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 D
Explanation
A) Took five quick "huffs" and then coughed vigorously. Huff coughing is a technique used to clear secretions, but it is not the correct method for using an incentive spirometer.
B) Exhaled deeply and then inhaled quickly and forcefully three times. Rapid inhalation and exhalation do not promote effective lung expansion or alveolar recruitment.
C) Took five deep breaths slowly every 4 hours. This frequency is insufficient to prevent atelectasis and postoperative lung complications.
D) Took 10 slow, deep breaths every hour. Taking 10 slow, deep breaths every hour encourages full lung expansion and prevents complications such as atelectasis.
Correct Answer is B
Explanation
A) Sternum. Percussion over the sternum is ineffective and may cause discomfort.
B) Thorax. Percussion on the thorax helps loosen mucus in the underlying lung fields.
C) Midaxillary line on the rib cage. This area is not typically targeted for percussion.
D) Spine between the scapulae. Percussion on the spine is not advisable due to the potential for discomfort and ineffectiveness. The area between the scapulae is also less effective for loosening mucus compared to the thorax.
