LESS STRESS - MOD 2 EXAM
QUESTIONS WITH VERIFIED
ANSWERS. A+ GRADE 2025/2026.
List the parts of the airway in order starting at the mouth and nose - what does each part do? -
ANS 1) nose/mouth
2) pharynx (nasopharynx/oropharynx/laryngopharynx)
3) epiglottis - separates trachea and esophagus
4) larynx - barrier btwn upper and lower airway
5) trachea - voice box
6) bronchi - separates at carina
7) bronchioles
8) alveoli - gas exchange w/ capillaries
What structures constrict in an asthmatic or allergy patient? - ANS bronchi and bronchioles
glottis - ANS Opening between vocal cords which allows for sound to leave the larynx
partial pressure - ANS Amount of gas in air or dissolved in fluid, such as blood

,psi - ANS pounds per square inch, measure of pressure such as in an oxygen tank
ventilation vs respiration - ANS ventilation- the simple movement of air into and out of the
lungs
respiration- the exchange of gases between the lungs, the blood, and the tissues of the body
is exhalation a passive or active process? - ANS Exhalation = passive (lungs recoil as
respiratory muscles relax and thorax decreases in size)
Inhalation = active process!
What is the most common reason for air to be blocked when ventilating a patient? - ANS the
tongue falling back and covering the airway
What chemical change in your blood stream makes you want to take a breath? - ANS the
chemoreceptors detect high CO2 levels and signal the brain, pH of CSF decreases due to
increased acidity of the blood
hypoxic drive - ANS A "backup system" to control respiration; senses drops in the oxygen
level in the blood rather than high levels of carbon dioxide
Cheyne-Stokes respiration - ANS - pattern of breathing characterized by a gradual increase of
depth and sometimes rate to a maximum level, followed by a decrease, resulting in apnea
- usually found in pt with head injury
Kussmaul respirations - ANS Deep, rapid breathing; usually the result of an accumulation of
certain acids when insulin is not available in the body.

, gurgling - ANS - sounds like bubbles
- indicates presence of fluid in the upper airway
- need for suctioning (usually AMS pt)
snoring - ANS The sound of the soft tissue of the upper airway creating a partial obstruction
of air flow, can be caused by the tongue or tissues in other areas of the throat
wheezing - ANS - High pitched sound heard in the lungs with asthma, anaphylaxis, or lung
disease pts
- due to bronchoconstriction in the lower airway
- exhalations usually longer than inhalations
- intervene w/ oxygen, epi, albuterol depending on situation
rales/crackles - ANS - sounds like rice krispies
- due to air moving through fluid accumulations in the lungs such as subcutaneous emphysema
and CHF pts
- lower airway
- can be resolved with oxygen and possibly CPAP
Rhonchi - ANS - rattling noise that sounds like high pitched wheezing
- lower airway, when lungs are obstructed by material like mucus
- found in pt with respiratory infections and conditions like CF
- only heard in area of obstruction
- resolved with oxygen
What is the maximum/full PSI of most oxygen tanks? - ANS 2000 psi = full pressure
*can refill when below 1000, usually 500
