Q

treatment for concussion

A

-keep them awake for as long as possible
-rest until symptoms resolve
-resume activities gradually

23
Q

Epidural hemorrhage

A

*Bleeding between the skull and the dura

24
Q

Classic clinical picture of epidural hemorrhage consist of

A

momentary unconsciousness, followed by a normal period, then followed with lethargy and coma due to blood accumulation in the epidural space and compression of the brain

25
Q

Subdural hemorrhage

A

*Bleeding between the dura and the arachnoid membrane

26
Q

presenting signs for subdural hemorrhage

A

irritability, vomiting, increased head circumference, bulging fontanels in infants, lethargy, coma, or seizures.

27
Q

Cerebral edema

A

*Associated with traumatic brain injury
*Increased ICP with herniation

28
Q

Cerebral edema peaks at

A

24 to 72 hours after injury and may account for changes in a child’s neuro status.

29
Q

Therapeutic Management ofHead Trauma

A

-NPO until it is determined that vomiting will not occur.
-Sedating drugs are commonly held in the acute phase.
-Acetaminophen for headache.
Surgery
-Scalp lacerations are sutured.

30
Q

Reye’s Syndrome

A

*A disorder defined as toxic encephalopathy associated with other characteristic organ involvement

31
Q

Reye’s Syndrome is characterized by

A

*fever, profoundly impaired consciousness, and disordered hepatic function

32
Q

most common cases of reyes syndrome follow

A

common viral illness (influeza and varicella)

33
Q

what medication is associated with reyes syndrome

A

*aspirin therapy for fever and development of Reye’s syndrome

34
Q

what is the definitive diagnosis for reye’s syndrome

A

liver biopsy

35
Q

a build up of ammonia in reyes syndrome will cause

A

sudden behavioral shift

36
Q

therapeutic management for reyes syndrome

A

*Early diagnosis and aggressive therapy

37
Q

seizure disorders

A

“transient occurrence of signs and/or symptoms due to abnormal excessive and synchronous neuronal activity in the brain”.

38
Q

seizures are determined by

A

site of origin

39
Q

The manifestations of seizures

A

unconsciousness or altered consciousness, involuntary movements, and changes in perception, behaviors, sensations, and/or posture

40
Q

Epilepsy

A

chronic brain disorder characterized by Two or more unprovoked seizures

41
Q

partial seizure

A

a seizure that affects only one part or one side of the brain, local onset

42
Q

generalized seizure

A

a seizure that affects both sides/hemispheres of the brain without local onset

43
Q

goal for seizure disorders

A

*To control seizures or reduce the frequency and severity

44
Q

Therapeutic Management of Seizure Disorders

A

-discovery and correction of cause
-medication (start at lowest dose possible) and gradually increase until seizures are controlled)

45
Q

febrile Seizures

A

Seizures that result from sudden high fevers, particularly in children between 6mo. and 3 years

A

*an imbalance in the production and absorption of CSF

47
Q

hydrocephalus

A

accumulation of fluid in the spaces of the brain
