1. Which of the following best defines the primary role of the
respiratory therapist in patient care?
A) To independently diagnose all pulmonary diseases without physician
consultation.
B) To administer medications and manage ventilators exclusively in the
intensive care unit.
C) To evaluate, treat, and care for patients with breathing or other
cardiopulmonary disorders under medical direction.
D) To perform only diagnostic testing such as pulmonary function tests
and arterial blood gas analysis.
Answer: C
Explanation: The respiratory therapist's role is comprehensive and
involves evaluation, treatment, and care of cardiopulmonary patients.
This is always performed under qualified medical direction, making
option C the most accurate. Options A, B, and D are incorrect because
they either overstate the RT's autonomy (A) or limit the scope of
practice to specific settings or tasks (B and D).

2. The process of oxygenation involves which of the following?
A) The movement of air into and out of the lungs.
B) The transport of carbon dioxide from the tissues to the lungs.
C) The loading of oxygen onto hemoglobin in the pulmonary capillaries.
D) The exchange of gases between the blood and the tissues.
Answer: C
Explanation: Oxygenation specifically refers to the process of adding
oxygen to the blood, primarily through its binding to hemoglobin in the
pulmonary capillaries. Ventilation is the movement of air (A). Carbon
dioxide transport (B) and internal respiration (D) are related but distinct
processes.
3. Ventilation is best described as:
A) The movement of oxygen from the alveoli into the blood.
B) The mechanical process of moving air into and out of the lungs.
C) The exchange of gases across the respiratory membrane.
D) The transport of respiratory gases in the bloodstream.
Answer: B
Explanation: Ventilation is the bulk flow of air or gas into and out of the
lungs. Option A describes diffusion or oxygenation. Option C describes
external respiration. Option D describes gas transport.
4. An adult patient has a tidal volume of 500 mL and a respiratory rate
of 12 breaths/min. What is the minute ventilation?
,3|Page
A) 4 L/min
B) 6 L/min
C) 8 L/min
D) 10 L/min
Answer: B
Explanation: Minute ventilation (VE) is the total volume of gas inhaled
or exhaled per minute. It is calculated as Tidal Volume (VT) x
Respiratory Rate (RR). 0.5 L (500 mL) x 12 breaths/min = 6 L/min.
5. Alveolar ventilation differs from minute ventilation because it:
A) Includes the volume of air in the conducting airways.
B) Is the total amount of gas reaching the alveoli per minute.
C) Is calculated using the dead space volume.
D) Both B and C.
Answer: D
Explanation: Alveolar ventilation (VA) is the volume of gas that reaches
the alveoli per minute and is available for gas exchange. It is calculated
as (VT - Dead Space) x RR. Therefore, it accounts for dead space (C) and
is the volume reaching the alveoli (B). Option A is incorrect because
alveolar ventilation excludes the volume in the conducting airways.
6. Anatomic dead space is best defined as:
A) Alveoli that are ventilated but not perfused.
, 4|Page
B) The volume of gas in the conducting airways that does not
participate in gas exchange.
C) Alveoli that are perfused but not ventilated.
D) The total volume of gas exhaled in one minute.
Answer: B
Explanation: Anatomic dead space refers to the volume of the
conducting airways (nose, pharynx, trachea, bronchi) where no gas
exchange occurs. Option A describes alveolar dead space. Option C
describes shunt. Option D is minute ventilation.
7. Which of the following structures is NOT considered part of the
conducting zone?
A) Trachea
B) Terminal bronchiole
C) Respiratory bronchiole
D) Mainstem bronchus
Answer: C
Explanation: The conducting zone includes the airways from the
nose/mouth down to the terminal bronchioles. The respiratory zone,
where gas exchange begins, includes the respiratory bronchioles,
alveolar ducts, and alveoli.
8. The respiratory membrane is composed of:
A) A single layer of epithelial cells.
