During what phase of care is TTA preformed? correct answer: Tactical Field Care (TFC)
What pneumonic is used to prioritize care during the TTA?
... [Show More] correct answer: MARCH PAWS
What is a blood sweep? correct answer: A blood sweep is your initial casualty evaluation. It should be a rapid head-to-toe check for any unrecognized life-threatening bleeding
What is the proper distance a deliberate tourniquet should be placed from the bleeding site in TFC? correct answer: 2 - 3 inches above the bleeding site
What is the difference between the need for high & tight (hasty) tourniquets in CUF as opposed to deliberately placed tourniquets in TFC? correct answer: A high & tight (hasty) tourniquet is placed above the clothing as high as possible on the extremity. A deliberate TQ is applied after the wound has been exposed, 2-3 inches above the bleeding site
How long should direct pressure be applied on packed hemostatic dressings? correct answer: 3 minutes
Why is it important to check the pulse after applying a pressure bandage? correct answer: If the bandage is too tight, it could block circulation and the bandage should be loosened
What additional interventions beyond packing with hemostatic dressing and wrapping with a pressure bandage is necessary to stop the bleeding from a groin wound? correct answer: PDD is needed to secure the dressing
What is the best position for a conscious casualty who is breathing on their own? correct answer: A comfortable position of choice that allows them to breathe, including sitting up
Why are casualties placed in the recovery position? correct answer: A comfortable position of choice that allows them to breathe, including sitting up
What are two methods that can be used to open an airway? correct answer: - Head-tilt / chin-lift method
- Jaw-thrust method
How does an nasopharyngeal airway (NPA) provide an open (patient) airway? correct answer: A nasopharyngeal airway provides an open (patent) airway, helping to keep the tongue from falling to the back of the mouth and blocking the airway even if an unconscious casualty's tongue relaxes and partially covers their normal airway
What is a tension pneumothorax? correct answer: As a tension pneumothorax develops, air enters the chest cavity through the wound with every inspiration, but doesn't leave with expiration and is trapped, so every breath adds more air to the air space inside the rib cage and outside the lung, and the pressure inside the chest builds up and causes the lung to collapse. Injured lung tissue acts as a one-way valve, trapping more and more air between the lung and the chest wall. Pressure builds up and compresses both lungs and the heart
How should you treat an open chest wound? correct answer: Treat open chest wounds by applying a vented chest seal completely over the wound during expiration
What should you do if you suspect a casualty has a tension pneumothorax? correct answer: If a chest seal is in place, burp the seal. If there is no improvement after burping the seal perform a needle decompression of the chest
During Circulation in the MARCH PAWS sequence, what interventions should be reassessed? correct answer: Previously applied tourniquets and hemostatic dressings
What are the signs and symptoms of a pelvic fracture? correct answer: - Pelvic pain
- Major lower-limb amputation OR lower near amputations
- Deformities, penetrating injuries, bruising near the pelvis
- Pelvic instability or crepitus
- Unconsciousness or shock
What is shock? correct answer: Shock is inadequate blood flow and oxygen delivery to the body's cells, which leads to organ failure and death
What are the best TACTICAL indicators of shock? correct answer: Decreased state of consciousness (if casualty has not suffered a head injury) and/or an abnormal, weak, absent radial pulse
What is the most important action to prevent hemorrhagic shock? correct answer: Stop the bleeding
Why is it important to keep a trauma casualty warm even if it is a hot environment? correct answer: Even a small decrease in body temperature can interfere with blood clotting and increase the risk of bleeding to death
Casualties in shock are unable to generate body heat effectively
What is the difference between active and passive hypothermia management? correct answer: - Active hypothermia treatment uses heating sources to warm the casualty
- Passive hypothermia strategies will keep the casualty from getting colder, but essentially will not warm the casualty [Show Less]
