How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Identify the trauma assessment component that includes reassessment of interventions and trending vital signs.

Answer: Reassessment (ongoing assessment). Monitors patient status changes and intervention efficacy throughout transport and care.

Flashcard 2: Which kinematics concept explains that injury severity increases with greater energy transfer to tissues?

Answer: Kinetic energy transfer. Dictates that higher energy from speed or mass correlates with more severe tissue destruction.

Flashcard 3: What is the main injury pattern concern in rapid deceleration events (for example, high-speed MVC)?

Answer: Shearing injuries to organs and vessels. Results from differential deceleration rates between fixed and mobile structures, causing tears.

Flashcard 4: What is the formula for momentum used in trauma kinematics?

Answer: $p=mv$. Measures an object's tendency to continue motion, relevant for impact force in collisions.

Flashcard 5: What is the definition of penetrating trauma in terms of tissue damage mechanism?

Answer: Injury from an object entering the body. Causes localized tissue disruption along the path of the penetrating object, often from projectiles or stabs.

Flashcard 6: What is the correct order of priorities in the primary assessment for major trauma?

Answer: Airway, Breathing, Circulation, Disability, Exposure. Follows the ABCDE mnemonic to systematically address life-threatening issues in trauma patients.

Flashcard 7: What is the correct definition of the index of suspicion in trauma assessment?

Answer: Anticipated injuries based on MOI and findings. Guides paramedics to predict hidden injuries by integrating mechanism of injury with clinical observations.

Flashcard 8: Using $KE=\frac{1}{2}mv^2$, if speed doubles and mass is constant, by what factor does kinetic energy change?

Answer: Increases by a factor of $4$. Velocity's squared term in the formula means doubling speed quadruples kinetic energy.

Flashcard 9: What is the formula for kinetic energy used in trauma kinematics?

Answer: $KE=\frac{1}{2}mv^2$. Quantifies energy based on mass and velocity squared, critical for assessing injury potential.

Flashcard 10: Using $KE=\frac{1}{2}mv^2$, if mass doubles and speed is constant, by what factor does kinetic energy change?

Answer: Increases by a factor of $2$. Mass is linear in the formula, so doubling it directly doubles the kinetic energy.

Flashcard 11: What is the most concerning clinical implication of vehicle intrusion into the passenger compartment?

Answer: High likelihood of serious internal injury. Indicates significant energy transfer, correlating with higher rates of visceral and skeletal damage.

Flashcard 12: What is the definition of blunt trauma in terms of tissue damage mechanism?

Answer: Injury from impact without skin penetration. Involves force distribution over a wide area, leading to internal injuries without external wounds.

Flashcard 13: Identify the primary goal of the trauma assessment: what outcome is prioritized above all others?

Answer: Identify and treat immediate life threats rapidly. Prioritizes stabilizing critical conditions to prevent death, forming the core of trauma care protocols like ATLS.

Flashcard 14: What injury pattern is most associated with a rollover MVC regardless of restraint use?

Answer: Multisystem trauma with possible ejection. Involves unpredictable forces and directions, increasing risk of widespread injuries and ejection.

Flashcard 15: Which option best describes the most likely injury pattern in a lateral-impact MVC to the near-side occupant?

Answer: Head, chest, pelvis injuries on the impact side. Lateral forces compress structures on the impact side, leading to ipsilateral trauma patterns.

Flashcard 16: What finding indicates the need for immediate chest decompression in suspected tension pneumothorax?

Answer: Severe respiratory distress with signs of shock. Represents progression to tension pneumothorax, requiring urgent intervention to relieve intrathoracic pressure.

Flashcard 17: Identify the immediate intervention for life-threatening external extremity hemorrhage found in the primary assessment.

Answer: Apply a tourniquet proximal to the bleeding site. Stops massive bleeding effectively when direct pressure fails, adhering to hemorrhage control protocols.

Flashcard 18: What mechanism of injury term describes energy transfer to the body from an external force?

Answer: Kinematics. Focuses on the physics of motion and energy dissipation causing tissue damage in trauma scenarios.

Flashcard 19: Identify the most appropriate assessment approach when the trauma patient has altered mental status and unreliable history.

Answer: Perform a rapid head-to-toe exam immediately. Allows systematic identification of injuries when patient cannot provide reliable information.

Flashcard 20: What is the correct initial method to open the airway in an unresponsive trauma patient with possible spinal injury?

Answer: Manual jaw thrust with inline stabilization. Protects the cervical spine during airway management in trauma patients with suspected vertebral injury.

Flashcard 21: What is the first action in a trauma call when arriving at the scene before patient contact?

Answer: Scene size-up for hazards and safety. Ensures provider safety and identifies potential risks before approaching the patient, as per standard EMS protocols.

Flashcard 22: In a frontal MVC, what is the classic injury mechanism when the occupant strikes the steering wheel or dashboard?

Answer: Three collisions: vehicle, body, and organs. Describes sequential energy transfers: external impact, body against restraints, and internal organs.

Flashcard 23: Which option is the best immediate airway maneuver when C-spine injury is suspected?

Answer: Jaw-thrust maneuver. Maintains cervical spine alignment while opening the airway, minimizing risk of further spinal cord injury.

Flashcard 24: Which triage decision is indicated when the scene suggests high-energy MOI and potential occult injury?

Answer: Transport to an appropriate trauma center. Ensures specialized care for potentially severe, hidden injuries that may not be immediately apparent.
