in the question: 'Dialysis'.
Recall the primary physiological function that dialysis replaces. Dialysis is an artificial filtration process.
Consider which organ in the body is responsible for filtering blood to remove waste and excess fluid. This is the kidney.
Therefore, the failure of this organ—renal failure—is the condition that requires dialysis.
Evaluate the options provided. Cardiac/heart failure relates to the heart's pumping function, and liver failure relates to the liver's metabolic and detoxification functions. Only renal failure matches the purpose of dialysis.
