The key concepts of the model are culture, culture care, culture care diversities, and similarities relevant to transcultural human care (McEwen & Wills, 2014, p. 233). Other notions are health and illness are perceived differently by all based on individual viewpoints, social class, and ways of handling situations; different approaches to identifying the problem, curing, and care, including folk, and western medical interventions may be required for treatment of illness; and for a nurse to effectively deliver care for a patient of a different background other than their own, effective intercultural connection must take place (Transcultural Nursing, n.d.). For a nurse to provide sensitive culture care, he/she must process and use these concepts. “Cultural competence is defined as a combination of practice viewpoints, congruent behaviors, and guidelines that allows nurses to provide great care in cross-cultural situations” (Leininger & McFarland, 2002, p. 78). Nurses must evaluate his/her own beliefs and be willing to learn and respect another individual’s moral. These concepts are strengths of this theory because not being aware of cultural health differences can be a major block to helping a patient. Cultural knowledge and experience can assist the nurse to finding the right medium may be the perfect fit for delivering the best treatment.
