How to Master One of the Hardest Parts of the IBSC TP-C Exam: Tactical Casualty Care (TECC/TCCC)

Ask IBSC TP-C candidates which questions slowed them down, and many will point to tactical casualty care. The medicine isn’t new, but tactical care often reverses the habits you built on the street.

On the TP-C, the right answer depends on the threat level, the phase of care, the evacuation time, and what you’re actually carrying. A treatment that’s correct in the back of an ambulance can be wrong under fire. Guidelines for tranexamic acid (TXA), blood products, fluids, and pain control have also changed in recent years, so an answer you learned a few years ago may be out of date.

We’ll walk you through the core concepts, traps, and a study plan.

Where Does Tactical Casualty Care Fit on the TP-C Exam?

Tactical Casualty Care (TECC/TCCC) is Domain I of IBSC’s TP-C Detailed Content Outline. It accounts for 55 of the 125 scored questions (44%), making it the largest domain by far. The outline divides it into 10 subtopics:

A. Methodology: Care in each of the three phases of care.
B. Hemostasis: High-risk wound recognition, reassessment, and bleeding control techniques.
C. Airway: Basic maneuvers through SGAs, cricothyroidotomy, intubation, RSI, and tube confirmation.
D. Respiration/Breathing: Capnography, pulse oximetry, chest seals, needle and tube thoracostomy, and burping a chest wound.
E. Circulation: Perfusion, causes of shock, damage control resuscitation, and oral fluids.
F. Vascular Access: Peripheral IV and intraosseous (IO) access.
G. Medication Administration: Oxygen, analgesia and sedation, over-the-counter drugs, and expanded-scope prescriptions.
H. Casualty Immobilization and Packaging: Neuro assessment, spinal injury, head injury, seizures, orthopedic injuries, dislocations, and burns.
I. Trauma Management: Triage, preventable causes of death, MARCH, mechanisms of injury, and thoracic and abdominal trauma.
J. Mass Casualty Triage: START and SALT.

That breadth is part of what makes the domain hard: you’re studying the whole casualty from point of injury to handoff.

Core Concepts You Need to Know

Phases of Care Drive Every Decision

Direct Threat / Care Under Fire / Hot Zone: Suppress the threat or move to safety first. The only medical intervention is controlling life-threatening extremity bleeding, usually with a limb tourniquet placed “high and tight.” Have the casualty self-apply it if they can.
Indirect Threat / Tactical Field Care / Warm Zone: Now you work through MARCH. Reassess every tourniquet, expose wounds, pack junctional bleeding, and address airway, respiration, and circulation.
Evacuation / Tactical Evacuation Care / Cold Zone: Continue and expand care with more equipment and personnel, including advanced airways, blood products, and monitoring.

MARCH and the Top Three Preventable Deaths

The outline asks you to use the MARCH algorithm: massive bleeding, airway, respiration, circulation, and hypothermia/head injuries. It also asks you to identify the top three causes of preventable death in tactical trauma. Classically, those are extremity hemorrhage, tension pneumothorax, and airway obstruction. MARCH puts them in that order, which is why bleeding comes before the airway.

Hemostasis Details That Get Tested

Tourniquet effectiveness: A tourniquet works when the bleeding stops and the distal pulse is gone. If it isn’t working, tighten it or add a second tourniquet just above the first.
Reassessment: In Tactical Field Care, replace a hasty high-and-tight tourniquet with a deliberate one 2 to 3 inches above the wound, and recheck every tourniquet and dressing after each casualty move.
Conversion: Current TCCC guidance calls for assessing tourniquets for conversion when evacuation is delayed, ideally within 2 hours. Don’t convert if the casualty is in shock, if you can’t closely monitor the wound, or if the limb is amputated.
Hemostatic agents and packing: Pack the wound tightly to the source of bleeding and hold firm direct pressure for at least 3 minutes. Combat Gauze is the TCCC first-choice dressing.
Junctional hemorrhage: Groin, axilla, and neck wounds can’t take a limb tourniquet. Use packing with pressure and a junctional tourniquet if available.

Airway and Breathing

For an unconscious casualty without obstruction, use a chin-lift or jaw-thrust, an NPA, and the recovery position. Let a conscious casualty with facial trauma sit up and lean forward. If basic measures fail and the airway is obstructed, a surgical cricothyroidotomy is the classic TCCC answer in the field. Intubation, RSI, and SGAs fit evacuation care better, and capnography is the most reliable way to confirm placement.

For breathing, cover open chest wounds with a vented or non-vented occlusive chest seal. If the casualty develops signs of tension pneumothorax, such as worsening respiratory distress, falling SpO2, or shock, burp the seal or briefly remove it. If that fails, perform needle decompression.

Circulation, Damage Control Resuscitation, and Access

TCCC uses altered mental status without a head injury and a weak or absent radial pulse as field signs of hemorrhagic shock. Damage control resuscitation (DCR) means stopping the bleeding, restoring perfusion without chasing a normal blood pressure, and preventing the “lethal triad” of hypothermia, acidosis, and coagulopathy.

Blood products: Current TCCC prefers whole blood, then plasma, red cells, and platelets in a 1:1:1 ratio, then plasma and red cells 1:1, then plasma or red cells alone.
Crystalloids and colloids: The 2016 outline lists both, but large crystalloid volumes dilute clotting factors and worsen acidosis. Current TCCC recommendations have dropped colloids such as Hextend.
TXA: 2 g by slow IV or IO push as soon as possible for casualties in or at risk of hemorrhagic shock, and no later than 3 hours after injury.
Calcium: 1 g IV or IO with or after the first unit of blood product.
Targets: Resuscitate to a palpable radial pulse and improved mentation. With suspected TBI, target a normal radial pulse and, if measurable, a systolic blood pressure of 100 to 110 mmHg.
Access and oral fluids: Use a peripheral IV when possible and IO when IV access fails or isn’t practical. A conscious casualty who can swallow may take oral fluids, especially when evacuation is delayed.

Medications

Know the logic behind tactical pain control: a casualty who can still fight gets non-sedating oral medications, while moderate to severe pain calls for fentanyl or ketamine. Ketamine is favored for a casualty in or at risk of shock because it doesn’t drop blood pressure the way opioids can. Keep naloxone ready with opioids, and know when antibiotics, antiemetics, and nerve agent and cyanide antidotes are indicated.

Neuro, Orthopedic, and Burn Care

Head injury: Use the Glasgow Coma Scale for baseline and trending. Signs of rising intracranial pressure include a declining GCS, a unilaterally dilated pupil, posturing, and Cushing’s triad (hypertension with widening pulse pressure, bradycardia, and irregular respirations). Prevent hypoxia and hypotension.
Spinal injury: Penetrating trauma alone isn’t an indication for spinal immobilization, and trying it under threat can cost lives. Blunt trauma, blast, and an unconscious casualty call for more caution.
Burns: Estimate TBSA with the Rule of Nines. The Parkland formula is 4 mL × weight in kg × %TBSA over 24 hours, with half in the first 8 hours from the time of the burn. The Rule of Tens sets an adult’s starting rate at %TBSA × 10 mL/hr for patients 40 to 80 kg, adding 100 mL/hr for each 10 kg above 80 kg.

Mass Casualty Triage

START sorts adults by respirations, perfusion, and mental status. SALT starts with a global sort (walk, wave, or still), then allows quick lifesaving interventions such as controlling major hemorrhage, opening the airway, chest decompression, and antidote autoinjectors before assigning categories.

Common Tactical Casualty Care Traps on the TP-C

Treating in the wrong phase: Picking IV access, airway management, or a full assessment while the team is still under fire.
Loosening a tourniquet too soon: Choosing conversion for a casualty in shock or with a short evacuation time.
Reaching for crystalloid: Selecting a liter of normal saline for hemorrhagic shock.
Chasing a normal blood pressure: Forgetting permissive hypotension, or forgetting the higher target with TBI.
Using outdated dosing: Older protocols gave TXA as 1 g plus an infusion.
Reflexive spinal immobilization: Choosing a full backboard for an isolated gunshot wound.

Sample Scenarios: How to Reason Through TECC/TCCC Questions

Scenario 1: Bleeding Under Fire

Consider a question where a SWAT officer is shot in the upper thigh during a warrant service. Blood is pulsing from the wound, and the suspect is still firing. The options are checking the airway, starting an IV, packing the wound, or applying a high-and-tight tourniquet and moving to cover.

The threat is active, so this is the Direct Threat phase. The only intervention that belongs here is stopping the extremity bleed, and a tourniquet does that fastest. Packing needs minutes of pressure you can’t safely give under fire.

Scenario 2: Shock at the Casualty Collection Point

Now imagine the same casualty 25 minutes later at the CCP. The threat is contained, and ground evacuation is 45 minutes out. The tourniquet has stopped the bleeding, but he’s confused, with a weak radial pulse. You have IO access, TXA, and a unit of low-titer O whole blood.

Reassess the tourniquet and check for other bleeding. He’s in hemorrhagic shock within 3 hours of injury, so he needs TXA 2 g and the whole blood, then 1 g of calcium, with a target of a stronger radial pulse and better mentation. Wrap him to prevent hypothermia. Tourniquet conversion is a distractor because he’s in shock, and so is a saline bolus.

How Tactical Casualty Care Connects to the Rest of the TP-C

Tactical Operations: Remote assessment and surrogate care are hemorrhage control by proxy, and your extraction recommendation depends on the casualty’s injuries.
Planning: Where you place the CCP and how far the trauma center is decide how long you’ll be managing shock.
Specialized Medical Care: Cold exposure worsens hypothermia, and hazmat antidotes overlap with medications.
