JBL MODULE 3 EXAM PREP 2026 KEY
TOPICS AND LEARNING OUTCOMES
OVERVIEW
◉ CPAP is indicated for patients who:
A. have signs of pneumonia but are breathing adequately.
B. are unresponsive and have signs of inadequate ventilation.
C. have pulmonary edema and can follow verbal commands.
D. are hypotensive and have a marked reduction in tidal volume.
Answer: C. have pulmonary edema and can follow verbal commands.
◉ During your assessment of a patient with respiratory distress, you
hear wheezing when listening to breath sounds. This indicates:
A: swelling of the upper airway.
B: secretions in the airway
C: a lower airway obstruction
D: fluid in the alveoli
Answer: C: a lower airway obstruction
◉ Each cell of the body combines nutrients and oxygen and
produces energy and waste products through a process called:
,A: respiration
B: metabolism
C: ventilation
D: oxygenation
Answer: B: metabolism
◉ For which of the following conditions would the EMT most likely
administer humidified oxygen?
A: Hypoxia
B: Apnea
C: blood loss
D: croup
Answer: D: croup
◉ How does CPAP improve oxygenation and ventilation in patients
with certain respiratory problems?
A: it pushes thick, infected pulmonary secretions into isolated areas
of the lung.
B: it prevents alveolar collapse by pushing air into the lungs during
inhalation.
C: it forces the alveoli open and increases the concentration of
oxygen in the alveoli.
, D: it decreases intrathoracic pressure, which allows more room for
lung expansion
Answer: C: it forces the alveoli open and increases the concentration
of oxygen in the alveoli.
◉ How does positive-pressure ventilation affect cardiac output?
A: it increases intrathoracic pressure, which decreases venous
return to the heart and causes a decrease in cardiac output.
B: it causes pressure in the chest to decrease, which increases stroke
volume and cardiac output.
C: It decreases intrathoracic pressure, which facilities venous return
to the heart and increases cardiac output.
D: There is no effect on cardiac output because positive-pressure
ventilation is the act of normal breathing.
Answer: A: it increases intrathoracic pressure, which decreases
venous return to the heart and causes a decrease in cardiac output.
◉ Hypoxia is MOST accurately defined as:
A: a decrease in arterial oxygen levels
B: high oxygen levels in the tissues and cells
C: inadequate oxygen to the tissues and cells.
D: an increase in carbon dioxide in the blood
Answer: C: inadequate oxygen to the tissues and cells.
