During an assessment of an adult, the nurse has noted unequal chest expansion and recognizes that this occurs in which situation?

A) In an obese patient
B) When part of the lung is obstructed or collapsed
C) When bulging of the intercostal spaces is present

Unequal Chest Expansion

A condition where one side of the chest expands less than the other during breathing, often indicating underlying respiratory or musculoskeletal disorders.

Intercostal Spaces

The anatomical spaces between the ribs that contain muscles, nerves, and blood vessels, important in respiration.

Accessory Muscles

Additional muscles used for increased effort in breathing, particularly when the primary muscles are not sufficient.

Final Answer :
B
Explanation :
Unequal chest expansion occurs when part of the lung is obstructed or collapsed, as with pneumonia, or when guarding to avoid postoperative incisional pain. Chest expansion is still expected to be equal in obese patients, when there is bulging of intercostal spaces, and when accessory muscles are used in breathing.
