What is a potential complication of general anesthesia?

Respiratory depression leading to inadequate ventilation is a known potential complication associated with general anesthesia. During the administration of general anesthesia, various anesthetic agents can depress the central nervous system, particularly the brainstem areas responsible for autonomic control of breathing. This suppression can result in a decreased respiratory rate and depth, leading to inadequate ventilation. In such cases, healthcare providers must be vigilant and prepared to assist or provide ventilation to the patient, typically through bag-mask ventilation or mechanical ventilation, until the effects of the anesthetics wear off.

Inadequate patient awareness during surgery, while a concern, is less of a complication in modern general anesthesia due to monitoring and advances in anesthetic techniques. Excessive mobility during the procedure is not typically associated with general anesthesia, as the aim is to provide immobility and lack of awareness during surgery. Lastly, nausea avoidance post-operation pertains to post-operative care and management focused on preventing nausea rather than a direct complication of the anesthesia itself. Thus, B is the most relevant and identified risk associated with the effects of general anesthesia.
