Free CCHT Nutrition and Fluid Management Questions and Answers

Question 1

A patient on hemodialysis is prescribed a phosphate binder. When is the most effective time for the patient to take this medication?

Accepted Answer

With meals

Answer

Phosphate binders work by binding to phosphorus in food while it is in the gastrointestinal tract, preventing its absorption into the bloodstream. Taking them with meals ensures they are present when the dietary phosphorus is ingested, maximizing their effectiveness.

Question 2

Which of the following foods is highest in potassium and should be limited by most hemodialysis patients?

Accepted Answer

Potatoes

Answer

Potatoes, especially when cooked with the skin, are very high in potassium. Hemodialysis patients often have difficulty excreting potassium, which can lead to dangerous hyperkalemia, so high-potassium foods are typically restricted.

Question 3

What is generally considered a safe interdialytic weight gain (IDWG) for a hemodialysis patient?

Accepted Answer

Less than 5% of dry weight

Answer

A safe IDWG is typically considered to be less than 5% of the patient's estimated dry weight (EDW). Gaining more than this amount between treatments can lead to complications like hypertension, pulmonary edema, and increased cardiovascular strain.

Question 4

The primary reason for restricting sodium intake for patients on hemodialysis is to:

Accepted Answer

Control thirst and fluid intake.

Answer

Sodium intake is a primary driver of thirst. By restricting sodium, patients can better manage their thirst, which in turn helps control their fluid intake and limit interdialytic weight gain, reducing the risk of fluid overload.

Question 5

Compared to the general population, the protein needs of a patient on maintenance hemodialysis are typically:

Accepted Answer

Higher.

Answer

Patients on hemodialysis have higher protein requirements because some amino acids and proteins are lost during the dialysis process. A high-protein diet is essential to maintain muscle mass and overall nutritional status.
