Abstract
Aim. The aim of this study was to examine the effect of teach back learning strategy on illness perception, nutritional knowledge and dietary adherence in people with hypertension.
Background. Because of the chronicity of hypertension and the importance of nutrition in hypertension control, illness perception and nutritional knowledge play an important role in adherence to nutritional regimen and disease control.
Method. The present study is a quasi-experimental study control group and pretest-posttest design. Based on random sampling, two health care centers in Ferdows were selected as the place for experimental and control group. Using a simple randomized method, of patients with hypertension, 35 individuals were recruited for each group. These people entered the study based on inclusion criteria and after that they signed the consent form. Before and after the intervention, illness perception, nutritional knowledge and dietary adherence were measured by self-report questionnaire and compared between the groups.
Findings. After intervention, the mean score of nutritional knowledge in experimental and control group was 48.17±5.21 and 41.16±0.51, respectively, and a statically significant difference was found between groups in terms of nutritional knowledge (P≤0.0001; t=9.56). After intervention, the mean score of illness perception in experimental and control group was 9.75±1.81 and 7.72±1.60, respectively, and there was a statically significant difference between groups in terms of illness perception (P≤0.0001; t=4.15). But no statically significant difference was found between experimental and control group in terms of dietary adherence (17.55±4.17 against 16.88±3.62).
Conclusion. Given the positive effects of teach back method and the special role of nurses in patient education, attention to this teaching method seems necessary. The use of this method of training is suggested as part of care process to reduce patients' clinical problems.

Abstract
Aim. The aim of this literature review was to investigate the importance of adherence to diet in and nutritional recommendations for patient after coronary artery bypass graft surgery.
Background. Nutritional patterns after heart surgery are among the most important aspects of care that is provided by the nurse. Due to the importance of this issue, various studies have been conducted to focus on principles of proper nutrition after coronary artery bypass graft surgery and the necessary recommendations.
Method. The present review study was conducted through searching out databases and search engines Pub Med, SID, MagIran, Web of Sciences, Cochrane Library, CINHAL, OVID, Up-to-date, and Scopus without time limit using the keywords Coronary artery bypass graft surgery, Adherence to nutrition therapy, Cardiovascular disease, Survival rate, Complications of heart disease and nursing care, Diet, and Nutritional support. Out of a total of 103 articles, 65 articles with accessible full text entered the qualitative review stage, of which 51 articles entered the literature review.
Findings. The use of appropriate dietary approach such as consumption of fruits and vegetables, nuts and nuts, consumption of dairy products, fish and cooked and steamed foods should be the first priority of patients after coronary artery bypass graft surgery. They should avoid of fried and processed materials as much as possible.

Abstract
Aim. The purpose of this study is to review studies that have investigated the effect of family-centered self-care program on the activity of people with cardiovascular disease after hospital discharge.
Background. Adherence to medication, diet and physical activity in people with cardiovascular disease is very crucial to prevent readmission, independence in daily activities, and complications.
Method. In this review study, a comprehensive search of scientific databases and search engines such as Science Direct, Scopus, PubMed, Google Scholar, and Medline using the keywords cardiovascular disease, adherence to treatment regimen, and family-centered self-care program in both Persian and English languages was done to find articles published between 2000 and 2020.
Findings. Family-centered post-discharge self-care program can be a principled and effective method to increase adherence to medication, diet and physical activity in heart people with cardiovascular disease.
Conclusion. One of the most important factors in effectiveness of self-care is active family participation and family-centered self-care, which can be effective in three areas after the discharge of people with cardiovascular disease.

Abstract
Aim. The present review study was conducted with the aim of exploring what nurses should know about interactions of diet containing vitamin K with warfarin.
Background. Warfarin is one of the most widely used oral anticoagulants. Dietary interactions, mainly due to vitamin K, are a common concern when consuming warfarin. In the meantime, the nurse, as the first person in the care chain and the main person in charge of patient education, can play an important role in reducing these interactions, which is a challenge for patients.
Method. The present review study was conducted through searching out library as well as databases such as PubMed, Cochrane Library, Web of Science, Scopus, Up-to-date, OVID, CINAHL, Magiran and SID using Persian keywords of warfarin, dietary interactions, vitamin k diet, patient and nurse education and their English equivalents in the period 1999 to 2021. Out of a total of 30 articles found, 8 articles were reviewed after screening the articles.
Finding. The findings of this study showed that the amount of vitamin K intake in the diet should be kept constant. This is 90 to 120 micrograms per day. Patients should be properly and continuously educated about vitamin K in various foods and supplements. In the meantime, the role of the nurse as one of the pillars of patient education is very important and fundamental.
Conclusion. Due to the role of the nurse in educating these patients, it is recommended that education about dietary interactions be used using authoritative sources. It is possible with methods such as preparing a clinical guide, making a video and designing an application, and including tables of vitamin K levels in foods.
