Questions with solutions
Q1 — Respiratory Volumes & Capacities · easy · theory
The volume of air inspired or expired during a normal quiet breath (about 500 mL) is the:
A. Vital capacity
B. Residual volume
C. Tidal volume (TV) ✓ Correct
D. Inspiratory reserve volume
Solution: Tidal volume (~500 mL) is the air moved per normal breath.
Q2 — Respiratory Volumes & Capacities · easy · theory
The volume of air remaining in the lungs even after a forcible expiration is the:
A. Inspiratory reserve volume
B. Residual volume (RV) ✓ Correct
C. Tidal volume
D. Expiratory reserve volume
Solution: Residual volume (~1100–1200 mL) cannot be expelled and keeps the alveoli inflated.
Q3 — Respiratory Volumes & Capacities · medium · theory
Vital capacity (VC) is the sum of:
A. ERV + TV + IRV (the maximum air that can be breathed out after maximum inspiration) ✓ Correct
B. IRV + RV
C. TV + RV
D. RV + ERV
Solution: Vital capacity = ERV + TV + IRV — the maximum volume exchangeable with maximal effort.
Q4 — Respiratory Volumes & Capacities · medium · theory
The total lung capacity is the sum of the vital capacity and the:
A. Inspiratory reserve volume
B. Residual volume ✓ Correct
C. Expiratory reserve volume
D. Tidal volume
Solution: Total lung capacity = VC + RV (total air the lungs can hold at maximum inflation).
Q5 — Respiratory Volumes & Capacities · hard · theory
Functional Residual Capacity (FRC) — the volume of air remaining in the lungs after a normal expiration — equals:
A. VC + RV
B. ERV + RV ✓ Correct
C. IRV + ERV
D. TV + IRV
Solution: FRC = Expiratory Reserve Volume + Residual Volume.
Q6 — Respiratory Volumes & Capacities · hard · theory
Inspiratory Capacity (IC), the total volume a person can inspire after a normal expiration, is:
A. ERV + RV
B. IRV + RV
C. TV + ERV
D. TV + IRV ✓ Correct
Solution: Inspiratory Capacity = Tidal Volume + Inspiratory Reserve Volume.
