Which of the following is NOT an indicator for lowered vital signs?

Stress is not typically an indicator for lowered vital signs. In veterinary medicine, stress can cause an increase in heart rate and respiratory rate as the body enters a heightened state of alertness. Animals experience physiological changes due to stress, including the release of adrenaline, which can elevate blood pressure and lead to increased activity of the heart and lungs.

In contrast, fever is characterized by an elevated body temperature, which can indicate an ongoing infection or inflammatory process. Shock is a serious condition that can lead to a decrease in blood pressure and inadequate blood flow to organs, often resulting in lowered heart rate and respiratory rate. Dehydration can also contribute to lower vital signs due to reduced blood volume and overall bodily function.

Thus, stress leads to heightened vital signs rather than lowered ones, making it the correct choice as the option that is not an indicator for this condition.
