Registered Dietitian Nutritionist Risk Assessment & Management 2

Question 1

A 68-year-old patient with chronic kidney disease has a GFR of 28 mL/min. Which nutrient requires the most careful restriction to prevent hyperkalemia?

Accepted Answer

Potassium

Answer

With severely reduced GFR, the kidneys cannot adequately excrete potassium, making dietary potassium restriction critical to prevent life-threatening hyperkalemia.

Question 2

When using the Malnutrition Screening Tool (MST), which two factors are assessed?

Accepted Answer

Weight loss and appetite

Answer

The MST screens for malnutrition risk using recent unintentional weight loss and poor appetite as its two key parameters.

Question 3

A patient on warfarin asks about increasing vitamin K intake. What is the safest evidence-based recommendation?

Accepted Answer

Maintain consistent daily vitamin K intake

Answer

Consistent, moderate vitamin K intake allows anticoagulation therapy to be titrated appropriately rather than causing erratic INR fluctuations from variable intake.

Question 4

Which condition is most associated with refeeding syndrome risk when initiating nutrition support?

Accepted Answer

Prolonged starvation or severe malnutrition

Answer

Refeeding syndrome occurs when carbohydrates are reintroduced after prolonged starvation, triggering a rapid intracellular shift of phosphate, potassium, and magnesium.

Question 5

A critically ill patient develops hyperglycemia during enteral nutrition. What is the primary clinical risk associated with persistent hyperglycemia in this population?

Accepted Answer

Impaired immune function and increased infection risk

Answer

Hyperglycemia in critically ill patients significantly impairs neutrophil function and promotes bacterial growth, substantially increasing infection-related morbidity and mortality.
