SpO2 data on the PCC flowsheet is not shown with a triangle. The flowsheet uses a different symbol to denote oxygen saturation, and the SpO2 value appears in its own field with the percent value. Recognizing the correct symbol helps you read vital signs quickly and accurately. Because the statement claims a triangle, and the actual representation for SpO2 is not a triangle, the statement is false. SpO2 is displayed on the flowsheet, just not with a triangle, so rely on the chart legend or the SpO2 field to identify it correctly.

MARCH organizes battlefield care by prioritizing threats in order of immediacy: control massive bleeding first, because uncontrolled hemorrhage kills fastest; then secure the airway to prevent airway collapse or obstruction; next ensure adequate breathing to oxygenate the patient; then attend to circulation to maintain perfusion and continue bleeding control; and finally prevent hypothermia to preserve clotting and overall stability. This sequence reflects what saves the most lives on the field. The option that fits this sequence uses the standard terms: Massive hemorrhage, Airway, Respirations, Circulation, Hypothermia prevention. The wording differences in the other choices—such as bleeds vs hemorrhage, breathing vs respirations, or protection vs prevention—do not align with the conventional terminology and emphasis of MARCH. So this choice best matches the established protocol and rationale behind the priority order.

Disability in the trauma assessment is a quick check of brain function. It centers on neurologic status, primarily how awake or altered the patient is and how they respond to stimuli. You assess level of consciousness—often with a simple scale or by noting alertness, orientation, and ability to follow commands—and you also check pupil size and how they react to light. These signs help you spot neurologic injury or deterioration early, which is crucial for making decisions about further care and transport. This step is distinct from airway checks (ensuring the airway is open) and breathing checks (how effectively the patient is ventilating) as well as from circulation checks (looking at blood flow and perfusion).

These signs come from assessing acute limb compartment syndrome, where growing pressure within a muscle compartment compromises blood flow. The six P’s you should look for are Pain, Pallor, Paresthesia, Pulselessness, Paralysis, and Poikilothermia. Pain is typically severe and out of proportion to exam findings, signaling early involvement. Pallor reflects pale skin from reduced blood flow. Paresthesia indicates nerve irritation or injury. Pulselessness means the distal pulse is absent, showing significant arterial compromise. Paralysis points to loss of motor function from nerve or muscle damage. Poikilothermia describes a cooler limb due to poor perfusion. Pressure itself is not listed as one of the six P’s; it’s the underlying factor causing the syndrome, not a presenting sign by the mnemonic. Clinically, rising intracompart ment pressure leads to these signs, and recognizing them promptly is crucial because urgent decompression is needed to prevent lasting damage.
