A client who had emergency gallbladder surgery yesterday is getting ready for discharge. The client speaks very little English. When teaching wound care, which method should the nurse use to evaluate the client's understanding of self-care at home?

A. After each instruction, ask if the client understands is not the most reliable method because the client may answer affirmatively out of politeness or lack of comprehension. B. Provide written instructions in the client's native language is helpful as a supplementary teaching tool but does not evaluate the client's understanding or ability to perform wound care. C. Have the client demonstrate prescribed wound care is the most effective method because it allows the nurse to directly observe the client’s technique and understanding, ensuring they can perform the task correctly at home. D. Have an interpreter repeat the wound care instructions ensures accurate communication but does not assess whether the client can perform the care independently.
