A patient presents with dilated pupils and vomiting. Which stage of intracranial pressure is this most likely indicative of?
Compensatory stage
Refractory stage
Initial stage
Progressive stage
The Correct Answer is D
A. The compensatory stage involves subtle changes as the brain attempts to maintain normal ICP, typically without severe symptoms like dilated pupils.
B. The refractory stage is the final stage where brain injury is irreversible and signs are severe, often including coma.
C. The initial stage usually shows minimal or no symptoms.
D. The progressive stage of increased ICP is characterized by worsening neurological signs, including vomiting, dilated pupils due to cranial nerve compression, and decreased level of consciousness. These symptoms indicate that intracranial pressure is rising and beginning to impair brain function.
