NUR 101 EXAM 3 QUESTIONS WITH CORRECT
ANSWERS 2025/2026
Gas Exchange - CORRECT ANSWER -the process by which O2 is transported into the body & CO2
is transported out
Populations at risk for gas exchange - CORRECT ANSWER -Premature infants
Young children
Older adults
Individual risk factors (gas exchange) - CORRECT ANSWER -Age, allergies, air pollution
smoking, cystic fibrosis, COPD, heart failure, immunocompromised, sedentary lifestyle
Ventilation - CORRECT ANSWER -the act of inhaling and exhaling
Transport - CORRECT ANSWER -hemoglobin's ability to carry O2 from alveoli to cells for
metabolism & carry CO2 out
Perfusion - CORRECT ANSWER -the ability of blood to transport O2-containing hemoglobin to
cells & return CO2-containing HGB to the alveoli
Atelectasis - CORRECT ANSWER -collapsed lung; incomplete expansion of alveoli
Apnea - CORRECT ANSWER -absence of breathing
Hypoxia - CORRECT ANSWER -lack of oxygen
,Hyperventilation - CORRECT ANSWER -increased rate and depth of breathing

completely, slowly inhale deeply with spirometer in mouth, hold breath for 10 seconds, slowly
exhale. Repeat 10 times.

no smoking within 5ft
pressure ulcers
vesicular - CORRECT ANSWER -the soft, low-pitched, normal breath sounds heard over
peripheral lung fields
Inspiration > Expiration
diminished lung sounds - CORRECT ANSWER -decreased breath sounds with shallow breathing
, bronchovesicular - CORRECT ANSWER -the normal breath sound heard over major bronchi,
between scapula & below clavicles, characterized by moderate pitch
Inspiration = Expiration
bronchial - CORRECT ANSWER -normal breath sounds heard over the trachea
inspiration is slightly
