Final answer:
The laboring patient using a cool, dark compress on her forehead is employing thermal stimulation, a stress and pain management technique during labor.
Step-by-step explanation:
Applying a cool, dark compress over the forehead during labor is an example of thermal stimulation. This relaxation technique is used to help with pain relief and stress reduction during labor by providing a change in temperature, which can be soothing and help redirect the patient's focus away from contractions. Thermal stimulation, as a type of non-pharmacologic pain management, can be used alongside other techniques like meditation and biofeedback, which are known to help with stress management, blood pressure regulation, and pain management.
