1. In CKD nutrition assessment, 'protein-energy wasting' (PEW) is defined by the ISRNM as requiring criteria from how many of the four diagnostic categories? → At least three of the four categories
2. A cohort study follows 500 CKD patients for 5 years and measures dietary protein intake at baseline only. A key methodological limitation of this approach is: → Recall bias from a single baseline measurement may not reflect long-term intake
3. How does advanced professional practice contribute to professional excellence in CSR certification? → It enhances competency, improves outcomes, and supports continuous professional growth
4. What is the recommended daily protein intake for a stable adult hemodialysis patient per KDOQI guidelines? → 1.2–1.4 g/kg/day
5. A patient with polycystic kidney disease (PKD) asks about dietary strategies to slow cyst growth. Which intervention has emerging evidence? → Caloric restriction and time-restricted eating to reduce mTOR activation
6. The Malnutrition-Inflammation Score (MIS) validated for dialysis patients incorporates which set of parameters? → BMI, albumin, TIBC, weight changes, and physical exam findings
7. What is the relationship between advanced professional practice and overall Board Certified Specialist in Renal Nutrition professional competency? → It is an essential component that strengthens the overall competency framework
8. In assessing fracture risk for a patient with CKD-MBD, which combination of lab findings indicates the highest bone disease severity? → Elevated PTH, hyperphosphatemia, low 1,25-dihydroxyvitamin D
9. A CKD patient taking calcium carbonate as a phosphate binder is found to have hypercalcemia. What dietary counseling change is most appropriate? → Limit calcium-rich foods and discuss non-calcium binder alternatives with the care team
10. Which lab value is most useful in assessing renal function? → Serum creatinine
11. A scatter diagram comparing weekly dietary phosphorus intake (x-axis) to serum phosphorus levels (y-axis) shows a strong positive correlation. This means: → As dietary phosphorus increases, serum phosphorus tends to increase as well
12. Why is documentation important in CSR risk management? → It creates an audit trail and demonstrates due diligence
13. During a facility QAPI meeting, the team uses 'affinity grouping' after a brainstorming session. This technique is BEST described as: → Organizing ideas into natural groupings based on their relationships
14. Which electrolyte should be carefully monitored and often limited in renal nutrition therapy? → Potassium.
15. A renal dietitian notices that 40% of HD patients have serum potassium above 6.0 mEq/L. The FIRST step in a quality improvement approach is to: → Collect and analyze data to identify root causes
16. In a pragmatic RCT on MNT delivery for CKD patients, external validity refers to: → The degree to which study results can be generalized to real-world clinical practice
17. A peritoneal dialysis patient gains 4 kg over 2 months without a dietary change. Which risk should the dietitian prioritize investigating? → Glucose absorption from peritoneal dialysate
18. What distinguishes risk mitigation from risk avoidance in Board Certified Specialist in Renal Nutrition practice? → Mitigation reduces impact or likelihood while avoidance eliminates the activity entirely
19. Which document would a renal dietitian consult to find standardized performance benchmarks for phosphorus management in dialysis patients? → KDOQI Clinical Practice Guidelines
20. How is fluid management personalized in medical nutrition therapy for renal patients? → Personalized based on clinical assessment.
21. Which continuing education activity is most directly aligned with maintaining CSR competency in evidence-based practice? → Critically reviewing randomized controlled trials on protein intake in CKD patients
22. Which form of vitamin D requires activation by the kidney and is therefore deficient in patients with advanced CKD? → 1,25-dihydroxyvitamin D (calcitriol)
23. What ethical principle emphasizes respecting patient autonomy in clinical practice? → Autonomy.
24. A renal patient on hemodialysis reports feeling overwhelmed by the number of dietary restrictions. The MOST appropriate counseling strategy is to: → Prioritize the one or two most critical restrictions and address others over time
25. Iron deficiency in CKD patients receiving ESA therapy is typically defined by transferrin saturation (TSAT) below what level? → 20%
26. What is the value of active listening in CSR professional practice? → It ensures accurate understanding and demonstrates respect for the speaker
27. Why is protein intake adjusted in renal patients? → To balance nutrition and reduce kidney stress.
28. A hemodialysis patient is consistently hyperkalemic. Which cooking method is most effective for reducing potassium content in vegetables? → Leaching by peeling, soaking in water, and boiling in fresh water
29. What role does data analytics play in Board Certified Specialist in Renal Nutrition decision-making? → It supports evidence-based decisions by identifying patterns and trends in data
30. A CKD patient is prescribed an ACE inhibitor and a potassium-sparing diuretic simultaneously. Which electrolyte risk requires urgent dietary counseling? → Life-threatening hyperkalemia from additive potassium retention
