A nurse is teaching a client how to self-administer daily low-dose heparin injections. Which of the following factors is most likely to increase the client's motivation to learn?

The correct answer is B because when a client believes that their needs will be met through education, they are more likely to be motivated to learn. This belief creates a sense of purpose and relevance, driving the client to engage in the learning process.

Explanation of other options:
A: While it's important for the nurse to explain the need for education, this may not directly increase the client's motivation if they don't see the relevance to their needs.
C: Seeking family approval may provide external motivation but may not necessarily lead to intrinsic motivation for learning.
D: Nurse empathy is important for building rapport but may not be the primary factor in increasing motivation to learn.
