Which of the following is a common side effect of pediatric anesthesia?

Nausea is a common side effect associated with pediatric anesthesia due to several factors, including the type of anesthesia used, the duration of the surgical procedure, and the individual child's response to the anesthetic agents. After undergoing anesthesia, children may experience postoperative nausea and vomiting (PONV), which can occur as the body clears the anesthetic from its system. This reaction is not only prevalent among children; it is also seen in adults, but children may be more susceptible due to physiological variations and developmental factors.

The other options are less relevant in the context of typical reactions to anesthesia. Hair loss is not a documented side effect associated with anesthesia; it may occur due to stress or other factors, but it is not directly linked to the anesthetic itself. Increased appetite post-anesthesia is not a common occurrence and can vary significantly depending on individual circumstances and the specific procedure performed. Joint pain is also not a typical side effect of anesthesia; while pain following surgery is possible, it is usually related to the surgical site rather than anesthesia itself.
