ANSWERS WITH RATIONALES
Question 1
Which of the following is most likely to be responsible for the transmission of
epidemic adenovirus keratoconjuctivitis
A. finger-to-eye transmission
B. applanation tonometry
C. fluorescein solutions
D kissing
Correct Answer
A. finger-to-eye transmission
The physician's office is the source of many epidemics of adenovirus infection.
Medical personnel who touch lids, conjunctiva and other ocular tissues must wash
their hands between patients when patients with ocular infections are examined.
Question 2
Washing hands between patients is an example of which of the following?
A. aseptic technique
B. disinfection
C. request of the physician
D. standard precaution
Correct Answer
D. standard precaution
A standard precaution in minimizing the spread of pathogens is for the medical
professional to wash their hands between patients.

,Question 3
The acronym CPR stands for
A. carotoidpulse reation
B. cardiopulmonary reflex
C. corneal pupillary reflex
D. Cardiopulmonary resuscitation
Correct Answer
D. Cardiopulmonary resuscitation
The acronym CPR stands for cardiopulmonary resuscitation
Question 4
A near visual acuity test determines the ability of the patient to see
A. the large E at a predetermined distance
B. the large E at normal distance
C. the specified M unit at a far point
D. the card clearly at a normal distance
Correct Answer
D. the card clearly at a normal distance
A near visual acuity test determines the ability of the patient to see clearly at a
normal reading distance. The near vision acuity test card provides for a choice of
recording notations based on various units of measurements, the most common are
the distance equivalent and Jaeger notations

,Question 5
The acronym RAPD stands for
A. removable anterior pupillary deposits
B. relative afferent pupillary defect
C. retro-aqueous pupil development
D. reasonably adapted pupil diameters.
Correct Answer
B. relative afferent pupillary defect
The acronym RAPD stands for relative afferent pupillary defect, a condition where
the pupil does not respond to direct stimulation of light
Question 6
Tonometry refers to the measurement of the eye's
A. pressure
B. vitreous
C. curvature
D. striations
Correct Answer
A. pressure
Tonometry refers to the measurement of the intraocular pressure within the eye.
Along with other test, it is a useful procedure in determining the possible presence
of glaucoma. There are three types of tonometers currently in use, applanation,
indentation and noncontact.

, Question 7
Inaccurate pressure readings when performing indention tonometry can be attributed
to the
A. corneal curvature
B. ocular rigidity
C. crystalline lens
D. extraocular muscles
Correct Answer
B. ocular rigidity
With indentation (Schiotz) tonometry, variation in ocular rigidity or scleral elasticity
could lead to an inaccurate pressure reading
Question 8
The partial or complete blindness within a normal visual field is known as a(n)
A. confrontation field
B. diplopia field
C. hemianopia
D. scotoma
Correct Answer
D. scotoma
A scotoma is an area of partial or complete blindness within a normal visual field.
