EXAM QUESTIONS
QUESTION 1
At what age does hearing start to change?
CORRECT ANSWER
Age 30
RATIONALE: Hearing change typically occurs due to age-related decline in the auditory system, specifically the loss of
hair cells in the cochlea and the degeneration of the auditory nerve, which starts to happen around the age of 30. This
gradual decline in hearing sensitivity and sound processing ability is a natural consequence of aging, making 30 a
significant milestone in the onset of age-related hearing changes.
QUESTION 2
Which of the following are normal hearing changes as an individual ages?
CORRECT ANSWER
Delayed reception and reaction to speech
Trusted by thousands of students and professionals worldwide Page 1 of 27
, RATIONALE: As individuals age, their ability to process auditory information can slow down due to age-related changes
in the brain, leading to delayed reception and reaction to speech. This delay is a natural consequence of declining
cognitive processing speed and efficiency, which affects how quickly the brain can interpret and respond to auditory
stimuli.
QUESTION 3
what affects conductive hearing loss
CORRECT ANSWER
Cerumen build up in the ear
RATIONALE: Cerumen build up in the ear is a correct answer to the question because it directly affects the outer ear and
ear canal, which are critical components of the conduction pathway for sound waves to reach the eardrum. When
cerumen accumulates, it can block or impede sound waves from reaching the eardrum, resulting in conductive hearing
loss due to the obstruction.
QUESTION 4
Which of the following reflects sensorineural hearing loss?
CORRECT ANSWER
Loud noise exposure
RATIONALE: Loud noise exposure leads to sensorineural hearing loss because it damages the hair cells in the inner ear,
which are responsible for converting sound vibrations into electrical signals and transmitting them to the brain. This type
of damage is irreversible and results in permanent sensorineural hearing loss.
QUESTION 5
Which of the following represents the ability to receive and interpret sensory impressions through
sight (visual), hearing (auditory), touch (tactile), smell (olfactory), taste (gustatory), and movement
or position (kinesthetic)?
CORRECT ANSWER
sensory perception
RATIONALE: Sensory perception involves the integration of various senses, including visual, auditory, tactile, olfactory,
gustatory, and kinesthetic, to create a comprehensive understanding of one's environment. This process allows
individuals to receive and interpret sensory impressions, enabling them to navigate and interact with their surroundings
in a meaningful way.
QUESTION 6
presbyopia
CORRECT ANSWER
farsightedness caused by loss of elasticity of the lens of the eye, occurring typically in middle and old age.
A gradual decline in the ability of the lens to accommodate or focus on close objects. Individual is unable
to see near objects clearly.
Trusted by thousands of students and professionals worldwide Page 2 of 27
, RATIONALE: Presbyopia is correct because it accurately describes a condition that occurs with age, specifically a decline
in the lens's ability to focus on close objects due to loss of elasticity. This description matches the normal definition of
presbyopia, which is a natural age-related reduction in the eye's lens flexibility, leading to farsightedness.
QUESTION 7
cataract
CORRECT ANSWER
Cloudy or opaque areas in part of the lens or the entire lens that interfere with passage of light through
the lens, causing problems with glare and blurred vision. Cataracts usually develop gradually, without
pain, redness, or tearing in the eye.
RATIONALE: The correct answer is based on the precise definition of a cataract, which involves a specific medical
condition that affects the lens of the eye. By accurately describing the symptoms and characteristics of cataracts, the
answer demonstrates a thorough understanding of the term's meaning and application in medical contexts.
QUESTION 8
glaucoma
CORRECT ANSWER
A slowly progressive increase in intraocular pressure that, if left untreated, causes progressive pressure
against the optic nerve, resulting in peripheral visual loss, decreased visual acuity with difficulty adapting
to darkness, and a halo effect around lights.
RATIONALE: This description accurately defines glaucoma because it specifically references the hallmark symptoms of
the disease, including increased intraocular pressure and its consequences on the optic nerve and vision, which are
directly related to the definition of glaucoma. The description highlights the key pathophysiological effects of glaucoma,
making it a comprehensive and precise definition of the condition.
QUESTION 9
diabetic retinopathy
CORRECT ANSWER
Pathological changes occur in the blood vessels of the retina, resulting in decreased vision or vision loss
caused by hemorrhage and macular edema.
RATIONALE: Diabetic retinopathy develops due to the damage diabetes causes to blood vessels in the retina, leading to
changes in their structure and function, which impacts vision. This vascular damage results in complications such as
hemorrhage and macular edema, directly contributing to decreased vision or vision loss.
QUESTION 10
macular degeneraion
CORRECT ANSWER
Condition in which the macula (specialized part of the retina responsible for central vision) loses its ability
to function efficiently. First signs include blurring of reading matter, distortion or loss of central vision, and
distortion of vertical lines.
