Which of the following is a potential side effect of general anesthesia used in dentistry?

Nausea and vomiting are indeed recognized as potential side effects of general anesthesia, commonly experienced after surgical procedures. When patients undergo anesthesia, the body can react in various ways as it processes the drugs used to induce unconsciousness. The gastrointestinal system is sensitive to these changes, and for some individuals, this can result in feelings of nausea or subsequent vomiting.

General anesthesia affects the central nervous system and temporarily alters the normal functioning of the body, which can lead to discomfort after the procedure. It's important for dental practitioners to monitor their patients post-op for these side effects and provide support as needed.

In contrast, the other options—improved dental health, increased energy levels, and enhanced taste sensitivity—do not correlate with the effects of general anesthesia. Improved dental health is the desired outcome of dental treatments rather than a side effect of anesthesia. Increased energy levels and enhanced taste sensitivity are not typical effects associated with the depressant nature of general anesthetics, which can induce drowsiness rather than alertness. Therefore, nausea and vomiting stand out correctly as a notable and possible side effect of general anesthesia used in dentistry.
