Which statement best describes a subdural hematoma?
Bleeding occurs between the dura and the skull.
Bleeding is generally arterial, and brain compression occurs rapidly.
Bleeding occurs between the dura and the cerebrum.
The hematoma commonly occurs in the pretemporal region.
The Correct Answer is A
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.

Correct Answer is A
Explanation
A change in status that should alert the nurse to increased intracranial pressure (ICP) in a child with a head injury is confusion and altered mental status. As intracranial pressure increases, it can affect brain function and lead to neurological changes, including confusion, disorientation, irritability, decreased level of consciousness, or other alterations in mental status. These changes indicate that the brain is being compressed and compromised, and immediate intervention is required.
Option B, increased diastolic pressure with narrowing pulse pressure in (option B) is incorrect because it, can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or systemic conditions. It is important to consider the overall hemodynamic status of the child and assess for additional signs and symptoms of increased ICP.
irregular, rapid heart rate in (option C), can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or other medical conditions. Assessment of heart rate should be considered along with other signs and symptoms of increased ICP.
rapid, shallow breathing, in (option D) can be a sign of increased ICP, but it is not specific to head injuries and can be influenced by other factors such as pain, anxiety, or respiratory conditions. Respiratory assessment should be considered along with other signs and symptoms of increased ICP.
Correct Answer is C
Explanation
Epispadias is a congenital condition in which the urethral opening is not located at the tip of the penis as is typical but rather along the ventral surface (underside) of the penis. In severe cases, the urethral opening may extend all the way to the bladder.
absence of a urethral opening in (option A) is incorrect because it, describes a condition called urethral agenesis or aplasia, where the urethral opening is completely absent. This is a different condition from epispadias.
a penis shorter than usual for age, in (option B) is incorrect because it is not specific to epispadias and could be caused by various factors unrelated to the condition.
a urethral opening along the dorsal surface (topside) of the penis in (option D) is incorrect because it, is a condition called hypospadias. Hypospadias is another congenital anomaly where the urethral opening is located on the underside or along the ventral surface of the penis, but it is not synonymous with epispadias.
Therefore, epispadias specifically refers to the urethral opening being situated along the ventral surface of the penis.
