Table 21-6 has diagnostic tests for neurologic disorders pg 480 – 484. Good reference for any testing we discuss in these 4 chapters

PHYSICAL ASSESSMENT Vital signs: Rise in systolic pressure and a widening pulse pressure may indicate an intracranial pressure (ICP) increase ICP increase also possibly slow, bounding pulse, irregular and labored breathing Mental function and level of consciousness: Glasgow Coma Scale (table 21-7) FOUR (Full Outline of UnResponsiveness) Newer, used for comatose or intubated patients who can’t speak Score 0-4 in four categories: eye, motor, brainstem, respiratory

NEUROLOGIC AND NEUROMUSCULAR STATUS Orbital pressure Pinch the trapezius Mandible pressure Sternal rub: Purposefully withdrawing from the stimulus or an attempt to push it away Nonpurposeful response – Posturing Failure to respond at all Decorticate (flexor) posturing – cortex injury/ better Decerebrate (extensor) posturing – brainstem injury

PHYSICAL ASSESSMENT Pupillary reactions – test brainstem Controlled by cranial nerves II & III Direct reflex – eye with the light CONSTRICTS!!! Consensual reflex – opposite pupil CONSTRICTS!!! Pupils that remain fixed and dilated = brain damage One pupil that remains fixed and dilated = increased ICP Table 21-8 has good pupil info “Neuro” check (LATE RESPONSE) Vital signs, level of consciousness (LOC), pupil reaction, and motor function Can be ordered q 15 min to q 8hrs

SAFETY ALERT PG 488 If changes in data indicate a rise in ICP or a decrease in LOC, it is important to alert the charge nurse and physician. This is even more important when possible intracranial bleeding is suspected as it may indicate an emergency situation.
