Which condition would most warrant diaphragmatic breathing as part of therapy?

• A. Atelectasis
• B. Hyperoxemia
• C. Bradypnea
• D. Consolidation

Answer: (A)

Promoting deeper diaphragmatic breaths to recruit and re-expand collapsed alveoli is a primary goal of this technique. Atelectasis often results from shallow breathing that lets small airways collapse; by increasing tidal volume through diaphragmatic movement, you improve ventilation of poorly inflated areas and help reopen collapsed units, which aids oxygenation and reduces work of breathing. This makes diaphragmatic breathing especially beneficial in atelectasis. The other options don’t fit as directly: high oxygen levels aren’t treated with this breathing pattern, and while slowing the breathing rate or addressing consolidation can be part of therapy, they’re not the scenario where diaphragmatic breathing has its strongest, most direct impact.
