Where is the nerve center of the ear located?
The inner ear
When the nurse utilizing the Snellen chart. What 3 areas are being assessed?
1. Visual acuity (distance vision)
2. Color perception
3. depth perception
When assessing peripheral vision, the nurse is assessing for the presence of
blind spots which would suggest optic nerve damage (CN II) or glaucoma
What are the three expected breath sounds and where are they located?
1. Bronchial breath sounds are heard over the trachea
2. Broncho vesicular breath sounds-anteriorly these sounds are heard at ICS 1-2 and
posteriorly these sounds are heard at T4-T5
3. Vesicular breath sounds are heard over the peripheral lung lobes including axillary
area
What are adventitious breath sounds?
abnormal breath sounds
What is a wheeze and what causes this to occur?

are easily cleared upon coughing (check that the sound is not coming from clothing
or hair on the chest). Caused by thin fluid (mucous) moving over the alveoli
•Coarse crackles have a bubbling sound or , similar to carbonated soda or separating
Velcro).; and are not usually cleared with coughing. Caused by thick fluid (mucous)
