A nurse is assessing a patient's bilateral pulses for symmetry. Which pulse site should not be assessed on both sides of the body at the same time?

A. Hyperventilation. Opioid overdose depresses the central nervous system, leading to slow and shallow breathing, not increased respiratory rate (hyperventilation).
B. Eupnea. Eupnea refers to normal breathing, which is unlikely in opioid overdose because opioids suppress respiratory drive.
C. Bradypnea. Opioids act on the brainstem's respiratory centers, leading to respiratory depression, characterized by slow breathing (bradypnea) and, in severe cases, respiratory arrest. This is the most life-threatening effect requiring immediate intervention.
D. Hyperpnea. Hyperpnea refers to deep breathing, which is not a typical response to opioid overdose. Instead, breathing becomes slow and shallow, increasing the risk of hypoxia.

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.
