Board Certified Specialist in Renal Nutrition (CSR) Exam — Questions and Answers

Question 1: A 65-year-old diabetic hemodialysis patient has a glycated hemoglobin (HbA1c) of 5.8% but frequently reports hypoglycemic episodes post-dialysis. What explains this discrepancy and what is the dietary recommendation?

HbA1c is falsely low in dialysis patients due to hemolysis/anemia; monitor glucose directly and ensure adequate carbohydrate intake around dialysis (Correct answer)
Increase insulin dosage to bring HbA1c below 5.5%
HbA1c is accurate; the patient is fabricating hypoglycemic episodes
Restrict all carbohydrates to prevent glycemic variability

Correct answer: HbA1c is falsely low in dialysis patients due to hemolysis/anemia; monitor glucose directly and ensure adequate carbohydrate intake around dialysis

HbA1c is unreliable in dialysis patients because shortened red blood cell survival leads to falsely low values; glycemic monitoring and dietary management should be based on direct glucose readings.

Question 2: A renal dietitian reads a study reporting an odds ratio (OR) of 2.4 for hyperphosphatemia among CKD patients consuming processed foods. How should this OR be interpreted?

Processed food reduces hyperphosphatemia risk by 2.4 times
Patients eating processed foods are 2.4 times more likely to develop hyperphosphatemia (Correct answer)
The relative risk reduction is 2.4
2.4% of the study population developed hyperphosphatemia

Correct answer: Patients eating processed foods are 2.4 times more likely to develop hyperphosphatemia

An OR of 2.4 means the odds of hyperphosphatemia are 2.4 times higher in those exposed to the risk factor compared to unexposed individuals.

Question 3: A dialysis patient reports using herbal supplements including licorice root. What is the primary nutritional concern the renal dietitian should address?

Potassium and sodium content that may worsen electrolyte imbalances (Correct answer)
Fat-soluble vitamin toxicity from herbal extracts
High phosphorus content interfering with binder efficacy
Interference with iron absorption from dialysis supplements

Correct answer: Potassium and sodium content that may worsen electrolyte imbalances

Many herbal supplements contain hidden potassium, sodium, or other minerals that can worsen electrolyte imbalances in renal patients.

Question 4: A renal dietitian is developing a risk mitigation plan for a patient with CKD stage 5 and anorexia. Oral nutritional supplements (ONS) are prescribed. Which monitoring parameter best determines whether ONS is effectively reducing malnutrition risk?

Stabilization or improvement in dry weight and serum albumin over 4–8 weeks (Correct answer)
Normalized serum bicarbonate indicating metabolic balance
Reduction in BUN indicating improved protein metabolism
Serum phosphorus trending toward normal range

Correct answer: Stabilization or improvement in dry weight and serum albumin over 4–8 weeks

Stabilization or improvement in dry weight combined with rising serum albumin over 4–8 weeks is the best combined indicator that ONS is successfully reversing nutritional decline.

Question 5: A renal dietitian notes that a hemodialysis patient's normalized protein catabolic rate (nPCR) is 0.7 g/kg/day. What does this indicate?

Adequate protein intake consistent with dietary recommendations
Excessive protein intake causing uremic toxin accumulation
Protein intake below the recommended 1.0–1.2 g/kg/day for HD patients (Correct answer)
Normal catabolism with no dietary intervention needed

Correct 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.

Question 6: KDOQI recommends monitoring serum phosphorus in hemodialysis patients. What is the recommended target range for serum phosphorus according to current KDIGO CKD-MBD guidelines?

1.0–2.5 mg/dL
2.5–3.5 mg/dL
5.5–7.0 mg/dL
3.5–5.5 mg/dL (Correct answer)

Correct answer: 3.5–5.5 mg/dL

KDIGO 2017 CKD-MBD guidelines recommend maintaining serum phosphorus within or toward the normal range (2.5–4.5 mg/dL for CKD Stage 5D), as hyperphosphatemia is associated with cardiovascular calcification and mortality.

Question 7: A 58-year-old male on hemodialysis presents with serum potassium of 6.8 mEq/L after reporting he consumed a large amount of tomato sauce with pasta. Which dietary modification is the MOST urgent recommendation?

Eliminate all fruits from the diet
Limit tomato-based products and other high-potassium foods to reduce intake (Correct answer)
Increase fluid restriction to dilute potassium levels
Add a sodium bicarbonate supplement to shift potassium intracellularly

Correct answer: Limit tomato-based products and other high-potassium foods to reduce intake

Limiting high-potassium foods like tomato products is the primary dietary intervention for hyperkalemia management in dialysis patients.

Question 8: A CKD stage 3b patient reports consuming a high-protein diet (1.5 g/kg/day) for weight loss. What is the primary nutritional risk the dietitian should communicate?

Excessive calcium intake from dairy-based protein sources
Inadequate fiber intake from high protein foods
Protein-induced metabolic alkalosis
Excessive phosphorus and potassium intake accelerating CKD progression (Correct answer)

Correct answer: Excessive phosphorus and potassium intake accelerating CKD progression

High protein diets increase phosphorus and potassium load while also generating acid that accelerates hyperfiltration, all of which can hasten CKD progression.

Question 9: A patient with nephrotic syndrome and serum albumin of 2.1 g/dL is at elevated risk for which specific nutritional complication?

Fat-soluble vitamin and zinc deficiency due to urinary protein losses (Correct answer)
Hypervitaminosis A from reduced renal clearance
Water-soluble vitamin toxicity
Vitamin B12 toxicity from impaired renal excretion

Correct answer: Fat-soluble vitamin and zinc deficiency due to urinary protein losses

Nephrotic syndrome causes massive urinary losses of carrier proteins, leading to deficiencies in zinc, copper, and fat-soluble vitamins like vitamin D that are protein-bound.

Question 10: Which type of artificial intelligence application has the most potential to assist renal dietitians in identifying patients at risk for protein-energy wasting (PEW) before clinical signs appear?

Machine learning model trained on longitudinal lab, dietary, and body composition data to predict PEW onset (Correct answer)
Appointment reminder text messaging system
Electronic signature capture for informed consent
Chatbot providing static dietary handouts

Correct answer: Machine learning model trained on longitudinal lab, dietary, and body composition data to predict PEW onset

Machine learning models can detect subtle patterns across multiple data streams that precede overt PEW, enabling earlier intervention.

Question 11: Which dialysis modality results in greater continuous protein and amino acid losses due to membrane permeability?

Peritoneal dialysis (Correct answer)
Conventional hemodialysis (3×/week)
High-flux hemodialysis
Intermittent hemodiafiltration

Correct answer: Peritoneal dialysis

Peritoneal dialysis results in significant ongoing protein and amino acid losses through the peritoneal membrane with each exchange.

Question 12: 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:

Immediately restrict all patients to 1000 mg potassium diet
Report the issue to the medical director and take no further action
Collect and analyze data to identify root causes (Correct answer)
Discharge non-compliant patients from the program

Correct answer: Collect and analyze data to identify root causes

QI methodology requires root cause analysis before implementing interventions to ensure the correct problem is addressed.

Question 13: Which of the following electrolyte abnormalities is MOST commonly seen in the early post-kidney transplant period and requires dietary management?

Hyperkalemia from calcineurin inhibitor use and hypophosphatemia from urinary phosphate wasting (Correct answer)
Hyponatremia and hyperphosphatemia
Hypomagnesemia and hypernatremia exclusively
Hypokalemia and hypophosphatemia

Correct answer: Hyperkalemia from calcineurin inhibitor use and hypophosphatemia from urinary phosphate wasting

Post-transplant, calcineurin inhibitors (tacrolimus, cyclosporine) impair renal potassium excretion → hyperkalemia. High GFR post-transplant combined with post-hyperparathyroidism → phosphate wasting → hypophosphatemia. These are the most common electrolyte issues in the early post-transplant period.

Question 14: A CKD patient with diabetes has an eGFR of 28 mL/min. Which protein target is most appropriate per KDOQI guidelines?

No protein restriction; focus solely on glycemic control
0.6 g/kg/day with ketoanalogue supplementation
0.8 g/kg/day, with at least 50% from high biological value sources (Correct answer)
1.2–1.4 g/kg/day to prevent catabolism

Correct 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.

Question 15: Which risk factor most significantly increases the likelihood of developing oxalate nephropathy in patients who have had Roux-en-Y gastric bypass surgery?

Excessive vitamin C supplementation only
Hypercalciuria from calcium supplement overuse
Enteric hyperoxaluria from fat malabsorption (Correct answer)
Reduced water intake post-surgery

Correct answer: Enteric hyperoxaluria from fat malabsorption

After gastric bypass, fat malabsorption causes unabsorbed fatty acids to bind calcium in the gut, leaving oxalate free to be absorbed and excreted in high concentrations by the kidneys.

Question 16: Growth hormone resistance in children with CKD is mediated by which mechanism most directly linking uremia to impaired linear growth?

Excess dietary potassium directly suppressing growth plate activity
Vitamin C deficiency preventing collagen formation in growth plates
Excessive dietary protein intake suppressing GH receptor expression
Uremia-related downregulation of hepatic GH receptor and postreceptor signaling defects (reduced Janus kinase 2/STAT5 activation), leading to low IGF-1 production despite normal or elevated GH levels (Correct answer)

Correct answer: Uremia-related downregulation of hepatic GH receptor and postreceptor signaling defects (reduced Janus kinase 2/STAT5 activation), leading to low IGF-1 production despite normal or elevated GH levels

CKD causes uremic resistance to GH by downregulating hepatic GH receptors and impairing intracellular GH signaling (JAK2/STAT5 pathway), resulting in low IGF-1 levels despite elevated serum GH. This is the molecular basis for growth failure in pediatric CKD.

Question 17: According to professional standards, which of the following is the most appropriate way for a CSR to stay current with evolving renal nutrition evidence?

Subscribing to peer-reviewed journals such as JASN, AJKD, and JREN and critically appraising new research (Correct answer)
Relying exclusively on manufacturer-provided education from supplement companies
Attending only employer-mandated training without independent learning
Following clinical protocols from five years ago to ensure consistency

Correct answer: Subscribing to peer-reviewed journals such as JASN, AJKD, and JREN and critically appraising new research

Engaging with peer-reviewed literature and applying critical appraisal skills is the standard for evidence-based professional development in specialty practice.

Question 18: How do CSR professionals establish measurable quality objectives?

Using vague aspirational goals
Comparing only to competitors
Through subjective assessment alone
Defining specific, measurable, achievable, relevant, and time-bound targets (Correct answer)

Correct answer: Defining specific, measurable, achievable, relevant, and time-bound targets

Quality objectives in CSR practice follow SMART criteria to ensure they can be tracked, achieved, and meaningfully evaluated.

Question 19: A renal dietitian is employed by a dialysis company that instructs staff to promote a specific phosphate binder for which the company has a financial arrangement. The dietitian's ethical obligation is to:

Refuse to discuss phosphate binders with patients until the arrangement ends
Report the company to the FDA without first addressing it internally
Disclose the financial relationship to patients and recommend binders based on clinical evidence and patient preference (Correct answer)
Follow the company directive since employment obligations supersede professional ethics

Correct answer: Disclose the financial relationship to patients and recommend binders based on clinical evidence and patient preference

Professional ethics require transparency about conflicts of interest and prioritizing evidence-based, patient-centered recommendations over corporate directives.

Question 20: Which CKD complication is DIRECTLY managed through dietary bicarbonate supplementation or alkali-producing food choices?

Secondary hyperparathyroidism
Hyperphosphatemia
Metabolic acidosis (low serum bicarbonate) (Correct answer)
Hyperkalemia

Correct answer: Metabolic acidosis (low serum bicarbonate)

Metabolic acidosis (serum HCO3 < 22 mEq/L) in CKD is treated with oral bicarbonate supplements (sodium bicarbonate or sodium citrate) and/or increased intake of base-producing foods (fruits, vegetables) to replenish bicarbonate and correct the acidosis.

Question 21: When transitioning a pediatric CKD patient from dialysis to a kidney transplant, which nutritional counseling topic is MOST critical in the FIRST clinic visit post-transplant?

Food safety for the newly immunocompromised patient: avoid undercooked meats, raw eggs, unpasteurized dairy and juices, and raw sprouts — while liberalizing previous electrolyte restrictions (Correct answer)
Maintaining the same strict potassium and phosphorus restrictions from dialysis
Continuing fluid restriction at dialysis levels
Starting a very-high-protein (3 g/kg/day) diet immediately post-transplant

Correct answer: Food safety for the newly immunocompromised patient: avoid undercooked meats, raw eggs, unpasteurized dairy and juices, and raw sprouts — while liberalizing previous electrolyte restrictions

Post-transplant immunosuppression makes foodborne pathogens life-threatening. The FIRST priority is food safety education — the transition FROM dialysis restrictions AND the new risks of immunosuppression. Previous electrolyte restrictions (often strict on dialysis) are typically liberalized as the new kidney improves excretory function.

Question 22: Which serum marker, when persistently low, is the strongest independent predictor of mortality risk in dialysis patients according to current evidence?

Transferrin
C-reactive protein (CRP)
Serum albumin (Correct answer)
Pre-albumin (transthyretin)

Correct answer: Serum albumin

Serum albumin below 3.5 g/dL is consistently associated with significantly increased all-cause and cardiovascular mortality in dialysis patients, despite its role as an inflammation marker.

Question 23: A renal dietitian wants to use asynchronous store-and-forward telehealth to review a patient's 3-day food diary. Which advantage does this approach offer compared to a synchronous video visit?

It provides real-time feedback during the food logging process
It requires the patient to have a high-speed internet connection
It replaces the need for lab monitoring
It allows the dietitian to review detailed records at a convenient time without requiring the patient to be simultaneously available (Correct answer)

Correct answer: It allows the dietitian to review detailed records at a convenient time without requiring the patient to be simultaneously available

Asynchronous telehealth allows clinicians to review submitted information on their own schedule, improving efficiency and reducing patient burden of scheduled appointments.

Question 24: A dietitian reviews labs for a CKD patient taking herbal supplements. Elevated serum potassium with no dietary explanation is found. Which supplement class poses the greatest hyperkalemia risk?

Echinacea and St. John's Wort
Aloe vera and dandelion root (Correct answer)
Iron-containing herbal teas
Licorice root and star anise

Correct answer: Aloe vera and dandelion root

Aloe vera and dandelion are naturally high in potassium and are commonly used herbal remedies that significantly raise potassium intake in CKD patients.

Question 25: How does metabolic acidosis commonly develop in CKD patients?

Because of excessive vomiting.
From hyperventilation.
Due to increased bicarbonate production.
From reduced acid excretion and bicarbonate reabsorption (Correct answer)

Correct answer: From reduced acid excretion and bicarbonate reabsorption

Metabolic acidosis commonly develops in CKD patients because their impaired kidneys are less able to excrete hydrogen ions (acid) and regenerate or reabsorb bicarbonate. As kidney function declines, the body's buffering capacity is overwhelmed, leading to an accumulation of acid. This imbalance results in a decrease in blood pH, which is characteristic of metabolic acidosis.

Question 26: A renal dietitian notices that a patient's EHR growth chart shows unintentional weight loss over three consecutive months. Which next step best leverages digital tools to investigate the cause?

Discharge the patient to primary care
Order a DEXA scan without further investigation
Cross-reference the weight trend with lab values and dietary intake records documented in the EHR (Correct answer)
Increase the frequency of scheduled phone calls only

Correct answer: Cross-reference the weight trend with lab values and dietary intake records documented in the EHR

Cross-referencing weight trends with labs and dietary records within the EHR allows the dietitian to identify whether the loss is due to inadequate intake, fluid removal, or metabolic changes.

Question 27: The Subjective Global Assessment (SGA) tool used in renal patients primarily evaluates:

Body mass index, mid-arm circumference, and triceps skinfold measurements only
History of weight change, dietary intake changes, GI symptoms, functional capacity, and physical examination findings (Correct answer)
Serum albumin, prealbumin, and transferrin as primary nutritional biomarkers
Dialysis adequacy and fluid status as proxies for nutritional health

Correct answer: History of weight change, dietary intake changes, GI symptoms, functional capacity, and physical examination findings

SGA integrates clinical history (weight, diet, GI symptoms, function) with physical examination to classify nutritional status.

Question 28: Post-kidney transplant patients on calcineurin inhibitors (tacrolimus, cyclosporine) must avoid which specific food/drink due to potentially dangerous drug interactions?

White rice and white bread
Whole milk and dairy products
Grapefruit and grapefruit juice (Correct answer)
Lean chicken breast and fish

Correct answer: Grapefruit and grapefruit juice

Grapefruit and grapefruit juice contain furanocoumarins that inhibit intestinal CYP3A4 enzyme, which metabolizes calcineurin inhibitors. Inhibiting CYP3A4 increases drug bioavailability and blood levels, risking nephrotoxicity and immunosuppression toxicity.

Question 29: Which continuing education activity is most directly aligned with maintaining CSR competency in evidence-based practice?

Shadowing a nephrologist during clinic visits
Completing a cooking demonstration for low-potassium foods
Critically reviewing randomized controlled trials on protein intake in CKD patients (Correct answer)
Attending a pharmaceutical-sponsored dinner lecture on dialysis medications

Correct answer: Critically reviewing randomized controlled trials on protein intake in CKD patients

Critically evaluating primary research literature is the cornerstone of evidence-based practice competency for specialist practitioners.

Question 30: A renal dietitian notices a dialysis patient consistently avoids eye contact and gives one-word answers during counseling. Which approach is MOST appropriate?

Proceed with standard dietary education as planned
Refer the patient immediately to a social worker
Acknowledge the patient's body language and ask open-ended questions about their concerns (Correct answer)
Reschedule the session for a time when the patient seems more engaged

Correct answer: Acknowledge the patient's body language and ask open-ended questions about their concerns

Acknowledging non-verbal cues and using open-ended questions helps uncover barriers to engagement and builds therapeutic rapport.

Question 31: A scatter diagram comparing weekly dietary phosphorus intake (x-axis) to serum phosphorus levels (y-axis) shows a strong positive correlation. This means:

There is no meaningful relationship between diet and serum phosphorus
As dietary phosphorus increases, serum phosphorus tends to increase as well (Correct answer)
Serum phosphorus causes increased dietary phosphorus intake
High dietary phosphorus intake is the sole cause of elevated serum phosphorus

Correct answer: As dietary phosphorus increases, serum phosphorus tends to increase as well

A positive correlation indicates that both variables tend to move in the same direction, though correlation does not establish causation.

Question 32: A peritoneal dialysis patient has persistent hypomagnesemia (Mg 1.4 mEq/L). Which dietary counseling is appropriate?

Encourage adequate intake of magnesium-rich foods (nuts, seeds, legumes, whole grains) and consider oral magnesium supplementation after physician review (Correct answer)
Recommend magnesium-containing laxatives freely as they are safe in PD
Hypomagnesemia is not clinically significant in renal patients
Restrict all magnesium-containing foods as magnesium accumulates in dialysis

Correct answer: Encourage adequate intake of magnesium-rich foods (nuts, seeds, legumes, whole grains) and consider oral magnesium supplementation after physician review

PD patients can lose magnesium into dialysate, and dietary restriction of magnesium-rich foods (often also high in potassium/phosphorus) can cause hypomagnesemia. Low magnesium increases risk of cardiac arrhythmias, insulin resistance, and cardiovascular events in CKD.

Question 33: Intradialytic parenteral nutrition (IDPN) is MOST appropriate for which hemodialysis patient scenario?

Any dialysis patient with serum albumin below 3.5 g/dL
A patient who prefers parenteral over oral nutrition for convenience
A malnourished patient who cannot meet nutritional needs orally or via enteral supplementation (Correct answer)
A patient with adequate oral intake who refuses dietary counseling

Correct 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.

Question 34: A hemodialysis patient reports drinking 2.5 L of fluid daily despite a 1.5 L/day restriction. On dietary assessment, the dietitian finds that the patient is not counting soup, yogurt, ice cream, and frozen fruit as 'fluids.' What is the appropriate educational intervention?

Inform the patient that only liquids from a cup or glass count as 'fluid'
Revise the fluid restriction upward to accommodate the patient's actual intake
Educate the patient that ALL foods that are liquid at room temperature (soups, gelatin, ice cream, pudding, yogurt) AND high-water-content foods (watermelon, frozen fruit) must be counted as part of the fluid allowance (Correct answer)
No intervention needed as non-beverage fluids are not clinically significant

Correct answer: Educate the patient that ALL foods that are liquid at room temperature (soups, gelatin, ice cream, pudding, yogurt) AND high-water-content foods (watermelon, frozen fruit) must be counted as part of the fluid allowance

Any food that is liquid at room temperature (ice melts, gelatin melts, soups, ice cream) counts as fluid intake. Many patients incorrectly believe only beverages count. Hidden fluid sources routinely cause patients to significantly exceed prescribed limits.

Question 35: A 28-year-old female dialysis patient is pregnant. How do protein and energy requirements change during pregnancy in the dialysis setting?

Protein is restricted to <0.6 g/kg/day to prevent fetal uremia
Pregnancy on dialysis requires total parenteral nutrition only
Protein increases to 1.5–1.8 g/kg/day and energy to 35–40 kcal/kg/day; intensive daily dialysis (≥36 hours/week) is recommended to reduce uremic toxin exposure to the fetus (Correct answer)
Requirements are the same as non-pregnant dialysis patients

Correct answer: Protein increases to 1.5–1.8 g/kg/day and energy to 35–40 kcal/kg/day; intensive daily dialysis (≥36 hours/week) is recommended to reduce uremic toxin exposure to the fetus

Pregnancy on dialysis requires significantly increased protein (1.5–1.8 g/kg/day, adding ~20 g/day for fetal growth), higher energy intake (35–40 kcal/kg/day), intensive daily dialysis (36+ hours/week to reduce BUN < 50 mg/dL to minimize fetal uremia), and careful monitoring of all micronutrients.

Question 36: For a hemodialysis patient receiving 3× weekly treatment, what is the optimal timing for the largest protein/meal intake relative to the HD session?

After dialysis sessions (within 1–2 hours) to replenish amino acid losses and take advantage of post-dialysis anabolic window (Correct answer)
Timing of protein intake is irrelevant in HD patients
Restricted for 4 hours before dialysis and 4 hours after dialysis
Immediately before each dialysis session to maximize protein delivery

Correct answer: After dialysis sessions (within 1–2 hours) to replenish amino acid losses and take advantage of post-dialysis anabolic window

Post-dialysis is the optimal time for protein-rich meals because: (1) it replaces the 6–8 g amino acids lost in dialysate; (2) the dialysis session creates an acute catabolic state, and the immediate post-dialysis window (similar to post-exercise) is anabolically primed for protein synthesis.

Question 37: A dietitian notes a hemodialysis patient has consistently low predialysis serum creatinine values despite stable dialysis adequacy (Kt/V ≥ 1.4). What nutritional risk does this most likely indicate?

Loss of residual renal function
Aluminum accumulation from binder use
Excellent dialysis clearance reducing uremic toxins
Reduced muscle mass consistent with protein-energy wasting (Correct answer)

Correct answer: Reduced muscle mass consistent with protein-energy wasting

Low serum creatinine in dialysis patients often reflects reduced muscle mass and inadequate protein intake rather than improved clearance, signaling protein-energy wasting risk.

Question 38: Which statement BEST reflects the principle of cultural humility in renal nutrition counseling?

Learning a fixed set of dietary customs for each cultural group and applying them uniformly
Acknowledging one's own biases and engaging in ongoing learning about each patient's unique cultural context (Correct answer)
Deferring all cross-cultural counseling to a cultural liaison
Avoiding cultural topics to prevent assumptions

Correct answer: Acknowledging one's own biases and engaging in ongoing learning about each patient's unique cultural context

Cultural humility involves self-reflection and recognizing that individual patients' cultural contexts vary even within groups, unlike static cultural competency lists.

Question 39: When documenting a patient's dietary counseling session in the medical record, the renal dietitian should ensure the note:

Is objective, includes assessment, goals discussed, and the patient's response (Correct answer)
Reflects only positive interactions to encourage future engagement
Omits lab values to protect patient privacy within the chart
Includes personal opinions about the patient's motivation level

Correct answer: Is objective, includes assessment, goals discussed, and the patient's response

Objective, complete documentation supports continuity of care and reflects the professional standard for medical records.

Question 40: Cinacalcet (a calcimimetic) lowers PTH levels by activating which receptor on parathyroid gland cells?

Phosphate transporter
Vitamin D receptor
Calcium-sensing receptor (CaSR) (Correct answer)
Angiotensin receptor

Correct answer: Calcium-sensing receptor (CaSR)

Cinacalcet activates the calcium-sensing receptor on parathyroid cells, suppressing PTH secretion.

Question 41: What role does sodium play in managing renal disease patients?

Sodium has no impact.
Sodium aids kidney filtration.
Sodium should be increased.
Sodium restriction controls hypertension and edema. (Correct answer)

Correct answer: Sodium restriction controls hypertension and edema.

Sodium restriction plays a critical role in managing renal disease patients primarily by controlling hypertension and edema. Impaired kidneys struggle to excrete excess sodium, leading to fluid retention, which elevates blood pressure and causes swelling. Limiting sodium intake helps reduce fluid overload, thereby managing blood pressure and alleviating symptoms like edema and shortness of breath.

Question 42: For a non-dialysis CKD Stage 3–5 patient, what is the KDOQI-recommended energy intake to maintain neutral nitrogen balance?

40–45 kcal/kg/day ideal body weight
20–25 kcal/kg/day ideal body weight
30–35 kcal/kg/day ideal body weight (Correct answer)
15–20 kcal/kg/day ideal body weight

Correct answer: 30–35 kcal/kg/day ideal body weight

KDOQI 2020 recommends 25–35 kcal/kg IBW/day for CKD non-dialysis patients to maintain nitrogen balance and preserve body weight. The range of 30–35 kcal/kg/day is used for most adults; lower end applies to sedentary or overweight patients.

Question 43: In nephrotic syndrome, massive proteinuria leads to hypoalbuminemia and edema. What is the primary mechanism of edema formation?

Direct sodium retention by the renal tubules independent of oncotic pressure
Reduced plasma oncotic pressure leading to fluid shift into interstitium (Correct answer)
Increased lymphatic obstruction from protein accumulation
Increased capillary hydrostatic pressure from hypertension

Correct answer: Reduced plasma oncotic pressure leading to fluid shift into interstitium

Loss of albumin reduces plasma oncotic pressure (colloid osmotic pressure), allowing hydrostatic pressure to push fluid into the interstitial space, causing edema.

Question 44: Which measure can help evaluate the effectiveness of a renal nutrition intervention?

Body weight, serum albumin, and dietary intake (Correct answer)
Calcium supplements.
Serum glucose alone.
Urine color.

Correct answer: Body weight, serum albumin, and dietary intake

To evaluate the effectiveness of a renal nutrition intervention, a combination of measures is essential. Monitoring body weight helps assess fluid balance and overall energy status, while serum albumin levels reflect protein status and inflammation. Regular assessment of dietary intake ensures adherence to the prescribed plan and allows for adjustments, collectively providing a comprehensive picture of the intervention's impact on the patient's nutritional health.

Question 45: 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:

1.5–2.5 g/kg/day to compensate for CRRT-associated amino acid losses (Correct answer)
1.0 g/kg/day as standard ICU protein target regardless of CRRT
0.6–0.8 g/kg/day to minimize urea generation during kidney failure
Protein should be withheld until CRRT is discontinued

Correct 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.

Question 46: A patient with limited English proficiency needs education on potassium restriction. The renal dietitian should FIRST:

Use a qualified medical interpreter and culturally appropriate materials (Correct answer)
Delay education until the patient learns enough English
Provide materials in English and ask a bilingual family member to translate
Simplify the English instructions to basic vocabulary

Correct answer: Use a qualified medical interpreter and culturally appropriate materials

Using a qualified medical interpreter ensures accuracy and preserves patient confidentiality compared to using family members.

Question 47: Why is documentation important in CSR risk management?

It creates an audit trail and demonstrates due diligence (Correct answer)
It slows down critical operations
It only benefits legal teams during litigation
It is optional administrative work

Correct answer: It creates an audit trail and demonstrates due diligence

Documentation in risk management creates accountability, supports decision-making, and demonstrates professional due diligence.

Question 48: A CKD patient reports using a popular social media group for dietary advice and following recommendations that conflict with their prescribed renal diet. The dietitian should:

Tell the patient to immediately stop using social media for health advice
Report the social media group to the platform for providing medical misinformation
Only address advice that directly contradicts lab trends
Acknowledge the patient's peer support needs, evaluate specific claims for safety, and offer evidence-based alternatives (Correct answer)

Correct answer: Acknowledge the patient's peer support needs, evaluate specific claims for safety, and offer evidence-based alternatives

Acknowledging the appeal of peer support while critically evaluating specific advice helps the patient discern safe from harmful information without alienating them.

Question 49: A CKD patient is prescribed an ACE inhibitor and a potassium-sparing diuretic simultaneously. Which electrolyte risk requires urgent dietary counseling?

Hyponatremia from combined diuretic effect
Hypophosphatemia from renal phosphate wasting
Life-threatening hyperkalemia from additive potassium retention (Correct answer)
Hypocalcemia from ACE inhibitor interference

Correct answer: Life-threatening hyperkalemia from additive potassium retention

Both ACE inhibitors and potassium-sparing diuretics independently elevate serum potassium; their combination in CKD creates a high risk for dangerous hyperkalemia requiring immediate dietary potassium restriction.

Question 50: A peritoneal dialysis patient with residual kidney function has a GFR of 8 mL/min. How should protein recommendations differ from a standard HD patient with no residual function?

Protein needs may be slightly lower since residual function provides additional clearance (Correct answer)
Protein should be increased to 1.8 g/kg/day due to PD losses
Protein needs are identical regardless of residual kidney function
Protein should be restricted to 0.6 g/kg/day to protect residual function

Correct answer: Protein needs may be slightly lower since residual function provides additional clearance

Residual kidney function in PD patients contributes to overall solute clearance, which can modestly reduce the protein prescription compared to anuric PD patients.

Question 51: Calcium-phosphate product (Ca × P) is monitored in dialysis patients to assess risk of vascular calcification. What product value is generally associated with increased calcification risk?

Ca × P > 20 mg²/dL²
Ca × P > 55 mg²/dL² (Correct answer)
Ca × P > 75 mg²/dL²
Ca × P > 35 mg²/dL²

Correct answer: Ca × P > 55 mg²/dL²

A calcium-phosphate product > 55 mg²/dL² (older KDOQI threshold) is associated with increased risk of metastatic/vascular calcification (coronary arteries, heart valves, soft tissues) in dialysis patients. KDIGO 2017 moved away from strict targets but risk increases above this value.

Question 52: During an interdisciplinary care team meeting for a hemodialysis unit, the renal dietitian notices a discrepancy between their dietary recommendation and the nurse's instruction to the patient. The BEST action is to:

Correct the nurse in front of the patient to ensure accurate information
Defer entirely to the nurse's recommendation to preserve team harmony
Address the discrepancy directly with the nurse outside of the patient's presence and reach consensus (Correct answer)
Document the disagreement without addressing it verbally

Correct answer: Address the discrepancy directly with the nurse outside of the patient's presence and reach consensus

Addressing care discrepancies with colleagues privately maintains team respect and ensures the patient receives consistent, accurate guidance.

Question 53: Long-term kidney transplant recipients (>5 years) who have declining graft function (GFR 30–45 mL/min) should be managed nutritionally how?

Transition back toward CKD Stage 3b nutrition guidelines: moderate protein restriction (0.6–0.8 g/kg/day), phosphorus and potassium management, sodium restriction, and preparation for potential return to dialysis (Correct answer)
No dietary changes needed until GFR falls below 15 mL/min
Use the same nutrition guidelines as stable end-stage dialysis patients
Increase protein to 1.5 g/kg/day to prevent graft rejection

Correct answer: Transition back toward CKD Stage 3b nutrition guidelines: moderate protein restriction (0.6–0.8 g/kg/day), phosphorus and potassium management, sodium restriction, and preparation for potential return to dialysis

Declining transplant graft function recapitulates CKD pathophysiology. At GFR 30–45 mL/min (CKD Stage 3b), renal dietitian guidelines parallel native CKD Stage 3b: protein moderation (0.6–0.8 g/kg/day), electrolyte monitoring, and preparation for potential renal replacement therapy.

Question 54: A renal dietitian sets a follow-up goal with a patient, but the patient never returns for the scheduled visit. The MOST proactive response is to:

Wait for the patient to reschedule at their own convenience
Conduct an outreach call to assess barriers to attendance and offer alternative visit formats (Correct answer)
Discharge the patient from the caseload after one missed appointment
Notify the nephrologist of non-compliance without attempting patient contact

Correct answer: Conduct an outreach call to assess barriers to attendance and offer alternative visit formats

Proactive outreach to identify barriers (transportation, work schedule, cost) prevents dropout and supports patient-centered care.

Question 55: What is the MOST common cause of death in long-term kidney transplant recipients (beyond 1 year post-transplant)?

Cardiovascular disease (myocardial infarction, stroke) (Correct answer)
Acute rejection episodes
Return to dialysis from chronic rejection
Infectious complications from immunosuppression

Correct answer: Cardiovascular disease (myocardial infarction, stroke)

Cardiovascular disease (MI, stroke, congestive heart failure) is the leading cause of death in kidney transplant recipients beyond 1 year, accounting for 30–40% of deaths. Pre-existing CVD risk, post-transplant hypertension, dyslipidemia, NODAT, and obesity compound this risk.

Question 56: When conducting telehealth nutrition counseling for a rural CKD patient, the dietitian should prioritize which of the following?

Confirming the patient can see and hear clearly, then applying the same evidence-based counseling approach as in-person (Correct answer)
Shortening the session to reduce technology fatigue
Focusing only on written materials since visual demonstration is not possible via video
Avoiding discussion of lab values without a physical chart present

Correct answer: Confirming the patient can see and hear clearly, then applying the same evidence-based counseling approach as in-person

Telehealth counseling should match in-person quality; confirming audio/visual clarity is a prerequisite for effective remote communication.

Question 57: A CKD G4 patient develops vascular calcification on imaging. Which phosphate management strategy is MOST appropriate according to current guidelines?

Restrict protein intake to below 0.6 g/kg/day to reduce endogenous phosphorus
Increase calcium carbonate dose to maximize phosphate binding
Prescribe high-dose calcitriol to suppress PTH-driven calcification
Prioritize dietary phosphorus restriction and use calcium-free phosphate binders when needed (Correct answer)

Correct answer: Prioritize dietary phosphorus restriction and use calcium-free phosphate binders when needed

In CKD patients with vascular calcification, calcium-based binders should be avoided or minimized to prevent additional calcium loading; calcium-free binders (sevelamer, lanthanum) are preferred alongside dietary phosphorus restriction.

Question 58: A Stage 3 CKD patient in the pre-contemplation stage of behavior change is NOT yet considering dietary modification. The MOST appropriate dietitian response is to:

Discharge the patient from nutrition services until they are ready
Raise awareness of risks without pressuring change, and plant seeds for future readiness (Correct answer)
Report non-compliance to the nephrologist as non-adherence
Provide detailed meal plans and expect immediate compliance

Correct answer: Raise awareness of risks without pressuring change, and plant seeds for future readiness

Pre-contemplators are not ready for action; the role of the dietitian is to raise awareness and express concern without creating resistance.

Question 59: What distinguishes risk mitigation from risk avoidance in Board Certified Specialist in Renal Nutrition practice?

Mitigation is always preferred
Mitigation reduces impact or likelihood while avoidance eliminates the activity entirely (Correct answer)
Avoidance is never appropriate
They are identical concepts

Correct answer: Mitigation reduces impact or likelihood while avoidance eliminates the activity entirely

Risk mitigation allows the activity to continue with reduced risk, while avoidance eliminates the risk by not engaging in the activity at all.

Question 60: When calculating protein requirements for a peritoneal dialysis (PD) patient, which additional protein loss must be accounted for compared to hemodialysis patients?

Increased urinary protein from residual kidney function
Skin losses from uremic pruritus
Protein losses into peritoneal dialysate effluent (Correct answer)
Fecal protein losses from uremia-related diarrhea

Correct answer: Protein losses into peritoneal dialysate effluent

In PD, albumin and other proteins are continuously lost into the dialysate at approximately 5–15 g/day for CAPD patients. KDOQI recommends ≥ 1.2–1.3 g/kg/day protein for PD patients to account for these dialysate losses.

Question 61: The renin-angiotensin-aldosterone system (RAAS) is activated when renal perfusion pressure falls. Which renal cells are responsible for renin secretion?

Macula densa cells
Podocytes
Juxtaglomerular cells (Correct answer)
Mesangial cells

Correct answer: Juxtaglomerular cells

Juxtaglomerular (JG) cells in the afferent arteriole wall are specialized smooth muscle cells that synthesize, store, and secrete renin in response to reduced perfusion pressure.

Question 62: Which segment of the nephron is primarily responsible for the reabsorption of approximately 65% of filtered sodium?

Collecting duct
Proximal convoluted tubule (Correct answer)
Distal convoluted tubule
Loop of Henle

Correct answer: Proximal convoluted tubule

The proximal convoluted tubule reabsorbs roughly 65% of filtered sodium via sodium-hydrogen exchangers and sodium-coupled transporters, making it the nephron's primary sodium reabsorption site.

Question 63: A hemodialysis patient's normalized protein catabolic rate (nPCR) drops from 1.1 to 0.7 g/kg/day over 3 months. What nutritional risk does this trend indicate?

Increased muscle anabolism from exercise
Improved metabolic control from dietary adherence
Protein-energy wasting and inadequate dietary intake (Correct answer)
Excessive protein intake leading to uremia

Correct answer: Protein-energy wasting and inadequate dietary intake

A declining nPCR below 1.0 g/kg/day in hemodialysis patients signals inadequate protein intake and is a marker of protein-energy wasting risk.

Question 64: Which of the following dietary interventions has the strongest evidence for slowing CKD progression in non-dialysis CKD patients?

High-protein diet (>1.5 g/kg/day) to prevent muscle wasting
Very high sodium intake to maintain blood pressure
Ketogenic diet eliminating all carbohydrates
Low-protein diet (0.6–0.8 g/kg/day) to reduce hyperfiltration and uremic toxin load (Correct answer)

Correct answer: Low-protein diet (0.6–0.8 g/kg/day) to reduce hyperfiltration and uremic toxin load

Low-protein diets (0.6–0.8 g/kg/day) reduce intraglomerular pressure (by decreasing hyperfiltration), lower the uremic toxin load, and decrease proteinuria, collectively slowing CKD progression according to multiple meta-analyses and KDIGO guidelines.

Question 65: How do CSR professionals evaluate the quality of research evidence?

By the publication date alone
Research quality cannot be meaningfully evaluated
By assessing methodology, sample size, peer review, and relevance (Correct answer)
By the prestige of the author or institution

Correct answer: By assessing methodology, sample size, peer review, and relevance

Evaluating research quality requires examining the methodology, sample characteristics, peer review process, and relevance to the specific practice context.

Question 66: In the context of CKD, 'uremia' refers to a clinical syndrome resulting from accumulation of which substances?

Overflow of urine components into the bloodstream due to kidney rupture
Retention of nitrogenous waste products and other uremic solutes normally excreted by the kidneys (Correct answer)
Excess dietary protein consumed by the patient
Bacterial contamination of the urinary tract

Correct answer: Retention of nitrogenous waste products and other uremic solutes normally excreted by the kidneys

Uremia is the clinical syndrome caused by accumulation of nitrogen-containing waste products (urea, creatinine, uric acid) and other uremic solutes (organic acids, guanidines, protein-bound toxins) when kidney excretion fails.

Question 67: Malnutrition-inflammation complex syndrome (MICS) in dialysis patients is characterized by which combination of findings?

High albumin and low C-reactive protein
Fluid overload and hypernatremia
Elevated phosphorus and suppressed PTH
Low albumin, elevated CRP, and progressive muscle wasting (Correct answer)

Correct answer: Low albumin, elevated CRP, and progressive muscle wasting

MICS involves concurrent protein-energy malnutrition and chronic inflammation, reflected by low albumin, elevated CRP, and muscle loss.

Question 68: When assessing cardiovascular risk in a CKD patient, an elevated serum FGF-23 level is most directly associated with which adverse outcome?

Accelerated iron deficiency anemia
Worsening hyperphosphatemia from gut absorption
Left ventricular hypertrophy and cardiovascular mortality (Correct answer)
Increased risk of hyperkalemia

Correct answer: Left ventricular hypertrophy and cardiovascular mortality

Elevated FGF-23 is independently associated with left ventricular hypertrophy and increased cardiovascular mortality in CKD patients, beyond its role in phosphate regulation.

Question 69: Which of the following BEST describes 'reflective listening' as used in renal nutrition counseling?

Summarizing clinical data from the chart back to the patient
Paraphrasing the patient's statement to demonstrate understanding and invite elaboration (Correct answer)
Asking the patient to reflect on their dietary choices after each session
Repeating the patient's words verbatim to confirm what was heard

Correct answer: Paraphrasing the patient's statement to demonstrate understanding and invite elaboration

Reflective listening involves paraphrasing the patient's meaning to validate their experience and encourage deeper exploration of their thoughts and feelings.

Question 70: Which dietary pattern has been shown to slow CKD progression and reduce cardiovascular risk in early-stage CKD?

High-protein, low-carbohydrate ketogenic diet
Mediterranean diet with fish excluded to reduce phosphorus
Standard American diet with protein restriction only
DASH diet modified for lower potassium and phosphorus content (Correct answer)

Correct answer: DASH diet modified for lower potassium and phosphorus content

A modified DASH diet—adjusted for CKD-specific mineral restrictions—supports blood pressure control and has evidence for slowing CKD progression.

Question 71: What does the ethical principle of beneficence entail in renal nutrition care?

Doing no harm.
Respecting patient privacy.
Acting in the patient’s best interest. (Correct answer)
Treating all patients equally.

Correct answer: Acting in the patient’s best interest.

Beneficence is an ethical principle that requires healthcare professionals to act in ways that benefit the patient and promote their well-being. In renal nutrition care, this means providing interventions and advice that are intended to improve the patient's health, prevent harm, and optimize their nutritional status, always with their best interests as the primary goal.

Question 72: What is the value of active listening in CSR professional practice?

It simply means remaining silent while others speak
It is only important in counseling roles
It unnecessarily slows down conversations
It ensures accurate understanding and demonstrates respect for the speaker (Correct answer)

Correct answer: It ensures accurate understanding and demonstrates respect for the speaker

Active listening in CSR practice ensures accurate understanding, builds trust, and demonstrates respect, leading to better professional outcomes.

Question 73: A renal dietitian receives a voicemail from a patient's adult child asking for detailed lab results and dietary information. The dietitian should:

Provide general guidance only, with no patient-specific details
Ask the nephrologist to handle the call instead
Call back and share all information to support the caregiver's involvement
Verify that a signed HIPAA authorization from the patient is on file before sharing any information (Correct answer)

Correct answer: Verify that a signed HIPAA authorization from the patient is on file before sharing any information

HIPAA requires patient authorization before sharing protected health information with family members, regardless of their caregiving role.

Question 74: Which hemodialysis frequency allows the greatest dietary fluid liberalization due to more frequent fluid removal?

Daily hemodialysis (6×/week) (Correct answer)
CRRT in ICU setting
Conventional hemodialysis (3×/week)
Peritoneal dialysis (4 exchanges/day)

Correct answer: Daily hemodialysis (6×/week)

Daily hemodialysis allows more fluid removal sessions per week, enabling a more liberal daily fluid intake allowance.

Question 75: Vitamin C supplementation exceeding 100 mg/day in CKD patients increases the risk of accumulation of which substance?

Oxalate (Correct answer)
Uric acid
Creatinine
Phosphate

Correct answer: Oxalate

Excess vitamin C is metabolized to oxalate, which can accumulate dangerously in CKD patients with reduced excretion capacity.

Question 76: Secondary hyperparathyroidism in CKD develops due to which combination of metabolic disturbances?

Hyperkalemia and hypernatremia
Hypocalcemia, hyperphosphatemia, and reduced calcitriol synthesis (Correct answer)
Metabolic alkalosis and hypercalcemia
Hypomagnesemia and vitamin B12 deficiency

Correct answer: Hypocalcemia, hyperphosphatemia, and reduced calcitriol synthesis

Reduced nephron mass decreases calcitriol (1,25-OH2 vitamin D) production and phosphate excretion. Hyperphosphatemia lowers ionized calcium. Together, hypocalcemia and low calcitriol stimulate PTH synthesis and parathyroid hyperplasia.

Question 77: A renal dietitian wants to assess whether a new protein-restricted diet app improves dietary adherence in CKD patients compared to standard counseling using a crossover design. A key advantage of this design is:

It requires a larger sample than a parallel-group RCT
Each participant serves as their own control, reducing variability due to individual differences (Correct answer)
It eliminates the need for informed consent
It is ideal when the disease condition is irreversible

Correct answer: Each participant serves as their own control, reducing variability due to individual differences

In a crossover design, within-subject comparisons control for individual differences, increasing statistical efficiency and reducing required sample size.

Question 78: What is reflective practice in Board Certified Specialist in Renal Nutrition professional growth?

Maintaining a personal journal unrelated to work
Simply avoiding past mistakes
Systematically examining experiences to gain insight and improve future practice (Correct answer)
Reflecting only on positive outcomes and successes

Correct answer: Systematically examining experiences to gain insight and improve future practice

Reflective practice involves systematically examining both successes and failures to extract insights that improve future professional performance.

Question 79: Which validated formula is used to estimate protein and energy needs when indirect calorimetry is unavailable in a hospitalized dialysis patient?

Harris-Benedict equation using standard activity factor
Body weight × fixed 25 kcal/kg regardless of clinical condition
Only indirect calorimetry provides valid estimates in dialysis
Modified Harris-Benedict or Mifflin-St Jeor equation adjusted to IBW or dry weight, with a stress factor of 1.0–1.3 depending on clinical status (Correct answer)

Correct answer: Modified Harris-Benedict or Mifflin-St Jeor equation adjusted to IBW or dry weight, with a stress factor of 1.0–1.3 depending on clinical status

Predictive equations (Modified Harris-Benedict, Mifflin-St Jeor) using adjusted/ideal body weight provide reasonable energy estimates when indirect calorimetry is unavailable. Stress factors (1.0–1.3) account for clinical condition (stable, mild infection, severe illness).

Question 80: A renal dietitian is conducting a mixed-methods study on dietary adherence barriers in hemodialysis patients. The qualitative component involves thematic analysis of patient interviews. What is the primary advantage of including qualitative data in this renal nutrition study?

It allows calculation of relative risk for non-adherence
It provides in-depth understanding of patients' lived experiences and contextual barriers (Correct answer)
It increases the statistical power of the study
It eliminates the need for a control group

Correct answer: It provides in-depth understanding of patients' lived experiences and contextual barriers

Qualitative methods capture nuanced patient perspectives, motivations, and contextual factors that quantitative measures alone cannot reveal.

Question 81: A CKD patient with diabetes develops an ABI (ankle-brachial index) of 0.7. Which nutritional intervention is most directly indicated to mitigate associated wound healing risk?

Adequate protein and calorie provision with micronutrient repletion (Correct answer)
Phosphate restriction to improve vascular calcification
Sodium restriction to reduce peripheral edema
Fluid restriction to reduce cardiovascular preload

Correct answer: Adequate protein and calorie provision with micronutrient repletion

Peripheral artery disease (ABI <0.9) impairs tissue perfusion; adequate protein, calories, zinc, vitamin C, and vitamin A are critical nutritional supports for wound healing risk mitigation.

Question 82: A patient tells the renal dietitian, 'My previous dietitian told me I could eat as much protein as I want.' The BEST initial response is:

Acknowledge the discrepancy, ask what stage the patient was at previously, and clarify current recommendations in context (Correct answer)
Agree with the previous advice to avoid damaging the patient-provider relationship
Document the previous dietitian's error and report it to the department
Immediately contradict the previous dietitian and explain the correct guidelines

Correct answer: Acknowledge the discrepancy, ask what stage the patient was at previously, and clarify current recommendations in context

Protein recommendations change with CKD stage and dialysis status, so contextualizing the discrepancy builds trust and prevents confusion.

Question 83: Which parameter is crucial in assessing protein-energy wasting (PEW) in CKD?

Blood glucose.
Hemoglobin.
Serum albumin (Correct answer)
Potassium levels.

Correct answer: Serum albumin

Serum albumin is a crucial parameter in assessing protein-energy wasting (PEW) in CKD because it is a major protein synthesized by the liver and serves as a marker of visceral protein status. Low serum albumin levels often indicate inadequate protein intake, inflammation, or fluid overload, all of which are common in PEW. These factors contribute to poor outcomes in CKD patients.

Question 84: A CKD patient has laboratory values showing low zinc levels. What is the MOST likely contributing factor related to renal disease?

Excessive dietary zinc intake causing competitive absorption block
Phosphate binders chelating zinc and preventing absorption
Reduced appetite leading to poor dietary intake plus increased urinary losses (Correct answer)
High dietary fiber binding zinc in the gut

Correct answer: Reduced appetite leading to poor dietary intake plus increased urinary losses

CKD patients commonly have low zinc due to anorexia reducing dietary intake, combined with increased urinary zinc losses in earlier CKD stages.

Question 85: A patient's phosphorus levels remain elevated despite reported dietary compliance. Before concluding the patient is non-adherent, the dietitian should FIRST:

Request a social work consultation for suspected self-sabotage
Explore potential hidden phosphorus sources (food additives, medications) and reassess the patient's understanding of portion sizes (Correct answer)
Recommend increasing phosphate binder dosage without further dietary assessment
Schedule a more intensive counseling session to reinforce phosphorus education

Correct answer: Explore potential hidden phosphorus sources (food additives, medications) and reassess the patient's understanding of portion sizes

Phosphate additives in processed foods and binder timing issues are common hidden causes of elevated phosphorus despite reported dietary adherence.

Question 86: During a nutrition-focused physical exam on a peritoneal dialysis patient, the dietitian observes temporal wasting, decreased grip strength, and loss of interosseous muscle. These findings collectively suggest which risk?

Peripheral neuropathy from B12 deficiency
Hyperphosphatemia-related bone disease manifestation
Fluid overload masking true body weight
Severe protein-energy wasting requiring urgent intervention (Correct answer)

Correct answer: Severe protein-energy wasting requiring urgent intervention

Temporal muscle wasting, interosseous muscle loss, and reduced grip strength are clinical signs of severe protein-energy wasting that indicate high nutritional risk and mortality.

Question 87: When identifying nutritional risk in CKD patients, which combination of lab values is most consistent with protein-energy wasting (PEW)?

Low albumin, high phosphorus, high potassium
Normal albumin, high BUN, low bicarbonate
Low albumin, low prealbumin, low serum creatinine (Correct answer)
High albumin, high creatinine, high BUN

Correct answer: Low albumin, low prealbumin, low serum creatinine

PEW is characterized by low albumin, low prealbumin, and paradoxically low serum creatinine due to reduced muscle mass and protein intake in CKD.

Question 88: Which lab value is most useful in assessing renal function?

Hemoglobin level.
Serum potassium.
Serum calcium.
Serum creatinine (Correct answer)

Correct answer: Serum creatinine

Serum creatinine is the most widely used lab value for assessing renal function because it is a waste product of muscle metabolism primarily filtered by the kidneys. As kidney function declines, creatinine accumulates in the blood, leading to elevated serum levels. This makes it a reliable marker for estimating glomerular filtration rate (GFR) and monitoring kidney health.

Question 89: In the context of renal nutrition QI, 'benchmarking' refers to:

Conducting unannounced audits of dietary counseling documentation
Comparing a facility's performance metrics against best practices or peer facilities (Correct answer)
Ranking individual dietitians by patient outcome scores
Setting the minimum acceptable standard for one facility's performance

Correct answer: Comparing a facility's performance metrics against best practices or peer facilities

Benchmarking involves comparing performance data against external standards or high-performing organizations to identify improvement opportunities.

Question 90: During a nutrition assessment, a hemodialysis patient reports eating a protein supplement between sessions. Her nPCR is 1.4 g/kg/day but she has persistent hyperphosphatemia. What is the MOST likely issue?

She is not eating enough protein to meet her needs
Her dialysis dose is inadequate and needs prescription adjustment
Her high protein intake from supplements may be contributing to phosphorus load (Correct answer)
She should switch to a lower calorie diet to reduce overall intake

Correct answer: Her high protein intake from supplements may be contributing to phosphorus load

High protein intakes, especially from supplements containing phosphorus additives, can worsen hyperphosphatemia even when phosphate binders are prescribed.

Question 91: What is a corrective action in Board Certified Specialist in Renal Nutrition quality systems?

Punishing individuals for errors
Ignoring minor quality deviations
Implementing only temporary fixes
A systematic response to eliminate causes of nonconformity and prevent recurrence (Correct answer)

Correct answer: A systematic response to eliminate causes of nonconformity and prevent recurrence

Corrective actions address root causes of quality issues to prevent recurrence, going beyond temporary fixes to create lasting improvement.

Question 92: Which anthropometric measurement is MOST useful for assessing nutritional status in a dialysis patient with significant fluid overload?

Waist circumference
Body mass index (BMI)
Mid-arm muscle circumference (MAMC) (Correct answer)
Body weight (measured at any time)

Correct answer: Mid-arm muscle circumference (MAMC)

In dialysis patients, body weight and BMI are confounded by fluid status. Mid-arm muscle circumference (MAMC), derived from mid-arm circumference and triceps skinfold, reflects somatic protein stores independent of fluid balance.

Question 93: A renal dietitian is asked to complete a nutritional assessment for a CKD patient who speaks only Spanish and has limited health literacy. Which of the following is the BEST approach to ensure valid informed consent for dietary intervention?

Use a bilingual family member to translate the consent form to save time
Defer the assessment until the patient learns English
Conduct the assessment in English and assume the patient understands
Provide a certified medical interpreter and use plain-language, back-translated materials in Spanish (Correct answer)

Correct answer: Provide a certified medical interpreter and use plain-language, back-translated materials in Spanish

Valid informed consent requires the patient to understand the information. Using a certified medical interpreter (not a family member) and culturally appropriate plain-language materials ensures accurate communication and protects patient autonomy and legal compliance under Title VI of the Civil Rights Act.

Question 94: A renal dietitian is developing discharge education for a patient transitioning from acute kidney injury (AKI) to outpatient CKD care. The PRIORITY nutrition topic for the first outpatient visit is:

Focusing exclusively on fluid restriction until GFR stabilizes
Initiating a 40g protein diet as standard post-AKI protocol
Continuing the strict AKI dietary restrictions regardless of recovered kidney function
Reassessing nutritional status and adjusting dietary restrictions based on current GFR and labs (Correct answer)

Correct answer: Reassessing nutritional status and adjusting dietary restrictions based on current GFR and labs

Post-AKI nutritional needs change as kidney function recovers, requiring individualized reassessment rather than continuation of acute-phase restrictions.

Question 95: What is the recommended daily protein intake for a stable adult hemodialysis patient per KDOQI guidelines?

1.2–1.4 g/kg/day (Correct answer)
0.6–0.8 g/kg/day
0.8–1.0 g/kg/day
1.5–2.0 g/kg/day

Correct answer: 1.2–1.4 g/kg/day

Hemodialysis patients require 1.2–1.4 g/kg/day of protein to compensate for dialysis-related catabolism and amino acid losses.

Question 96: Which gastrointestinal complication is MOST common in infants on peritoneal dialysis and directly impacts feeding tolerance and nutritional status?

Celiac disease triggered by dialysate components
Inflammatory bowel disease from uremia
Gastroesophageal reflux (GERD) and delayed gastric emptying exacerbated by increased intra-abdominal pressure from PD fluid, causing vomiting and feeding intolerance (Correct answer)
Pyloric stenosis from high-protein formula use

Correct answer: Gastroesophageal reflux (GERD) and delayed gastric emptying exacerbated by increased intra-abdominal pressure from PD fluid, causing vomiting and feeding intolerance

Peritoneal dialysis fluid fills the abdominal cavity, increasing intra-abdominal pressure. In infants (who have a large abdomen-to-body ratio), this exacerbates GERD and delays gastric emptying, causing frequent vomiting and poor feeding tolerance — a major contributor to growth failure.

Question 97: Which assessment finding in a new hemodialysis patient most strongly warrants referral for nutritional support beyond standard renal diet counseling?

Serum phosphorus of 5.5 mg/dL with good appetite
Serum potassium of 5.2 mEq/L on first post-dialysis labs
BMI of 27 with stable weight over 6 months
Unintentional weight loss >5% in 3 months with albumin <3.5 g/dL (Correct answer)

Correct answer: Unintentional weight loss >5% in 3 months with albumin <3.5 g/dL

Significant unintentional weight loss combined with hypoalbuminemia meets criteria for severe protein-energy wasting and requires intensive nutritional intervention beyond standard counseling.

Question 98: For a non-dialysis CKD Stage 4 patient with peripheral edema and mild hypertension, what is the MOST appropriate non-pharmacological intervention?

Dietary potassium restriction only
High sodium intake to maintain intravascular volume
Sodium restriction to < 2.3 g/day (100 mEq/day), combined with leg elevation and moderate physical activity to improve venous return (Correct answer)
Complete fluid restriction to 500 mL/day

Correct answer: Sodium restriction to < 2.3 g/day (100 mEq/day), combined with leg elevation and moderate physical activity to improve venous return

In CKD Stage 4 with edema, sodium restriction (< 2.3 g/day) is the cornerstone non-pharmacological intervention. Sodium drives water retention through osmotic and hormonal mechanisms. Leg elevation and physical activity support venous return. Strict fluid restriction alone without sodium restriction is less effective.

Question 99: What is the primary goal of a nutrition assessment in CKD?

To diagnose CKD.
To prescribe medications.
To replace medical treatment.
To create a personalized nutrition care plan (Correct answer)

Correct answer: To create a personalized nutrition care plan

The primary goal of a nutrition assessment in CKD is to gather comprehensive information about the patient's dietary intake, nutritional status, and medical history. This detailed assessment allows the renal dietitian to identify specific nutritional needs, potential deficiencies or excesses, and ultimately develop a personalized nutrition care plan. This plan aims to manage symptoms, slow disease progression, and improve overall quality of life.

Question 100: In the context of CKD mineral and bone disorder (CKD-MBD), fibroblast growth factor 23 (FGF-23) plays a key role in mineral metabolism. Which of the following correctly describes FGF-23's action?

FGF-23 activates osteoclasts, causing bone resorption and hypercalcemia
FGF-23 inhibits 1α-hydroxylase (reducing calcitriol) and promotes phosphaturia; elevated in CKD as a compensatory response to phosphate retention (Correct answer)
FGF-23 directly stimulates PTH release from the parathyroid gland
FGF-23 stimulates 1α-hydroxylase in the kidney, increasing calcitriol production

Correct answer: FGF-23 inhibits 1α-hydroxylase (reducing calcitriol) and promotes phosphaturia; elevated in CKD as a compensatory response to phosphate retention

FGF-23 is secreted by osteocytes in response to phosphate loading. It inhibits renal 1α-hydroxylase (reducing calcitriol), reduces sodium-phosphate cotransporter expression in the proximal tubule (promoting phosphaturia), and is markedly elevated in CKD as kidneys fail to respond.

Question 101: A hemodialysis patient with a body mass index of 38 kg/m² and serum albumin of 4.1 g/dL reports excellent appetite but has persistent interdialytic weight gains of 5-6 kg. What is the MOST appropriate nutritional focus?

Reduce total calorie intake by 50% to promote weight loss
Encourage increased dietary phosphorus to support cardiovascular health
Increase protein intake to prevent future malnutrition risk
Implement sodium restriction to reduce thirst and fluid consumption between sessions (Correct answer)

Correct answer: Implement sodium restriction to reduce thirst and fluid consumption between sessions

Excessive interdialytic weight gain is primarily driven by sodium intake, which stimulates thirst; restricting dietary sodium is the most direct dietary intervention.

Question 102: In dialysis patients, 'rebound hyperkalemia' can occur within hours after dialysis. Which physiological mechanism PRIMARILY explains this phenomenon?

Increased dietary potassium absorption due to post-dialysis hunger
Rapid re-absorption of potassium from the gut after dialysis
Shift of potassium from the intracellular compartment back to the extracellular space following removal of dialysis-induced alkalosis effects (Correct answer)
Residual kidney function secreting potassium back into the blood

Correct answer: Shift of potassium from the intracellular compartment back to the extracellular space following removal of dialysis-induced alkalosis effects

During dialysis, potassium is removed rapidly from plasma, but intracellular potassium equilibrates slowly. Post-dialysis, the electrochemical gradient drives K+ back from the intracellular compartment to plasma (rebound). Correction of dialysis-induced alkalosis also shifts K+ back extracellularly.

Question 103: How do CSR professionals build credibility with clients?

Through aggressive marketing alone
By always agreeing with client requests
Through competitive pricing exclusively
Through consistent competence, transparency, and ethical behavior over time (Correct answer)

Correct answer: Through consistent competence, transparency, and ethical behavior over time

Professional credibility is built through demonstrated competence, transparent communication, ethical conduct, and reliable delivery over time.

Question 104: What is a common dietary intervention for hyperphosphatemia in CKD?

Add more potassium-rich foods.
Reduce phosphorus intake (Correct answer)
Increase dairy intake.
Avoid carbohydrates.

Correct answer: Reduce phosphorus intake

A common and essential dietary intervention for hyperphosphatemia in CKD is to reduce phosphorus intake. As kidney function declines, the kidneys cannot adequately excrete phosphorus, leading to its accumulation in the blood. Limiting high-phosphorus foods helps control serum phosphorus levels, which is crucial for preventing bone disease and cardiovascular complications associated with CKD.

Question 105: Which vitamin is CONTRAINDICATED as a supplement (in standard doses) in CKD patients due to its accumulation causing increased risk of oxalosis and renal stone formation?

Vitamin E
Vitamin B12
Vitamin C (ascorbic acid) (Correct answer)
Vitamin D

Correct answer: Vitamin C (ascorbic acid)

In CKD, supplemental vitamin C (> 60–100 mg/day) should be avoided because impaired renal excretion causes oxalate accumulation (vitamin C is metabolized to oxalate), potentially worsening CKD progression and causing systemic oxalosis.

Question 106: Which antihypertensive drug class can significantly increase serum potassium by reducing aldosterone secretion in CKD patients?

Loop diuretics
Calcium channel blockers
ACE inhibitors (Correct answer)
Thiazide diuretics

Correct answer: ACE inhibitors

ACE inhibitors reduce aldosterone secretion, leading to potassium retention and increased hyperkalemia risk in CKD.

Question 107: A renal dietitian is counseling a patient newly diagnosed with IgA nephropathy and proteinuria of 2.5 g/day. Which protein recommendation is MOST appropriate at GFR 55 mL/min?

High protein intake of 1.8 g/kg/day to replace urinary losses
Very low protein diet of 0.3 g/kg/day with keto-acid supplementation
Moderate protein intake of approximately 0.8 g/kg/day to slow progression without causing malnutrition (Correct answer)
No protein restriction is needed until GFR falls below 30 mL/min

Correct answer: Moderate protein intake of approximately 0.8 g/kg/day to slow progression without causing malnutrition

Current guidelines recommend moderate protein restriction (0.8 g/kg/day) for CKD patients with proteinuria to slow progression while maintaining nutritional adequacy.

Question 108: In a renal nutrition study, researchers report a statistically significant result (p=0.03) but a mean serum phosphorus reduction of only 0.2 mg/dL. What concept best explains why this finding may not be clinically meaningful?

Type I error inflation
Lack of statistical power
Difference between statistical and clinical significance (Correct answer)
Regression to the mean

Correct answer: Difference between statistical and clinical significance

Statistical significance indicates a result unlikely due to chance, but clinical significance requires the effect size to be large enough to matter in patient care.

Question 109: A dietitian reads a systematic review in which a funnel plot is asymmetrical. What does funnel plot asymmetry typically suggest in a meta-analysis?

High heterogeneity in patient populations
The pooled effect estimate is unbiased
All included studies had large sample sizes
Possible publication bias or small-study effects (Correct answer)

Correct answer: Possible publication bias or small-study effects

Funnel plot asymmetry, where small studies cluster on one side, often signals publication bias or small-study effects that can inflate pooled estimates.

Question 110: A patient with CKD Stage 5 (GFR 8 mL/min) who is not yet on dialysis has severe uremic symptoms and a serum potassium of 6.5 mEq/L. In addition to urgent potassium-lowering measures, what dietary recommendation is MOST critical?

Increase fluid intake to 3 L/day to flush potassium through residual kidney function
Enforce strict potassium restriction (<1500 mg/day) while expediting nephrology referral for dialysis initiation discussion (Correct answer)
Immediately start a high-protein diet to prevent catabolism during illness
Stop all dietary restrictions and allow the patient to eat freely for comfort

Correct answer: Enforce strict potassium restriction (<1500 mg/day) while expediting nephrology referral for dialysis initiation discussion

At Stage 5 with severe hyperkalemia (K+ ≥ 6.5 mEq/L), strict potassium restriction (< 1500–2000 mg/day) is urgent to prevent life-threatening cardiac arrhythmias, while simultaneously coordinating with nephrology for timely dialysis initiation.

Question 111: Which of the following BEST describes the nutritional role of L-carnitine in hemodialysis patients?

L-carnitine is only necessary in vegetarian dialysis patients
L-carnitine supplementation is equivalent to protein supplementation for preventing PEW
L-carnitine supplementation is contraindicated in all dialysis patients due to accumulation
L-carnitine is removed by HD and may be depleted; supplementation (IV post-HD or oral) may improve HD-related fatigue, muscle weakness, cramps, and anemia non-responsive to ESA therapy (Correct answer)

Correct answer: L-carnitine is removed by HD and may be depleted; supplementation (IV post-HD or oral) may improve HD-related fatigue, muscle weakness, cramps, and anemia non-responsive to ESA therapy

L-carnitine is essential for mitochondrial fatty acid oxidation. HD removes carnitine each session, and renal synthesis is impaired in CKD. IV L-carnitine (20 mg/kg post-HD) may improve carnitine-deficiency symptoms including fatigue, dialysis-related hypotension, muscle cramps, and EPO-resistant anemia.

Question 112: In a renal nutrition RCT, 20% of participants in the intervention group withdrew due to dietary intolerance. This differential dropout could result in which type of bias?

Detection bias
Performance bias
Reporting bias
Attrition bias (Correct answer)

Correct answer: Attrition bias

Attrition bias occurs when differential or systematic loss of participants from study groups distorts the comparison of outcomes.

Question 113: During care planning for a CKD patient with advanced diabetes, the dietitian identifies gastroparesis. Which nutritional risk does gastroparesis most directly create in this population?

Excessive caloric absorption from delayed gastric emptying
Unpredictable carbohydrate absorption leading to glucose instability and malnutrition (Correct answer)
Increased phosphorus absorption from prolonged food-gut contact
Hyperkalemia from bacterial fermentation of undigested food

Correct answer: Unpredictable carbohydrate absorption leading to glucose instability and malnutrition

Gastroparesis causes erratic gastric emptying, making carbohydrate timing unpredictable, leading to postprandial hypoglycemia or hyperglycemia and progressive malnutrition from food avoidance.

Question 114: When tracking hemodialysis patient nutrition outcomes for QI purposes, which measure is considered a 'process measure' rather than an 'outcome measure'?

30-day hospitalization rate
Percentage of patients receiving monthly nutrition assessment (Correct answer)
Mortality rate
Serum albumin level

Correct answer: Percentage of patients receiving monthly nutrition assessment

Process measures assess whether recommended care activities are performed (e.g., completing assessments), while outcome measures assess the results of care.

Question 115: Which dietary pattern poses the greatest acute hyperkalemia risk for a hemodialysis patient who misses a dialysis session?

Excessive fluid intake between sessions
High-fat meal from fast food sources
Consumption of salt substitutes containing potassium chloride (Correct answer)
High intake of refined white carbohydrates

Correct answer: Consumption of salt substitutes containing potassium chloride

Salt substitutes replace sodium with potassium chloride and can deliver a large acute potassium load, critically dangerous if a dialysis session is missed.

Question 116: A renal dietitian is communicating with a patient who has low health literacy. Which strategy is MOST effective?

Using plain language, visual aids, and limiting information to 2-3 key messages per visit (Correct answer)
Speaking more slowly and repeating the same information louder
Providing detailed brochures with comprehensive clinical data
Referring the patient to online resources for independent learning

Correct answer: Using plain language, visual aids, and limiting information to 2-3 key messages per visit

Plain language, visuals, and limiting key messages per session are evidence-based strategies for effective communication with low health literacy patients.

Question 117: How do continuing education requirements benefit CSR certified professionals?

They are unnecessary formalities
They ensure professionals stay current with evolving industry practices (Correct answer)
They reduce practical skills over time
They only benefit training providers

Correct answer: They ensure professionals stay current with evolving industry practices

Continuing education ensures CSR professionals maintain current knowledge, adapt to industry changes, and continuously improve their practice.

Question 118: Which SMART goal is MOST appropriate for a hemodialysis patient struggling with interdialytic weight gain?

Stop drinking anything other than water
Limit fluid intake to 32 oz daily and track intake in a log for 2 weeks (Correct answer)
Try to be better about fluid restriction
Drink less fluid every day

Correct answer: Limit fluid intake to 32 oz daily and track intake in a log for 2 weeks

A SMART goal is Specific, Measurable, Achievable, Relevant, and Time-bound — setting a specific volume with a tracking method and timeframe meets all criteria.

Question 119: What is the primary function of the glomerulus in the nephron?

Concentrates urine.
Secretes erythropoietin.
Filters blood to form primary urine (Correct answer)
Reabsorbs electrolytes.

Correct answer: Filters blood to form primary urine

The glomerulus is a network of tiny blood vessels (capillaries) located at the beginning of a nephron in the kidney. Its primary function is ultrafiltration, where blood plasma, excluding large proteins and blood cells, is filtered from the capillaries into Bowman's capsule. This process forms the initial filtrate, or primary urine, which then proceeds through the rest of the nephron for further processing.

Question 120: The KDIGO 2024 CKD guidelines recommend which blood pressure target for most non-dialysis CKD patients to slow progression?

< 150/90 mmHg
< 120/70 mmHg
< 130/80 mmHg (Correct answer)
< 140/90 mmHg

Correct answer: < 130/80 mmHg

KDIGO 2024 recommends a blood pressure target of < 120 mmHg systolic (standardized office BP) for most CKD patients based on the SPRINT trial data, though < 130/80 mmHg is the commonly applied clinical target in routine practice.

Question 121: In telehealth-delivered MNT for CKD patients, which barrier is most likely to disproportionately affect elderly dialysis patients?

Time zone differences between patient and provider
Absence of lab result sharing
Digital literacy and comfort with video platforms (Correct answer)
Lack of insurance coverage for telehealth

Correct answer: Digital literacy and comfort with video platforms

Elderly patients often have lower digital literacy, making navigation of video platforms a significant barrier to telehealth participation.

Question 122: In an EHR-integrated nutrition care plan, which documentation element is most important for continuity when a renal dialysis patient transitions between an inpatient hospital and an outpatient dialysis unit?

A current, detailed renal diet prescription with recent lab-based nutrient targets and identified dietary barriers (Correct answer)
A list of the dietitian's credentials
The patient's insurance billing codes
The patient's social media accounts for contact

Correct answer: A current, detailed renal diet prescription with recent lab-based nutrient targets and identified dietary barriers

A current renal diet prescription with lab-based targets ensures the receiving care team can immediately continue appropriate dietary therapy without gaps.

Question 123: A renal nutrition QI team wants to prioritize which intervention to implement first. Using an impact-effort matrix, the team should FIRST address items that are:

Low impact and high effort
High impact and low effort (Correct answer)
High effort and high impact
Low effort and low impact

Correct answer: High impact and low effort

High-impact, low-effort interventions ('quick wins') are prioritized first because they yield the greatest benefit with the least resource investment.

Question 124: 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 (Correct answer)
Vitamin D toxicity causing hypercalcemia
Excessive oral caloric intake from dietary recall errors
Protein overconsumption leading to fluid retention

Correct answer: Glucose absorption from peritoneal dialysate

PD patients absorb significant glucose from dialysate, which can lead to hypertriglyceridemia, obesity, and metabolic complications that must be assessed and mitigated.

Question 125: A PD patient's peritoneal equilibration test (PET) reveals high transport status. What nutritional implication should the renal dietitian consider?

High transport status has no nutritional implications
High transporters need increased calcium supplementation
High transporters absorb more glucose from dialysate, increasing risk for obesity, hypertriglyceridemia, and malnutrition due to faster protein losses (Correct answer)
High transporters have better glucose absorption, requiring increased carbohydrate intake

Correct answer: High transporters absorb more glucose from dialysate, increasing risk for obesity, hypertriglyceridemia, and malnutrition due to faster protein losses

High transporters absorb more glucose from dialysate dextrose, increasing caloric load and cardiovascular risk, while also losing more protein into the dialysate.
