Even if a health care professional is employed by an agency that delivers orthodox health care, what general holistic concepts can be applied to improve patient care?                              

The holistic concept that can be applied to improve patient care is to ask how the patient feels about their treatment.

Explanation:

Orthodox medicine is one that uses conservative medical concepts and believes that only physical and biological factors influence the onset and effective treatment of a disease, so they make constant use of traditional medicines and techniques to diagnose and treat disease.

On the other hand, practitioners of orthodox medicine often use some holistic concepts, which is an approach that states that various aspects of human life such as the physical, psychological, spiritual and sociological factors are influential at the time when it is necessary to dignify, control and prevent the development of disease.

One way for a member of orthodox medicine to use holistic concepts in general is by asking how the patient feels about treating the disease. By asking this question, the professional shows that he is assessing whether the patient's emotional state will influence the success of the treatment.
