Question 1Fundamentals and Core Concepts (unverified placeholder)

Before beginning care for a patient at any scene, what should a responder confirm first?

  1. Scene safety Correct answer.
  2. The nearest hospital's bed availability
  3. The patient's insurance coverage and billing details
  4. The patient's current pain score and full medical history

Explanation

Care begins only after the responder confirms the scene is safe from hazards such as traffic, fire, unstable structures, or violence. Patient-specific information is gathered later, during the assessment.

Question 2Fundamentals and Core Concepts (unverified placeholder)

Which action is the single most effective way to prevent transmission of infection from one patient to another?

  1. Hand hygiene Correct answer.
  2. Disinfecting equipment after each shift
  3. Changing gloves between tasks with the same patient
  4. Wearing a gown for every patient contact

Explanation

Hand hygiene performed before and after patient contact removes transient organisms and is the cornerstone of infection prevention. Gloves are an adjunct and never a substitute for hand hygiene.

Question 3Fundamentals and Core Concepts (unverified placeholder)

Which value falls within the normal resting respiratory rate for a healthy adult?

  1. 12 to 20 breaths per minute Correct answer.
  2. 24 to 30 breaths per minute
  3. More than 40 breaths per minute in a resting adult
  4. 4 to 8 breaths per minute

Explanation

A healthy adult at rest breathes about 12 to 20 times per minute. Rates below about 10 or above about 24 in a resting adult are abnormal and warrant further assessment.

Question 4Fundamentals and Core Concepts (unverified placeholder)

What must a competent adult patient provide before an elective procedure may be performed?

  1. A completed insurance authorization form
  2. Informed consent Correct answer.
  3. A verbal promise to pay for the procedure
  4. A referral from another clinician

Explanation

Competent adults must give voluntary informed consent after receiving information about the nature of the procedure, its risks, benefits, and alternatives. Administrative or financial steps do not substitute for consent.

Question 5Fundamentals and Core Concepts (unverified placeholder)

Which method is the first-line control for severe external bleeding from an extremity?

  1. Immediately applying a tourniquet to every bleeding wound
  2. Elevating the limb above the heart without pressure
  3. Irrigating the wound with large volumes of saline
  4. Direct pressure Correct answer.

Explanation

Firm direct pressure applied to the bleeding point controls most external hemorrhage and is the first step. Tourniquets are reserved for limb bleeding that is not controlled by pressure or that is immediately life-threatening.

Question 6Fundamentals and Core Concepts (unverified placeholder)

At what point should the care provided to a patient be documented?

  1. At the time the care is given Correct answer.
  2. At the end of the clinician's shift, from memory
  3. Only if the patient is later admitted to hospital
  4. Only when the patient requests a written summary

Explanation

Documentation should be contemporaneous, recorded at or immediately after the time care is provided. Delayed charting based on memory is more likely to be incomplete or inaccurate.

Question 7Fundamentals and Core Concepts (unverified placeholder)

Which technique best confirms that a patient understood discharge instructions?

  1. Giving the patient a printed leaflet at discharge
  2. Asking the patient to sign that teaching occurred
  3. Asking the patient to explain the instructions back Correct answer.
  4. Speaking more loudly and repeating the same words

Explanation

Teach-back confirms understanding by having the patient restate the plan in their own words. A signature or a handout documents that information was offered, not that it was comprehended.

Question 8Fundamentals and Core Concepts (unverified placeholder)

Which range represents a normal resting heart rate for a healthy adult?

  1. 60 to 100 beats per minute Correct answer.
  2. 20 to 40 beats per minute
  3. 40 to 55 beats per minute
  4. 110 to 140 beats per minute

Explanation

A normal adult resting heart rate is approximately 60 to 100 beats per minute. Rates outside this range may be physiologic for some individuals but require evaluation in the acute setting.

Question 9Fundamentals and Core Concepts (unverified placeholder)

A patient with a suspected pelvic fracture is pale, cool, and tachycardic after a fall. Which type of shock is most likely?

  1. Anaphylactic shock triggered by a bee sting
  2. Cardiogenic shock from acute heart failure
  3. Septic shock from a chronic wound infection
  4. Hemorrhagic shock Correct answer.

Explanation

Pelvic fracture can cause major blood loss into the retroperitoneum, producing hypovolemic (hemorrhagic) shock with pale, cool skin and tachycardia. The mechanism is loss of circulating volume rather than an allergic, infectious, or pump failure.

Question 10Fundamentals and Core Concepts (unverified placeholder)

Which airway maneuver is preferred for an unresponsive trauma patient with a suspected cervical spine injury?

  1. Placing the patient face down so gravity clears the airway
  2. Hyperextending the neck over a folded blanket
  3. Head-tilt chin-lift with the neck fully extended
  4. Jaw thrust Correct answer.

Explanation

The jaw thrust displaces the mandible forward and opens the airway without extending the cervical spine, so it is preferred when spinal injury is suspected. Neck extension maneuvers risk further displacement of an unstable spine.

Question 11Fundamentals and Core Concepts (unverified placeholder)

What is the priority action when managing an open abdominal wound with protruding bowel?

  1. Irrigating the exposed bowel with tap water before transport
  2. Pushing the bowel back into the abdomen to keep it warm
  3. Packing the wound tightly with dry gauze
  4. Covering the wound with a moist sterile dressing Correct answer.

Explanation

Eviscerated bowel is covered with a moist sterile dressing and an occlusive layer to prevent drying and contamination. The bowel is never pushed back into the abdomen, and the patient is transported urgently.

Question 12Fundamentals and Core Concepts (unverified placeholder)

Which practice most directly reduces medication administration errors?

  1. Preparing several patients' medications at one time
  2. Leaving doses at the bedside for the patient to take later
  3. Checking the rights of administration before giving Correct answer.
  4. Relying on memory of the previous shift's medication list

Explanation

Verifying the right patient, drug, dose, route, and time immediately before administration catches most errors before they reach the patient. Memory and multi-patient preparation increase the chance of a slip.

Question 13Fundamentals and Core Concepts (unverified placeholder)

Using the rule of nines in an adult, which body area represents approximately 18% of total body surface area?

  1. One entire arm
  2. The head and neck
  3. The anterior trunk plus the head
  4. One entire leg Correct answer.

Explanation

In the adult rule of nines each entire leg, including the foot, is about 18%, each arm is about 9%, and the head and neck about 9%. The anterior trunk is 18% on its own, so adding the head overstates the area.

Question 14Fundamentals and Core Concepts (unverified placeholder)

Why is a suspected long-bone fracture splinted before transport?

  1. To force the bone ends back into their normal alignment before moving
  2. To convert an open fracture into a closed one
  3. To reduce pain and prevent further tissue injury Correct answer.
  4. To make imaging at the hospital unnecessary

Explanation

Splinting stabilizes fracture fragments, which decreases pain and limits additional damage to muscle, nerve, and blood vessels during movement. It does not replace definitive evaluation or imaging.

Question 15Fundamentals and Core Concepts (unverified placeholder)

Which device is used to hold the tongue away from the posterior pharynx in an unresponsive patient who has no gag reflex?

  1. Manual suction catheter
  2. Nasal cannula
  3. Oropharyngeal airway Correct answer.
  4. Non-rebreather mask

Explanation

An oropharyngeal airway is inserted in a patient without a gag reflex to keep the tongue from obstructing the pharynx. Oxygen delivery devices and suction catheters do not maintain airway patency.

Question 16Fundamentals and Core Concepts (unverified placeholder)

What compression-to-ventilation ratio is recommended for one-rescuer adult cardiopulmonary resuscitation?

  1. 30:2 Correct answer.
  2. 10:2
  3. 5:1
  4. 15:2

Explanation

Single-rescuer adult CPR uses 30 compressions followed by 2 breaths, which minimizes interruptions in chest compressions. A 15:2 ratio is used for two-rescuer infant and child resuscitation.

Question 17Fundamentals and Core Concepts (unverified placeholder)

A trauma patient is shivering with cool, wet skin after a prolonged extrication in the rain. Which action is most appropriate?

  1. Remove wet clothing and apply warm blankets Correct answer.
  2. Rub the limbs vigorously to generate heat
  3. Delay transport until the shivering stops
  4. Give hot oral fluids immediately to rewarm the patient

Explanation

Passive rewarming - removing wet clothing, insulating the patient, and warming the vehicle or compartment - limits further heat loss and is started immediately. Shivering alone does not justify delaying transport for a trauma patient.

Question 18Fundamentals and Core Concepts (unverified placeholder)

Which finding supports the use of spinal motion restriction after blunt trauma?

  1. Complaints of mild thirst with stable vital signs
  2. An isolated ankle sprain with normal gait
  3. A superficial abrasion on the forearm
  4. Midline tenderness of the neck Correct answer.

Explanation

Midline neck or back tenderness, a neurologic deficit, altered mental status, intoxication, or a distracting injury are criteria that support spinal motion restriction. Isolated minor distal injuries do not.

Question 19Fundamentals and Core Concepts (unverified placeholder)

A patient in severe respiratory distress is hypoxic. Which initial oxygen delivery is most appropriate?

  1. Room air with coaching in pursed-lip breathing
  2. Nasal cannula at 1 L/min
  3. Intermittent oxygen only if saturation falls below 80%
  4. High-concentration oxygen by non-rebreather mask Correct answer.

Explanation

Severe distress with hypoxia calls for the highest oxygen concentration available, which a non-rebreather mask provides. Low-flow devices are inadequate when demand is high.

Question 20Fundamentals and Core Concepts (unverified placeholder)

Which handover format structures information as Situation, Background, Assessment, and Recommendation?

  1. START
  2. MARCH
  3. SBAR Correct answer.
  4. SOAP

Explanation

SBAR organizes a handover into Situation, Background, Assessment, and Recommendation, giving a predictable sequence for communicating risk. SOAP structures clinical notes, while MARCH and START are treatment and triage frameworks.

Question 21Fundamentals and Core Concepts (unverified placeholder)

A patient with a tension pneumothorax develops hypotension. Which mechanism best explains the shock?

  1. Direct injury to the heart muscle reducing contractility
  2. Loss of blood volume into the pleural space from the torn lung
  3. Massive vasodilation caused by circulating bacterial toxins
  4. Obstructed venous return to the heart Correct answer.

Explanation

Rising intrathoracic pressure in tension pneumothorax compresses the great veins and impairs venous return, so cardiac output falls despite adequate circulating volume. This is obstructive shock and is relieved by decompression.

Question 22Fundamentals and Core Concepts (unverified placeholder)

Why can large-volume crystalloid resuscitation worsen outcomes in uncontrolled hemorrhage?

  1. It permanently destroys the patient's ability to form any new clot in the future
  2. It increases hemoglobin concentration and thickens the blood
  3. It dilutes clotting factors and can dislodge existing clot Correct answer.
  4. It causes immediate hemolysis of the patient's red blood cells

Explanation

Crystalloids dilute coagulation factors, lower temperature, and raise blood pressure, all of which can disrupt a formed clot and renew bleeding. Damage-control resuscitation therefore limits crystalloid and favors blood products.

Question 23Fundamentals and Core Concepts (unverified placeholder)

In the START mass-casualty triage system, which patient is assigned to the immediate (red) category?

  1. A patient who is awake, follows commands, and has only minor injuries
  2. A patient whose respiratory rate is 34 per minute Correct answer.
  3. A patient with no spontaneous breathing after the airway is opened
  4. A walking patient with a minor laceration

Explanation

In START, respirations above 30 per minute, absent radial pulse or capillary refill over 2 seconds, or inability to follow commands place a patient in the immediate category. Absent breathing after the airway is opened is categorized as deceased.

Question 24Fundamentals and Core Concepts (unverified placeholder)

For a question about whether a treatment improves patient outcomes, which source provides the strongest evidence?

  1. An uncontrolled case series from one hospital
  2. A textbook chapter written by a recognized expert
  3. A systematic review of randomized trials Correct answer.
  4. A single case report from an experienced clinician

Explanation

Well-conducted systematic reviews and meta-analyses of randomized trials sit at the top of the evidence hierarchy for therapeutic questions because they pool randomized comparisons and reduce random error.

Question 25Fundamentals and Core Concepts (unverified placeholder)

Which finding is the earliest sign of compensated hemorrhagic shock in a previously healthy young adult?

  1. A fall in systolic blood pressure below 90 mmHg
  2. Widening pulse pressure with bradycardia
  3. Absent peripheral pulses and unresponsiveness
  4. Rising heart rate with narrowing pulse pressure Correct answer.

Explanation

Baroreceptor-mediated tachycardia and increased peripheral resistance maintain blood pressure early, so a rising heart rate with a narrowing pulse pressure precedes measurable hypotension. frank hypotension indicates decompensation.

Question 26Fundamentals and Core Concepts (unverified placeholder)

During the primary survey of a trauma patient, which action is performed first?

  1. Assess the airway while protecting the cervical spine Correct answer.
  2. Expose the patient to check for hidden injuries
  3. Measure the blood pressure in both arms
  4. Obtain a complete medical history

Explanation

The primary survey follows an ABCDE sequence, so airway patency with cervical spine protection precedes breathing, circulation, disability, and exposure. History-taking and bilateral blood pressure measurements belong to later assessment.

Question 27Fundamentals and Core Concepts (unverified placeholder)

In the AMPLE trauma history, what does the letter "L" represent?

  1. Lung sounds
  2. Lactate level
  3. Level of consciousness
  4. Last meal Correct answer.

Explanation

AMPLE stands for Allergies, Medications, Past medical history, Last meal, and Events surrounding the injury. The last meal is relevant for anesthesia planning and aspiration risk.

Question 28Fundamentals and Core Concepts (unverified placeholder)

Which physical finding is the hallmark of a flail chest?

  1. Subcutaneous emphysema around the clavicle
  2. Absent breath sounds over the injured side
  3. Tracheal deviation toward the injured side
  4. Paradoxical movement of the injured chest wall Correct answer.

Explanation

Flail chest occurs when multiple adjacent ribs are fractured in two or more places, creating a segment that moves opposite to the rest of the chest during breathing. This paradoxical motion is the defining sign.

Question 29Fundamentals and Core Concepts (unverified placeholder)

The Glasgow Coma Scale is used to assess which three areas?

  1. Eye opening, verbal response, and motor response Correct answer.
  2. Pupils, reflexes, and sensation
  3. Orientation, memory, and judgment
  4. Pulse, respirations, and blood pressure

Explanation

The Glasgow Coma Scale sums scores for eye opening, verbal response, and motor response. The total ranges from 3 to 15 and helps quantify level of consciousness.

Question 30Fundamentals and Core Concepts (unverified placeholder)

A trauma patient has life-threatening bleeding from an extremity that is not controlled by direct pressure. Which action is most appropriate next?

  1. Apply a tourniquet proximal to the bleeding site Correct answer.
  2. Irrigate the wound with saline
  3. Apply ice packs around the wound
  4. Elevate the limb above the heart

Explanation

A tourniquet is indicated for severe extremity hemorrhage that does not respond to direct pressure. It is placed proximal to the wound to occlude arterial inflow.

Question 31Fundamentals and Core Concepts (unverified placeholder)

An unconscious trauma patient requires emergency surgery, and no family member is available to give consent. Which type of consent applies?

  1. Parental consent
  2. Expressed consent
  3. Implied consent Correct answer.
  4. Informed consent

Explanation

Implied consent, often under the emergency doctrine, allows treatment when a patient cannot consent and delay would risk serious harm. It applies to life-threatening emergencies.

Question 32Fundamentals and Core Concepts (unverified placeholder)

Which piece of personal protective equipment is essential before direct contact with a trauma patient's blood or body fluids?

  1. Surgical mask
  2. Shoe covers
  3. Gloves Correct answer.
  4. Sterile gown

Explanation

Standard precautions require gloves for contact with blood, body fluids, mucous membranes, and nonintact skin. Additional equipment is added based on anticipated exposure risk.

Question 33Fundamentals and Core Concepts (unverified placeholder)

Which finding suggests an inhalation injury to the airway?

  1. Pink, warm skin
  2. Singed nasal hairs and soot in the mouth Correct answer.
  3. Clear breath sounds bilaterally
  4. Heart rate of 60 beats/min

Explanation

Singed nasal hairs, soot in the mouth or sputum, and hoarseness suggest heat or chemical injury to the airway. These findings warrant early airway evaluation because edema can progress rapidly.

Question 34Fundamentals and Core Concepts (unverified placeholder)

A trauma patient with a suspected basilar skull fracture requires an airway adjunct. Which device should be avoided?

  1. Oropharyngeal airway
  2. Endotracheal tube
  3. Nasopharyngeal airway Correct answer.
  4. Supraglottic airway

Explanation

A nasopharyngeal airway is avoided when basilar skull fracture is suspected because it may be inadvertently inserted into the cranial vault. Oropharyngeal and advanced airways do not carry that specific risk.

Question 35Fundamentals and Core Concepts (unverified placeholder)

A patient has an open pneumothorax with a sucking chest wound. Which dressing is appropriate while awaiting a chest tube?

  1. A fully occlusive dressing sealed on all four sides
  2. A three-sided occlusive dressing Correct answer.
  3. A transparent adhesive film sealed on all four sides
  4. A dry sterile gauze left open to air

Explanation

A three-sided occlusive dressing allows air to escape during expiration while limiting air entry during inspiration. This reduces the risk of converting an open pneumothorax into a tension pneumothorax.

Question 36Fundamentals and Core Concepts (unverified placeholder)

A patient with a cervical spinal cord injury has hypotension and bradycardia with warm, dry skin. Which type of shock does this most suggest?

  1. Septic shock
  2. Cardiogenic shock
  3. Neurogenic shock Correct answer.
  4. Hypovolemic shock

Explanation

Neurogenic shock results from loss of sympathetic tone after a spinal cord injury, producing vasodilation, hypotension, and bradycardia. Warm, dry skin reflects peripheral vasodilation rather than the cool, clammy skin of hypovolemia.

Question 37Fundamentals and Core Concepts (unverified placeholder)

Which finding is the earliest and most reliable indicator of compartment syndrome in an injured extremity?

  1. Paralysis of the fingers or toes
  2. Pain that worsens with passive stretch Correct answer.
  3. Pallor of the skin
  4. Absent distal pulse

Explanation

Compartment syndrome initially causes pain out of proportion to the injury and pain with passive stretch of the affected muscles. Pulselessness and paralysis are late findings and should not be awaited.

Question 38Fundamentals and Core Concepts (unverified placeholder)

A trauma patient who is 24 weeks pregnant is supine and becomes hypotensive. Which action is most appropriate?

  1. Tilt the patient to the left lateral position Correct answer.
  2. Apply abdominal compression
  3. Elevate both legs to 90 degrees
  4. Place the patient in Trendelenburg position

Explanation

After 20 weeks of gestation, the gravid uterus can compress the inferior vena cava when the patient is supine. Left lateral tilt or manual uterine displacement improves venous return and cardiac output.

Question 39Fundamentals and Core Concepts (unverified placeholder)

Which factor most increases a geriatric patient's risk of serious injury after a low-energy fall?

  1. Resting bradycardia
  2. Increased muscle mass
  3. Use of anticoagulant medication Correct answer.
  4. Chronic hypertension

Explanation

Anticoagulant use increases the risk of intracranial hemorrhage and significant bleeding even after low-energy trauma. Geriatric patients also have reduced physiologic reserve and comorbid conditions.

Question 40Fundamentals and Core Concepts (unverified placeholder)

Which statement best describes permissive hypotension during resuscitation of uncontrolled hemorrhage?

  1. It requires large-volume crystalloid boluses before hemorrhage control
  2. It limits fluid administration to maintain perfusion without excessively raising blood pressure Correct answer.
  3. It is the preferred strategy for patients with severe traumatic brain injury
  4. It targets a mean arterial pressure above 90 mm Hg at all times

Explanation

Permissive hypotension limits fluid resuscitation until hemorrhage is controlled, aiming to maintain adequate perfusion without disrupting clot formation. It is not appropriate for patients with severe traumatic brain injury, who require adequate cerebral perfusion pressure.

Question 41Fundamentals and Core Concepts (unverified placeholder)

In a massive transfusion protocol, which ratio of packed red blood cells to fresh frozen plasma to platelets best approximates whole blood?

  1. 1:1:1 Correct answer.
  2. 4:1:1
  3. 2:1:2
  4. 1:2:1

Explanation

A balanced 1:1:1 ratio of packed red blood cells, fresh frozen plasma, and platelets approximates whole blood and reduces dilutional coagulopathy. It is commonly used in massive transfusion protocols for hemorrhagic shock.

Question 42Fundamentals and Core Concepts (unverified placeholder)

Which injury is characteristic of the primary phase of a blast injury?

  1. Blunt injury from being thrown by the blast wind
  2. Burn injury from a secondary fire
  3. Penetrating injury from flying debris
  4. Blast wave barotrauma to the lungs and ears Correct answer.

Explanation

The primary blast phase is caused by the overpressure wave and typically produces barotrauma to gas-containing organs such as the lungs, ears, and bowel. Debris, displacement, and burns occur in later phases.

Question 43Fundamentals and Core Concepts (unverified placeholder)

A patient with a crush injury has dark urine. Which urinalysis finding best supports rhabdomyolysis?

  1. Positive glucose with ketones
  2. Positive blood on dipstick without red blood cells on microscopy Correct answer.
  3. Low specific gravity with clear urine
  4. Positive leukocyte esterase with nitrites

Explanation

Myoglobin from muscle breakdown cross-reacts with the heme dipstick, producing a positive blood result even when microscopy shows no red blood cells. This pattern supports rhabdomyolysis.

Question 44Fundamentals and Core Concepts (unverified placeholder)

A trauma patient's family arrives while resuscitation is in progress. Which action is most appropriate?

  1. Have the family sign surgical consent immediately
  2. Ask security to remove the family from the department
  3. Assign a staff member to support the family and offer presence if policy permits Correct answer.
  4. Ignore the family until resuscitation is complete

Explanation

Family presence during resuscitation is supported when institutional policy allows and a staff member can support the family. The family should not be ignored or forcibly removed without assessment of the situation.

Question 45Fundamentals and Core Concepts (unverified placeholder)

Which set of findings represents Cushing triad in a patient with rising intracranial pressure?

  1. Hypertension, tachycardia, and regular respirations
  2. Hypotension, bradycardia, and hypothermia
  3. Hypotension, tachycardia, and tachypnea
  4. Hypertension, bradycardia, and irregular respirations Correct answer.

Explanation

Cushing triad consists of hypertension, bradycardia, and irregular respirations and indicates increased intracranial pressure with brainstem compression. It is a late and ominous sign.

Question 46Fundamentals and Core Concepts (unverified placeholder)

Which action best helps prevent secondary brain injury in a patient with severe traumatic brain injury?

  1. Maintaining adequate systolic blood pressure and oxygenation Correct answer.
  2. Hyperventilating to a PaCO2 of 25 mm Hg
  3. Restricting supplemental oxygen to avoid hyperoxia
  4. Administering hypotonic intravenous fluids

Explanation

Secondary brain injury is minimized by avoiding hypotension and hypoxemia, which reduce cerebral perfusion and oxygen delivery. Maintaining adequate systolic blood pressure and oxygenation is a core priority.

Question 47Fundamentals and Core Concepts (unverified placeholder)

Which laboratory marker best reflects the severity of inadequate tissue perfusion in hemorrhagic shock?

  1. Base deficit Correct answer.
  2. Platelet count
  3. Serum sodium
  4. Serum amylase

Explanation

Base deficit reflects the degree of metabolic acidosis caused by anaerobic metabolism during hypoperfusion. An increasing base deficit correlates with more severe shock and worse outcomes.

Question 48Fundamentals and Core Concepts (unverified placeholder)

Which medication class should be avoided in a trauma patient with active hemorrhage because it can impair platelet function?

  1. Nonsteroidal anti-inflammatory drugs Correct answer.
  2. Acetaminophen
  3. Antiemetics
  4. Opioid analgesics

Explanation

Nonsteroidal anti-inflammatory drugs inhibit cyclooxygenase and can impair platelet aggregation, increasing bleeding risk. They are generally avoided in patients with active hemorrhage.

Question 49Fundamentals and Core Concepts (unverified placeholder)

A restrained driver in a motor vehicle crash has a linear bruise across the lower abdomen. Which interpretation is most appropriate?

  1. It indicates a high-energy mechanism and possible hollow viscus injury Correct answer.
  2. It suggests only superficial skin injury
  3. It is unrelated to the crash mechanism
  4. It is a minor finding that does not require further evaluation

Explanation

A seat belt sign across the abdomen indicates that significant force was applied to the abdominal wall. It raises concern for hollow viscus or mesenteric injury and warrants further evaluation.

Question 50Fundamentals and Core Concepts (unverified placeholder)

Which statement about the "golden hour" of trauma care is most accurate?

  1. It applies only to burn injuries
  2. It emphasizes rapid assessment and definitive care to reduce mortality, rather than a strict 60-minute deadline Correct answer.
  3. It means stabilization should be delayed until all diagnostic tests are complete
  4. It is a legally mandated limit of 60 minutes from injury to surgery

Explanation

The golden hour is a concept emphasizing that early recognition, resuscitation, and definitive care improve trauma outcomes. It is not a rigid legal deadline, and delays for nonessential testing can be harmful.
