The nurse is caring for an elderly patient who has been admitted with pneumonia.
The nurse knows that elderly patients are at increased risk for respiratory infections because of which of the following factors?
(Select all that apply.).
These are the factors that increase the risk of respiratory infections in elderly patients:.
• Decreased immune response: Elderly patients have a weaker immune system that makes them more susceptible to viral and bacterial infections. They also have a poor response to respiratory vaccines.
• Decreased chest wall compliance: Elderly patients have reduced elasticity of the lungs and chest wall, which makes it harder for them to breathe and expel mucus.
• Decreased alveolar surface area: Elderly patients have fewer and larger alveoli, which reduces the gas exchange area and oxygen diffusion capacity.

• Decreased chest wall compliance: Elderly patients have reduced elasticity of the lungs and chest wall, which makes it harder for them to breathe and expel mucus.
• Decreased alveolar surface area: Elderly patients have fewer and larger alveoli, which reduces the gas exchange area and oxygen diffusion capacity.
This is wrong because decreased oxygen saturation is not a risk factor, but a consequence of respiratory infections.
This is wrong because decreased bronchial dilation is not a specific factor for elderly patients, but a common feature of obstructive lung diseases.
The correct answer is A, B and C.

Choice D is wrong because decreased oxygen saturation is not a risk factor, but a consequence of respiratory infections.
Choice E is wrong because decreased bronchial dilation is not a specific factor for elderly patients, but a common feature of obstructive lung diseases.
Normal ranges for oxygen saturation are 95-100% and for bronchial dilation are variable depending on the type and severity of the disease.
