Question 1

A patient with chronic kidney disease (CKD) stage 4 who is not on dialysis should have their dietary protein intake restricted to approximately:

Accepted Answer

0.6–0.8 g/kg/day

Answer

For non-dialysis CKD patients, protein restriction of 0.6–0.8 g/kg/day helps slow progression and reduce uremic symptoms.

Question 2

Which of the following lab values is most indicative of long-term glycemic control in a patient with type 2 diabetes?

Accepted Answer

Hemoglobin A1c (HbA1c)

Answer

HbA1c reflects average blood glucose over the preceding 2–3 months and is the gold standard for monitoring long-term glycemic control.

Question 3

A patient post-Roux-en-Y gastric bypass is at highest risk for deficiency of which nutrient due to bypass of the primary absorption site?

Accepted Answer

Iron

Answer

Iron is primarily absorbed in the duodenum and proximal jejunum, which are bypassed in RYGB, placing patients at high risk for iron deficiency anemia.

Question 4

For a patient with acute pancreatitis who can tolerate oral intake, the preferred feeding approach is:

Accepted Answer

Low-fat oral diet as tolerated

Answer

Current evidence supports initiating a low-fat oral diet as tolerated in mild acute pancreatitis rather than prolonged NPO status.

Question 5

Which dietary modification is the primary MNT recommendation for a patient newly diagnosed with nephrotic syndrome?
