Which of the following is NOT a common central nervous system manifestation of anaphylactic shock?

In the context of anaphylactic shock, the central nervous system manifestations typically include symptoms such as anxiety, headache, and confusion. These are often attributed to the body’s response to severe allergic reactions, which can lead to hypoxia, changes in blood pressure, or a lack of oxygen to the brain, all contributing factors that can affect cognitive function and mental state.

Combativeness, on the other hand, is not a commonly recognized symptom related to the central nervous system during anaphylaxis. While agitation or a heightened state of distress can occur during an acute allergic reaction, it is not specifically labeled as combativeness in medical literature. Instead, individuals may display anxiety or confusion due to the body's overwhelming physiological response. Therefore, recognizing combativeness as a non-typical manifestation underlines the importance of understanding the nuanced responses the body exhibits in life-threatening situations such as anaphylaxis.
