What is a common symptom during deep mouth breathing in geriatric patients?

• A. Shortness of breath at rest
• B. Dizziness
• C. Tire easily
• D. Chest pain

Answer: (C)

Deep mouth breathing in older adults requires more effort from the respiratory muscles and can make ventilation less efficient. Because aging often brings reduced respiratory reserve and lower muscle endurance, this extra work quickly burns energy, so the person tends to tire easily. In other words, the pattern of deep, forceful breathing drains stamina faster than normal, everyday activity.

Other options would suggest symptoms that are less directly tied to the extra effort of deep breathing: shortness of breath at rest implies ongoing or severe breathing trouble rather than a pattern seen with deliberate deep breathing; dizziness and chest pain can occur for different reasons and are not as consistently linked to the act of deep mouth breathing in geriatric patients.
