The client inquires about the purpose of having pneumatic compression devices applied. The nurse understands that the purpose of these devices is to do which of the following:
Prevention of wound infection
Promote circulation of venous blood
Improve mobility
Encourage lung expansion
The Correct Answer is B
A. Prevention of wound infection: Pneumatic compression devices do not actively prevent surgical wound infection; infection prevention relies on aseptic technique, antibiotics as indicated, and wound care.
B. Promote circulation of venous blood: These devices intermittently compress the limbs to enhance venous return, reduce venous stasis, and lower the risk of deep vein thrombosis (DVT).
C. Improve mobility: While used when mobility is limited, the devices themselves do not restore or improve the patient’s ability to ambulate.
D. Encourage lung expansion: Lung expansion is promoted by deep-breathing exercises, incentive spirometry, and positioning; pneumatic compression devices target limb circulation rather than pulmonary mechanics.

Correct Answer is D
Explanation
A. Due to increase in physical activity: Increased activity tends to raise body temperature; older adults typically have lower activity levels, so this does not explain a lower baseline temperature.
B. Increase in subcutaneous body fat and metabolic rate: Increased subcutaneous fat and metabolic rate would tend to conserve heat and raise temperature; aging is associated with the opposite change.
C. Due to an increase in protein intake in their diet: Dietary protein does not directly cause a lower core body temperature in older adults.
D. Decrease in subcutaneous body fat and metabolic rate: Age-related loss of subcutaneous fat and a lower metabolic rate reduce heat production and insulation, contributing to a tendency toward lower body temperature.
Correct Answer is B
Explanation
A. Bronchovesicular: Bronchovesicular sounds are normal breath sounds heard over central airways and are not adventitious findings of bronchoconstriction.
B. Wheezing: Wheezes are high-pitched, musical sounds produced by airflow through narrowed airways and are commonly heard with bronchoconstriction (e.g., asthma).
C. Rales: Rales (crackles) are discontinuous sounds often associated with fluid in the alveoli (e.g., pulmonary edema, pneumonia), not bronchoconstriction.
D. Bruit: A bruit is an abnormal vascular sound heard over arteries and is unrelated to lung auscultation.
