Question

Match the items given in Column I with those in Column II and select the correct option given below :

Column I		Column II
a.	Tidal volume	i.	2500 – 3000 mL
b.	Inspiratory Reserve volume	ii	1100 – 1200 mL
c.	Expiratory Reserve volume	iii.	500 – 550 mL
d.	Residual volume	iv.	1000 – 1100 mL

• A. a-iii, b-ii, c-i, d-iv
• B. a-i, b-iv, c-ii, d-iii
• C. a-iii, b-i, c-iv, d-ii
• D. a-iv, b-iii, c-ii, d-i

Answer 1

The Correct Option is C

To solve this matching question, we need to associate each item from Column I with the correct description or value from Column II based on our knowledge of respiratory volumes.

Column I Descriptions:

1. Tidal Volume (TV): This is the volume of air inhaled or exhaled during normal breathing. In adults, this value is typically around 500 mL, falling within the range of 500 – 550 mL.
2. Inspiratory Reserve Volume (IRV): The additional air that can be forcibly inhaled after the inspiration of a normal tidal volume. This is typically about 2500 – 3000 mL.
3. Expiratory Reserve Volume (ERV): The additional amount of air that can be expired from the lungs by determined effort after normal expiration; this is about 1000 – 1100 mL.
4. Residual Volume (RV): The volume of air remaining in the lungs after a maximum exhalation, generally around 1100 – 1200 mL.

Using this information, we can match each item in Column I with the correct item in Column II:

• Tidal Volume (TV) matches with iii. 500 – 550 mL.
• Inspiratory Reserve Volume (IRV) matches with i. 2500 – 3000 mL.
• Expiratory Reserve Volume (ERV) matches with iv. 1000 – 1100 mL.
• Residual Volume (RV) matches with ii. 1100 – 1200 mL.

Conclusion: The correct option is:

a-iii, b-i, c-iv, d-ii
