Final answer:
A nurse should consider the cultural practice of coining when assessing welts on the body of a 2-year-old Vietnamese child.
Step-by-step explanation:
When assessing welts on the body of a 2-year-old Vietnamese child, a nurse should consider the skin lesions might be the result of the cultural practice of coining. Coining is a traditional therapy commonly practiced in Vietnamese culture where a heated coin is rubbed on the skin to alleviate symptoms of various illnesses. The rubbing action leaves welts or red marks on the skin. Although this practice may raise concerns about child abuse, it is important for healthcare professionals to understand the cultural context before making any judgments.
