Final answer:
The statement indicating the client is not ready to learn at the moment is "There's no sense in showing me that now. I'm too sick right now.", as it shows a lack of willingness or ability to engage in the learning process.
Step-by-step explanation:
The nurse would evaluate the statement "There's no sense in showing me that now. I'm too sick right now." as an indication that the client is not ready to learn at this time. This statement reflects a lack of immediate willingness or capacity to engage in the learning process, possibly due to the client's current state of health. In contrast, the other statements suggest a degree of readiness and openness to learn in the near future or a request for validation of learning.
