Questions
QUESTION 1 OF 69
As a surface rewarming measure for a client who is hypothermic, which is the highest
temperature up to which the fluid can be heated for peritoneal lavage?
Correct Answer: 113F
Rationale: Peritoneal lavage for rewarming hypothermic patients requires careful temperature control to prevent
further injury. The fluid used for peritoneal lavage should be heated to a maximum of 113°F (45°C) to effectively raise
core body temperature without causing thermal damage to the peritoneum. This temperature aligns with established
guidelines for internal rewarming techniques in hypothermia management. This aligns with 113F.
QUESTION 2 OF 69
Which functional level of trauma center is involved in providing a full continuum of
trauma services?
Correct Answer: Level 1
Rationale: Level 1 trauma centers are designated to provide the highest level of trauma care, offering a full spectrum
of preventive, resuscitative, operative, and postoperative services. This includes comprehensive care from initial injury
through rehabilitation, fulfilling the definition of a "full continuum of trauma services." Therefore, Level 1 is the correct
functional level for this care.

, QUESTION 3 OF 69
When the triage nurse assigns a green tag to a client during triage after a mass casualty
event, which statement is true about the client's injuries?
Correct Answer: The client has minor injuries that do not require immediate treatment.
Rationale: The client has minor injuries that do not require immediate treatment., a green tag signifies minimal
injuries that are not life-threatening and can be treated later, allowing immediate resources to be directed to more
critical patients. These individuals are often referred to as "walking wounded" and can wait for extended periods
without their condition worsening. Therefore, a green tag accurately reflects minor injuries not requiring immediate
intervention.
QUESTION 4 OF 69
Which triage class client would the nurse plan to treat first according to the disaster
triage tag system?
Correct Answer: Class I
Rationale: In disaster triage, Class I represents immediate or emergent conditions that require immediate life-saving
intervention. These clients have life-threatening injuries but a high likelihood of survival if treated promptly.
Therefore, the nurse prioritizes treating Class I clients first to maximize survival rates in a mass casualty event.
QUESTION 5 OF 69
Which color tag will be given by the triage nurse to a client assigned to class IV during a
mass casualty situation?
Correct Answer: Black
Rationale: In disaster triage, the black tag signifies the expectant or deceased category, representing individuals
with unsurvivable injuries or those who are already deceased. A client assigned to class IV in mass casualty incident
(MCI) triage is considered to have minimal chance of survival, even with immediate medical attention, or is beyond
help. Therefore, the triage nurse will assign a black tag to this client.
QUESTION 6 OF 69
Which statement is true about the disaster triage tag system?
Correct Answer: Clients with airway obstruction, who require immediate attention, are given a red tag.
Rationale: Clients with airway obstruction, who require immediate attention, are given a red tag., the START
(Simple Triage and Rapid Treatment) system uses color-coded tags to prioritize care based on survivability and
immediate need. A red tag signifies an immediate threat to life, such as airway obstruction or severe hemorrhage,
indicating the patient requires the most urgent intervention. Therefore, clients with airway obstruction, representing a
critical and life-threatening condition, are correctly assigned a red tag.
