What is primary injury? What is secondary injury to brain? | Primary: initial damage to brain incl contusions/lacerations/torn blood vessels. Secondary: evolves over hours/days from poor nutrient/O2 delivery |
simple, comminuted depressed or basilar are all terms to describe what kind of head trauma | skull fractures |
Define simple vs comminuted vs depressed | simple: break in continuity of bone comminuted: splintered/multiple fracure line depressed: bones of skull forcefully pushed downward. Ex. fracture at base of skull or basilar skull fracture |
Closed vs open brain injury | closed: head collides and brain tissue is damaged but no opening thru skull or dura. Open: obj penetrates and damages soft brain or injury open skull to expose brain |
The duration of ________ is an indicator of the severity of the concussion | unconsciousness |
Memory lapse or unconsciousness lasting <30min reveal what concussion? | mild |
Memory lapse, posttraumatic amnesia, lasting < 6h describe what kind of concussion | classic |

A cerebral contusion is defined as | moderate to severe head injury, bruised brain and damage in specific area. |
Hemotomas can happen in what three areas of the brain? | epidural(above dura), subdural(below dura), intracerebral(w/in brain) |
Pt presents with an epidural hemotoma, a brief loss of consciousness followed by lucid interval, if ICP incr what s/s will be pt show? | restless, agitated, confused, LOC, dilated/fixed pupils |
If ICP gets elevated does the CPP go up or down? | down, so oxygenate, elevate head. A decr in CPP can cause a decr in cerebral perfusion and brain hypoxia/ischemia. |
When assesing unconscious pt and GI system, what should you monitor if pt is getting corticosteroids? | GI hemorrhage, so check for decr hemoglobin |
You pt has severe hypotension, how will this affect the CPP and what will be done to correct it? | hypotension will cause vasoconstriction, decr in CPP and treated with IV fluids or vasopressin |
Ways to control ICP in pt with brain injury | elevate HOB Keep head/neck aligned, no twisting prevent Valsava with stool softeners Maintain normal temp Give O2 for paO2>90 Keep fluid balance Avoid excess suction, pain Give sedatives to decr agitation Keep CPP >70 Give seizure meds as prophyl |
What are paraplegia and tetraplegia in a spinal cord injurcy (SPI)? | para: paralysis of lower body tetra: (former quadraplegia) paralysis of all four extremities |
What is affected in an incomplete SCI? complete? | sensory/motor/both fibers below lesion Complete: total loss of sensation and voluntary muscle control below lesion |
What is usual medical tx for SCI in emergency? | methylprednisolone |
Need for a ventilator is for injury to where in spinal cord? | C1-C3 |
A pt has motor deficits in upper extremities. There is edema in cervical area, what syndrome is this? | central cord syndrome, damage in middle of cord |
Pt can feel his left side, but not move it. He can move his right side, but not feel it. What is this incomplete SPI called? | Brown-Sequard Syndrome |
Pt can't move, feel pain or pressure in his lower extremities, but can feel them vibrate and temperature, this syndrome is? | Anterior Cord Syndrome |
In pt with SCI, and no bladder control, what is used to relieve bladder distention and UTI? | Intermittent catheter or indwelling if needed |
This is found in pt with cord lesions above T6, bowel/bladder distention, ingrown toe nails noxious stimuli after SCI | autonomic dysreflexia |
What is medical mgmt for DVT in SCI | 1. fluids 2. dopamine(help heart, not x BBB) 3. Epi/Norepi 4. atropine if bradycardia severe |
What drug helps with spastic muscles? | Baclofen (antispasmodic) |
What is biggest nsg consideration with paraplegias | skin integrity |
Paraplegias are at risk for infection in what three ways | urinary tract, respiratory tract, pressure ulcers |
