Time Allowed: 4 Hours
Total Questions: Approximately 200
Instructions:
Carefully read each question and select the most appropriate answer. Each
question has one correct answer unless otherwise stated. Manage your time
efficiently to ensure completion of all questions. Clinical judgment, evidence-
based practice, and application of nutrition support principles are required.
Calculators may be used where necessary. No external materials are
permitted.
Disclaimer:
This is an original simulated examination designed for educational purposes. It
is not affiliated with or endorsed as an official CNSC certification exam but
reflects the structure and competency domains typically assessed.
Core Competency Areas:
• Nutrition Assessment and Diagnosis
• Enteral and Parenteral Nutrition Support
• Metabolic and Physiologic Responses to Disease
• Pharmacology and Nutrient Interactions
• Monitoring and Evaluation of Nutrition Therapy
• Clinical Decision-Making in Specialized Populations
, This assessment evaluates advanced knowledge and clinical application in
nutrition support therapy. Candidates are expected to demonstrate
competency in managing complex patient scenarios involving enteral and
parenteral nutrition, including formulation, monitoring, and complication
management. Emphasis is placed on interdisciplinary care, critical thinking,
and adherence to evidence-based guidelines to optimize patient outcomes in
diverse clinical settings.
Q1. A critically ill patient with sepsis develops hyperglycemia despite no prior
history of diabetes. What is the primary mechanism responsible for this
metabolic change?
A. Increased insulin sensitivity
B. Decreased hepatic gluconeogenesis
C. Stress-induced insulin resistance
D. Increased peripheral glucose uptake
Correct Answer: C. Stress-induced insulin resistance
Explanation: Critical illness triggers a stress response involving
catecholamines, cortisol, and inflammatory cytokines, which induce insulin
resistance and increase hepatic glucose production. Option A is incorrect as
insulin sensitivity decreases. Option B is incorrect because gluconeogenesis
increases. Option D is incorrect since peripheral uptake is impaired.
Q2. A patient receiving enteral nutrition develops diarrhea. Which intervention
is most appropriate as an initial step?
A. Discontinue enteral feeding permanently
B. Add fiber-containing formula
C. Initiate parenteral nutrition
D. Increase feeding rate
,Correct Answer: B. Add fiber-containing formula
Explanation: Fiber can help normalize bowel function and improve
diarrhea. Option A is inappropriate as EN should not be stopped without cause.
Option C is unnecessary unless EN fails. Option D may worsen symptoms.
Q3. Which electrolyte abnormality is most associated with refeeding syndrome?
A. Hyperkalemia
B. Hyperphosphatemia
C. Hypophosphatemia
D. Hypernatremia
Correct Answer: C. Hypophosphatemia
Explanation: Refeeding syndrome causes intracellular shifts of phosphate
due to insulin release, leading to hypophosphatemia. Other options are
incorrect as they do not reflect this hallmark feature.
Q4. What is the recommended protein requirement for a critically ill patient
with normal renal function?
A. 0.6 g/kg/day
B. 0.8 g/kg/day
C. 1.2–2.0 g/kg/day
D. 3.0 g/kg/day
Correct Answer: C. 1.2–2.0 g/kg/day
Explanation: Critically ill patients require higher protein intake to preserve
, lean body mass. Options A and B are insufficient; D is excessive and may lead
to complications.
Q5. A patient on TPN develops elevated liver enzymes. What is the most likely
cause?
A. Protein deficiency
B. Excess carbohydrate intake
C. Electrolyte imbalance
D. Fluid overload
Correct Answer: B. Excess carbohydrate intake
Explanation: Excess dextrose can lead to hepatic steatosis and elevated liver
enzymes. Other options are less directly associated.
Q6. Which method best confirms feeding tube placement?
A. Auscultation
B. pH testing
C. Radiographic confirmation
D. Visual inspection
Correct Answer: C. Radiographic confirmation
Explanation: X-ray is the gold standard for confirming tube placement.
Other methods are unreliable.
