|/ |/ |/
1. A student nurse is explaining to a pt about the respiratory
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
system. Which statement by the student nurse would require
|/ |/ |/ |/ |/ |/ |/ |/ |/
correction from the clinical instructor?
|/ |/ |/ |/ |/
a. Neural & chemical regulators control the rate and depth of
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
respiration in response to changing tissue O2 demands.
|/ |/ |/ |/ |/ |/ |/ |/ |/
b. The respiratory system is the system responsible for supplying
|/ |/ |/ |/ |/ |/ |/ |/ |/
O2 to the rest of the body.
|/ |/ |/ |/ |/ |/ |/ |/
c. The exchange of respiratory gases occurs between the
|/ |/ |/ |/ |/ |/ |/ |/
environment and the blood.
|/ |/ |/ |/ |/
d. Respiration is the exchange of O2 and CO2 during cellular
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
metabolism. - CORRECT ANSWERS ✔✔B: Both the respiratory
|/ |/ |/ |/ |/ |/ |/ |/
and cardiac systems are responsible for supplying O2 to the rest

of the body.
|/ |/ |/
2. While doing a respiratory assessment on a pt. during clinical, a
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
student nurse notices that the pt. elevates his clavicles upon
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
inspiration. The student nurse knows that raised clavicles could
|/ |/ |/ |/ |/ |/ |/ |/ |/
indicate which of the following? SATA.
|/ |/ |/ |/ |/ |/ |/
a. Increased lung expansion
|/ |/ |/
b. Ventilatory fatigue
|/ |/ |/
c. Air hunger
|/ |/
d. Decrease in work of breathing - CORRECT ANSWERS ✔✔B & C:
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
Elevation of the clavicles upon inspiration can indicate
|/ |/ |/ |/ |/ |/ |/ |/
ventilatory fatigue, air hunger, or decreased lunch expansion.
|/ |/ |/ |/ |/ |/ |/ |/
,3. A student nurse's pt is immobile. She knows that her pt is
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
mainly at risk for which respiratory event?
|/ |/ |/ |/ |/ |/ |/
a. Increased work of breathing
|/ |/ |/ |/
b. Decreased surfactant
|/ |/
c. Decreased compliance
|/ |/ |/
d. Atelectasis
|/ |/
e. Increased airway resistance - CORRECT ANSWERS ✔✔D:
|/ |/ |/ |/ |/ |/ |/
Atelectasis (collapse of the alveoli the prevents normal exchange
|/ |/ |/ |/ |/ |/ |/ |/ |/
of gases) is a major concern for immobile pts. The pt's work of
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
breathing (effort required to expand & contract the lungs) may
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
be increased, compliance (ability of the lungs to expand in
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
response to increase alveolar pressure) may be decreased, and
|/ |/ |/ |/ |/ |/ |/ |/ |/
airway resistance (increase in pressure that occurs as the
|/ |/ |/ |/ |/ |/ |/ |/ |/
diameter of airway decreases from nose/mouth to the alveoli)
|/ |/ |/ |/ |/ |/ |/ |/ |/
may be increased, but the main concern would be atelectasis.
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
Surfactant is the chemical produced in the lungs to maintain the
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
surface tension of the alveoli & keep them from collapsing;
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
surfactant dysfunction typically occurs in newborns & children.
|/ |/ |/ |/ |/ |/ |/ |/
4. Which of the following terms is matched correctly with its
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
definition? SATA.
|/ |/ |/
a. Ventilation: exchange of respiratory gases in the alveoli &
|/ |/ |/ |/ |/ |/ |/ |/ |/
capillaries
|/ |/
b. Perfusion: ability of the CVS to pump oxygenated blood to the
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
tissues & deoxygenated blood back to the lungs
|/ |/ |/ |/ |/ |/ |/ |/ |/
c. Inspiration: passive process; stimulated by chemical receptors
|/ |/ |/ |/ |/ |/ |/
in the aorta
|/ |/ |/
, d. Expiration: passive process; depends on elastic recoil of lungs
|/ |/ |/ |/ |/ |/ |/ |/ |/
& requires little to no muscle work - CORRECT ANSWERS ✔✔B &
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
D: Ventilation is the process of moving gases into and out of the
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
lungs. Diffusion is the exchange of respiratory gases in the
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
alveoli & capillaries (bc of concentration gradient). Inspiration is
|/ |/ |/ |/ |/ |/ |/ |/ |/
an active process, stimulated by chemical receptors in the aorta.
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/
5. What are the three steps in oxygenation?
|/ |/ |/ |/ |/ |/ |/
a. Inspiration, expiration, & ventilation
|/ |/ |/ |/ |/
b. Ventilation, perfusion, & diffusion
|/ |/ |/ |/
c. Compliance, airway resistance, & surfactant
|/ |/ |/ |/ |/
d. Ventilation, diffusion & expiration - CORRECT ANSWERS ✔✔B:
|/ |/ |/ |/ |/ |/ |/ |/
Ventilation, perfusion, & diffusion are the three steps in
|/ |/ |/ |/ |/ |/ |/ |/ |/
oxygenation.

6. Your pt is immobile and at risk for atelectasis. Which nursing
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
interventions should you implement in order to prevent alveolar
|/ |/ |/ |/ |/ |/ |/ |/ |/
collapse? SATA.
|/ |/ |/

|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
hour

|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
treatments must be ordered by the HCP and are typically given
|/ |/ |/ |/ |/ |/ |/ |/ |/ |/ |/
