A. Perception occurs when the brain interprets pain signals and recognizes them as pain. This step happens after the nerve impulses have been transmitted to the brain.
B. Transduction is the first step in the pain process, where painful stimuli (such as cutting a finger) activate nociceptors, converting the stimulus into an electrical signal.
C. Modulation involves the body’s response to pain signals, where descending nerve pathways release substances like endorphins to inhibit pain transmission. This occurs later in the pain process.
D. Transmission is the process of pain signals traveling from the site of injury to the spinal cord and brain via afferent nerve fibers. This step occurs after transduction and allows pain signals to reach the central nervous system.

A. Posterior-to-anterior comparison. While both the anterior and posterior lung fields should be assessed, auscultation should be performed in a systematic side-to-side manner rather than switching between front and back.
B. Side-to-side comparison. The correct method for auscultating breath sounds is to compare sounds bilaterally (right lung to left lung) at each level. This helps identify asymmetrical lung sounds, which could indicate conditions like pneumonia, pleural effusion, or atelectasis.
C. Top-to-bottom comparison. While lung auscultation progresses from the apices to the bases, it should always be done in a side-to-side manner to detect differences between the lungs.
D. Interspace-by-interspace comparison. Although breath sounds are assessed at different intercostal spaces, the key principle is to compare sounds bilaterally at each level, rather than focusing solely on individual interspaces.
