Why is respiratory care of increased importance to older adults?
They are reluctant to get flu and pneumonia vaccinations
Decreased activity due to aging lowers oxygenation.
Increased demands on the aging body increase risks of infection
Chronic pulmonary disease is the third leading cause of death in older adults
The Correct Answer is D
A. They are reluctant to get flu and pneumonia vaccinations: While some older adults may be hesitant, this is not the primary reason respiratory care is emphasized.
B. Decreased activity due to aging lowers oxygenation: Decreased activity can affect oxygenation, but it's not the most direct or major reason respiratory care is crucial.
C. Increased demands on the aging body increase risks of infection: Although aging increases susceptibility to infections, this is too broad and not specific to respiratory care.
D. Chronic pulmonary disease is the third leading cause of death in older adults: This is the most compelling and specific reason; chronic respiratory diseases significantly impact morbidity and mortality in the elderly, making respiratory care a priority.

Correct Answer is A
Explanation
A. Degree of motion of all joints
Range of motion (ROM) reflects joint function, mobility, and physical independence, making it the most comprehensive and important musculoskeletal assessment.
B. Enlarged joints
This could indicate arthritis, but it does not quantify functional ability like ROM does.
C. Crepitus in joints
Common in older adults due to cartilage breakdown, but it is not as clinically significant as functional assessment.
D. Slow gait
Important but less specific than assessing actual joint mobility across the body.
Correct Answer is A
Explanation
A. Decreased impulse conduction speed
Aging causes slower nerve conduction due to loss of myelin and reduced neurotransmitter activity, leading to slower reflexes and response times.
B. Atherosclerosis and decreased cellular respiration
These factors affect circulation and energy production but are not primary causes of slowed neurologic responses.
C. Inadequate tissue oxygenation
Can affect brain function acutely, but it's not the main cause of chronic, gradual slowing in the elderly.
D. Loss of neurons in the brain
While this occurs with aging, slowed reflexes are more specifically linked to nerve impulse transmission rather than neuron quantity alone.
