Which of the following includes symptoms such as nausea, dizziness, and excessive sweating after a critical incident?

The correct answer is based on the physiological responses following a critical incident, where symptoms such as nausea, dizziness, and excessive sweating can manifest. This aligns closely with the concept of Sympathetic Nervous System Activation, which describes the body's reaction to stress or perceived threats, commonly known as the "fight or flight" response.

When an individual experiences a critical incident, the sympathetic nervous system becomes activated, leading to the release of stress hormones like adrenaline. This activation prepares the body for rapid response and can cause various physiological symptoms including increased heart rate, nausea, dizziness, and excessive sweating. Understanding this response is crucial for responding appropriately in high-pressure situations and for recognizing the signs of stress on oneself or others following trauma.

While the other options like Critical Incident Amnesia and Psychological Trauma might be associated with psychological states that follow such incidents, they do not primarily encompass the physical symptoms listed. Backlash Triggers relate more to the responses and behaviors that may occur after the initial incident, rather than the acute physical reactions like those described in the question. Thus, recognizing the connection between sympathetic nervous system activation and the physiological symptoms is essential for comprehending responses to critical incidents.
