Question 1 of 20 Medium

What explains the rapid weight loss and muscle wasting in a burn client with a 40% TBSA burn?

  1. A A decreased metabolic rate that promotes catabolism
  2. B A hypermetabolic, hypercatabolic stress response
  3. C Increased fat storage with reduced protein breakdown
  4. D A normal, self-limiting post-burn metabolic response

Correct answer: A hypermetabolic, hypercatabolic stress response

Severe burn injury triggers a persistent hypermetabolic and hypercatabolic state with increased proteolysis, lipolysis and energy expenditure, causing muscle wasting and weight loss.

Question 2 of 20 Easy

What is the approximate protein requirement anticipated for a severely burned adult to support wound healing?

  1. A 0.8 g/kg/day
  2. B 1.0 g/kg/day
  3. C 1.5–2.0 g/kg/day
  4. D 3.0–4.0 g/kg/day

Correct answer: 1.5–2.0 g/kg/day

Adults with major burn injuries require significantly higher protein intake (about 1.5–2.0 g/kg/day) to support wound healing and counteract the catabolic state.

Question 3 of 20 Medium

Why is early enteral nutrition important for burn clients within 24-48 hours post-injury?

  1. A It is generally cheaper than parenteral nutrition
  2. B It reduces infection rates and length of stay
  3. C It permits continued fasting through surgeries
  4. D It ensures complete metabolic recovery in all clients

Correct answer: It reduces infection rates and length of stay

Early enteral feeding helps blunt the hypermetabolic response, maintain gut integrity and reduce infection and ICU stay in burn clients.

Question 4 of 20 Medium

Which macronutrient composition is preferred in the acute phase of burn recovery?

  1. A High fat (>40% non-protein calories), low carbohydrate
  2. B High carbohydrate, fat restricted (<30% non-protein calories)
  3. C Protein and fat only, with no carbohydrate provided
  4. D Equal carbohydrate and fat regardless of injury phase

Correct answer: High carbohydrate, fat restricted (<30% non-protein calories)

Burn patients benefit from a diet high in carbohydrates to spare protein, with fat restricted (generally <30% of non-protein calories) to avoid impairing immune function.

Question 5 of 20 Hard

Why is indirect calorimetry preferred over standard equations in measuring resting energy expenditure in burn patients?

  1. A Standard equations tend to overestimate caloric needs
  2. B Standard equations often underestimate true burn needs
  3. C It is a substantially cheaper bedside method
  4. D Burn patients maintain a normal resting energy expenditure

Correct answer: Standard equations often underestimate true burn needs

Standard predictive equations underestimate caloric needs in burn patients; indirect calorimetry better reflects the hypermetabolic state to tailor nutrient delivery.

Question 6 of 20 Easy

Which micronutrient is especially key for collagen synthesis and wound healing in burn patients?

  1. A Zinc
  2. B Vitamin C
  3. C Magnesium
  4. D Vitamin K

Correct answer: Vitamin C

Vitamin C is critical for collagen cross-linking and wound healing; burn patients often require higher intakes than normal.

Question 7 of 20 Medium

What is the correct statement about fat intake in the nutritional management of a burn client?

  1. A Fat should provide the majority (>50%) of total calories
  2. B Fat may be eliminated entirely during the acute phase
  3. C Fat should be limited (<30% non-protein calories) to protect immune function
  4. D Fat intake has no meaningful effect in burn nutrition

Correct answer: Fat should be limited (<30% non-protein calories) to protect immune function

Excessive fat in the acute burn phase can impair immune and healing responses; limiting fat is preferred using appropriate lipid sources.

Question 8 of 20 Hard

Why is a non-protein calorie to nitrogen ratio (NPC:N) of 150:1 significant in a burn client?

  1. A It signals that protein intake is excessive
  2. B It reflects an appropriate calorie-to-nitrogen balance for smaller burns
  3. C It has no real relevance in burn nutrition
  4. D It ensures a positive nitrogen balance in all clients

Correct answer: It reflects an appropriate calorie-to-nitrogen balance for smaller burns

NPC:N ratio helps assess adequate protein/energy balance; in smaller burns a ratio of 150:1 may be acceptable.

Question 9 of 20 Medium

Which statement best addresses fluid needs and hydration in burn nutrition support?

  1. A Fluid needs match those of non-burn patients
  2. B Fluid needs are lower because of tissue edema
  3. C Increased fluid and electrolytes are needed for exudate and hypermetabolic losses
  4. D Restricting fluids actively promotes wound healing

Correct answer: Increased fluid and electrolytes are needed for exudate and hypermetabolic losses

Burn patients often need increased fluid and electrolytes due to losses from wound exudate and hypermetabolism to support circulation and nutrition.

Question 10 of 20 Hard

What will further increase metabolic demands in a burn client with a 25% TBSA burn scheduled for multiple surgeries?

  1. A Repeated wound closure and grafting procedures
  2. B Limited mobility without other stressors
  3. C Deep sedation that eliminates all activity
  4. D The continued absence of any infection

Correct answer: Repeated wound closure and grafting procedures

Surgical interventions and wound closure procedures increase metabolic demands further due to increased tissue repair and stress, thus raising nutritional needs.

Question 11 of 20 Easy

What is the correct adult guideline for protein intake in major burns according to ESPEN/Burn guidelines?

  1. A 0.8 g/kg/day
  2. B 1.0 g/kg/day
  3. C 1.5–2.0 g/kg/day
  4. D 2.5–3.0 g/kg/day

Correct answer: 1.5–2.0 g/kg/day

Guideline recommendations indicate that severely burned adult patients should receive approximately 1.5–2.0 g/kg/day of protein to support healing.

Question 12 of 20 Medium

What risk does placing a burn client's nutritional support on hold frequently for test-fasting and surgery preps impose?

  1. A It tends to improve overall metabolic outcomes
  2. B It worsens negative nitrogen balance and delays healing
  3. C It has no measurable effect on nutritional status
  4. D It promotes beneficial fat accumulation for energy

Correct answer: It worsens negative nitrogen balance and delays healing

Interruptions in nutrient provision in hypermetabolic burn patients enhance muscle breakdown, increase negative nitrogen balance and delay healing.

Question 13 of 20 Medium

What is the most accurate statement about enteral versus parenteral nutrition in educating a burn client?

  1. A Parenteral nutrition is the preferred first route in burns
  2. B Enteral nutrition should be started early when feasible
  3. C Enteral nutrition is generally contraindicated in burns
  4. D The route of nutrition makes little clinical difference

Correct answer: Enteral nutrition should be started early when feasible

Early enteral nutrition is recommended in burn clients because it supports gut integrity, reduces infection and is preferred over parenteral when feasible.

Question 14 of 20 Medium

Why might a burn patient continue to lose lean body mass despite meeting calorie goals?

  1. A The prescribed calorie goals are set too high
  2. B Protein intake is inadequate or hypermetabolism persists
  3. C The patient is receiving excessive carbohydrate calories
  4. D Lean body mass loss is unrelated to nutritional intake

Correct answer: Protein intake is inadequate or hypermetabolism persists

Despite adequate calories, if protein is insufficient or the hypermetabolic state is unmanaged, lean body mass loss continues; high protein plus metabolic modulation are needed.

Question 15 of 20 Hard

What is the role of omega-3 fatty acids in burn nutrition support?

  1. A They raise proinflammatory cytokine production
  2. B They suppress and impair the immune response
  3. C They may improve immunity and reduce hyperglycemia by displacing omega-6 fats
  4. D They have no relevant role in burn nutrition

Correct answer: They may improve immunity and reduce hyperglycemia by displacing omega-6 fats

Diets richer in omega-3 fatty acids are associated with improved immune function and reduced hyperglycemia in burn patients.

Question 16 of 20 Hard

What is a unique nutritional concern in pediatric burn patients compared to adults?

  1. A A metabolic rate that is lower than expected
  2. B An absence of significant muscle catabolism
  3. C Prolonged hypermetabolism that can impair growth and development
  4. D A protein requirement lower than that of adults

Correct answer: Prolonged hypermetabolism that can impair growth and development

Children with severe burns experience prolonged hypermetabolism which can affect growth and development, making nutritional support especially important.

Question 17 of 20 Hard

What is a limitation in using the Curreri formula to estimate caloric needs in a burn patient?

  1. A It consistently overestimates caloric needs by about 50%
  2. B It is as accurate as indirect calorimetry
  3. C It often underestimates needs and ignores individual hypermetabolic variation
  4. D It applies only to pediatric burn patients

Correct answer: It often underestimates needs and ignores individual hypermetabolic variation

Predictive equations often fail to capture the heightened metabolic demands in burn patients accurately; indirect calorimetry remains the gold standard.

Question 18 of 20 Medium

What is an appropriate nutrition goal in the early care of burn patients?

  1. A Maintaining a negative nitrogen balance to save energy
  2. B Establishing positive nitrogen balance and meeting energy needs
  3. C Permitting a 3-5 day fast to lower metabolic demand
  4. D Replacing fluids alone while deferring nutrition

Correct answer: Establishing positive nitrogen balance and meeting energy needs

Early nutrition goals are to establish positive nitrogen balance and meet energy needs to promote wound healing and minimize lean body mass loss.

Question 19 of 20 Medium

What nutritional concern remains important when discharging a burn client from inpatient care to home?

  1. A Nutritional support is no longer required after discharge
  2. B Hypermetabolism may persist for months, so ongoing high protein, calories, and micronutrients matter
  3. C Only fluid restriction is relevant once the client is home
  4. D Nutrition no longer influences wound healing after discharge

Correct answer: Hypermetabolism may persist for months, so ongoing high protein, calories, and micronutrients matter

The hypermetabolic response to burns can persist long after the acute phase, so continuing nutritional support is important post-discharge.

Question 20 of 20 Hard

Which micronutrient deficiency is commonly seen in burn patients and must be monitored?

  1. A Isolated iron deficiency from blood loss
  2. B Deficiency of vitamin D, zinc, and selenium from increased losses
  3. C Isolated vitamin B12 deficiency from malabsorption
  4. D Isolated vitamin K deficiency affecting clotting

Correct answer: Deficiency of vitamin D, zinc, and selenium from increased losses

Burn patients often show deficiencies in micronutrients like vitamin D, zinc and selenium, crucial for wound healing and immune function.
