Final answer:
The nurse should assess the client's learning style first before planning the teaching session.
Step-by-step explanation:
The nurse should take the action of assessing the client's learning style first.
Before planning the teaching session, it is important to understand how the patient learns best so that the teaching can be tailored to their individual needs. By assessing the client's learning style, the nurse can determine if the patient is a visual learner, auditory learner, or kinesthetic learner, and use appropriate teaching methods accordingly.
Once the learning style is assessed, the nurse can then plan the teaching session, treat the client's pain, and ask about pain management strategies as necessary.
