✍️ Sample CBRN Questions & Answers
1. In Certified Burn Registered Nurse practice, what is the FIRST step when a safety hazard is identified in the workplace?
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.
2. Recombinant human growth hormone (rhGH) has been studied in pediatric burn patients to:
Recombinant human growth hormone has been shown to accelerate wound healing, enhance protein synthesis, and reduce hospital length of stay in pediatric burn patients.
3. How should healthcare providers evaluate patient understanding?
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.
4. Which psychological condition is commonly encountered in burn survivors during the rehabilitation phase?
PTSD is common in burn survivors due to the traumatic injury, painful procedures, and altered body image, requiring integrated psychological support throughout rehabilitation.
5. What metabolic complication is most characteristic of the hypermetabolic stress response in severe burn patients?
Stress hormones (catecholamines, cortisol, glucagon) promote gluconeogenesis and insulin resistance, causing hyperglycemia in burn patients.
6. Which outcome measure is used in burn rehabilitation programs to assess a patient's level of functional independence in self-care and mobility?
The Functional Independence Measure (FIM) scores independence in self-care, mobility, and cognition, making it a key rehabilitation outcome measure in burn programs.
