C. Palpate for distended bladder

D. Assess pupil response and Glascow coma scale

Clients with C5 cervical injury are at risk of respiratory failure. The Diaphragm is innervated at level of C4. 

300

Early signs of ICP and interventions




***Change in LOC

-Vomiting not proceeded by nausea

-Extreme headache

-Sluggish pupillary changes, Dilation on same side as injury


Nursing interventions for brain injury/increased ICP 

- Monitor resp status and lung sounds (maintain patent airway): any lvl of hypoxia or hypercapnia can effect CPP 

- Position head in neutral position w/ HOB 30º

- Avoid stimuli & activities that may increase ICP (Ex: valsalva maneuver, hip flexion, abdominal distention) 

- Protect Pt from stress (Ex: calm & quiet environment) 

- Monitor fluid status carefully (I/Os hourly) 

- Strict aseptic technique

300

What is the term for incomplete SCI that results in loss of motor function on the side of the injury, and loss of sensation on the opposite side?

Brown-Sequard Syndrome

300

How would you test CN XI: Accessory?

-shrug shoulders and look for symmetry

-turn head side to side

300

A patient with a closed head injury has a respiratory rate of 30 and irregular, a blood pressure of 198/110mmHg, and a pulse rate of 48. The nurse is reporting these vitals to the PCP because they indicate:

A. Neurogenic shock

B. Cushing's triad

C. A pending seizure

D. Stroke

B: Cushing's triad


-Widening pulse pressure

-Bradycardia

-Irregular respirations

300

During an assessment, the nurse determines that the spinal shock in a patient being treated for C6 spinal cord injury has resolved. What did the nurse assess?

A. Urine output of 45ml over the last hour

B. Blood pressure of 110/66mmHg

C. Positive perianal reflex

D. Areflexia of the ankle reflexes

C: Positive perianal reflex

The return of this reflex indicates resolution of spinal shock

400

A patient's blood pressure is 152/96 and ICP is 20. What is the patient's cerebral perfusion pressure?

95mmHg


CPP (Normal is 60-100mmHg)

Formula 

- (CPP = MAP - ICP) 

MAP formula 

- (MAP = (SBP + 2[DBP]) / 3)

400

What is the term for incomplete SCI that results in impaired motor function in the upper extremities and impaired sensation and positioning in lower extremities?

Central Cord Syndrome

400

Which should be part of the patient's plan of care for impaired function of CN IX: glossopharyngeal, CN X: Vagus, And CN XII: hypoglossal

NPO/Speech Consult

400

A 35 year old woman is snowboarding when she falls and crashes down the slope. She briefly looses consciousness and then returns acting normal. She states she feels "fine" and doesn't need medical attention. What should the nurse infere from the scenario? and what is the treatment?

A. Subdural Hematoma

B. Epidural Hematoma

C.Concussion

D. Everything's fine

B: Epidural Hematoma and emergency craniotomy

**This is a arterial bleed

Patient may have a brief loss of consciousness with return of lucid state; then as hematoma expands, increased ICP will often suddenly reduce LOC.

An emergency situation!

Spinal injuries above T6 are at risk for autonomous dysreflexia. The most common triggers are distended bladder or bowel.

Other interventions:

HOB raised atleast 45 degrees to reduce BP


500

Decerebrate


Whereas "Decorticate" hands are adducted to the "Core"

500

Key difference between Spinal Shock and Neurogenic Shock


Spinal shock shows no reflexes below LOI —> no signals complete the reflex arc even in the intact portion of the spinal cord; flaccid paralysis —> loss of motor function

-Flaccid paralysis, Loss of sensation, Absent sphincter reflexes below injury level


Neurogenic Shock

-Bradycardia, Low BP, Irregular temperature, Poikilothermia

D. Decreased cerebral perfusion pressure (CPP)

E. Increased Urine Output
