NUR 211: Exam 1 Practice Questions and
Answers Latest Update 2024-2025
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.
ANS✔✔ 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 ANS✔✔ 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 ANS✔✔ 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 ANS✔✔ 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 ANS✔✔ 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.
a. Teach pt how to use an incentive spirometer 5-10 time every hour
b. Turn pt every three hours
c. Ambulate pts as soon as possible
d. Give the pt a nebulizer treatment PRN ANS✔✔ A & C: Pts should be
turned every two hours. Nebulizer treatments must be ordered by the HCP
and are typically given by the respiratory therapist, not the nurse.
7. Which factors affect respiratory gas exchange? SATA.
a. Thickness of the alveolar capillary membrane
b. Surface area of the Hgb
c. Blood capacity to carry O2
d. Forced vital capacity ANS✔✔ A & C: The surface areas of the alveoli
would affect gas exchange. Blood capacity to carry O2 is influenced by the
amount of O2 dissolved in the plasma, the amount of Hgb, & the ability of
the Hgb to bind with O2 and form reversible oxyHgb.
