Final answer:
To check if a 70-year-old client with a fractured wrist has retained the taught information, use recall tests like the three-word recall test and observe the client's explanation and demonstration of care techniques.
Step-by-step explanation:
The best method to determine whether a client has retained the information taught about caring for a fractured wrist is to use interactive and recall-based assessment techniques. For a 70-year-old patient, one effective approach is the three-word recall test, where the patient is given three words to remember and is asked to recall them after a short interval. This method evaluates the patient's short-term memory and retention.
Another method is to have the client explain back to the nurse the steps they would take in caring for their wrist. It is also helpful to observe the patient demonstrating the care techniques that were taught. This not only assesses their recollection but also their ability to physically carry out the necessary tasks, which is particularly important in elderly patients who may have age-related physical limitations.
