Which of the following is a common sign of shock?

Anxiety and restlessness are indeed common signs of shock. When a person is experiencing shock, their body may be responding to decreased blood flow and oxygen supply to vital organs. This response can induce feelings of anxiety and restlessness as the body's systems become distressed. As blood circulation diminishes, the brain can react by creating a sense of unease or panic, prompting behaviors associated with restlessness.

Each of the other options listed may pertain to different medical conditions or situations. Yellowing of the skin is more commonly associated with liver issues or jaundice, while severe abdominal pain can indicate a variety of problems such as gastrointestinal issues or trauma rather than shock itself. Excessive sweating may occur in many circumstances, including stress or fever, but it is not as directly indicative of shock as anxiety and restlessness. Recognizing the signs of shock is crucial for timely medical intervention, emphasizing the importance of identifying anxiety and restlessness during the assessment of a patient.
