Verified
The patient is breathing normally. Which process does the nurse consider is working properly when the patient inspires?
A) Stimulation of chemical receptors in the aorta
B) Reduction of arterial oxygen saturation levels
C) Requirement of elastic recoil lung properties
D) Enhancement of accessory muscle usage
Elastic Recoil
The ability of an organ or tissue to return to its original shape after being stretched or compressed.
Chemical Receptors
Proteins in cells that bind to specific chemicals, allowing the cell to respond to various signals and changes in its environment.
Arterial Oxygen Saturation
A measure of the amount of oxygen bound to hemoglobin in the blood, indicating how well oxygen is being transported to body tissues.

Final Answer :
A
Explanation :
Inspiration is an active process, stimulated by chemical receptors in the aorta. Reduced arterial oxygen saturation levels indicate hypoxemia, an abnormal finding. Expiration is a passive process that depends on the elastic recoil properties of the lungs, requiring little or no muscle work. Prolonged use of the accessory muscles does not promote effective ventilation and causes fatigue.
