90
Q

Assessment of CN I (Olfactory Nerve)

A

Normal Findings
- Correctly identifies scent
presented to each nostril

Abnormal
- Inability to smell (neurogenic anosmia) or identify the correct
scent

91
Q

Causes of abnormal findings in CN I

A
  • Olfactory tract lesion or tumor
  • Frontal lobe lesion
  • Congenital
  • Nasal or sinus problems
  • Viral upper respiratory tract
    infection
  • Smoking
  • Use of cocaine
92
Q

a tumor that grows in the nasal cavity

A

Olfactory Neuroblastoma /
Esthesioneuroblastoma

93
Q
  • A congenital disorder.
  • Normally (embryogenesis), GnRH neurons originate in the olfactory mucosa which later on migrates to the hypothalamus.
  • Defective formation of the olfactory bulb leads to defective migration
    of the GnRH cells to the hypothalamus. The deficit in the GnRH hormone production by the hypothalamus results in decreased levels of sex steroid responsible for sexual maturity and development of
    secondary sexual characteristics
  • Presents with absence of secondary sex characteristics (enlarged
    breasts, widening of hips, facial hair, Adam’s apples, pubic hair) and hypo- or anosmia
A

Kallmann Syndrome

94
Q

Assessment of CN II (Optic Nerve)

A
  • Use Snellen chart
  • ask patient to read something to assess near vision
95
Q

Normal Findings of CN II
- vision

A
  • Client has 20/20 vision on
    both eyes
  • Client reads print at 14
    inches without difficulty
96
Q

Abnormal Findings of CN II
- Vision

A
  • Difficulty reading chart, missing letters, leaning forward, and squinting
  • Reads print by holding closer than14 inches or holds print farther
    away as in presbyopia, which occurs with aging
97
Q

Normal Findings of CN II
- visual Field

A

Full visual fields

98
Q

Abnormal Findings of CN II
- visual Field

A

Loss of visual fields may be seen in retinal damage or detachment, with lesions of the optic nerve, or with
lesions of the parietal cortex

99
Q

Normal Findings of CN II
- using ophtalmoscope to view retina and optic disc

A

Normal Findings
- Round red reflex is
present, optic disc is 1.5
mm, round or slightly
oval, well-defined margins, creamy pink with paler physiologic cup. Retina is pink

Abnormal Findings
- Papilledema (swelling of the optic nerve) results in blurred optic disc margins and dilated, pulsating
veins.
- Optic atrophy occurs with brain tumors

100
Q

Assessment of
CN III (Oculomotor),
IV (Trochlear), and
VI (Abducens)
- Inspect margins of the
eyelids of each eye

A

Normal Findings
- Eyelid covers about 2mm
of the iris
Abnormal Findings
- Ptosis (drooping of the eyelid) is seen with weak eye muscles such
as in myasthenia gravis

101
Q

occurs with brain
tumors

A

Optic atrophy

102
Q

(drooping of the eyelid)

A

Ptosis

103
Q

Assessment of
CN III (Oculomotor),
IV (Trochlear), and
VI (Abducens)
- Assess extraocular
movements. If
nystagmus is noted,
determine the direction of the fast and slow phases of movement

A

Normal Findings
- Eyes move in a smooth,
coordinated motion in all
directions (the six
cardinal fields)

Abnormal Findings
- Nystagmus

of the eyes): cerebellar
disorder

A

Nystagmus
