Cultural sensitivity is very important for improving the competency of nursing students because patients have a variety of beliefs and self-identities. When nursing students understand the belief, especially the health belief, they can plan the activity and solve the problems or potential problems in the family. This study’s aim was to understand how their cultural background influences their health care behaviors. The practicum of community health nursing subjects is a very important subject for nursing students to confront the real situation, so they have experienced the health determinants that can affect the health of each person. For example, in the hospital setting, nursing students cannot see the reason that the patients cannot control their blood pressure because they know about the medicine they have after breakfast, but they have breakfast at ten or eleven o’clock, so the medicine can be late. The whole family has chronic disease, hypertension, diabetes mellitus, dyslipidemia, and psychiatric problems. The holistic care concept, which launched in taking care of the entire family, especially spiritual care, is very important, so this is the best way to integrate cultural sensitivity competency together. The results found that families have the holy things for healing when they are confronted with a health problem that cannot find out the cause, their belief about take medicine after a meal, but the time will be late, but they have the diet behaviors were good they have a lot of vegetables and all of them is from the plant by themselves, and they have the cultural that they call Rum-Thai- Paun is very surprisingly they can sing and play together even though are not all of them. The researchers expect that in the future, we can present more details for better health.
