Which of the following can be symptoms of shock?

Symptoms of shock often manifest as changes in mental status and overall body function due to inadequate blood flow to the tissues. Confusion, combativeness, and anxiety are indicative of altered mental status, which occurs when the brain does not receive enough oxygenated blood. This can lead to agitation or a decreased level of consciousness as the body responds to the stress of shock.

Other options present characteristics that are not associated with shock. For instance, clear communication suggests cognitive functioning is intact, while healthy skin color indicates proper circulation, both of which are typically absent in a person experiencing shock. Similarly, stable vital signs would indicate that the body is maintaining normal function, which contradicts the situation of an individual in shock where vital signs are often unstable.
