Q

During our physical exam portion of a neuro exam what features/structures are we looking at or observing for?

A
  1. Size/shape of head
  2. Awake & alert vs. drowsy/lethargic
  3. Activity
    • (spontanous or only responsive to certain stimuli)
  4. Tone
    • Hypertonic vs. hypotonic
  5. Symmetry
    • Movements equal and bil?
  6. Facial features
    • Can clue us into different syndromes
  7. High-pitched cry “Neuro cry”
  8. Respiratory Pattern
    • Periods of apnea? or hyperventilation?
  9. Muscular activity/coordination
    • Twiching or ticks? Unusal movements?

Q

True or false: Assessing impairment in infants and very young children is no harder than assessing an adult patient. Just more time consuming?

A

False. It can be very problematic to assess infants and very young children.

There are pedicatric coma scales for ages 2 and younger for this reason

Q

What medications might be used in the nursing care of increased ICP?

A
  1. Mannitor: osmotic diuretic used to decrease ICP. Works quickly within 1-5 mins and is rapidly excreted by the kidneys so it carries lots of sodium and water with it. CAUTION: HYPOVOLEMIC RISK
  2. Hypertonic solutions: Increases sodium level and pulls fluid into the vascular system. MOst helpful in patients who are hypotensive and hypervolemic

Q

What can we have a family member do to help try and bring down ICP?

A

Sometimes a family member just placing a hand on the patient can soothe them and decrease the ICP. If we utilize this method it is important that we teach the family member not to rub.. as this could stimulate and increased ICP

Q

What is the patho of a epidural hemorrhage?

A
  1. Blood accumulates rapidly between the skull & dura

Q

What should we know about the meningeal artery in an epidural hemorrhage?

A
  1. It becomes embedded into the skull itself so a break in that bone can tear the artery which causes the arterial bleed.
  2. However, this is not often seen in kids under 2 since it not yet embeded into bone.

227
Q

How is a myelomeningocele dx

Spina Bifida Cystica

A
  1. Prenatal detection
    • ultrasound

Q

What are the 3 phases of GBS?

    • Acute peripheral motor weakness (symmetric)
  2. CSF anaylsis
  3. EMG findings (TENS UNIT)
240
Q

Treatment of GBS includes?

A
  1. Airway support (may need trach or intubation if paralysis moves up neck)
  2. IVIG

  5. GABAPENTIN
  6. Rehab
241
Q

True or false: GBS effects the patient cognitively so you do not have to talk to your patient?

A

False– they are cognitively away and scared so talking is encouraged

242
Q

What can contribute to best possible outcome for GBS?

A
  1. Younger age
  2. No mechanical resp. assistance needed

A

in reverse order

rate r/t degree of involvement– weeks to monthss
