WEEK 1 FNP SEM 2 26 STUDYGUIDE QUESTIONS AND CORRECT ANSWERS
Question:
1. Mucociliary Clearance
Answer:
The process where cilia move mucus containing trapped particles toward the throat to be
swallowed.
Question:
2. Epiglottis Function
Answer:
Closes the airway during swallowing to prevent food and liquid from entering the lungs.
Question:
3. Right vs. Left Lung Anatomy
Answer:
The right lung has 3 lobes; the left lung has 2 lobes to accommodate the heart.
Question:
4. Pulmonary Blood Vessels Function
Answer:
Pulmonary arteries carry deoxygenated blood to lungs; pulmonary veins return oxygenated blood
to the heart.
Question:
5. Primary Gas Exchange Location
Answer:
Alveoli, surrounded by capillaries, where O₂ and CO₂ diffuse across thin walls.
Question:
6. Gas Exchange Concentration Gradient
Answer:
O₂ diffuses into blood (higher in alveoli); CO₂ diffuses into alveoli (higher in blood).
Question:
7. Intercostal Muscle Action in Breathing
Answer:
Lifts ribs/sternum, increasing chest volume and creating negative pressure to draw air in.
Question:
8. Diaphragm Action during Inhalation
Answer:
Contracts and moves downward, expanding the lungs to draw air in.
, Question:
9. Visceral vs. Parietal Pleura
Answer:
Visceral pleura covers the lungs; parietal pleura lines the chest wall.
Question:
10. Asthma Definition
Answer:
A chronic inflammatory lung disease causing airway narrowing, hyperresponsiveness, and
breathing difficulty.
Question:
11. Three Causes of Airway Narrowing in Asthma of Asthma
Answer:
Bronchoconstriction (muscle tightening), airway lining swelling (oedema), and excess mucus
production. e80%
Question:
12. Mild Intermittent Asthma Criteria
Answer:
Symptoms <2x/week, nighttime <2x/month, and lung function predicted. e80%
Question:
13. Mild Persistent Asthma Criteria
Answer:
Symptoms 3-6x/week, nighttime 3-4x/month, and lung function predicted. e5x/month,
Question:
14. Moderate Persistent Asthma Criteria
Answer:
Daily symptoms, nocturnal symptoms and lung function 60-80% predicted.
Question:
15. Severe Persistent Asthma Criteria
Answer:
Continuous symptoms, frequent nighttime flare-ups, limited activity, and lung function <60%
predicted.
Question:
16. Childhood Asthma Gender Prevalence
Answer:
More common in boys than girls until puberty, likely due to smaller airway size.
