Which of the following is a mild symptom of hypovolemic shock?

Headache and dizziness are indeed mild symptoms of hypovolemic shock. In the early stages of this condition, a person may experience a drop in blood volume, leading to reduced oxygen delivery to the brain and other vital organs. This decreased perfusion can result in mild neurological symptoms such as headache and dizziness, which can be a warning sign that the body's compensatory mechanisms are beginning to struggle.

Other options like cold or clammy skin, rapid shallow breathing, and confusion or weakness tend to indicate more advanced or severe stages of hypovolemic shock. Cold and clammy skin suggests vasoconstriction and decreased perfusion, rapid shallow breathing can reflect the body's attempts to compensate for low blood volume, and confusion or weakness indicates significant cerebral hypoperfusion and should not be viewed as mild symptoms. Therefore, experiencing headache and dizziness can serve as an early indicator of the body's initial response to hypovolemic shock.
