Q

How do you assess the optic nerve? (CN II)

A
  • Assess visual acuity using the Snellen chart, stand 3-6m away from pt and get them to cover one eye at a time whilst reading the letters.
  • Assess pupils by using a pen torch
  • Get pt to look at your face and hold both your arms to the side and wiggle your finger and get them to state which one you are doing.

A
  • There are 3 divisions of the trigeminal: ophthalmic, maxillary and mandibular.

Q

How would you assess the vestibulocochlear nerve (CN VIII) ?

A
  • Assessing pts hearing and balance
  • Whisper a number close to the pts ear and ask them to repeat it, move further away and do the same thing on both ears.

  • Webber’s test- place the fork in the middle of the forehead and ask the pt if they can hear it in both ears.
  • Assess balance by getting pt to march on the spot, perform rhombergs test, heel to toe walking (tandem gait), walk on their toes and heels.

A
  • Look for rapidly alternating movements

A
  • A test which assesses the pts balance.
    Get the pts to stand with their feet together and their arms by their side, get them to close their eyes and say still. Stand next to them ready to catch them.

Q

What is Babinskis reflex?

A
  • Works on unconscious pts
  • Run a pointed object from heel to the toes
  • Pathological reflex
  • Positive sign indicates disturbance of the CNS

A
  • With unconscious pts, if you hold their eyes open, it should look like they’re staring up at you even if you turn their head, if you’re not concerned of c spine.

Q

Where are you most likely to have a c spine injury?

A
  • At c1,2 or C6,7
17
Q

Dermatones

A
  1. CERVICAL C1-7
  2. THORACIC T1-12
  3. LUMBAR L1-5
  4. SACRAL S1-5
18
Q

HX

A
  • LOC- how long for, witnessed? Seizure like activity
  • Amnesia- retrograde (since before injury) or anterior grade-since the incident/injury
  • Mechanism- does hx match it?
  • Previous head/neck injury?- more vulnerable
  • > 65- comorbiidities, vulnerabilities
    -Alcohol/drugs - ?GCS
  • Headache after head injury- may be a sign of raised ICP, red flag if delayed
  • Vomiting- more than one is a concern so is if it’s with little effort
  • Behaviour after injury- is it normal?
  • What may have caused this incident?- postural drop?
  • Give head injury s&s to look out for to the pt and to someone else!
19
Q

HEADACHES:

A
  • Brain can interpret pain but can’t feel it!
20
Q

Primary headaches

A
  • The source of the pain is within the head itself.
  • Cluster headache- Neurological
  • Migarines- Vascular
  • Tension headache- Muscular
  • Diagnosis of exclusion, things that will not necessarily kill you!
21
Q

Secondary headaches:

A
  • Referred pain, source is not the head, it may be: the sinuses, ears, nose, mouth, referred pain from the neck, shoulders and upper back!
22
Q

Cluster headaches

A
  • Sharp, unilateral periorbital pressure
  • Repeated attacks, headaches are in clusters
  • Autonomic features- sweaty, lacrimation (tears)
  • Rare
  • Often diagnosed and phone when pain is so severe
  • High flow o2 treats the headaches
  • AKA suicide headaches
23
Q

MIGRAINE

A
  • More common in women
  • Known CVA mimick
  • Recurrent
  • Diagnosed by 40
  • Last up to 7hrs
  • Pain is unilateral, if it’s not, it’s not a migraine!!!
  • May present with auras- visual is very common
  • Nausea & vomiting
  • Often diagnosed after 5-10 episodes
24
Q

Occipital neuralgia

A
  • Feel like the back of the head is on fire, shooting pain
  • Gabalin is first line treatment
  • Definitive treatment is nerve block
  • Palpate the headache as it can make the pain better/worse
25
Q

Subarachnoid haemorrhage

A
  • Starts as a headache
  • Rapid onset, thunderclap headache, feeling faint, nausea and vomiting, stiff neck
  • 50% presents with a mild headache that worsens or a sudden headache that resolves!
  • Easily seen on a CT
    -FMHX is risk factor
26
Q

Neoplastic- Tumours

A
  • Benign & Malignant- benign can be an issue too as it may be causing an occlusion due to its size and it may be inoperable.
  • Ask about hx of neoplasm
  • new onset of headache in a pt with an intracranial tumour requires urgent review.
  • Consider rise in ICP
  • Possible metastasis?
  • Severe constant, progressive pain worsening on walking & nausea and vomiting may be due to a tumour!
27
Q

CNS INFECTION

A
  • Rash is a very late sign
  • CHECK THE CONJUNCTIVA for a rash- especially in black skin
  • Immunisation hx is key- Adolescence
28

- Fever
* May require antibiotics if symptoms worsen

32
Q

Tension headache

  • Most common headache
  • Stress or fatigue provoke this
  • Generalised or posterior/ occipital
  • Diagnosis of exclusion!!
