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.

Explanation
When caring for a child with an open fracture, the nurse should carefully assess for signs and symptoms of infection. An open fracture refers to a fracture where the bone is exposed through the skin, creating a direct pathway for microorganisms to enter and cause infection. Infection is a significant concern in open fractures and can lead to serious complications if not identified and treated promptly. Signs of infection may include increased pain, swelling, redness, warmth, purulent drainage, fever, or systemic signs of infection such as elevated white blood cell count.
Osteoarthritis in (option A) is incorrect because it, is not an immediate concern in the care of a child with an open fracture. Osteoarthritis refers to degenerative joint disease that typically develops over time and is not directly related to the acute management of an open fracture.
epiphyseal disruption in (option B) is incorrect because it, refers to an injury involving the growth plate (epiphyseal plate) that can affect bone growth and development. While it is a potential concern in fractures that involve the growth plate, it is not specific to open fractures and may not be an immediate priority in the initial assessment of an open fracture.
periosteum thickening in (option D) is incorrect because it, may occur in response to injury and fracture healing, but it is not specifically associated with open fractures and is not a primary focus in the initial assessment of an open fracture.
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.
