Question

Pick the incorrect match.

• A. Tidal volume – 500 mL
• B. Inspiratory Reserve volume – 2,500 mL
• C. Residual volume – 1,200 mL
• D. Expiratory Reserve volume – 3,000 mL

Hint:

Typical respiratory volumes for adults are: Tidal volume (500 mL), Inspiratory Reserve (2,500–3,000 mL), Expiratory Reserve (1,000–1,200 mL), and Residual volume (1,200 mL).

Answer 1

The Correct Option is D

To find the incorrect match, let’s compare each respiratory volume with its typical value for a healthy adult.
Tidal volume, the air moved during normal breathing, is about 500 mL—option (1) is correct.
Inspiratory Reserve volume, the extra air inhaled beyond tidal volume, is typically 2,500–3,000 mL, so 2,500 mL in option (2) is correct.
Residual volume, the air remaining in the lungs after maximum exhalation, is around 1,200 mL—option (3) is correct.
Expiratory Reserve volume, the additional air exhaled beyond tidal volume, is usually 1,000–1,200 mL, but option (4) lists it as 3,000 mL, which is too high and incorrect.

Final Answer: The incorrect match is Expiratory Reserve volume – 3,000 mL, so the correct option is (4).
