Emergency Medical Technician (EMT) Basic Certification Practice Exam

Which symptom is typically associated with a progressive increase in intracranial pressure?

1. Increased alertness

2. Pupils reacting to light

3. Edema

4. Cold extremities

The correct answer is: Edema

A progressive increase in intracranial pressure is commonly associated with edema, particularly cerebral edema, which is the swelling of brain tissue due to increased fluid accumulation. As intracranial pressure rises, it can lead to various symptoms, but edema specifically reflects the body's response to the pressure and can result in further complications if not addressed. In contrast, increased alertness is not typically seen with rising intracranial pressure; rather, a decrease in consciousness or alertness would be more common. Pupils that react normally to light suggest normal neurological function; however, as pressure increases, pupils may react abnormally, indicating a problem. Cold extremities are often a sign of peripheral vascular compromise and do not directly correlate with increased intracranial pressure. Understanding the relationship between intracranial pressure and symptoms helps in recognizing the severity of a neurological condition and guiding appropriate intervention.
