The aim of this study is to examine the effect of warm water foot bath applied before pituitary adenoma surgery on anxiety level and physiological parameters. The main hypotheses are: * H1 = Foot bath group patients have lower state anxiety than control group patients. * H2 = Foot bath group patients have lower anxiety than control group patients. * H3 = Foot bath group patients have lower pain levels than control group patients. * H4 = Foot bath group patients have lower mean arterial blood pressure than control group patients. * H5 = Foot bath group patients have lower heart rates than control group patients. * H6 = Foot bath group patients have lower respiratory rates than control group patients. * H7 = Foot bath group patients have higher body temperatures than * H8 = Foot bath group patients have higher oxygen saturation than control group patients. On the day of surgery, participants will be asked to keep their feet in 40 warm water for 20 minutes, 1 hour before the surgery. If there is a comparison group: Researchers will compare the control group to see if there are any differences in the patients' anxiety level and physiological parameters.
