100% ACCURATE ANSWERS
Regular and prolonged exposure to loud sounds. These sounds do not necessarily have to be unpleasant
- for example, exposure to loud music can be just as harmful as exposure to loud machinery. Even short
term exposure to loud sound can cause temporary deafness.
Ototoxic drugs - some medicines are harmful to the cochlea and/or hearing nerve. These include drugs
that are used in the treatment of serious diseases such as cancer but also include certain types of
antibiotics
Certain infectious diseases, including Rubella
Complications at birth
Injury to the head
Benign tumours on the auditory nerve - although rare, these can cause hearing loss
Genetic predisposition - some people are especially prone to hearing loss.
Sensorineural hearing loss not only changes our ability to hear quiet sounds, but it also reduces the
quality of the sound that is heard, meaning that individuals with this type of hearing loss will often
struggle to understand speech. Once the cochlea hair cells become damaged, they will remain damaged
for the rest of a person's life. Therefore sensorineural hearing loss is irreversible and cannot be cured -
at least at the present time.
Claudication - correct answersa condition in which cramping pain in the leg is induced by exercise,
typically caused by obstruction of the arteries. May be characterized as a dull ache with accompanying
muscle fatigue and cramps. Usually appears with sustained exercise. Site of pain is distant to narrowing.
How do you test EOM? - correct answersEye movement is controlled by 6 extraocular muscles and 3
cranial nerves, III, IV, and VI. To evaluate eye movement, use 4 techniques.
● First have the patient watch your finger move through the 6 cardinal fields of gaze. Jerking or
sustained nystagmus is abnormal. A few beats of horizontal nystagmus may occur.
● Second have the patient follow your finger vertically from the ceiling to the floor.The globes and the
upper eyelids should move smoothly without eyelid lag or exposure of the sclera.
● Third, test extraocular muscle balance using the corneal light reflex. WIth the patient looking at a
nearby object, shine a light on the nasal bridge. The eyes should converge and reflect the light
symmetrically.
, ● Fourth, if the corneal light reflex is imbalanced, perform the cover-uncover test. As the patient stares
at a fixed point nearby, cover one eye and observe the uncovered eye. Then remove the cover and
observe that eye as it focuses on the object. Note any eye movement.
Your patient should be able to follow your finger with full, smooth extraocular movements and without
nystagmus, or "shaky" eye motion. Normal extraocular movements indicate intact cranial nerves III, IV,
and VI.
*******What is the difference between objective and subjective data? What components of the health
history are objective and subjective? *********** - correct answersSeidel pg 618: objective: "direct
observation, what you see, hear, and touch". This includes vital signs and actual assessment. Subjective:
"information patients offer about their condition or feelings." This includes chief complaint, past medical
history, history or present illness, family history, and review of symptoms.
Erb's point - correct answersErb's point is the auscultation location for heart sounds and heart murmurs
located at the third intercostal space and the left lower sternal border. Erb's point, found two
interspaces below the pulmonic area, does not reflect sound from one particular heart valve, but is a
common listening post, lying halfway between the base and the apex of the heart.
Tonsil assessment - correct answers• Enlargement; Acute infection, 2+, 3+, or 4+
o 1+ - visible
o 2+ halfway between tonsillar pillars
o 3+ touching uvula
o 4+ touching each other
Order physical assessment is done - correct answersInspection, Palpation, Percussion, Auscultation
Proper use of Otoscope on adult or child - correct answersAdult- straighten the external auditory canal
by pulling auricle up and back
Child- face child sideways with one arm around parents waist. Pull auricle either downward and back or
upward and back to gain best view of tympanic membrane.
How do you assess for sensoineural hearing loss - correct answersair conduction heard longer than bone
conduction with Rinne Test; lateralization to unaffected ear; loss of high-frequency sounds
