Chapter 12, Problem 5CCS
39-Year-Old Female with Traumatic Brain Injury
Margaret Bryans, a 39-year-old female, lost control while skiing and hit her head on a tree. She regained consciousness en route to the hospital and appeared agitated and combative. Paramedics observed that she had a right hemiparesis (muscle weakness), with a nearly complete paresis of her right upper extremity and a partial paresis of the right lower extremity. A head CT scan revealed an acute subdural hematoma and an extensive subarachnoid hemorrhage. Doctors noted that she was able to follow commands from medical personnel. However, she could only speak haltingly, using simple words.
Surgery to remove large clots from the subarachnoid space was performed immediately. Two weeks after the surgery, she showed significant improvement in her speech and motor function.
5. NCLEX-STYLE Mrs. Bryan’s subdural and subarachnoid bleeding most likely interfered directly with which of the following?
a. The blood supply to the scalp
b. The blood supply to the cerebral cortex
c. The removal of cerebrospinal fluid
d. The creation of cerebrospinal fluid

10-year-old female was admitted due to episodes of generalized seizure-like activity that started a day prior to admission. 14 days prior to admission(PTA), she was playing with friends in their backyard when an object cut her leg. Despite having a deep cut, she continued on her game. 10 days PTA, she experienced stiffness of the neck, difficulty of swallowing and chewing. the signa and symptoms persisted until 7 days PTA, when she experienced abdominal rigidity, sweating, fever and tachycardia. the patient condition worsened until admission.

Specific information about…
Please describe an example of both a primary and secondary spinal cord injury.
Our discussion this week pertains to Spinal Cord Injuries. Primary spinal cord injury involves damage to vertebral or neural tissues from compression, traction, or shearing forces. Secondary spinal cord injury is related to ischemia, excitotoxicity, inflammation, edema, oxidative damage, and activation of necrotic and apoptotic cell death; it begins within minutes after injury and continues for weeks.
Assignment Instructions:
Describe an injury. Some learners will use the same injury, such as a fall off of a horse. Describe how the patient experienced both primary and secondary injuries. Be sure to describe symptoms, implications, and testing that helped clinicians to classify the injury into these categories.
