BP, elevated diastolic BP, increased RR, bounding pulse, decreased

urinary output.

What are signs of Decompensated or Progressive shock? - ANSWERDecreased LOC, decreased systolic BP, narrowing pulse pressure,

tachycardia, weak pulses, rapid shallow respirations, cool and cyanotic

skin, increased lactic acid levels.

What are signs of Irreversible shock? - ANSWER- Obtunded, marked

hypotension and heart failure, bradycardia, bradypnea, organ failure,

acidosis.

C- Crying

C- Consolability

CO2 is a primary regulator of blood flow to the brain and a strong

vasoconstrictor or vasodilator? - ANSWER- Vasodilator

What is a normal ICP level? - ANSWER- 10-20 mmHg

A sustained ICP over what level is considered abnormal? - ANSWER20 mmHg

Cerebral autoregulation maintains a constant cerebral vascular blood

flow as long as the MAP is in what range? - ANSWER- 50-150 mmHg

Normal cerebral perfusion pressure is what? - ANSWER- 60-100 mmHg

Autoregulation maintains a steady state when the CPP is between what?

- ANSWER- 50 - 160 mmHg

When cerebral autoregulation fails, perfusion is dependent on what and

what conditions would complicate this? - ANSWER- MAP, hemorrhage

and hypovolemia

N&V, amnesia, behavior changes, altered loc

Late assessment findings of ICP include. - ANSWER- Dilated

nonreactive pupils, unresponsive to stimuli, abnormal posturing,

widening pulse pressure, reflex bradycardia, decreased respiratory effort.

How long does it take for symptoms to manifest in both acute and

chronic subdural hematomas? - ANSWER- Acute- within 72 hours

Chronic- up to 2 weeks

Assessment findings of chronic subdural hematomas include. -

ANSWER- Altered or steady decline in LOC, headache, loss of

What is the GCS score for mild traumatic brain injury? - ANSWER- 13-

15
