Certified Burn Registered Nurse (CBRN) Exam — Questions and Answers

Question 1: What is a burn contracture, and which anatomical areas are most commonly affected?

Fluid accumulation; the chest
Scar tissue limiting joint movement; neck and axilla are common sites (Correct answer)
Excessive granulation; the back
Infected wound tissue; the feet

Correct answer: Scar tissue limiting joint movement; neck and axilla are common sites

A burn contracture is scar tissue that restricts joint movement; the neck and axilla are frequently affected because scars cross flexion points and pull.

Question 2: A burn patient's family member asks, 'Should we avoid talking about the accident at home?' What is the nurse's best guidance?

Limit discussion to factual details and avoid emotional topics
Only discuss it during formal therapy sessions
Yes, discussing the accident increases PTSD risk
No, open communication at the family's pace supports emotional processing (Correct answer)

Correct answer: No, open communication at the family's pace supports emotional processing

Open, supportive communication at a pace comfortable for the survivor facilitates healthy emotional processing and reduces isolation.

Question 3: Which condition commonly necessitates post-pyloric (nasojejunal) feeding tube placement in burn patients?

Opioid-induced gastroparesis or critical illness-related ileus (Correct answer)
Hypervolemia
Hyperthermia
Hypertension

Correct answer: Opioid-induced gastroparesis or critical illness-related ileus

Opioid-induced gastroparesis and ileus impair gastric emptying, requiring post-pyloric tube placement to continue enteral nutrition delivery.

Question 4: What is the first step in managing a dry chemical (e.g., dry lime) burn to the skin?

Apply a neutralizing acid
Immediately immerse in a water bath
Brush off the powder before irrigating with copious water (Correct answer)
Cover with silver sulfadiazine

Correct answer: Brush off the powder before irrigating with copious water

Brushing off dry powder first prevents activating more chemical before prolonged irrigation.

Question 5: A nurse charting on a paper burn flowsheet makes an error. What is the correct correction method?

Use correction fluid and rewrite
Draw a single line through it, write "error," initial, date, and enter the correct information (Correct answer)
Black out the entry completely
Tear out the page and recopy the flowsheet

Correct answer: Draw a single line through it, write "error," initial, date, and enter the correct information

A single line keeps the original entry legible, preserving the legal integrity of the record.

Question 6: A burn patient's SpO2 reads 98% but the patient appears cyanotic with a suspected inhalation injury. What explains this discrepancy?

The reading reflects venous oxygen saturation
The patient has polycythemia
Pulse oximetry cannot distinguish carboxyhemoglobin from oxyhemoglobin (Correct answer)
Equipment malfunction

Correct answer: Pulse oximetry cannot distinguish carboxyhemoglobin from oxyhemoglobin

Standard pulse oximetry reads carboxyhemoglobin as oxyhemoglobin, giving falsely normal readings in carbon monoxide poisoning; co-oximetry or ABG is required.

Question 7: Which nutritional marker is more responsive than albumin for monitoring short-term nutritional status in burn patients?

Total lymphocyte count
Serum albumin
Body weight
Prealbumin (transthyretin) (Correct answer)

Correct answer: Prealbumin (transthyretin)

Prealbumin has a 2–3 day half-life, making it more responsive than albumin for tracking short-term changes in nutritional status.

Question 8: A full-thickness burn wound appears pale and leathery with no blistering. What best explains the absence of pain in this wound?

Vasodilation blocking pain signals
Adequate analgesia administration
Superficial dermal involvement only
Destruction of nerve endings in the dermis (Correct answer)

Correct answer: Destruction of nerve endings in the dermis

Full-thickness burns destroy nerve endings, causing insensitivity to pain in the wound itself.

Question 9: A patient with a major burn starts oxandrolone 10 mg PO twice daily. Which lab value should the nurse monitor most closely?

Serum amylase
Thyroid-stimulating hormone
Serum magnesium
Liver function tests (Correct answer)

Correct answer: Liver function tests

Oxandrolone is an anabolic steroid that can cause hepatotoxicity, so transaminases are monitored regularly.

Question 10: A malnourished burn patient starts aggressive nutrition support. Which electrolyte abnormality is the classic sign of refeeding syndrome?

Hypercalcemia
Hypernatremia
Hypophosphatemia (Correct answer)
Hyperkalemia

Correct answer: Hypophosphatemia

Insulin released with refeeding shifts phosphate into cells, which causes a dangerous drop in serum phosphate.

Question 11: Which of the following methods is best for monitoring fluid resuscitation success?

Blood sugar levels.
Urine output greater than 0.5 mL/kg/hr (Correct answer)
Heart rate only.
Capillary refill time.

Correct answer: Urine output greater than 0.5 mL/kg/hr

Monitoring urine output is the most reliable and direct method for assessing the adequacy of fluid resuscitation in burn patients. A urine output greater than 0.5 mL/kg/hr (for adults) indicates that the kidneys are adequately perfused and functioning well, signifying sufficient circulating blood volume. While other parameters like heart rate are important, urine output provides a direct measure of end-organ perfusion.

Question 12: What role do antibiotics play in infection prevention for burn patients?

They are used for all patients regardless of condition.
They are used as prophylaxis for all wounds.
They replace the need for wound care.
They are prescribed when clinical signs of infection are present (Correct answer)

Correct answer: They are prescribed when clinical signs of infection are present

In burn care, antibiotics are generally not used prophylactically for all burn wounds due to the risk of promoting antibiotic resistance and fungal overgrowth. Instead, they are prescribed specifically when clinical signs of infection are present, such as fever, increased wound exudate, purulence, or positive wound cultures. This targeted approach ensures appropriate use and effectiveness of antibiotics while minimizing adverse effects.

Question 13: In Certified Burn Registered Nurse practice, what is the FIRST step when a safety hazard is identified in the workplace?

Continue working and report at end of shift
Document it for the next safety audit
Immediately secure the area and report the hazard (Correct answer)
Wait for a supervisor to notice the issue

Correct answer: Immediately secure the area and report the hazard

When a safety hazard is identified, the immediate priority is to secure the area to prevent injury and report the hazard through proper channels. Delaying action increases the risk of incidents.

Question 14: Which opioid analgesic is most appropriate for procedural pain (e.g., dressing changes) in burn patients due to its rapid onset and short duration of action?

Fentanyl (Correct answer)
Hydromorphone
Methadone
Codeine

Correct answer: Fentanyl

Fentanyl is ideal for procedural pain in burn patients due to its rapid IV onset (1-2 minutes), short duration of action, and high potency, making it effective for painful dressing changes.

Question 15: A nurse observes that a burn patient's urine output has decreased to 0.3 mL/kg/hr. What does this most likely indicate?

Normal diuretic phase response
Adequate fluid resuscitation
Hypervolemia
Impending acute kidney injury (Correct answer)

Correct answer: Impending acute kidney injury

Urine output below 0.5 mL/kg/hr in a burn patient signals inadequate perfusion and risk of acute kidney injury requiring prompt intervention.

Question 16: In a ventilated burn patient, which bundle element is most critical for preventing ventilator-associated pneumonia (VAP)?

Daily sedation vacation and elevation of head of bed to 30–45° (Correct answer)
Keeping the cuff pressure below 15 cmH2O
Continuous nebulized antibiotics
Routine bronchoscopy every 48 hours

Correct answer: Daily sedation vacation and elevation of head of bed to 30–45°

Daily sedation interruption combined with semi-recumbent positioning (30–45°) are core VAP bundle elements proven to reduce pneumonia incidence.

Question 17: N-acetylcysteine (NAC) is used in burn patients with inhalation injury primarily because it acts as:

A hepatoprotectant against antibiotic-induced liver toxicity
An opioid antagonist to reverse respiratory depression
A mucolytic and antioxidant to reduce airway secretion burden and oxidative damage (Correct answer)
An antibiotic to prevent secondary pneumonia

Correct answer: A mucolytic and antioxidant to reduce airway secretion burden and oxidative damage

N-acetylcysteine serves as both a mucolytic (breaks down thick airway secretions) and an antioxidant (scavenges free radicals), helping manage the airway and reduce oxidative damage from inhalation injury.

Question 18: Which anticoagulation strategy is most commonly used in burn patients for deep vein thrombosis (DVT) prophylaxis?

Warfarin with daily INR monitoring
Direct oral anticoagulants like rivaroxaban
Aspirin 325 mg daily alone
Low molecular weight heparin (LMWH) such as enoxaparin (Correct answer)

Correct answer: Low molecular weight heparin (LMWH) such as enoxaparin

Low molecular weight heparin (e.g., enoxaparin) is the preferred DVT prophylaxis in burn patients due to predictable pharmacokinetics, no need for frequent monitoring, and effectiveness in the hypercoagulable post-burn state.

Question 19: Which factor MOST significantly affects the quality of technical outcomes in CBRN practice?

The speed at which procedures are completed
The brand of equipment being used
The time of day the procedure is performed
The practitioner's training, preparation, and attention to detail (Correct answer)

Correct answer: The practitioner's training, preparation, and attention to detail

The quality of technical outcomes depends primarily on the practitioner's level of training, thorough preparation, and careful attention to detail. While equipment matters, the professional's competence is the most significant factor.

Question 20: Which micronutrient is commonly supplemented in burn patients to support collagen synthesis and immune function?

Vitamin K
Vitamin C (Correct answer)
Vitamin B12
Vitamin D

Correct answer: Vitamin C

Vitamin C supports collagen synthesis, antioxidant defense, and immune function — all critical for wound healing in burn patients.

Question 21: When administering systemic antibiotics to burn patients, the burn nurse should anticipate that dosing requirements will typically differ from standard dosing because:

Oral antibiotics are preferred to avoid IV line-associated infections
Standard doses require no adjustment in burn patients
Higher doses and/or more frequent dosing are needed due to increased volume of distribution and augmented renal clearance (Correct answer)
Lower doses are needed due to impaired renal clearance from burn-related AKI

Correct answer: Higher doses and/or more frequent dosing are needed due to increased volume of distribution and augmented renal clearance

Altered pharmacokinetics in burn patients — including increased volume of distribution, hypermetabolism, and augmented renal clearance — frequently require higher doses or more frequent antibiotic administration to achieve therapeutic levels.

Question 22: Burn patients who receive prolonged silver nitrate 0.5% dressing treatment are at risk for which electrolyte complication?

Hypercalcemia and hypermagnesemia
Hyponatremia and hypochloremia (Correct answer)
Hyperchloremia and hypernatremia
Hyperkalemia and metabolic acidosis

Correct answer: Hyponatremia and hypochloremia

Silver nitrate leaches sodium and chloride from the wound, causing hyponatremia and hypochloremia that requires close electrolyte monitoring.

Question 23: What is the significance of monitoring white blood cell (WBC) counts in burn patients?

It helps assess infection or sepsis risk (Correct answer)
It measures renal function.
It indicates hydration status.
WBC count has no relevance.

Correct answer: It helps assess infection or sepsis risk

White blood cell (WBC) counts are a crucial indicator in burn patients because an elevated count (leukocytosis) or a significantly depressed count (leukopenia) can signal the presence of infection or sepsis. Burn injuries cause a systemic inflammatory response, and changes in WBC count help clinicians identify and monitor the body's response to potential pathogens. This monitoring aids in early detection and management of infectious complications.

Question 24: Ketamine is chosen for procedural sedation during a pediatric burn dressing change. Which nursing intervention best addresses a common adverse effect of this drug?

Provide a calm, low-stimulus recovery environment and consider a benzodiazepine (Correct answer)
Hold all oral intake for 24 hours after the procedure
Administer naloxone immediately after the dressing change
Place the patient flat and restrict fluids to prevent hypertension

Correct answer: Provide a calm, low-stimulus recovery environment and consider a benzodiazepine

Ketamine can cause emergence reactions such as hallucinations and agitation, which are reduced by a quiet environment and benzodiazepine premedication.

Question 25: Which electrolyte abnormality is most frequently monitored in burn patients receiving silver nitrate soaks?

Hypercalcemia
Hypochloremia and hyponatremia (Correct answer)
Hypernatremia
Hyperkalemia

Correct answer: Hypochloremia and hyponatremia

Silver nitrate is hypotonic and leaches sodium and chloride from wounds, requiring frequent monitoring and replacement of these electrolytes.

Question 26: What is the main metabolic benefit of giving propranolol to a patient with a severe burn?

It increases insulin resistance to keep glucose available
It stimulates appetite to improve oral intake
It reduces catecholamine-driven hypermetabolism and muscle protein breakdown (Correct answer)
It raises resting energy expenditure to speed wound healing

Correct answer: It reduces catecholamine-driven hypermetabolism and muscle protein breakdown

Beta-blockade lowers heart rate, resting energy expenditure, and skeletal muscle catabolism after a burn.

Question 27: Which type of scar is raised, reddened, and confined to the original wound boundaries in a burn patient?

Contracture band
Hypertrophic scar (Correct answer)
Atrophic scar
Keloid scar

Correct answer: Hypertrophic scar

Hypertrophic scars are raised, erythematous, and remain within the wound margins, unlike keloids which extend beyond the original injury boundaries.

Question 28: A patient recovering from a major burn is started on oxandrolone to promote lean body mass and wound healing. Which laboratory value is most important to monitor?

Thyroid-stimulating hormone
Liver function tests (Correct answer)
Serum lithium level
Serum amylase

Correct answer: Liver function tests

Oxandrolone is an anabolic steroid that can cause hepatotoxicity, so transaminases must be monitored routinely.

Question 29: A worker arrives with a dry lime (calcium oxide) powder burn. What is the nurse's priority first step?

Immediately flush with water
Brush off the dry powder before irrigation (Correct answer)
Cover with a dry sterile dressing
Apply a neutralizing acid

Correct answer: Brush off the dry powder before irrigation

Dry chemical powders should be brushed off first because water can activate them and cause more injury, then copious irrigation follows.

Question 30: An elderly burn patient's injuries do not match the caregiver's story, and the patient appears fearful. What is the nurse's legal obligation?

Confront the caregiver before charting
Wait for the physician to decide if reporting is needed
Document only the patient's subjective statements
Report suspected elder abuse to Adult Protective Services per state law and document objective findings (Correct answer)

Correct answer: Report suspected elder abuse to Adult Protective Services per state law and document objective findings

Nurses are mandated reporters of suspected elder abuse and must document objective, factual findings.

Question 31: What room temperature is generally recommended for a patient with major burns during dressing changes?

Around 85°F (29-32°C) (Correct answer)
70-72°F (21-22°C)
64-68°F (18-20°C)
Over 100°F (38°C)

Correct answer: Around 85°F (29-32°C)

Warm rooms near 85°F (about 30-32°C) reduce heat loss and the hypermetabolic burden in patients who have lost skin's thermoregulatory barrier.

Question 32: Using the Curreri formula (25 kcal/kg + 40 kcal/%TBSA), what is the estimated daily caloric need for a 70-kg adult with a 40% TBSA burn?

2,850 kcal/day
3,750 kcal/day
4,150 kcal/day
3,350 kcal/day (Correct answer)

Correct answer: 3,350 kcal/day

(25 × 70) + (40 × 40) = 1,750 + 1,600 = 3,350 kcal/day.

Question 33: A burn patient's arterial blood gas shows pH 7.30, PaCO2 28 mmHg, HCO3 13 mEq/L. How should this be interpreted?

Metabolic acidosis with respiratory compensation (Correct answer)
Mixed respiratory and metabolic alkalosis
Uncompensated respiratory acidosis
Respiratory alkalosis with metabolic compensation

Correct answer: Metabolic acidosis with respiratory compensation

The low pH with low bicarbonate indicates a primary metabolic acidosis; the low PaCO2 reflects appropriate respiratory compensation (hyperventilation).

Question 34: What is the PRIMARY reason for regulatory compliance in the Certified Burn Registered Nurse profession?

To protect public safety, ensure quality standards, and maintain professional integrity (Correct answer)
To justify higher service fees
To avoid penalties and fines only
To create additional paperwork for documentation

Correct answer: To protect public safety, ensure quality standards, and maintain professional integrity

Regulatory compliance serves the broader purpose of protecting public safety, ensuring consistent quality standards, and maintaining the integrity of the profession. While avoiding penalties is a benefit, the primary motivation is safeguarding the public interest.

Question 35: Which of the following is a key sign of sepsis in burn patients?

Elevated temperature with tachycardia and hypotension (Correct answer)
Normal blood pressure
Bradycardia
Localized redness

Correct answer: Elevated temperature with tachycardia and hypotension

Sepsis in burn patients is a severe systemic inflammatory response to infection, often characterized by a cluster of signs including elevated temperature (fever), tachycardia (increased heart rate), and hypotension (low blood pressure). These vital sign changes indicate a widespread physiological compromise and require immediate medical intervention. Localized redness alone is not indicative of systemic sepsis.

Question 36: Which psychological condition is commonly encountered in burn survivors during the rehabilitation phase?

Bipolar disorder
Schizophrenia
Post-traumatic stress disorder (PTSD) (Correct answer)
Parkinson's disease

Correct answer: Post-traumatic stress disorder (PTSD)

PTSD is common in burn survivors due to the traumatic injury, painful procedures, and altered body image, requiring integrated psychological support throughout rehabilitation.

Question 37: Which laboratory finding is most consistent with early disseminated intravascular coagulation (DIC) in a burn patient?

Prolonged PT/PTT, decreased fibrinogen, and thrombocytopenia (Correct answer)
Elevated fibrinogen and platelet count
Isolated thrombocytosis with normal coagulation
Elevated D-dimer with normal PT/PTT

Correct answer: Prolonged PT/PTT, decreased fibrinogen, and thrombocytopenia

DIC is characterized by consumption of clotting factors and platelets, resulting in prolonged PT/PTT, decreased fibrinogen, and low platelet counts.

Question 38: Which splint position is recommended for patients with dorsal hand burns to prevent intrinsic-minus deformity?

Full fist position
Neutral wrist, full finger extension
Wrist flexion, MCP flexion, IP extension
Wrist extension, MCP flexion at 70–90°, IP extension, thumb abduction (Correct answer)

Correct answer: Wrist extension, MCP flexion at 70–90°, IP extension, thumb abduction

The intrinsic-plus (safe) position — wrist extension, MCP flexion at 70–90°, IP extension, thumb abduction — prevents deformity and maintains intrinsic muscle length.

Question 39: Which finding most strongly supports the need for fasciotomy in a patient with a high-voltage electrical injury to the forearm?

Pain controlled with opioids
Compartment pressure above 30 mmHg (Correct answer)
Capillary refill of 2 seconds
Mild edema of the fingers

Correct answer: Compartment pressure above 30 mmHg

A measured compartment pressure over 30 mmHg (or delta pressure under 30) indicates compartment syndrome requiring fasciotomy.

Question 40: Which factor most increases a burn patient's risk for developing a catheter-associated urinary tract infection (CAUTI)?

High fluid intake
Prolonged indwelling urinary catheter use (Correct answer)
Hyperglycemia alone
Frequent dressing changes

Correct answer: Prolonged indwelling urinary catheter use

Duration of catheterization is the strongest modifiable risk factor for CAUTI; daily reassessment and early removal are key prevention strategies.

Question 41: A typical split-thickness skin graft donor site re-epithelializes within approximately how long?

10–14 days (Correct answer)
2–3 months
3–5 days
4–6 weeks

Correct answer: 10–14 days

Donor sites heal from retained adnexal structures, usually within 10–14 days.

Question 42: What is the primary physiological response to a severe burn injury?

Hypervolemia and low inflammation
Hypovolemia and capillary leakage (Correct answer)
Vasoconstriction and low output
Minimal physiological change

Correct answer: Hypovolemia and capillary leakage

A severe burn injury causes a massive fluid shift from the intravascular space into the interstitial space due to increased capillary permeability. This leads to significant hypovolemia, or a decrease in circulating blood volume, and is a critical initial physiological response known as burn shock. Immediate fluid resuscitation is necessary to counteract this life-threatening condition.

Question 43: What is a key principle in managing pain during wound care procedures?

Avoid analgesics to reduce sedation risk.
Administer analgesia after procedures.
Use distraction techniques only.
Provide analgesics prior to wound care (Correct answer)

Correct answer: Provide analgesics prior to wound care

Pain management is crucial in burn care, especially during wound care procedures which can be extremely painful. Administering analgesics prior to wound care ensures that the medication has time to take effect, reducing the patient's pain and anxiety during the procedure. This proactive approach improves patient comfort, cooperation, and overall experience, facilitating better wound care.

Question 44: Which risk management approach is MOST effective for CBRN professionals when evaluating potential workplace hazards?

Relying solely on historical accident data
Delegating all safety decisions to management
Proactive hazard identification and assessment (Correct answer)
Reactive analysis after incidents occur

Correct answer: Proactive hazard identification and assessment

Proactive hazard identification and assessment allows professionals to identify and mitigate risks before incidents occur, which is far more effective than reactive approaches that only address problems after they happen.

Question 45: Which pain assessment tool is particularly useful for pediatric burn patients or those unable to verbalize pain scores?

Lund and Browder Chart
Abbreviated Burn Severity Index
FACES Pain Scale (Correct answer)
Vancouver Scar Scale

Correct answer: FACES Pain Scale

The FACES Pain Scale uses illustrated facial expressions to communicate pain intensity, making it especially effective for young children or non-verbal burn patients.

Question 46: When using a medical interpreter for burn discharge teaching with a limited-English-proficient patient, what should be documented?

Nothing, since interpretation is routine
That a family child interpreted to save time
The interpreter's name or ID number and that teach-back confirmed understanding (Correct answer)
Only that written English instructions were given

Correct answer: The interpreter's name or ID number and that teach-back confirmed understanding

Documenting the qualified interpreter and teach-back shows that understanding was confirmed, as required by Title VI language access rules.

Question 47: What is the primary benefit of hydrotherapy in burn rehabilitation?

Facilitates wound cleaning and range-of-motion exercises in a buoyant medium (Correct answer)
Replaces surgical debridement
Eliminates need for dressing changes
Prevents infection entirely

Correct answer: Facilitates wound cleaning and range-of-motion exercises in a buoyant medium

Hydrotherapy allows gentle wound cleaning and range-of-motion exercises in warm water where buoyancy reduces pain and resistance during movement.

Question 48: What surgical technique is commonly used to release a burn scar contracture that limits joint function?

Escharotomy
Contracture release with Z-plasty (Correct answer)
Debridement
Fasciotomy

Correct answer: Contracture release with Z-plasty

Contracture release using Z-plasty or other reconstructive techniques surgically corrects burn scar contractures that limit joint range of motion.

Question 49: A 15-year-old with a minor burn arrives without a parent and needs non-emergent debridement. Which is generally required before treatment?

Consent from the parent or legal guardian, unless the minor is emancipated or a state exception applies (Correct answer)
No consent is needed for minors
Consent from the minor alone in all cases
Verbal approval from a school teacher

Correct answer: Consent from the parent or legal guardian, unless the minor is emancipated or a state exception applies

Minors usually cannot consent to non-emergent care unless emancipated or covered by a specific state exception.

Question 50: Which antimicrobial agent is applied topically and is known to penetrate eschar most effectively?

Mafenide acetate (Correct answer)
Mupirocin
Bacitracin
Silver sulfadiazine

Correct answer: Mafenide acetate

Mafenide acetate (Sulfamylon) is the only topical agent that penetrates burn eschar, making it effective against deep infections.

Question 51: Which factor is MOST predictive of long-term psychosocial adjustment in adult burn survivors?

Length of hospital stay
Perceived social support from family and peers (Correct answer)
Number of surgical procedures required
Total body surface area (TBSA) burned

Correct answer: Perceived social support from family and peers

Research consistently shows that perceived social support is the strongest predictor of positive psychosocial outcomes, independent of injury severity.

Question 52: Which laboratory change should the nurse monitor for in the first days after starting silver sulfadiazine?

Transient leukopenia (Correct answer)
Metabolic alkalosis
Hyperkalemia
Thrombocytosis

Correct answer: Transient leukopenia

Silver sulfadiazine can cause a transient, usually self-limiting drop in white blood cell count.

Question 53: Which statement about methadone use in burn pain management is correct?

Methadone is useful for chronic burn pain due to its long half-life and NMDA antagonism (Correct answer)
Methadone has no drug-drug interactions relevant to burn care
Methadone is contraindicated in patients with inhalation injuries
Methadone has a short half-life making it safe for PRN dosing

Correct answer: Methadone is useful for chronic burn pain due to its long half-life and NMDA antagonism

Methadone's long half-life provides sustained analgesia and its NMDA receptor antagonism helps combat opioid tolerance, making it useful in chronic burn pain management.

Question 54: The hypermetabolic response following major burn injury peaks at approximately what time post-burn?

5-10 days (Correct answer)
Immediately at time of injury
12-24 hours
3-4 weeks

Correct answer: 5-10 days

The hypermetabolic response typically peaks around 5-10 days post-burn as inflammatory mediators drive a massive increase in metabolic rate.

Question 55: Which formula is commonly used to calculate fluid resuscitation needs in burn patients?

Henderson-Hasselbalch formula
Modified Duke formula
Parkland formula (Correct answer)
Clark's rule

Correct answer: Parkland formula

The Parkland formula is the most commonly used and widely accepted method for calculating fluid resuscitation needs in burn patients during the initial 24 hours post-injury. This formula helps clinicians determine the precise amount of intravenous fluids required to prevent hypovolemic shock and maintain adequate organ perfusion. It is a critical tool for guiding fluid management in severe burn cases.

Question 56: Indirect calorimetry on a burn patient shows a respiratory quotient (RQ) of 1.08. What does this most likely indicate?

Overfeeding with lipogenesis (Correct answer)
Underfeeding with ketosis
Ideal mixed substrate use
Predominant fat oxidation

Correct answer: Overfeeding with lipogenesis

An RQ above 1.0 suggests excess carbohydrate being converted to fat, which raises CO2 production.

Question 57: A burn patient on total parenteral nutrition (TPN) develops a fever and erythema around a central line site. What is the priority nursing intervention?

Slow the TPN infusion rate
Administer vancomycin through the existing line
Remove and culture the central line per protocol (Correct answer)
Apply topical antibiotic ointment to the site

Correct answer: Remove and culture the central line per protocol

Suspected catheter-related bloodstream infection requires removal of the central line and culture of the tip to guide antibiotic therapy.

Question 58: What is the purpose of critical care monitoring in burn patients?

To maintain cosmetic appearance.
To minimize hospital stay.
To monitor fluid balance, organ function, and vital signs (Correct answer)
To encourage ambulation.

Correct answer: To monitor fluid balance, organ function, and vital signs

Critical care monitoring in burn patients is essential for continuously assessing their physiological status due to the severe systemic effects of burn injuries. This involves closely tracking fluid balance, ensuring adequate organ perfusion and function, and monitoring vital signs for any signs of deterioration or complications like shock or sepsis. This comprehensive monitoring guides treatment decisions and optimizes patient outcomes.

Question 59: The current standard multimodal pain management approach for burn patients includes:

Combination of opioids, non-opioids (acetaminophen, NSAIDs), and adjuncts (ketamine, gabapentin) (Correct answer)
Opioids alone with escalating doses as tolerance develops
NSAIDs exclusively to avoid opioid-related side effects
Epidural analgesia as the primary and sole modality

Correct answer: Combination of opioids, non-opioids (acetaminophen, NSAIDs), and adjuncts (ketamine, gabapentin)

Multimodal analgesia combining opioids, non-opioids, and adjuvant agents provides superior pain control with fewer adverse effects than single-agent therapy in burn patients.

Question 60: How often should dressing changes occur in infected burn wounds?

Once per week.
Every 48–72 hours.
As frequently as prescribed based on infection severity (Correct answer)
Only when the dressing falls off.

Correct answer: As frequently as prescribed based on infection severity

The frequency of dressing changes for infected burn wounds is highly individualized and depends on the severity of the infection, the type of dressing, and the patient's overall condition. There is no fixed schedule; instead, changes are performed as often as necessary to manage exudate, apply topical antimicrobials, and assess the wound, as prescribed by the healthcare team. This ensures optimal wound healing and infection control.

Question 61: In a burn unit, which surface is considered the highest-risk vector for cross-contamination between patients?

Healthcare worker hands (Correct answer)
Patient bedding
Air vents in the room
IV tubing

Correct answer: Healthcare worker hands

Healthcare worker hands are the most common vehicle for pathogen transmission between patients, making hand hygiene the single most important infection control measure.

Question 62: What is the primary purpose of indirect calorimetry in burn patient care?

Measure respiratory rate
Calculate fluid balance
Determine actual resting energy expenditure (Correct answer)
Monitor cardiac output

Correct answer: Determine actual resting energy expenditure

Indirect calorimetry measures oxygen consumption and CO2 production to calculate actual resting energy expenditure, enabling precise caloric goals.

Question 63: Approximately how long does it take to grow cultured epidermal autografts from a patient's skin biopsy?

24–48 hours
3–5 days
3 months
2–3 weeks (Correct answer)

Correct answer: 2–3 weeks

Keratinocytes are cultured for roughly 2–3 weeks before sheets are ready for application.

Question 64: Which route of nutrition is preferred for burn patients when the gastrointestinal tract is functional?

Oral supplementation alone
Total parenteral nutrition
Enteral nutrition via nasogastric tube (Correct answer)
Peripheral IV glucose infusion

Correct answer: Enteral nutrition via nasogastric tube

Enteral nutrition is preferred in burn patients because it maintains gut integrity, reduces bacterial translocation, and carries fewer complications than parenteral nutrition.

Question 65: What is the primary reason burn nurses use strict sterile technique rather than clean technique during wound debridement?

Clean technique is reserved for chronic wounds only
Sterile technique accelerates healing by reducing inflammation
Burn wounds lack skin barrier, making them highly susceptible to exogenous contamination (Correct answer)
Sterile technique is hospital policy only

Correct answer: Burn wounds lack skin barrier, making them highly susceptible to exogenous contamination

Absence of the skin barrier in burn wounds creates a direct portal for microorganism entry, necessitating sterile technique to prevent infection.

Question 66: Which regulatory requirement is UNIVERSAL across all Certified Burn Registered Nurse practice settings?

Using specific proprietary software systems
Working exclusively during business hours
Limiting services to local jurisdictions only
Maintaining current certification and meeting continuing education requirements (Correct answer)

Correct answer: Maintaining current certification and meeting continuing education requirements

Maintaining current certification and meeting continuing education requirements is a universal regulatory requirement. Regardless of practice setting, professionals must keep their credentials current and demonstrate ongoing competency through continuing education.

Question 67: An enterally fed burn patient has a gastric residual volume of 300 mL, a soft abdomen, and no vomiting. What is the best nursing action?

Continue feeds and keep assessing for intolerance (Correct answer)
Stop feeds for 24 hours
Lower feeds to trophic rate permanently
Switch to parenteral nutrition

Correct answer: Continue feeds and keep assessing for intolerance

Feeds should not be held for a residual under 500 mL when there are no other signs of intolerance, because holding feeds causes underfeeding.

Question 68: Mafenide acetate (Sulfamylon) is preferred over silver sulfadiazine in which clinical situation?

Superficial partial-thickness burns on the torso
Burns with suspected deep infection requiring eschar penetration (Correct answer)
Facial burns near the eyes
Burns in neonates under 2 months

Correct answer: Burns with suspected deep infection requiring eschar penetration

Mafenide acetate penetrates eschar more effectively than silver sulfadiazine, making it the preferred agent when deep infection is suspected or confirmed.

Question 69: Which zone of Jackson's burn model contains irreversibly damaged, necrotic tissue at the burn center?

Zone of ischemia
Zone of stasis
Zone of hyperemia
Zone of coagulation (Correct answer)

Correct answer: Zone of coagulation

The zone of coagulation is the innermost, most damaged area where protein coagulation causes irreversible cell death.

Question 70: Which is a common psychosocial challenge faced by burn patients?

Improved social interaction.
Improved memory.
Decreased appetite only.
Depression and body image concerns (Correct answer)

Correct answer: Depression and body image concerns

Burn patients frequently face significant psychosocial challenges, with depression and body image concerns being among the most common. The physical disfigurement, pain, prolonged hospitalization, and functional limitations can lead to profound emotional distress, anxiety, and difficulties adjusting to changes in their appearance and lifestyle. Addressing these concerns is crucial for holistic recovery.

Question 71: A burn nurse notes the patient's urine output is 150 mL/hr. The most appropriate next action is to:

Administer a 500 mL fluid bolus
Decrease the fluid infusion rate (Correct answer)
Continue current fluid rate and reassess in 4 hours
Insert a second IV line and increase rate

Correct answer: Decrease the fluid infusion rate

Urine output >1 mL/kg/hr signals over-resuscitation; decreasing the infusion rate prevents fluid creep and associated complications like abdominal compartment syndrome.

Question 72: A burn nurse realizes 3 hours later that she forgot to chart an hourly urine output. What is the correct way to document it?

Omit it, since the time has passed
Write the value in the original time slot without notation
Enter a clearly labeled late entry with the current date/time, referencing the original time (Correct answer)
Ask a colleague to chart it under their login

Correct answer: Enter a clearly labeled late entry with the current date/time, referencing the original time

Late entries must be clearly identified as late, timestamped when written, and reference the time of the original event.

Question 73: A patient sustains a burn injury. Which mediator is primarily responsible for the early increase in capillary permeability?

Angiotensin II
Interleukin-6
Thromboxane A2
Histamine (Correct answer)

Correct answer: Histamine

Histamine released from mast cells causes the initial increase in capillary permeability within the first 30 minutes post-burn.

Question 74: What is the significance of a wound biopsy count exceeding 10^5 organisms per gram of tissue in a burn patient?

It is the threshold associated with invasive burn wound infection (Correct answer)
It indicates superficial colonization only
It predicts wound healing within 5 days
It requires immediate skin grafting

Correct answer: It is the threshold associated with invasive burn wound infection

A bacterial count >10^5 organisms per gram of tissue indicates invasive infection that can impede graft take and cause systemic sepsis.

Question 75: What does the term 'donor site' refer to in burn surgery and rehabilitation?

The area where the burn occurred
The intact skin surrounding the burn
The area receiving the skin graft
The area where split-thickness skin graft is harvested (Correct answer)

Correct answer: The area where split-thickness skin graft is harvested

A donor site is the intact skin area from which a split-thickness graft is harvested; donor sites require their own wound care and pain management during rehabilitation.

Question 76: How should Certified Burn Registered Nurse professionals handle technical procedures that have been updated or revised?

Only apply updates to new cases or projects
Continue using the original method if it still works
Wait for mandatory enforcement before changing
Review the updates, complete any required training, and implement the revised procedures (Correct answer)

Correct answer: Review the updates, complete any required training, and implement the revised procedures

When procedures are updated, professionals must review the changes, complete any required training to understand the rationale and new requirements, and implement the revised procedures in their practice. Continuing outdated methods risks non-compliance and suboptimal outcomes.

Question 77: Which regulatory requirement is UNIVERSAL across all Certified Burn Registered Nurse practice settings?

Using specific proprietary software systems
Maintaining current certification and meeting continuing education requirements (Correct answer)
Limiting services to local jurisdictions only
Working exclusively during business hours

Correct answer: Maintaining current certification and meeting continuing education requirements

Question 78: Which clinical sign best differentiates a superficial partial-thickness burn from a deep partial-thickness burn?

Wound size in cm²
Capillary refill time
Wound color (pink vs. pale/mottled) (Correct answer)
Presence of blisters

Correct answer: Wound color (pink vs. pale/mottled)

Superficial partial-thickness burns appear pink and moist, while deep partial-thickness burns are pale, mottled, or white due to greater dermal destruction.

Question 79: What is the recommended glycemic target range for critically ill burn patients per current evidence-based guidelines?

60–100 mg/dL
200–240 mg/dL
140–180 mg/dL (Correct answer)
80–110 mg/dL

Correct answer: 140–180 mg/dL

Guidelines recommend 140–180 mg/dL to balance the harms of hyperglycemia and hypoglycemia, avoiding tight control due to hypoglycemia risk.

Question 80: Why are burn patients at particularly high risk of infection compared with other trauma patients?

They have increased skin barrier function
Loss of skin barrier plus burn-induced immunosuppression (Correct answer)
They receive no invasive devices
Burn eschar is naturally antimicrobial

Correct answer: Loss of skin barrier plus burn-induced immunosuppression

Burns destroy the skin barrier and cause systemic immune dysfunction, while the avascular eschar supports bacterial growth.

Question 81: What is the primary goal of wound debridement in burn care?

Remove dead tissue and promote healing (Correct answer)
Prevent debridement
Reduce fluid loss
Promote scar formation

Correct answer: Remove dead tissue and promote healing

The primary goal of wound debridement in burn care is to remove dead, devitalized tissue (eschar) from the burn wound. Necrotic tissue provides a breeding ground for bacteria, increasing the risk of infection and impeding the natural healing process. By removing this tissue, debridement promotes a clean wound bed, reduces the bacterial load, and facilitates healthy granulation tissue formation and wound closure.

Question 82: What is the primary concern with total parenteral nutrition (TPN) in burn patients who cannot tolerate enteral feeding?

Increased infection risk and gut mucosal atrophy (Correct answer)
Hypoglycemia
Electrolyte stability
Excessive weight gain

Correct answer: Increased infection risk and gut mucosal atrophy

TPN bypasses the gut, leading to intestinal mucosal atrophy, bacterial translocation, and higher infection risk from central venous catheter use.

Question 83: In a burn patient with a 40% TBSA burn, how does severe protein catabolism typically manifest on laboratory evaluation?

Negative nitrogen balance (Correct answer)
Increased muscle mass
Decreased BUN
Elevated serum albumin

Correct answer: Negative nitrogen balance

Massive protein catabolism causes negative nitrogen balance where nitrogen losses through urine and wounds exceed nitrogen intake, leading to muscle wasting.

Question 84: Recombinant human growth hormone (rhGH) has been studied in pediatric burn patients to:

Prevent hypertrophic scarring post-healing
Control pain during dressing changes
Accelerate wound healing and reduce hospital length of stay (Correct answer)
Prevent wound infections by enhancing immune response

Correct answer: Accelerate wound healing and reduce hospital length of stay

Recombinant human growth hormone has been shown to accelerate wound healing, enhance protein synthesis, and reduce hospital length of stay in pediatric burn patients.

Question 85: How can nurses support the psychosocial needs of burn patients?

By limiting communication.
By discouraging emotional expression.
By offering emotional support and connecting them with resources (Correct answer)
By focusing only on physical wounds.

Correct answer: By offering emotional support and connecting them with resources

Burn injuries have profound physical and psychological impacts. Nurses support psychosocial needs by providing empathetic emotional support, actively listening to patient concerns, and connecting them with appropriate resources such as psychologists, social workers, or support groups. This holistic approach addresses the emotional trauma, body image issues, and adjustment challenges faced by burn patients.

Question 86: Which urine output target best indicates adequate fluid resuscitation in an adult burn patient?

1–2 mL/kg/hr
0.25–0.5 mL/kg/hr
0.5–1 mL/kg/hr (Correct answer)
2–3 mL/kg/hr

Correct answer: 0.5–1 mL/kg/hr

A urine output of 0.5–1 mL/kg/hr is the standard goal in adult burn resuscitation, reflecting adequate renal perfusion without over-resuscitation.

Question 87: For a critically ill burn patient on insulin, which blood glucose target range is generally recommended?

140–180 mg/dL (Correct answer)
200–250 mg/dL
80–110 mg/dL
60–80 mg/dL

Correct answer: 140–180 mg/dL

A moderate target of about 140–180 mg/dL avoids both hyperglycemia and the hypoglycemia risk of tight control.

Question 88: Which professional may assist with complex psychosocial needs?

Psychologist or social worker (Correct answer)
Physical therapist.
Radiologist.
Dietitian only.

Correct answer: Psychologist or social worker

For complex psychosocial needs, such as severe depression, anxiety, trauma, body image issues, or difficulties with social reintegration, a psychologist or social worker is the most appropriate professional to assist. They provide specialized counseling, therapy, and support services to help patients cope with the emotional and social challenges of burn recovery. These professionals offer expertise beyond general nursing care.

Question 89: Which pharmacological intervention is used to treat opioid-induced pruritus in burn patients?

Nalbuphine (a mixed opioid agonist-antagonist) (Correct answer)
Diphenhydramine 50 mg IV
Lorazepam 1 mg IV
Ketorolac 30 mg IV

Correct answer: Nalbuphine (a mixed opioid agonist-antagonist)

Nalbuphine acts as a mu-receptor antagonist and kappa-receptor agonist, reducing opioid-induced pruritus while preserving analgesia.

Question 90: A burn patient develops Curling's ulcer. Which burn-related mechanism is the primary cause?

Direct chemical injury to gastric mucosa
Hyperacidity from stress response and mucosal ischemia (Correct answer)
Corticosteroid administration
Elevated prostaglandin E2 levels

Correct answer: Hyperacidity from stress response and mucosal ischemia

Curling's ulcer results from splanchnic vasoconstriction and mucosal ischemia combined with increased gastric acid secretion during the stress response.

Question 91: A nurse caring for a burn patient notices the thermostat in the room is set to 28°C (82°F). What is the rationale for this elevated ambient temperature?

To minimize evaporative heat loss and decrease metabolic demand (Correct answer)
To reduce patient anxiety
To improve staff comfort during procedures
To promote bacterial growth suppression

Correct answer: To minimize evaporative heat loss and decrease metabolic demand

Burn patients lose massive amounts of heat through evaporation from open wounds; maintaining a warm environment reduces metabolic demand and hypothermia risk.

Question 92: What type of scar is characterized by raised, firm, erythematous tissue that remains within the original wound boundaries?

Hypertrophic scar (Correct answer)
Contracture
Keloid scar
Atrophic scar

Correct answer: Hypertrophic scar

Hypertrophic scars are raised, firm, and erythematous but stay confined within the original wound margins, unlike keloids which extend beyond them.

Question 93: A burn patient's family member asks for an update by phone. The patient is alert and has not listed this person as an authorized contact. What should the nurse do?

Disclose only the TBSA percentage
Provide general clinical details since it is family
Refer the caller to the hospital's public relations office
Ask the patient for permission before disclosing information (Correct answer)

Correct answer: Ask the patient for permission before disclosing information

Under HIPAA, a capable patient decides who receives their health information, so the nurse should obtain the patient's agreement first.

Question 94: A patient expresses fear of intimacy with their partner after sustaining burns to the trunk. The nurse's FIRST response should be:

Acknowledge the concern and invite the partner to a joint education session (Correct answer)
Reassure the patient that intimacy concerns usually resolve on their own
Document the concern and address it at the next outpatient visit
Refer immediately to a sex therapist

Correct answer: Acknowledge the concern and invite the partner to a joint education session

Acknowledging the concern validates the patient's experience, and including the partner supports open communication and shared coping.

Question 95: Which ABA sepsis criterion is adjusted for burn patients compared to general sepsis definitions?

Blood pressure above 120 systolic
Any white blood cell count above 10,000
Heart rate above 70
Temperature threshold above 39°C or below 36.5°C (Correct answer)

Correct answer: Temperature threshold above 39°C or below 36.5°C

ABA burn sepsis criteria use a temperature above 39°C or below 36.5°C because burn patients have a reset baseline from hypermetabolism.

Question 96: What is the usual daily protein recommendation for an adult with a major burn?

1.5–2.0 g/kg/day (Correct answer)
1.0–1.2 g/kg/day
0.8–1.0 g/kg/day
3.5–4.0 g/kg/day

Correct answer: 1.5–2.0 g/kg/day

Adults with burns need about 1.5–2.0 g/kg/day of protein to offset heavy catabolism and nitrogen loss.

Question 97: Which medication is used to attenuate the hypermetabolic response in burn patients by blocking catecholamine effects?

Dopamine
Epinephrine
Propranolol (Correct answer)
Atropine

Correct answer: Propranolol

Propranolol, a non-selective beta-blocker, attenuates the hypermetabolic response in burn patients by blocking the effects of excess catecholamines released after major burns.

Question 98: During a dressing change, the nurse notes green discoloration and a fruity odor from a burn wound. Which pathogen is most likely responsible?

Pseudomonas aeruginosa (Correct answer)
Klebsiella pneumoniae
Escherichia coli
Proteus mirabilis

Correct answer: Pseudomonas aeruginosa

Pseudomonas aeruginosa produces pyocyanin, causing characteristic blue-green wound discoloration, and secretes enzymes that produce a fruity (grape-like) odor.

Question 99: Which approach is MOST important for CBRN professionals when applying technical procedures?

Adhering to established protocols while adapting to specific conditions (Correct answer)
Applying the same technique in every situation without variation
Using the fastest method available regardless of standards
Following personal shortcuts developed through experience

Correct answer: Adhering to established protocols while adapting to specific conditions

Technical procedures require adherence to established protocols as a foundation, with professional judgment to adapt appropriately to specific conditions. This balance ensures both consistency and effectiveness.

Question 100: Which trace element is commonly depleted in burn patients due to losses through wound exudate and is critical for wound healing?

Phosphorus
Zinc (Correct answer)
Chloride
Sodium

Correct answer: Zinc

Zinc is lost through burn wound exudate and its deficiency impairs wound healing, immune function, and protein synthesis.

Question 101: What is the benefit of involving family in patient education?

It improves understanding and emotional support for the patient (Correct answer)
It makes care more expensive.
It delays discharge.
It complicates the care plan.

Correct answer: It improves understanding and emotional support for the patient

Involving family in patient education is highly beneficial because it enhances their understanding of the patient's condition, care needs, and recovery process. Educated and involved family members can provide crucial emotional support, assist with home care, and advocate for the patient, ultimately contributing to a more positive and successful recovery. This creates a supportive environment for the patient.

Question 102: What role does cultural competency play in patient education?

It complicates the teaching process.
It reduces patient engagement.
It promotes effective communication and patient trust (Correct answer)
It delays recovery.

Correct answer: It promotes effective communication and patient trust

Cultural competency in patient education is crucial because it enables healthcare providers to tailor information and communication methods to align with a patient's cultural beliefs, values, and language preferences. This respectful and individualized approach fosters effective communication, builds trust, and increases the likelihood of patient understanding and adherence to the care plan. It ensures care is patient-centered and effective.

Question 103: Mafenide acetate (Sulfamylon) is preferred over silver sulfadiazine in which clinical scenario?

Electrical burns to the extremities
Burns to the face with minimal eschar
Superficial partial-thickness burns in children
Deep burns with thick eschar requiring penetration (Correct answer)

Correct answer: Deep burns with thick eschar requiring penetration

Mafenide acetate penetrates eschar effectively, making it superior for burns with thick eschar where penetration is critical.

Question 104: Which assessment method provides the MOST reliable data for CBRN professionals making critical decisions?

Social media reviews and testimonials
Single-source data from one stakeholder
Informal verbal feedback alone
Standardized tools combined with professional observation (Correct answer)

Correct answer: Standardized tools combined with professional observation

Combining standardized assessment tools with professional observation provides the most reliable and comprehensive data. Standardized tools ensure consistency and validity, while professional observation captures nuances that tools might miss.

Question 105: Which practice is essential for preventing cross-contamination in burn units?

Using dry wound dressings only.
Minimizing wound cleaning.
Using the same dressing for multiple patients.
Hand hygiene and use of personal protective equipment (PPE) (Correct answer)

Correct answer: Hand hygiene and use of personal protective equipment (PPE)

Hand hygiene and the consistent use of personal protective equipment (PPE) are fundamental practices for preventing cross-contamination in any healthcare setting, especially burn units. Burn wounds are highly vulnerable to infection, and these measures minimize the transfer of microorganisms between patients, staff, and the environment. Strict adherence to these protocols is essential for patient safety and infection prevention.

Question 106: Which organism is most commonly responsible for burn wound sepsis in the first 72 hours post-injury?

Pseudomonas aeruginosa
Candida albicans
Staphylococcus aureus (Correct answer)
Acinetobacter baumannii

Correct answer: Staphylococcus aureus

Gram-positive organisms, especially Staphylococcus aureus, predominate in the early post-burn period before gram-negative colonization occurs.

Question 107: What is the primary goal of infection control in burn patients?

To reduce pain levels.
To reduce morbidity and mortality from infections (Correct answer)
To promote faster rehydration.
To prevent wound dehiscence.

Correct answer: To reduce morbidity and mortality from infections

Burn patients are highly susceptible to infections due to compromised skin barriers and immunosuppression. The primary goal of infection control is to prevent and manage infections, which are a leading cause of morbidity and mortality in this population. Effective infection control measures protect the patient from severe complications and improve their chances of recovery.

Question 108: A burn patient's prealbumin is low, and the nurse also checks the C-reactive protein (CRP). Why?

A high CRP means feeds should stop
CRP predicts how much prealbumin the patient needs
Inflammation lowers prealbumin no matter how well the patient is fed (Correct answer)
CRP measures protein intake directly

Correct answer: Inflammation lowers prealbumin no matter how well the patient is fed

Prealbumin is a negative acute-phase reactant, so a high CRP means a low prealbumin may reflect inflammation rather than poor nutrition.

Question 109: After copious irrigation, which topical treatment is indicated for a hydrofluoric acid burn to the hand?

Silver sulfadiazine
Mineral oil
Sodium bicarbonate paste
Calcium gluconate gel (Correct answer)

Correct answer: Calcium gluconate gel

Calcium gluconate binds fluoride ions, limiting tissue destruction and systemic hypocalcemia.

Question 110: Why is serum albumin considered a poor marker for acute nutritional status in burn patients?

It cannot be measured in burn patients
It only measures fat stores
Its long half-life and negative acute-phase response make it unreliable acutely (Correct answer)
It is unaffected by nutrition

Correct answer: Its long half-life and negative acute-phase response make it unreliable acutely

Albumin has a ~20-day half-life and falls as a negative acute-phase reactant during inflammation regardless of nutritional intake, making it unreliable acutely.

Question 111: When should enteral nutrition ideally be initiated in a major burn patient to reduce hypermetabolism?

Within 24–48 hours of injury (Correct answer)
Only after surgery is completed
After 72 hours when the patient is stabilized
When the patient refuses oral intake

Correct answer: Within 24–48 hours of injury

Early enteral nutrition within 24–48 hours reduces hypermetabolism, preserves gut mucosal integrity, and decreases infection risk.

Question 112: A burn patient develops a temperature of 38.5°C on day 3. What is the most appropriate initial nursing action?

Start broad-spectrum antibiotics empirically
Apply cooling blankets
Obtain blood, wound, and urine cultures before starting antibiotics (Correct answer)
Administer antipyretics immediately

Correct answer: Obtain blood, wound, and urine cultures before starting antibiotics

Cultures must be collected before initiating antibiotics to identify the causative organism and guide therapy.

Question 113: Which central line practice best reduces CLABSI risk in burn patients?

Using povidone-iodine only after the line is placed
Changing lines routinely every 24 hours over a guidewire
Inserting through burned tissue when convenient
Chlorhexidine skin antisepsis and full sterile barrier precautions at insertion (Correct answer)

Correct answer: Chlorhexidine skin antisepsis and full sterile barrier precautions at insertion

Chlorhexidine skin prep with maximal sterile barriers is a core element of the CLABSI prevention bundle.

Question 114: During the ebb phase of the burn stress response, which hemodynamic finding is most expected?

Increased cardiac output
Elevated core temperature
Decreased vascular resistance
Decreased cardiac output (Correct answer)

Correct answer: Decreased cardiac output

The ebb phase (first 48 hours) is characterized by decreased cardiac output, hypoperfusion, and reduced metabolic rate.

Question 115: A burn patient's morning labs show WBC 2,800 cells/µL (down from 18,000 yesterday). What does this leukopenia suggest?

Bone marrow suppression or overwhelming sepsis (Correct answer)
Successful treatment of infection
Normal inflammatory resolution
Steroid therapy effect

Correct answer: Bone marrow suppression or overwhelming sepsis

A sudden drop in WBC to leukopenic levels in a burn patient is an ominous sign indicating bone marrow suppression from overwhelming sepsis or severe systemic illness.

Question 116: What is the primary purpose of custom-fitted compression garments in burn scar rehabilitation?

To reduce acute pain
To prevent fluid shifts
To prevent wound infection
To minimize hypertrophic scar formation (Correct answer)

Correct answer: To minimize hypertrophic scar formation

Compression garments apply 20–25 mmHg of continuous pressure to maturing scars, reducing hypertrophic scar formation by limiting collagen deposition.

Question 117: What is the correct order for donning PPE before entering a contact-isolation burn room?

Gown, mask, eye protection, gloves (Correct answer)
Mask, gloves, gown, eye protection
Gloves, gown, mask, eye protection
Eye protection, gloves, mask, gown

Correct answer: Gown, mask, eye protection, gloves

CDC guidance is gown, mask/respirator, goggles/face shield, then gloves last so they cover the gown cuffs.

Question 118: A patient has a full-thickness burn involving the external ear. Which topical agent is preferred because of its ability to penetrate cartilage and help prevent suppurative chondritis?

Mafenide acetate (Correct answer)
Silver sulfadiazine
Silver nitrate 0.5%
Bacitracin ointment

Correct answer: Mafenide acetate

Mafenide penetrates eschar and cartilage well, which makes it the agent of choice for ear burns at risk for chondritis.

Question 119: How should healthcare providers evaluate patient understanding?

Avoid testing the patient.
Assume the patient understood.
Provide a handout only.
Ask the patient to repeat or demonstrate the information (Correct answer)

Correct answer: Ask the patient to repeat or demonstrate the information

The "teach-back" method, where the patient is asked to repeat or demonstrate the information in their own words, is the most effective way to evaluate patient understanding. This ensures that the patient has truly grasped the instructions and can apply them, rather than simply assuming comprehension or relying on a handout alone. It confirms comprehension and identifies areas needing further clarification.

Question 120: Burn patients are particularly susceptible to hypothermia during wound care. What is the minimum recommended ambient room temperature for dressing changes?

98°F (37°C)
75°F (24°C)
85°F (29°C) (Correct answer)
68°F (20°C)

Correct answer: 85°F (29°C)

Burn patients lose thermoregulatory ability; rooms should be warmed to at least 85°F (29°C) during wound care to prevent hypothermia.

Question 121: Which nutritional route is preferred for burn patients who have a functioning gastrointestinal tract?

Peripheral parenteral nutrition
Total parenteral nutrition (TPN) via central line
Oral diet only when fully awake
Early enteral nutrition via nasogastric tube (Correct answer)

Correct answer: Early enteral nutrition via nasogastric tube

Early enteral nutrition is preferred as it maintains gut integrity, reduces bacterial translocation, and supports the hypermetabolic response.

Question 122: What metabolic complication is most characteristic of the hypermetabolic stress response in severe burn patients?

Hypothermia
Metabolic alkalosis
Hyperglycemia (Correct answer)
Hypoglycemia

Correct answer: Hyperglycemia

Stress hormones (catecholamines, cortisol, glucagon) promote gluconeogenesis and insulin resistance, causing hyperglycemia in burn patients.

Question 123: Silver nitrate solution used in burn wound care can cause which electrolyte imbalance requiring close monitoring?

Hyponatremia and hypochloremia (Correct answer)
Hypercalcemia and hyperphosphatemia
Hyperkalemia and hypercalcemia
Hypernatremia and hyperkalemia

Correct answer: Hyponatremia and hypochloremia

Silver nitrate solution is hypotonic and leaches sodium and chloride from wound tissues, leading to hyponatremia and hypochloremia requiring frequent electrolyte monitoring and replacement.

Question 124: A burn survivor expresses shame about visible facial scarring before returning to work. Which psychosocial intervention is MOST appropriate?

Refer to a peer support specialist who is also a burn survivor (Correct answer)
Prescribe anxiolytics to reduce social anxiety
Advise the patient to delay returning to work until scars mature
Reassure the patient that scars will fade with time

Correct answer: Refer to a peer support specialist who is also a burn survivor

Peer support specialists with lived burn experience provide validated emotional support and practical coping strategies that clinicians alone cannot replicate.

Question 125: When a CBRN professional encounters an unexpected result during a technical procedure, the FIRST action should be to:

Repeat the procedure from the beginning immediately
Stop, assess the situation, and determine whether to proceed or seek guidance (Correct answer)
Report the issue without any preliminary assessment
Continue the procedure and address it later

Correct answer: Stop, assess the situation, and determine whether to proceed or seek guidance

Stopping to assess the situation when unexpected results occur is critical. This allows the professional to evaluate whether it is safe and appropriate to continue, and to determine if additional guidance or resources are needed.
