, 1. What This Guide Covers
The referenced Stuvia resource is a 39-page 2021/2022 NR509 final-exam elaboration. Its public preview focuses heavily on
HEENT assessment and includes auditory ossicles, vertigo, Snellen acuity, cranial nerves, ear anatomy, oral lesions,
hearing tests, retinal findings, glaucoma, pediatric findings, and related physical-assessment interpretation.

Use the guide as a framework: recognize the finding → localize the anatomy/physiology → identify the most likely diagnosis
or concern → choose the next assessment or escalation step.
2. HEENT: Ear Assessment
External anatomy: The helix is the curved outer rim; the antihelix lies anterior and roughly parallel to it; the tragus is the
cartilaginous projection anterior to the canal; the lobule is the fleshy lower portion.
Middle ear: The malleus, incus, and stapes are the auditory ossicles. They transmit and amplify mechanical vibrations
toward the inner ear. The Eustachian/auditory tube connects the middle ear with the nasopharynx and helps equalize
pressure.
Inner ear: The cochlea is associated with hearing; the vestibular apparatus/labyrinth is associated with balance and
equilibrium.
• Conductive hearing loss involves impaired transmission through the external or middle ear.
• Sensorineural hearing loss involves the cochlea, CN VIII, or central auditory pathways.
• Otosclerosis classically causes conductive hearing loss through abnormal stapes fixation.
• Age-related hearing loss and prolonged loud-noise exposure are common sensorineural causes.
• A foreign body or cerumen impaction can cause conductive loss.
Rinne: compares air conduction (AC) with bone conduction (BC). Normal/expected is AC > BC. A conductive loss can
produce BC ≥ AC in the affected ear. Weber: sound normally localizes centrally; with unilateral conductive loss it tends to
lateralize toward the affected ear, while unilateral sensorineural loss tends to lateralize toward the better-hearing ear.
Vertigo: Distinguish a vestibular complaint (spinning/motion illusion) from presyncope or nonspecific imbalance. Vertigo plus
neurologic findings such as diplopia, severe ataxia, dysarthria, or focal weakness should raise concern for a central
neurologic process rather than being assumed to be an uncomplicated peripheral ear disorder.
3. Eye & Vision Assessment
Snellen: 20/20 is standard reference acuity. A 20/200 result means the patient sees at 20 feet what a person with standard
acuity can see at 200 feet. Sudden vision change warrants prompt assessment; legal-blindness definitions depend on
jurisdiction and the better eye after correction, so use the current standard specified by the course or authority.
Refractive errors: myopia = near objects clearer than distant; hyperopia = difficulty with near vision, especially as
accommodation is taxed; presbyopia = age-related loss of near focusing; astigmatism = irregular refractive curvature
producing blurred/distorted vision.
CN III: major roles include eyelid elevation, pupil constriction, and most extraocular movements. A significant CN III palsy
can cause ptosis, diplopia, an abnormal pupil, and impaired eye movements.
CN IV: innervates superior oblique; deficits classically impair depression of the adducted eye and can cause vertical
diplopia.
CN VI: innervates lateral rectus; a deficit impairs abduction.

, Conjugate gaze: both eyes move together in the same direction.
• Miosis = pupil constriction; mydriasis = pupil dilation.
• Anisocoria = unequal pupil size.
• A tonic pupil may have a poorly reactive pupil with characteristic accommodation findings.
• Horner syndrome classically involves miosis, mild ptosis, and decreased facial sweating on the affected side.
• Acute angle-closure glaucoma is an ocular emergency pattern: severe eye pain, cloudy cornea, headache/nausea, and a
mid-dilated or poorly reactive pupil can occur.
• Flashes and new floaters, especially with a curtain/shadow, raise concern for retinal tear/detachment and need urgent
ophthalmic evaluation.
4. Fundus & Retinal Findings
• Optic atrophy appears pale because of loss of optic nerve fibers.
• Retinal microaneurysms are small, round red lesions and are classically associated with diabetic retinopathy.
• Drusen are yellow deposits beneath the retina and are associated with age-related macular degeneration.
• AV crossing changes can be associated with chronic vascular disease; interpret the exact described finding carefully rather
than relying on a memorized phrase.
• Vitreous floaters can appear as moving spots or strands in the visual field. New sudden floaters/flashes are more
concerning than longstanding stable floaters.
Exam strategy: When a vignette gives eye pain + pupil abnormality + cloudy cornea, think emergency first. When it gives
sudden painless flashes/floaters, think posterior-segment pathology. When it gives gradual central visual distortion in an
older adult, consider macular disease.
5. Oral, Pharyngeal & Neck Assessment
• Stensen (parotid) duct opens on the buccal mucosa opposite the upper second molar.
• The submandibular ducts open near the lingual frenulum on the floor of the mouth.
• Leukoplakia is a white oral plaque that cannot simply be dismissed as normal; persistent lesions require evaluation
because some represent potentially premalignant change.
• Aphthous ulcers are typically discrete, painful, round/oval lesions with an erythematous border.
• Gingivitis produces inflamed, erythematous, swollen or bleeding gingiva.
• Inspect the tongue for symmetry, lesions, color, mobility, and deviation; tongue movement is primarily mediated by CN XII.
• When assessing the thyroid, use inspection and palpation systematically and note enlargement, nodules, tenderness,
mobility, and associated cervical findings.
• A persistent neck mass, unexplained oral lesion, or concerning lymphadenopathy requires appropriate follow-up rather
than reassurance based on appearance alone.
Common pediatric clue: developmental communication concerns should be evaluated in context of age, hearing, language
exposure, and developmental history. Do not assume a single isolated behavior establishes a diagnosis.
6. Nose & Sinus Assessment
• Inspect the septum for deviation, inflammation, perforation, crusting, bleeding, and lesions.
