What is a consequence of entering the resistance stage?

Entering the resistance stage of the general adaptation syndrome, which occurs after the initial alarm reaction to stress, is characterized by the body attempting to adapt to prolonged stressors. During this phase, the body's ability to manage stress improves, leading to a restoration of physiological functions such as pulse and blood pressure back towards normal levels.

In this stage, while the individual is still under stress, the body's systems are engaged in coping mechanisms to maintain homeostasis. It doesn't eliminate the stressor but enables better management of its effects. This is why the restoration of pulse and blood pressure to normal is a key feature in the resistance stage; it indicates that the body is adapting and functioning more effectively despite the ongoing stress.

The other options do not accurately depict the effects of entering this stage. Complete unawareness of stressors, an immediate return to good health, or persistent deterioration of mental focus would not typically characterize the resistance stage, as it is about adaptation rather than being oblivious to stress, a quick recovery to health, or worsening mental faculties.
