South California EMS Medical Block Practice Test

Early compensatory response in shock is what this item focuses on. In this stage the body keeps blood pressure through sympathetic-driven mechanisms like tachycardia and vasoconstriction, preserving perfusion to vital organs despite reduced circulating volume. Because these adjustments can maintain a normal blood pressure, the patient may seem relatively stable even though tissue perfusion is still challenged. You’ll often see a fast, anxious patient with cool, clammy skin and rapid breathing, with blood pressure that looks normal or only lightly affected. If this compensatory phase is not enough and the underlying problem worsens, the patient moves into decompensated shock, where blood pressure falls and mental status deteriorates, and eventually irreversible shock if treatment doesn’t reverse the cascade.
