  1. A CKD patient with diabetes has an eGFR of 28 mL/min. Which protein target is most appropriate per KDOQI guidelines?

    Answer: 0.8 g/kg/day, with at least 50% from high biological value sources

    KDOQI recommends 0.8 g/kg/day for diabetic CKD patients not on dialysis, with emphasis on high biological value proteins.

  2. Which assessment tool is specifically validated for identifying protein-energy wasting in dialysis patients?

    Answer: Subjective Global Assessment (SGA)

    The 7-point Subjective Global Assessment (SGA) is validated for and widely used in dialysis patients to identify protein-energy wasting.

  3. A patient with acute kidney injury (AKI) in the ICU requiring CRRT has elevated nitrogen losses. What protein intake is recommended?

    Answer: 1.5–2.5 g/kg/day to account for CRRT-related amino acid losses

    CRRT causes significant amino acid losses; ASPEN/SCCM guidelines recommend 1.5–2.5 g/kg/day for AKI patients on CRRT.

  4. Which of the following potassium-rich foods is often INCORRECTLY assumed to be high-potassium and unnecessarily restricted in CKD patients?

    Answer: Apples and blueberries

    Apples and blueberries are relatively low in potassium and are often unnecessarily restricted; individualized dietary counseling prevents over-restriction.

  5. Intradialytic parenteral nutrition (IDPN) is MOST appropriate for which hemodialysis patient scenario?

    Answer: A malnourished patient who cannot meet nutritional needs orally or via enteral supplementation

    IDPN is reserved for malnourished dialysis patients who have failed oral and enteral nutrition interventions.

  6. A CKD stage 5 patient on a very low protein diet (0.3–0.4 g/kg/day) must receive which supplementation to prevent essential amino acid deficiency?

    Answer: Keto acid/amino acid analogues

    Ketoanalogue supplements provide essential amino acid precursors without the nitrogen load, enabling safe use of very low protein diets in CKD.

  7. A renal dietitian notes that a hemodialysis patient's normalized protein catabolic rate (nPCR) is 0.7 g/kg/day. What does this indicate?

    Answer: Protein intake below the recommended 1.0–1.2 g/kg/day for HD patients

    An nPCR of 0.7 g/kg/day is below the recommended 1.0–1.2 g/kg/day for hemodialysis, indicating insufficient protein intake.
