FISDAP AIRWAY EXAM ACTUAL 110 EXAM
NEWEST VERSION 2024-2025 EXPECTED QUESTION
AND CORRECT ANSWER FROM VERIFIED SOURCES
RATED A GRADE.
What is hypoxic drive? ✔✔CORRECT ANSWER✔✔Backup system to
control respiration. Chemoreceptors in brain, aorta, and carotid
arteries. But they are "satisfied" by a small amount of O2, which means
it is not as sensitive as pH control of CO2
What two areas of the brain are involved in respiration? ✔✔CORRECT
ANSWER✔✔medulla-controls rhythm, initiates inspiration, sets base
pattern for respirations, and stimulates diaphragm to contract.
pons-changes depth of inspiration, expiration or both.
True or false: arteries bring oxygenated blood to organs/capillaries
✔✔CORRECT ANSWER✔✔True in most cases with one exception.
Arteries (away) bring blood away from the heart. Usually this is
oxygenated blood. But the pulmonary arteries bring oxygen poor blood
away from the heart, to the lungs to be oxygenated.
What is the tidal volume? ✔✔CORRECT ANSWER✔✔amount of air
moved in/out of lungs in single breath. Usually 500 ml in adult
,What is inspiratory reserve volume? ✔✔CORRECT ANSWER✔✔Deepest
breath you can take after normal respiration
What is expiratory reserve volume/Vital Capacity? ✔✔CORRECT
ANSWER✔✔maximum amount you can breathe out after normal
breath.
What is residual volume? ✔✔CORRECT ANSWER✔✔Remaining gas in
lungs after exhalation. This is to keep lungs inflated
What is dead space? What structures are considered part of dead
space? ✔✔CORRECT ANSWER✔✔Part of respiratory system not
involved in active respiration. Air moves through here but little to no
respiration occurs. Mouth, trachea, bronchi and bronchioles considered
dead space
What is minute volume? What does it measure? ✔✔CORRECT
ANSWER✔✔Minute volume = RR x tidal volume. Volume of air moving
through lungs in 1 minute. Can be estimated quickly. Count RR rate. If
normal check to see chest rise and fall (tidal volume). If chest rise and
fall is weak and/or little air coming out of nose, then the person has
small minute volume.
,Alveolar Minute Volume ✔✔CORRECT ANSWER✔✔Volume of air
moved through lungs in 1 minute minus the dead space. Alveolar
Minute Volume = (tidal volume - dead space) x RR
Alveolar Ventilation ✔✔CORRECT ANSWER✔✔Volume of air that
reaches alveoli.
Alveolar ventilation = tidal volume - dead space
Name the characteristics of normal breathing ✔✔CORRECT
ANSWER✔✔1. Normal rate (12-20)
2. regular pattern of inhalation/exhalation
3. clear bilateral lung sounds
4. regular and equal chest rise/fall
5. adequate depth (tidal volume)
What are the characteristics of inadequate breathing (adults)?
✔✔CORRECT ANSWER✔✔Chapter 6
1. labored breathing (activating accessory muscles of respiration)
2. 12< or >20 breaths/minute
3. muscle retractions above clavicles or between ribs and below rib cage
4. pale/cyanotic skin
5. cool, damp, clammy skin
, 6. tripod position
Chapter 10
1. 12< or 20>
2. irregular rhythm
3. diminished, absent or noisy auscultated breath sounds
4. reduced flow of expired air at nose/mouth
5. unequal or inadequate chest expansion
6. labored breathing
7. shallow depth
8. pale, cyanotic, cool or moist skin
9. retractions around ribs or above clavicles
What are agonal gasps? What should you do if a pt has agonal gasps?
✔✔CORRECT ANSWER✔✔Pt in cardiac arrest has occasional gasping
breaths because respiratory center in brain continues to send signals to
breathing muscles. Artificial ventilations and chest compressions.
Where are the alpha-1 receptors located? What is their effect?
✔✔CORRECT ANSWER✔✔location-blood vessels
constricted blood vessels, skin is pale, cool, clammy
