For pre-dialysis CKD, a low-protein diet of 0.6–0.8 g/kg/day helps reduce uremic toxin accumulation and slows disease progression.

Question 2

Which fatty acid is the primary precursor for prostaglandin E2 (PGE2), a pro-inflammatory eicosanoid?

Accepted Answer

Arachidonic acid (AA)

Answer

Arachidonic acid, an omega-6 fatty acid, is the direct precursor for the 2-series prostaglandins, including pro-inflammatory PGE2.

Question 3

A 58-year-old woman taking warfarin wants to increase her intake of leafy greens. What is the best clinical nutritionist guidance?

Accepted Answer

Maintain a consistent, moderate intake of vitamin K-rich foods daily

Answer

Consistency in vitamin K intake allows the prescriber to stabilize the warfarin dose; drastic fluctuations, not moderate steady intake, destabilize INR.

Question 4

Which laboratory marker best reflects long-term glycemic control over approximately 3 months?

Accepted Answer

Glycated hemoglobin (HbA1c)

Answer

HbA1c reflects average blood glucose over the 90-day lifespan of red blood cells and is the gold standard for long-term glycemic monitoring.

Accepted Answer

Functional vitamin B12 deficiency

Elevated MMA with normal serum B12 indicates functional B12 deficiency, where B12 is present in blood but not adequately utilized at the cellular level.
