TNCC - Trauma Nurse Core Curriculum Disaster Management Questions and Answers

Question 1

During a mass casualty incident caused by a bus rollover, you are triaging a 30-year-old male using the START algorithm. The patient is unable to walk. He is apneic. You manually open his airway, and he begins to breathe at a rate of 22 breaths/min. What is the next immediate action and corresponding triage category?

Accepted Answer

Tag the patient as RED (Immediate) and move to the next victim.

Answer

According to the START triage algorithm, if an apneic adult patient begins to breathe after their airway is opened, they are considered to have a compromised airway and are immediately categorized as RED (Immediate) to receive life-saving care. No further assessment (perfusion or mental status) is needed at this stage of primary triage.

Question 2

Which of the following scenarios is a recognized exception to standard mass casualty triage principles, requiring the use of "reverse triage"?

Accepted Answer

A multiple-victim lightning strike.

Answer

In a multiple-victim lightning strike, reverse triage is the standard of care. Victims who are in cardiopulmonary arrest should be treated first. Lightning acts like a massive defibrillation, causing temporary paralysis of the heart and respiratory centers. These victims have a good chance of resuscitation with immediate CPR, whereas those with vital signs are more likely to survive the initial event.

Question 3

A key difference between the adult START triage system and the pediatric JumpSTART system is the management of an apneic patient. What intervention is performed in the JumpSTART algorithm for an apneic child that is NOT performed for an adult?

Accepted Answer

Assessing for a peripheral pulse and, if present, delivering five rescue breaths.

Answer

The JumpSTART algorithm accounts for the fact that children are more likely to experience respiratory arrest before cardiac arrest. If an apneic child has a palpable pulse after the airway is opened, the rescuer should deliver five rescue breaths. If breathing resumes, the child is tagged RED (Immediate). This intervention is unique to the pediatric algorithm.

Question 4

You are the first nurse to arrive at a chaotic mass casualty incident. According to disaster management principles, what is your PRIMARY role during the initial response phase?

Accepted Answer

Perform rapid triage to sort patients and do the greatest good for the greatest number of people.

Answer

In a mass casualty incident, the primary goal shifts from doing everything possible for one patient to doing the greatest good for the greatest number of people. The first qualified provider on scene is responsible for rapidly triaging victims to identify who needs immediate transport and life-saving care, thereby maximizing survival for the entire group.

Question 5

Following a chemical spill at an industrial plant, numerous victims arrive at the hospital's emergency entrance via private vehicles. They are coughing and complaining of skin irritation. What is the absolute priority action the trauma nurse must ensure before these patients enter the treatment area?

Accepted Answer

Moving all patients to a designated decontamination zone for removal of clothing and showering.

Answer

The highest priority is to prevent the spread of contamination to healthcare providers, other patients, and the facility itself. All patients exposed to a chemical agent must undergo thorough decontamination *before* entering the main treatment area. This involves removing all clothing and washing with copious amounts of water.
