Older adults are more prone to respiratory problems because aging causes which change?
increased secretion production
thinning of the alveolar membrane
increased efficiency of the immune system
decreased elasticity of the respiratory tissues
The Correct Answer is D
A. Increased secretion production: Older adults often experience decreased secretion clearance rather than increased production.
B. Thinning of the alveolar membrane: Alveolar membranes tend to thicken, reducing efficient gas exchange.
C. Increased efficiency of the immune system: Aging typically causes immune function to decline, increasing susceptibility to infections.
D. Decreased elasticity of the respiratory tissues: Loss of elasticity reduces lung compliance, leading to diminished respiratory efficiency.

Correct Answer is ["A"]
Explanation
A. Incomplete expirations: Age-related decreased lung elasticity impairs full expiration, trapping air in the lungs.
B. Decreased oxygen saturation: Age-related changes in lung tissue reduce gas exchange efficiency.
C. Impaired cilia: Decreased ciliary function reduces the ability to clear mucus and pathogens from the airway.
D. Increased elasticity in thorax and respiratory tissues: Elasticity decreases with aging, reducing lung compliance.
Correct Answer is B
Explanation
A. Removing any adhesive from the patient's skin with acetone: Acetone is highly flammable and should not be used near oxygen equipment.
B. Assessing equipment in room for frayed cords: Frayed cords can cause electrical sparks, which may ignite in an oxygen-rich environment.
C. Reducing humidification on the oxygen delivery device: Humidification is essential to prevent mucosal dryness; reducing it unnecessarily can cause airway irritation.
D. Using clothing of synthetic cloth for the patient: Synthetic materials generate static electricity, which can ignite in the presence of oxygen. Cotton clothing is preferred.
