Portage Pathophysiology Module 5 Exam 2026 |Questions &
Verified Answers | Latest Update | Graded A+
1. The ease at which the lungs expand on inspiration is called
compliance.
inflation.
ventilation.
surfactant.
elasticity.
2. What is a characteristic feature of chronic bronchitis that distinguishes it from
other respiratory conditions?
Shortness of breath
Barrel chest
Wheezing
Chronic cough and sputum production
3. What is COPD characterized by?
Chronic inflammation and irreversible airflow limitation
Acute bronchospasms
Increased lung compliance
Rapid lung tissue regeneration
4. Which of the following is a common characteristic associated with asthma?
Airway hyperresponsiveness
, Hypertrophy of the submucosal glands
Pulmonary fibrosis
Decreased lung volumes
5. When a portion of a clot travels through the bloodstream, lodges in a narrow
artery, and causes sudden tissue death, it is called a(n) .
platelet
thrombus
embolism
aneurysm
6. If a patient with COPD experiences an exacerbation, which of the following
symptoms would you expect to worsen?
Improved oxygen saturation
Decreased heart rate
Shortness of breath
Increased lung capacity
7. Describe how increased carbon dioxide concentration affects hemoglobin's
ability to bind oxygen.
Increased carbon dioxide concentration has no effect on
hemoglobin's affinity for oxygen.
Increased carbon dioxide concentration lowers hemoglobin's
affinity for oxygen, promoting oxygen release to tissues.
Increased carbon dioxide concentration causes hemoglobin to bind
to carbon dioxide instead of oxygen.
, Increased carbon dioxide concentration increases hemoglobin's
affinity for oxygen, enhancing oxygen uptake.
8. What is the term that refers to the ease of lung inflation?
Ventilation
Resistance
Perfusion
Compliance
9. The nurse should teach the parents of a 6-year-old recently diagnosed with
asthma that the symptoms of an acute episode of asthma are due to which
physiological response?
Inflammation of the mucous membranes and bronchospasm
Thickening of the alveoli inhibiting O2 and CO2 exchange
Neurological response inhibiting breathing and respiratory rate
Anxiety causing hyperventilation and shallow breathing
10. Describe how a thrombus can lead to respiratory complications in patients
with existing lung conditions.
A thrombus has no effect on respiratory conditions.
A thrombus only affects the heart, not the lungs.
A thrombus can obstruct blood flow to the lungs, leading to
decreased oxygenation and respiratory distress.
A thrombus can enhance blood flow, improving lung function.
11. Which of the following is not a sign or symptom of emphysema?
lungs remain expanded even after exhalation
