Final answer:
The nurse uses closed-ended questioning and problem-oriented listening techniques in asking about the patient's pain and its relation to walking.
Step-by-step explanation:
In the context of the nurse's questions, "Do you have pain or cramping?" and "Does the pain get worse when you walk?" the interview techniques being used are closed-ended questioning and problem-oriented listening. Closed-ended questions are those that can be answered with a 'yes' or 'no,' or with a very short response. These types of questions aim to gather specific information efficiently. Problem-oriented listening refers to focusing on the issue at hand and seeking information that will clarify the extent and nature of a problem. In this case, the problem is the patient's pain and how it might be affected by activity. The nurse is not making use of active listening which involves paraphrasing and summarizing what the patient says to ensure understanding. Also, these particular questions are not open-ended, which would be designed to elicit a more extensive and detailed response.
