After obtaining permission from the experimental group with the "Informed Consent Form" the day before the surgery, the patients who agree to participate in the study will fill out the "Patient Introduction Form" by the researchers. The respiratory exercises will be taught and monitored by the researchers, and the researcher who will perform them works as a nurse in the general surgery department. The experimental group will be trained on respiratory exercises by the researcher the day before the surgery. The patients will be asked to perform the post-operative respiratory exercises as 1 set (4 breaths) per hour. The patient's vital signs will be monitored before and after the respiratory exercise. Patients will not have difficulty during the respiratory exercise, they will be asked to do it gradually. Pain conditions will be monitored at 0, 2, 6, 12 and 24 hours during the 24-hour hospital stay. The recovery quality scale will be applied on the 1st and 3rd days after the surgery.

In the control group, after obtaining permission with the "Informed Consent Form" the day before the surgery, the patients who agreed to participate in the study will fill out the "Patient Introduction Form" by the researchers, and their pain status will be monitored at 0, 2, 6, 12 and 24 hours during the 24-hour hospital stay after the surgery. The quality of recovery scale will be applied on the 1st and 3rd days after the surgery. No intervention will be made to the patients in the control group, and they will receive routine nursing care provided in the hospital.

The scale consists of a 10 cm long horizontal line and the score is determined by measuring the distance between the leftmost end of the scale and the point marked by the patient. The score range from 0 to 10 on this scale and higher scores indicate increased pain severity.

It was developed by Myles et al. (2000) and its Turkish validity and reliability were conducted by Karaman et al. (2014). The questionnaire consists of 40 items and five sub-dimensions as 'Emotional State, Physical Comfort, Patient Support, Physical Independence, and Pain'. Each item in the questionnaire is scored on a Likert-type scale ranging from 1 to 5. This classification is as follows: 1= Never, 2= Sometimes, 3= Usually, 4= Most of the time, 5= Always. The total score obtained from the scale varies between 40 and 200. An increase in the score obtained from the questionnaire indicates that the physical and emotional well-being of the patients increases in the postoperative period; a decrease indicates that the physical and emotional well-being of the patients is negatively affected (Myles et al. 2000; Karaman et al. 2014). The Cronbach's alpha coefficient of the questionnaire was determined as 0.936 (Karaman et al. 2014).
