lung volume and capacities

Which of the following lung volumes cannot be measured directly using a spirometer?

• Tidal Volume (TV)

• Inspiratory Reserve Volume (IRV)

• Residual Volume (RV)

• Expiratory Reserve Volume (ERV)

What is the typical value of tidal volume (TV) in a healthy adult?

• 100 mL

• 500 mL

• 1000 mL

• 1500 mL

If a person's inspiratory reserve volume (IRV) is 3000 mL and their tidal volume (TV) is 500 mL, what is their inspiratory capacity (IC)?

• 2500 mL

• 3000 mL

• 3500 mL

• 4000 mL

A patient has a total lung capacity (TLC) of 6000 mL and a functional residual capacity (FRC) of 2400 mL. What is their inspiratory capacity (IC)?

• 2400 mL

• 3600 mL

• 4800 mL

• 6000 mL

Which lung capacity represents the total volume of air that can be exhaled after a maximal inhalation?

• Vital Capacity (VC)

• Functional Residual Capacity

• Total Lung Capacity

• Inspiratory Capacity

A person has a tidal volume (TV) of 500 mL, an inspiratory reserve volume (IRV) of 3000 mL, and an expiratory reserve volume (ERV) of 1200 mL. What is their vital capacity (VC)?

• 3700 mL

• 4200 mL

• 4700 mL

• 5200 mL

If a patient's residual volume (RV) increases due to a lung disease, which of the following lung capacities will also increase?

• Vital Capacity

• Inspiratory Capacity

• Functional Residual Capacity

• Total Lung Capacity

Which of the following is true about functional residual capacity (FRC)?

• It is the volume of air remaining in the lungs after a normal exhalation.

• It is the sum of tidal volume and inspiratory reserve volume.

• It can be measured directly using a spirometer.

• It decreases in obstructive lung diseases.
