Final answer:
The best behavioral objective for improving short-term memory recall in a client with TBI is 'C. The client will correctly restate 75% of the directions given by the CTRS during group,' as it's specific and measurable.
Step-by-step explanation:
A behavioral objective for a client with a traumatic brain injury (TBI) to increase short-term memory recall should include specific, measurable, attainable, relevant, and time-bound (SMART) elements to be effective. Considering the strategies mentioned, the best option among the given choices is: 'C. The client will correctly restate 75% of the directions given by the CTRS during group.' This objective is specific and measurable, and it pertains directly to increasing the client's short-term memory recall, which is a typical challenge faced by individuals with TBI.
Such objectives can be complemented by interventions like expressive writing, cognitive retraining, and memory exercises such as the three-word recall test or reciting items in reverse order. Additionally, innovative approaches like neurofeedback have shown potential in assisting individuals with traumatic brain injury by improving cognitive functions, including memory.
