Question

The nurse is triaging clients following a tornado. One of the clients is unable to follow commands, capillary refill is 3 seconds and has respirations of 31 breaths/minute. Using the Simple Triage and Rapid Treatment triage method, how should the nurse tag this client?

Answer 1

Correct Answers:

Red tag

Rationale :

🚨 Red tag means immediate priority because the client has life-threatening findings but is still potentially salvageable with rapid intervention.

🚨 In START triage, a respiratory rate greater than 30/min automatically places the client in the red/immediate category.

🚨 This client also has capillary refill of 3 seconds, which suggests poor perfusion because START uses capillary refill greater than 2 seconds as another red-tag finding.

🚨 Inability to follow commands also indicates altered mental status, which is an additional sign that urgent care is required.

🚨 The combination of RR 31/min, delayed capillary refill, and inability to follow commands makes this client unstable and in need of immediate treatment.

Incorrect Options:

🔹 Blue tag is not part of the standard START color categories commonly used in basic disaster triage. START usually uses red, yellow, green, and black to organize priority of care.

🔹 Green tag is used for clients with minor injuries who can walk and wait for care. This client cannot follow commands and has abnormal breathing and perfusion findings, so green is unsafe.

🔹 Black tag is used for clients who are deceased or expected to die despite available care, especially if they are not breathing after airway repositioning. This client is breathing, so the priority is immediate treatment rather than expectant/deceased classification.

Answer 2

Correct Answers:

The client is experiencing severe muscle spasms despite opioid therapy.

Rationale :

🕷️ Black widow spider venom is neurotoxic and can cause severe muscle cramping, rigidity, abdominal pain, hypertension, diaphoresis, nausea, and intense pain.

🕷️ Initial treatment usually includes wound care, pain control, muscle relaxants, and supportive management, but antivenin may be considered when symptoms are severe or uncontrolled.

🕷️ The key reason for administering antivenin is persistent, severe systemic toxicity such as severe muscle spasms despite opioid therapy.

🕷️ This finding shows that routine symptomatic treatment is not adequately controlling the venom’s neuromuscular effects.

🕷️ Antivenin helps neutralize circulating venom and can rapidly improve severe pain and muscle spasms when the client does not respond to standard therapy.

Incorrect Options:

🔹 Proteinuria and elevated creatinine kinase levels can suggest muscle injury or possible renal stress, but they are not the classic primary indication for black widow antivenin. The strongest indication is severe systemic neuromuscular symptoms that remain uncontrolled despite treatment.

🔹 Dangerously low blood pressure is not the typical severe manifestation of black widow envenomation. Black widow bites more commonly cause hypertension due to autonomic stimulation and severe pain.

🔹 Signs of infection at the bite site require wound care and possibly antibiotics if infection is confirmed. Antivenin does not treat infection; it neutralizes venom-related systemic effects.

Answer 3

Correct Answers:

27%

Rationale :

🔹 Entire chest and abdomen (anterior trunk) = 18%

Chest + abdomen together make up the entire anterior trunk.

🔹 Entire right arm = 9%

One full arm = 9% total body surface area.

Even though burn is partial-thickness, it still counts toward TBSA burned.

🔹 Add percentages:

18% + 9% = 27%

✅ Answer: 27%

❌ Incorrect Options

18%

🔹 This counts only the anterior trunk and leaves out the burned right arm.

🔹 It underestimates the total burn extent.

45%

🔹 This overestimates the injury and would include additional body regions not described.

🔹 Neither posterior trunk nor both arms are involved.

36%

🔹 This would be correct if both anterior and posterior trunk (18% +18%) were burned.

🔹 The question specifies only chest and abdomen (anterior trunk) plus one arm.

Answer 4

Correct Answers:

Red, dry skin

Rationale :

🌡️ Heat stroke is a life-threatening emergency characterized by failure of thermoregulation, causing the body temperature to rise dramatically, often above 40°C (104°F).

🌡️ A classic finding is red, hot, dry skin because sweating mechanisms may fail, leaving the skin dry despite dangerous hyperthermia.

🌡️ This differs from heat exhaustion, where sweating is usually still present. In heat stroke, loss of sweating combined with altered mental status and hyperthermia signals a medical emergency.

🌡️ The nurse should also monitor for tachycardia, hypotension, confusion, seizures, and organ dysfunction, as untreated heat stroke can progress rapidly.

🌡️ Recognizing red, dry skin supports prompt cooling interventions and prevention of neurologic injury.

Incorrect Options:

🔹 Nausea may occur with heat-related illness, especially heat exhaustion, but it is not the hallmark manifestation most associated with heat stroke. It is nonspecific compared with dry, hot skin.

🔹 Vertigo can occur with dehydration or heat exhaustion, but it is not the classic defining sign of heat stroke. The key concern is thermoregulatory failure.

🔹 Profuse sweating is more commonly associated with heat exhaustion, not classic heat stroke. In heat stroke, skin is typically dry due to failed sweating.

Answer 5

Correct Answers:

Place the client in a heated blanket and monitor temperature regularly

Rationale :

❄️ A client with hypothermia requires controlled rewarming to prevent worsening metabolic and cardiovascular instability.

❄️ Placing the client in a heated blanket provides external warming while allowing the nurse to monitor response and prevent overheating.

❄️ Rewarming reduces risks such as dysrhythmias, coagulopathy, acidosis, and impaired oxygen delivery, which can worsen if hypothermia persists.

❄️ Regular temperature monitoring is essential because rapid or poorly controlled warming can cause complications.

❄️ This intervention directly addresses the priority problem—ongoing heat loss.

Incorrect Options:

🔹 Continue aggressive fluid resuscitation while avoiding thermal interventions is incorrect because hypothermia itself must be treated. Avoiding warming allows further complications.

🔹 Cover the client with a cold, damp blanket would worsen heat loss and increase hypothermia. This is unsafe.

🔹 Administer fluids through a rapid infusion device to warm the client may sound helpful, but “rapid infusion” can be problematic and is not the best standalone intervention here. External warming with monitoring is the safer primary action.

Answer 6

Correct Answers:

Genitalia
Hands
Face

Rationale :

🩹 Genitalia

🩹 Burns involving the genitalia meet burn center referral criteria because of the risk for functional impairment, infection risk, and complex wound management.

🩹 These burns often affect sensitive tissue and may require specialized care, reconstructive support, and multidisciplinary treatment.

🩹 Even relatively small burns in this area can warrant referral because location alone makes them high risk.

✋ Hands

✋ Burns involving the hands require burn center referral because they can threaten fine motor function, mobility, and long-term independence.

✋ Hand burns carry a high risk of contractures and disability if not managed with specialized burn treatment and rehabilitation.

✋ Preserving function is a major reason these burns meet referral criteria even if total burn size is limited.

😷 Face

😷 Burns involving the face meet referral criteria because of risk for airway involvement, vision concerns, cosmetic injury, and functional impairment.

😷 Facial burns may be associated with inhalation injury, which requires specialized monitoring and management.

😷 Due to the complexity and consequences of facial burns, burn center care is indicated.

❌ Incorrect Options

Legs

🔹 Burns to the legs do not automatically meet referral criteria based on location alone. Referral depends more on burn depth, extent, or other complicating factors.

Arms

🔹 General burns to the arms are not automatic referral criteria unless they involve the hands, are extensive, or meet other severity criteria.

Trunk

🔹 Trunk burns alone are not automatic referral criteria based solely on location. Other factors such as TBSA burned or burn depth would matter.

Answer 7

Correct Answers:

Hemorrhage

Rationale :

🩸 Hemorrhage is the most common preventable cause of early trauma death within the first 48 hours.

🩸 Severe blood loss causes reduced circulating volume, poor tissue perfusion, cellular hypoxia, and shock.

🩸 If uncontrolled, hemorrhage rapidly leads to metabolic acidosis, coagulopathy, hypothermia, and cardiovascular collapse.

🩸 Early trauma care focuses on controlling bleeding, restoring circulation, and preventing shock progression.

🩸 This is why rapid assessment for internal and external bleeding is a priority in trauma clients.

Incorrect Options:

🔹 Infection is usually a later complication after trauma, especially with open wounds, burns, surgery, or prolonged hospitalization. It is not the most common cause of death in the first 48 hours.

🔹 Medication reaction can occur, but it is not the leading early cause of trauma death. Early trauma mortality is more strongly linked to airway compromise, brain injury, and hemorrhage.

🔹 MODS develops later as a complication of severe shock, sepsis, or prolonged inflammatory response. It is not typically the main cause of death in the first 48 hours.

Answer 9

Correct Answers:

FAST provides real-time imaging and can detect free fluid within 3 to 5 minutes.

Rationale :

🖥️ FAST is preferred in many trauma settings because it is rapid, noninvasive, and can identify free intraperitoneal fluid at the bedside.

🖥️ It provides real-time imaging, allowing the trauma team to quickly assess for bleeding without delaying urgent care.

🖥️ FAST is especially useful in unstable clients because it can be performed during resuscitation and repeated if the client’s condition changes.

🖥️ Detecting free fluid within minutes helps guide decisions about surgery, CT imaging, or continued monitoring.

🖥️ Compared with DPL, FAST avoids an invasive abdominal procedure and reduces procedure-related risks.

Incorrect Options:

🔹 DPL is more accurate in diagnosing internal bleeding in trauma clients may be true in some situations because DPL is highly sensitive, but it is not the advantage of FAST over DPL. The question asks why FAST is beneficial compared with DPL.

🔹 FAST can detect bony fractures associated with abdominal trauma is incorrect because FAST evaluates free fluid, not fractures. X-ray or CT is used to assess bones.

🔹 DPL involves less client risk compared to FAST due to the need for anesthesia is incorrect because DPL is invasive and carries risks such as organ injury, bleeding, or infection. FAST is noninvasive and does not require anesthesia.

Answer 10

Correct Answers:

"Effects of radiation can include skin reddening and later development of cancer."

Rationale :

☢️ Radiation exposure can cause both acute effects and delayed effects, depending on the dose, duration, and type of exposure.

☢️ Skin reddening can occur after significant exposure because rapidly dividing skin cells are sensitive to radiation injury.

☢️ Radiation can also damage DNA, which may increase the long-term risk for cancer.

☢️ Symptoms do not always occur immediately, and low-level exposure may not cause obvious early manifestations.

☢️ This statement correctly recognizes both short-term tissue effects and delayed health risks.

Incorrect Options:

🔹 “The skin is the only organ that is affected by radiation exposure.” Radiation can affect multiple organs, especially rapidly dividing cells such as bone marrow, gastrointestinal lining, and reproductive tissue. The skin is not the only affected organ.

🔹 “Exposure to radiation results in death within days, regardless of the amount of exposure.” The outcome depends on the radiation dose and exposure time. Low or moderate exposure does not always cause death.

🔹 “Radiation exposure always causes immediate, severe symptoms.” Radiation effects can be delayed, mild, severe, or absent initially. Immediate severe symptoms usually occur only with high-dose exposure.
