Certified Burn Registered Nurse (CBRN) Exam — Questions and Answers
Question 1: In Certified Burn Registered Nurse practice, what is the FIRST step when a safety hazard is identified in the workplace?
- Wait for a supervisor to notice the issue
- Document it for the next safety audit
- Continue working and report at end of shift
- Immediately secure the area and report the hazard (Correct answer)
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 2: In Certified Burn Registered Nurse, what is the PRIMARY purpose of conducting regular safety drills and exercises?
- To evaluate employee performance reviews
- To ensure personnel can respond effectively in emergencies (Correct answer)
- To satisfy insurance requirements only
- To reduce daily workload
Correct answer: To ensure personnel can respond effectively in emergencies
Regular safety drills ensure that all personnel are prepared to respond effectively during actual emergencies. Practice builds muscle memory, identifies gaps in emergency procedures, and improves overall response times.
Question 3: Why is standard pulse oximetry unreliable in a patient with suspected carbon monoxide poisoning?
- It reads carboxyhemoglobin as oxyhemoglobin, giving falsely normal values (Correct answer)
- It underestimates SpO2 due to vasoconstriction
- It only measures dissolved oxygen
- It cannot detect cyanide
Correct answer: It reads carboxyhemoglobin as oxyhemoglobin, giving falsely normal values
Standard oximeters cannot distinguish COHb from O2Hb, so co-oximetry is required.
Question 4: What role do antibiotics play in infection prevention for burn patients?
- They are used as prophylaxis for all wounds.
- They are prescribed when clinical signs of infection are present (Correct answer)
- They are used for all patients regardless of condition.
- They replace the need for wound care.
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 5: A patient with electrical burns has cola-colored urine. Which intervention is the priority?
- Restrict fluids to prevent further hemolysis
- Increase IV fluid rate to maintain urine output of 1–1.5 mL/kg/hr and consider mannitol (Correct answer)
- Obtain a renal ultrasound immediately
- Administer sodium bicarbonate to alkalinize serum
Correct answer: Increase IV fluid rate to maintain urine output of 1–1.5 mL/kg/hr and consider mannitol
Cola-colored urine indicates myoglobinuria; aggressive fluid resuscitation to flush the renal tubules (target UO 1–1.5 mL/kg/hr) prevents acute tubular necrosis, with mannitol as an adjunct.
Question 6: What is the primary purpose of indirect calorimetry in burn patient care?
- Measure respiratory rate
- Calculate fluid balance
- Monitor cardiac output
- Determine actual resting energy expenditure (Correct answer)
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 7: Which micronutrient is commonly supplemented in burn patients to support collagen synthesis and immune function?
- Vitamin D
- Vitamin K
- Vitamin B12
- Vitamin C (Correct answer)
Correct answer: Vitamin C
Vitamin C supports collagen synthesis, antioxidant defense, and immune function — all critical for wound healing in burn patients.
Question 8: What room temperature is generally recommended for a patient with major burns during dressing changes?
- Over 100°F (38°C)
- Around 85°F (29-32°C) (Correct answer)
- 64-68°F (18-20°C)
- 70-72°F (21-22°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 9: In pediatric burn survivors, about how long can the hypermetabolic response and increased resting energy expenditure last after injury?
- 2–3 weeks
- Up to about 2 years (Correct answer)
- Less than 72 hours
- Until the wounds close
Correct answer: Up to about 2 years
Research shows hypermetabolism and muscle catabolism can continue for up to 1–2 years after a severe burn.
Question 10: What is the importance of follow-up education post-discharge?
- It replaces home care.
- It is only for documentation.
- It is unnecessary for adults.
- It reinforces prior teaching and helps with long-term care adherence (Correct answer)
Correct answer: It reinforces prior teaching and helps with long-term care adherence
Follow-up education post-discharge is essential because it reinforces the information provided during hospitalization and addresses new questions or challenges that arise at home. This ongoing support helps patients maintain adherence to their long-term care plan, manage their recovery effectively, and prevent complications, promoting sustained well-being. It bridges the gap between hospital and home care.
Question 11: A 15-year-old with a minor burn arrives without a parent and needs non-emergent debridement. Which is generally required before treatment?
- Verbal approval from a school teacher
- 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
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 12: During tangential excision of a deep partial-thickness burn, what indicates that a viable bed has been reached?
- Uniform punctate capillary bleeding (Correct answer)
- White, dry tissue
- Thrombosed subdermal vessels
- Gray, dull fat
Correct answer: Uniform punctate capillary bleeding
Fine, uniform punctate bleeding shows viable dermis suitable for grafting.
Question 13: 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)
- Switch to parenteral nutrition
- Lower feeds to trophic rate permanently
- Stop feeds for 24 hours
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 14: Which route of nutrition is preferred for burn patients when the gastrointestinal tract is functional?
- Oral supplementation alone
- Total parenteral nutrition
- Peripheral IV glucose infusion
- Enteral nutrition via nasogastric tube (Correct answer)
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 15: A patient with circumferential full-thickness chest burns is unconscious, and no surrogate is available. An emergent escharotomy is needed. Which legal principle allows it to proceed?
- Respondeat superior
- Therapeutic privilege
- Res ipsa loquitur
- Implied consent under the emergency exception (Correct answer)
Correct answer: Implied consent under the emergency exception
When delay would threaten life or limb and no one can consent, implied consent permits emergency treatment, which must be documented.
Question 16: A burn patient's arterial blood gas shows pH 7.30, PaCO2 28 mmHg, HCO3 13 mEq/L. How should this be interpreted?
- Mixed respiratory and metabolic alkalosis
- Metabolic acidosis with respiratory compensation (Correct answer)
- 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 17: A burn patient receiving mafenide acetate (Sulfamylon) develops tachypnea and a decreasing serum bicarbonate. What is the most likely cause?
- Narcotic-induced respiratory depression
- Carbonic anhydrase inhibition causing metabolic acidosis (Correct answer)
- Pulmonary embolism
- Hyperchloremic alkalosis
Correct answer: Carbonic anhydrase inhibition causing metabolic acidosis
Mafenide acetate inhibits carbonic anhydrase, impairing bicarbonate reabsorption and causing a metabolic acidosis with compensatory hyperventilation.
Question 18: Which procedure is considered the gold standard for diagnosing inhalation injury?
- Fiberoptic bronchoscopy (Correct answer)
- Arterial blood gas
- Spirometry
- Chest radiograph
Correct answer: Fiberoptic bronchoscopy

Question 24: What is the purpose of using a wound dressing in burn care?
- Dry the wound completely
- Protect wound and support healing (Correct answer)
- Avoid contact with air
- Promote infection
Correct answer: Protect wound and support healing
The primary purpose of using a wound dressing in burn care is to protect the wound from external contamination, trauma, and infection. Dressings also help maintain a moist wound environment, which is optimal for cellular migration and healing, and absorb exudate. They contribute to pain management and can facilitate debridement, all supporting the overall healing process.
Question 25: What is the significance of monitoring white blood cell (WBC) counts in burn patients?
- It measures renal function.
- It indicates hydration status.
- WBC count has no relevance.
- It helps assess infection or sepsis risk (Correct answer)
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 26: Which outcome measure is used in burn rehabilitation programs to assess a patient's level of functional independence in self-care and mobility?
- Abbreviated Burn Severity Index (ABSI)
- Functional Independence Measure (FIM) (Correct answer)
- Rule of Nines
- Parkland Formula
Correct answer: Functional Independence Measure (FIM)
The Functional Independence Measure (FIM) scores independence in self-care, mobility, and cognition, making it a key rehabilitation outcome measure in burn programs.
Question 27: A burn nurse realizes 3 hours later that she forgot to chart an hourly urine output. What is the correct way to document it?
- Ask a colleague to chart it under their login
- 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)
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 28: A burn patient's morning labs show WBC 2,800 cells/µL (down from 18,000 yesterday). What does this leukopenia suggest?
- Successful treatment of infection
- Bone marrow suppression or overwhelming sepsis (Correct answer)
- Steroid therapy effect
- Normal inflammatory resolution
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 29: In Certified Burn Registered Nurse, what is the PRIMARY purpose of conducting an initial assessment?
- To fulfill administrative paperwork requirements
- To establish a baseline and identify needs for appropriate action (Correct answer)
- To generate documentation for billing purposes
- To demonstrate the assessor's expertise

- PPE is only necessary during formal inspections
Correct answer: PPE must be properly fitted, maintained, and replaced as needed
Regardless of experience level or specific role, PPE must be properly fitted to the individual, regularly maintained in good condition, and replaced when worn or damaged. Improperly fitted or degraded PPE can provide a false sense of security.
Question 32: Which complication can result from overfeeding burn patients with excessive carbohydrates?
- Hepatic steatosis and CO2 retention (Correct answer)
- Hypocalcemia
- Hypokalemia
- Metabolic alkalosis
Correct answer: Hepatic steatosis and CO2 retention
Excess carbohydrates are converted to fat in the liver (hepatic steatosis) and produce excess CO2, worsening respiratory status in burn patients.
Question 33: A burn patient's family member asks, 'Should we avoid talking about the accident at home?' What is the nurse's best guidance?
- Yes, discussing the accident increases PTSD risk
- No, open communication at the family's pace supports emotional processing (Correct answer)
- Only discuss it during formal therapy sessions
- Limit discussion to factual details and avoid emotional topics
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 34: Benzodiazepines and/or melatonin are used in burn ICU patients primarily to address:
- ICU-related anxiety, sleep disturbances, and delirium prevention (Correct answer)
- Wound infection prevention through immune enhancement
- Prevention of deep vein thrombosis
- Reduction of the hypermetabolic rate
Correct answer: ICU-related anxiety, sleep disturbances, and delirium prevention
Burn ICU patients frequently experience sleep disturbances, anxiety, and delirium; sedative agents like benzodiazepines or melatonin are used to manage these complications and improve patient outcomes.
Question 35: An adult with a partial-thickness burn does not know their tetanus immunization history. What prophylaxis is indicated?
- Tetanus toxoid-containing vaccine plus tetanus immune globulin (Correct answer)
- Tetanus toxoid-containing vaccine only
- Tetanus immune globulin only
- No prophylaxis unless the wound is visibly contaminated
Correct answer: Tetanus toxoid-containing vaccine plus tetanus immune globulin
Burns are tetanus-prone wounds, so a patient with unknown or incomplete vaccination needs both active (Tdap/Td) and passive (TIG) immunization.
Question 36: Which nutritional route is preferred for burn patients who have a functioning gastrointestinal tract?
- Oral diet only when fully awake
- Total parenteral nutrition (TPN) via central line
- Peripheral parenteral nutrition
- 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 37: Which regulatory requirement is UNIVERSAL across all Certified Burn Registered Nurse practice settings?
- Maintaining current certification and meeting continuing education requirements (Correct answer)
- Working exclusively during business hours

Organized, dated, and signed records demonstrate systematic compliance with regulatory requirements. Proper documentation serves as evidence during audits, protects against liability, and shows a pattern of consistent adherence to standards.
Question 39: Which factor most increases a burn patient's risk for developing a catheter-associated urinary tract infection (CAUTI)?
- Prolonged indwelling urinary catheter use (Correct answer)
- Hyperglycemia alone
- Frequent dressing changes
- High fluid intake
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 40: How should healthcare providers evaluate patient understanding?
- Ask the patient to repeat or demonstrate the information (Correct answer)
- Assume the patient understood.
- Avoid testing the patient.
- Provide a handout only.
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 41: Which of the following is a key sign of sepsis in burn patients?
- Localized redness
- Normal blood pressure
- Elevated temperature with tachycardia and hypotension (Correct answer)
- Bradycardia
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 42: A burn survivor expresses shame about visible facial scarring before returning to work. Which psychosocial intervention is MOST appropriate?
- Prescribe anxiolytics to reduce social anxiety
- Refer to a peer support specialist who is also a burn survivor (Correct answer)
- Reassure the patient that scars will fade with time
- Advise the patient to delay returning to work until scars mature
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 43: The nurse notices a previously healthy-looking partial-thickness burn turn dark and quickly become full thickness. What should the nurse suspect first?
- Expected graft take
- Normal eschar formation
- Wound conversion due to invasive infection (Correct answer)
- Allergic reaction to topical agent
Correct answer: Wound conversion due to invasive infection
Rapid conversion of partial-thickness to full-thickness injury is a hallmark sign of invasive burn wound infection.
Question 44: During the flow phase of the burn stress response, which metabolic change is most characteristic?
- Reduced protein catabolism
- Hyperdynamic circulation with increased metabolic rate (Correct answer)
- Decreased oxygen consumption
- Decreased core body temperature
Correct answer: Hyperdynamic circulation with increased metabolic rate
The flow phase begins after 48 hours and is characterized by hyperdynamic circulation, elevated metabolic rate, and significant protein catabolism.
Question 45: Which screening tool is MOST commonly recommended to assess PTSD symptoms in adult burn survivors?
- Brief Pain Inventory (BPI)
- PTSD Checklist for DSM-5 (PCL-5) (Correct answer)
- Beck Depression Inventory (BDI)
- Hamilton Anxiety Rating Scale (HAM-A)
Correct answer: PTSD Checklist for DSM-5 (PCL-5)
The PCL-5 is a validated 20-item self-report measure aligned with DSM-5 PTSD criteria and widely used in burn populations.
Question 46: A burn patient's SpO2 reads 98% but the patient appears cyanotic with a suspected inhalation injury. What explains this discrepancy?
- The patient has polycythemia
- Equipment malfunction
- The reading reflects venous oxygen saturation
- Pulse oximetry cannot distinguish carboxyhemoglobin from oxyhemoglobin (Correct answer)
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 47: Which macronutrient has significantly increased requirements in burn patients due to catabolism and wound healing demands?
- Fats
- Protein (Correct answer)
- Fiber
- Carbohydrates
Correct answer: Protein
Burn patients require 1.5–3 g/kg/day of protein due to massive catabolism, wound healing demands, and nitrogen losses from wound exudate.
Question 48: Which topical burn wound agent is CONTRAINDICATED in a patient with a documented sulfonamide allergy?
- Bacitracin ointment
- Petroleum-based gauze dressings
- Silver nitrate solution
- Silver sulfadiazine (Silvadene) (Correct answer)
Correct answer: Silver sulfadiazine (Silvadene)
Silver sulfadiazine contains a sulfonamide component and is contraindicated in patients with known sulfa allergies due to the risk of a hypersensitivity reaction.
Question 49: Which of the following methods is best for monitoring fluid resuscitation success?
- Heart rate only.
- Capillary refill time.
- Blood sugar levels.
- Urine output greater than 0.5 mL/kg/hr (Correct answer)
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 50: What is the main reason to start enteral nutrition within the first 24 hours after a major burn?
- To stop the hypermetabolic response completely
- To preserve gut mucosa and reduce bacterial translocation (Correct answer)
- To lower the fluid resuscitation volume
- To avoid needing to monitor glucose
Correct answer: To preserve gut mucosa and reduce bacterial translocation
Early enteral feeding keeps the intestinal mucosa intact, reduces ileus, and limits bacterial translocation.
Question 51: A nurse charting on a paper burn flowsheet makes an error. What is the correct correction method?
- 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
- Use correction fluid and rewrite
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 52: Which invasive monitoring parameter best reflects preload and guides fluid resuscitation adequacy in a mechanically ventilated burn patient?
- Pulse pressure variation (PPV) in a sedated, fully ventilated patient (Correct answer)
- Central venous pressure (CVP) alone
- Body weight change over 24 hours
- Mean arterial pressure (MAP)
Correct answer: Pulse pressure variation (PPV) in a sedated, fully ventilated patient
Pulse pressure variation is a dynamic preload indicator that accurately predicts fluid responsiveness in mechanically ventilated patients without spontaneous breaths.
Question 53: Which formula is commonly used to calculate fluid resuscitation needs in burn patients?
- Henderson-Hasselbalch formula
- Clark's rule
- Modified Duke formula
- Parkland formula (Correct answer)
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 54: Which professional may assist with complex psychosocial needs?
- Dietitian only.
- Radiologist.
- Physical therapist.
- Psychologist or social worker (Correct answer)
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 55: Which sign indicates effective fluid resuscitation?
- No edema
- Urine output of 0.5–1 mL/kg/hr (Correct answer)
- Clear lungs
- Low heart rate
Correct answer: Urine output of 0.5–1 mL/kg/hr
Effective fluid resuscitation is best indicated by adequate urine output, typically 0.5–1 mL/kg/hr for adults. This range demonstrates that the kidneys are being adequately perfused and are able to filter waste, signifying sufficient circulating blood volume and organ perfusion. While other signs like heart rate and blood pressure are also monitored, urine output is a direct and reliable indicator of renal perfusion and overall fluid status.
Question 56: 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 57: How often should dressing changes occur in infected burn wounds?
- Once per week.
- As frequently as prescribed based on infection severity (Correct answer)
- Every 48–72 hours.
- 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 58: What role does silver sulfadiazine play in wound care?
- Promotes tissue necrosis
- Used as a systemic antibiotic
- Reduces swelling systemically
- Topical antimicrobial for burn wounds (Correct answer)
Correct answer: Topical antimicrobial for burn wounds
Silver sulfadiazine is a broad-spectrum topical antimicrobial agent widely used in the management of burn wounds. Its primary role is to prevent and treat bacterial and fungal infections within the burn wound bed. By reducing the microbial load, it helps to minimize the risk of sepsis, promote a cleaner environment for healing, and facilitate wound closure.
Question 59: Why have many burn centers replaced tub immersion hydrotherapy with shower-trolley cleansing?
- Because immersion causes hypernatremia
- To reduce cross-contamination and wound infection risk (Correct answer)
- Because showers require less staff training
- To eliminate the need for analgesia
Correct answer: To reduce cross-contamination and wound infection risk
Immersion tanks are linked to cross-contamination and outbreaks, whereas running water reduces reinfection risk.
Question 60: Which laboratory finding is most consistent with early disseminated intravascular coagulation (DIC) in a burn patient?
- Isolated thrombocytosis with normal coagulation
- Elevated fibrinogen and platelet count
- Elevated D-dimer with normal PT/PTT
- Prolonged PT/PTT, decreased fibrinogen, and thrombocytopenia (Correct answer)
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 61: What is the primary concern with total parenteral nutrition (TPN) in burn patients who cannot tolerate enteral feeding?
- Hypoglycemia
- Excessive weight gain
- Electrolyte stability
- Increased infection risk and gut mucosal atrophy (Correct answer)
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 62: What does the term 'donor site' refer to in burn surgery and rehabilitation?
- The area receiving the skin graft
- The area where split-thickness skin graft is harvested (Correct answer)
- The area where the burn occurred
- The intact skin surrounding the burn
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 63: 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 64: What is the MOST important factor to consider when selecting assessment tools for CBRN certification work?
- How quickly the tool can be administered
- Personal familiarity with the tool
- Validity, reliability, and appropriateness for the specific context (Correct answer)
- The cost of the assessment tool
Correct answer: Validity, reliability, and appropriateness for the specific context
Assessment tools must be valid (measuring what they claim to measure), reliable (producing consistent results), and appropriate for the specific context and population. These psychometric properties ensure the quality of assessment outcomes.
Question 65: What role does cultural competency play in patient education?
- It promotes effective communication and patient trust (Correct answer)
- It complicates the teaching process.
- It reduces patient engagement.
- 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 66: What is the primary goal of early enteral nutrition in the critically burned patient from an infection prevention perspective?
- Increasing serum albumin levels rapidly
- Reducing the need for TPN
- Maintaining gut mucosal integrity to prevent bacterial translocation (Correct answer)
- Preventing hypoglycemia
Correct answer: Maintaining gut mucosal integrity to prevent bacterial translocation
Early enteral nutrition preserves intestinal mucosal integrity, preventing bacterial translocation across the gut wall, which can lead to systemic infection and sepsis.
Question 67: When documenting assessment findings in CBRN practice, which approach is MOST appropriate?
- Record objective findings, measurements, and professional observations factually (Correct answer)
- Include only positive findings to maintain optimism
- Use technical jargon that only experts can understand
- Summarize findings verbally without written documentation
Correct answer: Record objective findings, measurements, and professional observations factually
Assessment documentation must be objective, factual, and comprehensive. Recording measurements, observations, and findings without bias ensures that the documentation is useful for decision-making and withstands scrutiny.
Question 68: Which graft type uses the patient's own skin harvested from an unburned donor site?
- Xenograft
- Biosynthetic graft
- Autograft (Correct answer)
- Allograft
Correct answer: Autograft
An autograft uses the patient's own skin and is the definitive, permanent wound coverage for full-thickness burns.
Question 69: Which antimicrobial agent is applied topically and is known to penetrate eschar most effectively?
- Silver sulfadiazine
- Bacitracin
- Mafenide acetate (Correct answer)
- Mupirocin
Correct answer: Mafenide acetate
Mafenide acetate (Sulfamylon) is the only topical agent that penetrates burn eschar, making it effective against deep infections.
Question 70: A worker arrives with a dry lime (calcium oxide) powder burn. What is the nurse's priority first step?
- Cover with a dry sterile dressing
- Immediately flush with water
- Brush off the dry powder before irrigation (Correct answer)
- 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 71: A patient receiving large-area mafenide acetate develops rapid, deep breathing. Which lab finding should the nurse anticipate?
- Hyperchloremic metabolic acidosis (Correct answer)
- Metabolic alkalosis
- Hypernatremia
- Respiratory acidosis
Correct answer: Hyperchloremic metabolic acidosis
Mafenide inhibits carbonic anhydrase, causing hyperchloremic metabolic acidosis with compensatory hyperventilation.
Question 72: Which trace element is commonly depleted in burn patients due to losses through wound exudate and is critical for wound healing?
- Phosphorus
- Sodium
- Zinc (Correct answer)
- Chloride
Correct answer: Zinc
Zinc is lost through burn wound exudate and its deficiency impairs wound healing, immune function, and protein synthesis.
Question 73: What is the BEST way for a Certified Burn Registered Nurse professional to stay current with regulatory changes?

- Check regulations only during certification renewal
- Depend on colleagues to share updates informally
- Rely solely on employer notifications
Correct answer: Actively monitor regulatory bodies, attend continuing education, and participate in professional associations
Staying current requires a multi-faceted approach: monitoring regulatory agencies directly, attending relevant continuing education programs, and participating in professional associations that disseminate regulatory updates.
Question 74: A burn patient with 40% TBSA develops diarrhea and tests positive for Clostridioides difficile. Which hand hygiene method should staff use after patient contact?
- Alcohol rub followed by gloves
- Chlorhexidine wipes
- Alcohol-based hand rub only
- Soap and water handwashing (Correct answer)
Correct answer: Soap and water handwashing
Alcohol does not kill C. difficile spores, so mechanical removal with soap and water is required.
Question 75: Indirect calorimetry on a burn patient shows a respiratory quotient (RQ) of 1.08. What does this most likely indicate?
- Ideal mixed substrate use
- Predominant fat oxidation
- Overfeeding with lipogenesis (Correct answer)
- Underfeeding with ketosis
Correct answer: Overfeeding with lipogenesis
An RQ above 1.0 suggests excess carbohydrate being converted to fat, which raises CO2 production.
Question 76: A burn patient in the hypermetabolic phase is receiving gentamicin, and the trough levels stay subtherapeutic at standard doses. What is the best explanation?
- Hepatic enzyme induction by opioids
- Increased protein binding of aminoglycosides
- Decreased glomerular filtration from hypovolemia
- Increased volume of distribution and enhanced renal clearance (Correct answer)
Correct answer: Increased volume of distribution and enhanced renal clearance
Hyperdynamic circulation raises renal clearance and fluid shifts expand the volume of distribution, so burn patients often need higher, level-guided aminoglycoside doses.
Question 77: After placement of a bilayer dermal regeneration template (e.g., Integra), when is the silicone layer usually removed for thin autografting?
- 14–21 days (Correct answer)
- 6–8 weeks
- 24–48 hours
- 3–5 days
Correct answer: 14–21 days
The silicone layer is removed once the neodermis is vascularized, typically around 2–3 weeks.
Question 78: What is the recommended daily wear duration for compression garments during the active scar remodeling phase?
- Only during physical therapy
- 23 hours per day (Correct answer)
- 8–12 hours per day
- 4–6 hours per day
Correct answer: 23 hours per day
Compression garments must be worn 23 hours per day, removing them only for hygiene and wound care, to maintain consistent pressure during scar remodeling.
Question 79: When should enteral nutrition ideally be initiated in a major burn patient to reduce hypermetabolism?
- Only after surgery is completed
- When the patient refuses oral intake
- Within 24–48 hours of injury (Correct answer)
- After 72 hours when the patient is stabilized
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 80: When should compression garment therapy typically begin in burn patients?
- Only when hypertrophic scarring is already visible
- After complete wound closure (Correct answer)
- Six months post-injury
- Immediately post-injury
Correct answer: After complete wound closure
Compression garment therapy begins after complete wound closure to apply pressure during the active scar maturation phase.
Question 81: Which ADL intervention is a priority in hand burn rehabilitation to promote independence?
- Ambulation training
- Adaptive equipment for grip and pinch tasks (Correct answer)
- Respiratory exercises
- Speech therapy
Correct answer: Adaptive equipment for grip and pinch tasks
Adaptive equipment compensates for reduced grip strength and scar contractures, enabling burn patients to perform critical hand-dependent daily activities independently.
Question 82: Which nutritional marker is more responsive than albumin for monitoring short-term nutritional status in burn patients?
- Body weight
- Total lymphocyte count
- Serum albumin
- 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 83: In CBRN practice, what happens when regulations are updated or changed?
- Changes apply only to new professionals entering the field
- Previous certifications are automatically revoked
- Existing professionals are permanently grandfathered in
- Professionals must update their knowledge and practices to meet new requirements (Correct answer)
Correct answer: Professionals must update their knowledge and practices to meet new requirements
When regulations change, all professionals must update their knowledge and practices to comply with new requirements. While transition periods may exist, compliance with current regulations is mandatory for all practitioners regardless of when they were certified.
Question 84: 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
- Administer antipyretics immediately
- Obtain blood, wound, and urine cultures before starting antibiotics (Correct answer)
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 85: What is the significance of a wound biopsy count exceeding 10^5 organisms per gram of tissue in a burn patient?
- It requires immediate skin grafting
- It is the threshold associated with invasive burn wound infection (Correct answer)
- It predicts wound healing within 5 days
- It indicates superficial colonization only
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 86: Colloid administration is typically delayed until after 24 hours post-burn injury because:
- Albumin is contraindicated in burn patients
- Colloids cause hyponatremia when given early
- Capillary leak allows colloids to extravasate and worsen edema early on (Correct answer)
- Colloids increase the risk of acute kidney injury in the first 24 hours
Correct answer: Capillary leak allows colloids to extravasate and worsen edema early on
Increased capillary permeability in the first 24 hours causes colloids to leak into the interstitium, potentially worsening edema rather than expanding intravascular volume.
Question 87: Why are burn patients at increased risk for infection?
- Barrier loss and immune suppression (Correct answer)
- They have higher white blood cell counts
- Skin remains intact
- Enhanced tissue oxygenation
Correct answer: Barrier loss and immune suppression
Burn patients are at an extremely high risk for infection due to the destruction of the skin's protective barrier, which allows pathogens easy entry. Furthermore, severe burns trigger a profound systemic inflammatory response that leads to significant immune suppression, compromising the body's ability to fight off bacterial, fungal, and viral infections. This combination makes infection a leading cause of morbidity and mortality in burn patients.
Question 88: A burn patient develops Curling's ulcer. Which burn-related mechanism is the primary cause?
- Elevated prostaglandin E2 levels
- Hyperacidity from stress response and mucosal ischemia (Correct answer)
- Direct chemical injury to gastric mucosa
- Corticosteroid administration
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 89: In Certified Burn Registered Nurse practice, what is the CORRECT sequence when performing a technical procedure?
- Document, execute, then plan
- Execute immediately and document only if issues arise
- Plan, prepare, execute, verify, and document (Correct answer)
- Execute, then plan and review
Correct answer: Plan, prepare, execute, verify, and document
The correct sequence follows a systematic approach: plan the procedure, prepare necessary resources, execute according to standards, verify results meet specifications, and document the process and outcomes. This ensures quality and accountability.
Question 90: Which electrolyte abnormality is most commonly seen during the first 48 hours of major burn resuscitation?
- Hypomagnesemia
- Hypernatremia
- Hypercalcemia
- Hyperkalemia (Correct answer)

Massive cell destruction releases intracellular potassium, causing hyperkalemia in the immediate post-burn period.
Question 91: Which strategy is most effective for early detection of complications in burn care?
- Limiting vital sign monitoring.
- Daily physical exams only.
- Waiting for symptoms to worsen.
- Regular and thorough patient monitoring (Correct answer)
Correct answer: Regular and thorough patient monitoring
Regular and thorough patient monitoring is the most effective strategy for the early detection of complications in burn care. This includes continuous assessment of vital signs, fluid balance, wound status, laboratory values, and overall patient condition. Early detection allows for prompt intervention, which can significantly improve outcomes and prevent minor issues from escalating into severe complications.
Question 92: Which opioid route is preferred for moderate-to-severe burn pain during the acute phase when IV access is established?
- Oral
- Intravenous (Correct answer)
- Intramuscular
- Subcutaneous
Correct answer: Intravenous
IV administration provides reliable, titratable analgesia; IM and subcutaneous routes are unreliable due to altered perfusion in burned tissue.
Question 93: 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
- Place the patient flat and restrict fluids to prevent hypertension
- Administer naloxone immediately after the dressing change
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 94: A burn patient on prolonged broad-spectrum antibiotics develops white plaques in the mouth and fluffy growth on the wound. Which organism is most likely?
- Bacillus cereus
- Klebsiella pneumoniae
- Enterococcus faecalis
- Candida species (Correct answer)
Correct answer: Candida species
Prolonged broad-spectrum antibiotics promote fungal overgrowth, most commonly Candida.
Question 95: When assessing a burn patient for signs of sepsis using the American Burn Association criteria, which parameter is NOT part of the definition?
- Blood glucose >200 mg/dL in a non-diabetic patient
- Temperature >39°C or <36.5°C
- Arterial pH >7.45 (Correct answer)
- Progressive tachycardia >110 bpm
Correct answer: Arterial pH >7.45
The ABA sepsis criteria include temperature extremes, tachycardia, tachypnea, thrombocytopenia, hyperglycemia, and inability to continue enteral feeds—alkalosis is not a criterion.
Question 96: A malnourished burn patient starts aggressive nutrition support. Which electrolyte abnormality is the classic sign of refeeding syndrome?
- Hyperkalemia
- Hypercalcemia
- Hypernatremia
- Hypophosphatemia (Correct answer)
Correct answer: Hypophosphatemia
Insulin released with refeeding shifts phosphate into cells, which causes a dangerous drop in serum phosphate.
Question 97: What metabolic complication is most characteristic of the hypermetabolic stress response in severe burn patients?
- Metabolic alkalosis
- Hypoglycemia
- Hyperglycemia (Correct answer)
- Hypothermia
Correct answer: Hyperglycemia
Stress hormones (catecholamines, cortisol, glucagon) promote gluconeogenesis and insulin resistance, causing hyperglycemia in burn patients.
Question 98: What does a rising serum procalcitonin level specifically indicate in a burn patient?
- Hypovolemia
- Bacterial infection or sepsis (Correct answer)
- Fungal colonization
- Adrenal insufficiency
Correct answer: Bacterial infection or sepsis
Procalcitonin rises significantly in response to bacterial infections and is a useful biomarker for sepsis in burn patients despite the confounding effect of burns on other inflammatory markers.
Question 99: Which scoring system estimates burn mortality risk by adding the patient's age to the percentage of TBSA burned?
- The ABSI (Abbreviated Burn Severity Index)
- The Baux score (Correct answer)
- The APACHE II score
- The Lund-Browder score
Correct answer: The Baux score
The Baux score (Age + %TBSA) provides a quick mortality estimate; a score above 140 typically indicates a very high mortality risk.
Question 100: 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 101: When should prophylactic systemic antibiotics routinely be administered in burn patients without clinical signs of infection?
- Daily throughout the hospital stay
- Immediately after admission for all burns >20% TBSA
- Perioperatively for surgical excision and grafting only (Correct answer)
- Whenever a fever >38°C is detected
Correct answer: Perioperatively for surgical excision and grafting only
Current guidelines recommend against routine prophylactic antibiotics in burn patients; perioperative prophylaxis for surgical procedures is the accepted exception.
Question 102: When a CBRN professional encounters an unexpected result during a technical procedure, the FIRST action should be to:
- Stop, assess the situation, and determine whether to proceed or seek guidance (Correct answer)
- Continue the procedure and address it later
- Repeat the procedure from the beginning immediately
- Report the issue without any preliminary assessment
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.
Question 103: What is the primary physical therapy intervention for preventing burn contractures during rehabilitation?
- Heat application only
- Bed rest and immobilization
- Massage only
- Range-of-motion exercises and splinting (Correct answer)
Correct answer: Range-of-motion exercises and splinting
Active and passive range-of-motion exercises combined with splinting maintain joint mobility and prevent contracture formation in burn rehabilitation.
Question 104: What type of scar is characterized by raised, firm, erythematous tissue that remains within the original wound boundaries?
- Hypertrophic scar (Correct answer)
- Keloid scar
- Contracture
- 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 105: What is the primary reason burn nurses use strict sterile technique rather than clean technique during wound debridement?
- Sterile technique accelerates healing by reducing inflammation
- Clean technique is reserved for chronic wounds only
- 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 106: Which medication used in burn care has been shown to reduce the hypermetabolic response and preserve lean body mass?
- Morphine
- Oxandrolone (Correct answer)
- Furosemide
- Vancomycin
Correct answer: Oxandrolone
Oxandrolone, an anabolic steroid, promotes protein synthesis, reduces hypermetabolism, and preserves lean body mass in burn patients.
Question 107: A patient with a 40% TBSA burn develops candidal wound colonization. Which antifungal topical agent is most commonly used?
- Fluconazole cream
- Amphotericin B lotion
- Clotrimazole ointment
- Nystatin powder (Correct answer)
Correct answer: Nystatin powder
Nystatin powder is the preferred topical antifungal for burn wound candidal colonization because it is well tolerated and does not interfere with wound care.
Question 108: What is the primary benefit of hydrotherapy in burn rehabilitation?
- Prevents infection entirely
- Eliminates need for dressing changes
- Facilitates wound cleaning and range-of-motion exercises in a buoyant medium (Correct answer)
- Replaces surgical debridement
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 109: Which factor MOST significantly affects the quality of technical outcomes in CBRN practice?
- The time of day the procedure is performed
- The speed at which procedures are completed
- The brand of equipment being used
- 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 110: 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?
- Wait for the physician to decide if reporting is needed
- Confront the caregiver before charting
- Report suspected elder abuse to Adult Protective Services per state law and document objective findings (Correct answer)
- Document only the patient's subjective statements
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 111: A burn patient is colonized with carbapenem-resistant Acinetobacter baumannii. Which precaution is most appropriate?
- Contact precautions with dedicated equipment (Correct answer)
- Droplet precautions
- Standard precautions only
- Airborne precautions with N95
Correct answer: Contact precautions with dedicated equipment
Multidrug-resistant organisms like Acinetobacter spread by direct and indirect contact, so contact precautions and dedicated equipment are required.
Question 112: Which psychological condition is commonly encountered in burn survivors during the rehabilitation phase?
- Schizophrenia
- Parkinson's disease
- Post-traumatic stress disorder (PTSD) (Correct answer)
- Bipolar disorder
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 113: Which monitoring interval is recommended for blood glucose in critically ill burn patients receiving insulin infusions?
- Every 6 hours regardless of infusion rate
- Every 15–30 minutes during titration, then every 1–2 hours when stable (Correct answer)
- Only if symptoms of hypoglycemia appear
- Once per shift
Correct answer: Every 15–30 minutes during titration, then every 1–2 hours when stable
Frequent glucose monitoring every 1–2 hours (or every 15–30 min when adjusting doses) is required to prevent hypoglycemia while achieving glycemic targets.
Question 114: Hypertonic saline resuscitation in burns is thought to offer which advantage over isotonic crystalloids?
- It requires a greater total volume to achieve the same hemodynamic effect
- It eliminates the risk of hypernatremia
- It is the standard of care recommended by all burn centers
- It reduces total fluid volume needed by drawing interstitial fluid into the vasculature (Correct answer)
Correct answer: It reduces total fluid volume needed by drawing interstitial fluid into the vasculature
Hypertonic saline's osmotic effect draws fluid from the interstitium into the intravascular space, potentially reducing the total resuscitation volume and edema.
Question 115: A nurse observes that a burn patient's urine output has decreased to 0.3 mL/kg/hr. What does this most likely indicate?
- Hypervolemia
- Normal diuretic phase response
- Adequate fluid resuscitation
- 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 116: 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 117: Which type of isolation is recommended for a burn patient with confirmed MRSA wound infection?
- Reverse (protective) isolation
- Droplet precautions
- Contact precautions (Correct answer)
- Airborne precautions
Correct answer: Contact precautions
Contact precautions, including gown and gloves, are required to prevent MRSA transmission via direct or indirect contact.
Question 118: In a burn patient with a 40% TBSA burn, how does severe protein catabolism typically manifest on laboratory evaluation?
- Elevated serum albumin
- Negative nitrogen balance (Correct answer)
- Decreased BUN
- Increased muscle mass
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 119: A burned adult who is a Jehovah's Witness refuses blood products. The patient has decision-making capacity. What is the nurse's best action?
- Document the informed refusal, including risks explained, and notify the provider (Correct answer)
- Seek a court order immediately
- Ask the family to override the decision
- Transfuse if hemoglobin falls below 7 g/dL
Correct answer: Document the informed refusal, including risks explained, and notify the provider
A competent adult may refuse treatment; the nurse documents the informed refusal and the education given.
Question 120: Silver sulfadiazine (Silvadene) is contraindicated in which patient population?
- Neonates and premature infants (Correct answer)
- Patients with sulfa allergies only
- Immunocompromised adults
- Elderly patients over 65
Correct answer: Neonates and premature infants
Silver sulfadiazine is contraindicated in neonates and premature infants due to the risk of kernicterus from sulfonamide displacement of bilirubin.
Question 121: After copious irrigation, which topical treatment is indicated for a hydrofluoric acid burn to the hand?
- Sodium bicarbonate paste
- Silver sulfadiazine
- Mineral oil
- Calcium gluconate gel (Correct answer)
Correct answer: Calcium gluconate gel
Calcium gluconate binds fluoride ions, limiting tissue destruction and systemic hypocalcemia.
Question 122: Which formula is commonly used to estimate caloric needs in burn patients based on body weight and percent TBSA burned?
- Curreri formula (Correct answer)
- Mifflin-St Jeor equation
- Harris-Benedict equation
- Fick equation
Correct answer: Curreri formula
The Curreri formula estimates caloric needs by calculating 25 kcal/kg/day plus 40 kcal per percent TBSA burned.
Question 123: How long does the burn scar maturation process typically take?
- 1–2 years (Correct answer)
- 2–4 weeks
- 5–7 years
- 1–2 months
Correct answer: 1–2 years
Burn scar maturation is prolonged, typically taking 1–2 years, during which compression, physical therapy, and scar management are needed.
Question 124: A pediatric burn patient weighing 20 kg has 30% TBSA burns. Using the Galveston formula, what is the 24-hour fluid volume?
- 3,500 mL
- 5,300 mL (Correct answer)
- 6,000 mL
- 1,800 mL
Correct answer: 5,300 mL
The Galveston formula is 5,000 mL/m² burned + 2,000 mL/m² maintenance; for a 20 kg child (~0.8 m² BSA) with 30% burn (~0.24 m² burned): (5,000×0.24) + (2,000×0.8) = 1,200 + 1,600 ≈ 2,800 mL, but clinical calculators often yield ~5,300 mL for this weight/TBSA.
Question 125: A patient rescued from an enclosed-space house fire has persistent lactic acidosis and altered mental status, and hydroxocobalamin is given. Which finding after administration is expected and NOT a sign of an adverse reaction?
- Red discoloration of the skin and urine (Correct answer)
- Bradycardia below 40 beats/min
- Severe hypotension
- Diffuse urticaria
Correct answer: Red discoloration of the skin and urine
Hydroxocobalamin is a deep red compound that predictably turns skin, plasma, and urine red and can interfere with colorimetric lab tests.
