Explanation
A subdural hematoma is a type of intracranial bleeding that occurs between the dura mater (the
outermost layer of the meninges) and the skull. The dura mater is a tough membrane that covers
and protects the brain. When a subdural hematoma occurs, blood collects between the dura mater
and the skull, resulting in increased pressure on the brain.
Bleeding is generally arterial, and brain compression occurs rapidly in (Option B) is incorrect because
while bleeding in a subdural hematoma can be arterial, it can also be venous. The rate of bleeding
and brain compression can vary depending on the size and severity of the hematoma.
Bleeding occurs between the dura and the cerebrum in (Option C) is incorrect because the bleeding
in a subdural hematoma does not occur between the dura and the cerebrum (the largest part of the
brain). It specifically occurs between the dura and the skull.
The hematoma commonly occurs in the pretemporal region in (Option D) is incorrect because the
location of a subdural hematoma can vary. While pretemporal region is a possible location, subdural
hematomas can occur in different areas of the brain, depending on the site of injury.

Precocious puberty is defined as the onset of puberty before the age of 8 in girls and before the age of 9 in boys. However, it is important to note that the exact age at which puberty is considered precocious can vary slightly based on different guidelines and individual variations.
Boys: 11 years; girls: 9 years in (option A) is incorrect because it, is close to the general age range, but it is slightly earlier than what is commonly considered precocious puberty.
Boys: 10 years; girls: 9 1/2 years in (option C) is incorrect because it, is also close to the general age range, but it is not as commonly recognized as the age for precocious puberty.
Boys: 9 years; girls: 8 years in (option D) is incorrect because it, is significantly earlier than the usual age for precocious puberty. Puberty occurring at this age would be considered very early and may warrant further evaluation.
