  1. A renal dietitian is asked to lead a nutrition support team (NST) meeting regarding enteral nutrition for a critically ill AKI patient on continuous renal replacement therapy (CRRT). The protein recommendation per ASPEN/SCCM guidelines is approximately:

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

    CRRT causes significant amino acid losses, necessitating higher protein provision of 1.5–2.5 g/kg/day per critical care nutrition guidelines.

  2. A renal dietitian is auditing the facility's nutrition screening process for compliance with CMS Conditions for Coverage. The MINIMUM required frequency for nutrition reassessment of stable maintenance dialysis patients is:

    Answer: Monthly, with comprehensive assessment at least quarterly

    CMS Conditions for Coverage require monthly monitoring of nutritional status with a comprehensive assessment at least every three months for stable dialysis patients.

  3. Which serum biomarker is considered the BEST validated indicator of chronic inflammation rather than nutritional status in dialysis patients?

    Answer: C-reactive protein (CRP)

    CRP is a direct acute-phase reactant that reliably reflects inflammatory status, whereas albumin and prealbumin are negative acute-phase reactants also affected by inflammation.

  4. A renal dietitian is reviewing a patient's phosphorus intake and notes the patient consumes large amounts of cola beverages. The primary phosphorus concern with colas is:

    Answer: Phosphoric acid in colas provides highly bioavailable inorganic phosphorus with nearly 100% absorption

    Phosphoric acid in dark cola beverages contains inorganic phosphorus that is almost completely absorbed, unlike the organic phosphorus in natural foods.

  5. When a renal dietitian identifies a potential drug-nutrient interaction between mycophenolate mofetil and dietary iron in a transplant patient, the BEST clinical action is to:

    Answer: Recommend separating iron supplement or iron-rich foods from mycophenolate administration by at least two hours

    Dietary and supplemental iron can chelate mycophenolate and reduce its absorption; separating administration timing minimizes this interaction.

  6. A renal dietitian is evaluating energy needs for a non-diabetic peritoneal dialysis patient. When calculating total energy intake, the dietitian MUST account for:

    Answer: Glucose calories absorbed from peritoneal dialysate, which can contribute 300–800 kcal/day

    PD patients absorb significant glucose from dialysate (typically 300–800 kcal/day depending on dextrose concentration and dwell time), which must be factored into total energy assessment.

  7. A renal dietitian wants to evaluate the strength of evidence supporting a low-protein diet (0.6 g/kg/day) in slowing CKD progression. According to evidence grading systems, which study design provides the HIGHEST level of evidence?

    Answer: Systematic review or meta-analysis of multiple randomized controlled trials

    Systematic reviews and meta-analyses of randomized controlled trials sit at the top of the evidence hierarchy, providing the most robust and unbiased evidence synthesis.
