How does fluid accumulate in the middle ear during otitis media?
A. Fluid accumulates in the middle ear as blood vessels become increasingly permeable in response to chemical mediators of inflammation
Fluid accumulates in the middle ear as blood vessels become increasingly permeable in response to chemical mediators of inflammation: This is correct. During otitis media, inflammation can cause blood vessels to become more permeable, allowing fluid to accumulate in the middle ear.
B. Fluid accumulates in the middle ear as blood vessels become semi-permeable in response to chemical mediators of inflammation
Fluid accumulates in the middle ear as blood vessels become semi-permeable in response to chemical mediators of inflammation: This is not correct. Blood vessels do not become semi-permeable in response to chemical mediators of inflammation.
C. Fluid accumulates in the outer ear as blood vessels become increasingly permeable in response to chemical mediators of inflammation
Fluid accumulates in the outer ear as blood vessels become increasingly permeable in response to chemical mediators of inflammation: This is not correct. Fluid accumulation during otitis media occurs in the middle ear, not the outer ear.
D. Fluid accumulates in the tympanic membrane as blood vessels become increasingly permeable in response to chemical mediators of inflammation
Fluid accumulates in the tympanic membrane as blood vessels become increasingly permeable in response to chemical mediators of inflammation: This is not correct. Fluid accumulation during otitis media occurs behind the tympanic membrane (eardrum), not in it.

Diffuse axonal injury follows blunt head trauma or shaking that jars the brain against the skull. Which mechanical below would result in diffuse brain injury. Select all that apply. (Select All that Apply.)
A. rotational
Rotational: This can result in diffuse brain injury. Rapid rotation of the brain inside the skull can cause the long connecting nerve fibers (the axons) to tear, leading to diffuse axonal injury.
B. deceleration
Deceleration: This can result in diffuse brain injury. Sudden deceleration motion of the brain inside the skull can cause the long connecting nerve fibers (the axons) to tear, leading to diffuse axonal injury.
C. acceleration
Acceleration: This can result in diffuse brain injury. Sudden acceleration motion of the brain inside the skull can cause the long connecting nerve fibers (the axons) to tear, leading to diffuse axonal injury.
D. blunt force
Blunt force: This is not a mechanical force that would result in diffuse brain injury by itself. However, blunt force trauma can cause rapid rotation or sudden acceleration/deceleration motion of the brain inside the skull, which can result in diffuse axonal injury.
E. fall
This can result in diffuse brain injury. A fall can cause rapid rotation or sudden acceleration/deceleration motion of the brain inside the skull, leading to diffuse axonal injury.
Parasomnias are unusual behaviors occurring during sleep which behavior is not parasomnias?
A. restless leg syndrome.
Restless leg syndrome: This is considered a parasomnia. Restless leg syndrome is a sleep-related movement disorder that causes an irresistible urge to move the legs, often accompanied by uncomfortable sensations.

D. Unstable sleep hygiene
Unstable sleep hygiene: This is not considered a parasomnia. Sleep hygiene refers to habits and practices that promote good sleep, such as maintaining a regular sleep schedule and creating a comfortable sleep environment
Which of the following describes decerebrate posturing?
A. Internal rotation and adduction of arms with flexion of elbows, wrists, and fingers
Internal rotation and adduction of arms with flexion of elbows, wrists, and fingers: This describes decorticate posturing, which is another type of abnormal body posture that can occur due to severe brain damage. It is different from decerebrate posturing.
B. Back hunched over, rigid flexion of all four extremities with supination of arms and plantar flexion of the feet
Back hunched over, rigid flexion of all four extremities with supination of arms and plantar flexion of the feet: This does not describe decerebrate posturing.
C. Back arched: rigid extension of all four extremities
Back arched: rigid extension of all four extremities: This describes decerebrate posturing, which involves the arms and legs being held straight out, the toes being pointed downward, and the head and neck being arched backward.
D. Supination of arms, dorsiflexion of feet
Supination of arms, dorsiflexion of feet: This does not describe decerebrate posturing.
