LESS STRESS - Mod 2 Exam Questions Answered Correctly Latest Update 2025-2026
List the parts of the airway in order starting at the mouth and nose - what does each part do? -
Answers 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? - Answers bronchi and bronchioles
glottis - Answers Opening between vocal cords which allows for sound to leave the larynx
partial pressure - Answers Amount of gas in air or dissolved in fluid, such as blood
psi - Answers pounds per square inch, measure of pressure such as in an oxygen tank
ventilation vs respiration - Answers 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? - Answers 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? - Answers the
tongue falling back and covering the airway
What chemical change in your blood stream makes you want to take a breath? - Answers the
chemoreceptors detect high CO2 levels and signal the brain, pH of CSF decreases due to
increased acidity of the blood
hypoxic drive - Answers 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 - Answers - 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 - Answers Deep, rapid breathing; usually the result of an accumulation of
certain acids when insulin is not available in the body.
gurgling - Answers - sounds like bubbles
- indicates presence of fluid in the upper airway
- need for suctioning (usually AMS pt)
snoring - Answers 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 - Answers - 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 - Answers - 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 - Answers - 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? - Answers 2000 psi = full pressure
