Patients will not be taught breathing exercises. Pain will be assessed with the VAS at the 6th, 12th, and 24th postoperative hours, and anxiety will be assessed with the STAI-II on the preoperative morning and before discharge.

Pranayama breathing techniques will be taught before surgery. Starting 4 hours after surgery, 8-10 minutes of breathing exercises will be repeated every 2 hours. Pain will be measured before and after the exercises and at 6, 12, and 24 hours postoperatively. Anxiety will be measured with the STAI-II on the morning of the preoperative period and before discharge.

Deep breathing exercises will be taught before surgery. Six repetitions will be performed every two hours, starting four hours after surgery. Pain will be assessed with a VAS before and after the exercise and at 6, 12, and 24 hours. Anxiety will be measured with the STAI-II on the morning of the preoperative period and before discharge.

Pranayama breathing technique consisting of 6 cycles, demonstrated by the researcher before the operation, supported by the brochure, and lasting 8-10 minutes every 2 hours from the 4th post-operative hour.

Spielberger State-Trait Anxiety Inventory: First developed by Spielberger and his colleagues in 1970, it was adapted into Turkish by Öner and Le Compte (1982), and its validity and reliability studies were conducted. This inventory consists of two subsections, each containing 20 items: State Anxiety (STAI-I) and Trait Anxiety (STAI-II). In the state anxiety section, participants select one of the following options: "not at all," "a little," "a lot," or "completely." In the trait anxiety section, participants respond with the following options: "almost never," "sometimes," "most of the time." The total score on the scale ranges from 20 to 80; higher scores indicate higher anxiety levels. In the study conducted by Günaydın and Oflaz (1998), anxiety scores were classified according to their levels and defined as 20-39 as "mild", 40-59 as "moderate", 60-79 as "high" and over 80 points as "panic level anxiety".

Visual Analog Scale (VAS) The Visual Analog Scale (VAS) was designed in 1983 by Price and colleagues to assess pain intensity. This measurement tool consists of a 10-cm-long straight line with the words "no pain" at one end and "unbearable pain" at the other. The patient is asked to mark a point on the line corresponding to the intensity of the pain they are experiencing; this point is scored in centimeters from the beginning. The score is categorized as no pain for 0, mild for 1-4, moderate for 5-6, severe for 7-8, and extreme pain for 10.
