1. A patient complains of a sore tongue. Findings reveal a smooth and erythematous
tongue. This condition is termed:
A. gingivitis.
B. stomatitis.
C. glossitis.
D. candidiasis.
ANSWER: C. glossitis.
Explanation: Glossitis refers to inflammation of the tongue, leading to a smooth, red, and often
sore appearance. It can result from nutritional deficiencies (e.g., B12, iron), infections, or
irritants.
2. A condition that involves optic nerve damage and visual field changes is termed:
A. retinoblastoma.
B. cataracts.
C. glaucoma.
D. pterygium.
ANSWER: C. glaucoma.
Explanation: Glaucoma is characterized by increased intraocular pressure, leading to optic nerve
damage and progressive vision loss, often with peripheral visual field defects.
3. Ophthalmoscopic examination of the fundus reveals small, rounded, slightly irregular
red spots embedded in the retina. These findings are consistent with:
A. superficial retinal hemorrhages.
B. preretinal hemorrhages.
C. microaneurysms.
, D. deep retinal hemorrhages.
ANSWER: D. deep retinal hemorrhages.
Explanation: Deep retinal hemorrhages appear as small, rounded, red spots ("dot-blot"
hemorrhages) and are commonly seen in diabetic retinopathy or hypertensive retinopathy.
4. A cyclist sustained an avulsion of the upper central incisor. If he is unable to position the
tooth in the socket until he is able to be seen by a dentist, he should:
A. transport the tooth in a cup of lukewarm tap water.
B. place the tooth between the molars and the inside of the cheek.
C. rinse the tooth and transport it in a clean dry cloth.
D. not rinse the tooth but transport it in a clean dry cloth.
ANSWER: B. place the tooth between the molars and the inside of the cheek.
Explanation: The best way to preserve an avulsed tooth is to keep it moist in saliva (cheek
pouch) or milk. Avoid tap water, which can damage the periodontal ligament cells needed for
reimplantation.
5. A condition in which the eyes are not properly aligned with each other is termed:
A. hyperopia.
B. myopia.
C. strabismus.
D. astigmatism.
ANSWER: C. strabismus.
Explanation: Strabismus is misalignment of the eyes, where one eye may turn inward
(esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia).
6. Findings following assessment of a person's left eye gaze include impaired movements
when attempting to look upward, downward, or inward. This condition is most consistent
with:
A. a conjugate gaze.
B. left cranial nerve III (oculomotor) paralysis.
C. cranial nerve IV (trochlear) paralysis.
D. cranial nerve VI (abducens) paralysis.
, ANSWER: B. left cranial nerve III (oculomotor) paralysis.
Explanation: CN III (oculomotor) controls most extraocular movements (except lateral rectus
and superior oblique). Damage leads to ptosis, pupil dilation, and impaired upward, downward,
and inward gaze.
7. On ophthalmoscopic exam of the older adult, there is an increased cup-to-disc ratio. This
finding is suggestive of:
A. cataracts.
B. macular degeneration.
C. open-angle glaucoma.
D. blindness.
ANSWER: C. open-angle glaucoma.
Explanation: An increased cup-to-disc ratio (>0.5) indicates optic nerve damage due to
glaucoma, where increased intraocular pressure leads to progressive vision loss.
8. Mydriasis is a term used to describe:
A. the shape of the pupils.
B. constriction of the pupils.
C. dilation of the pupils.
D. symmetry of the pupils.
ANSWER: C. dilation of the pupils.
Explanation: Mydriasis refers to pupil dilation, which can occur due to drugs (e.g., atropine),
trauma, or neurological conditions.
9. To palpate for sinus tenderness, press up on the frontal sinuses from under the bony
brows, then:
A. press down on the ethmoid sinus.
B. press up on the maxillary sinus.
C. palpate around the orbit.
D. observe the turbinates.
