Final answer:
Phenergan and Vistaril tranquilizers are used during labor for anxiety reduction due to their calming effects.
Step-by-step explanation:
Tranquilizers such as Phenergan and Vistaril are used in labor primarily for anxiety reduction. These medications are part of a group known for their sedative and hypnotic properties, which contribute to their calming effects and ability to reduce anxiety and tension. Although they may indirectly aid in pain relief due to their overall sedative effects, tranquilizers are not directly employed for uterine stimulation, blood pressure control, or pain relief in the context of labor.
Tranquilizers such as Phenergan and Vistaril are used in labor to reduce anxiety. They are drugs that relieve the symptoms of anxiety and tension, causing calming effects and drowsiness. They do not have a direct effect on pain relief, uterine stimulation, or blood pressure control.
