20 ANSWER 

B) How the pain affects the client's daily life.

Explanation

Chronic pain is multidimensional, often without an identifiable cause and not responsive to conventional treatment. By asking how/if the pain interferes with the client's daily activities, the nurse will obtain information about the impact the pain has on the person's quality of life. Recognize that the question is asking about planning care. Reference to interruption of daily life and activities is a hint to the correct response.
