Following a motorcycle collision, a young adult client's fractured left tibia was surgically repaired and a long leg cast was applied. For the past two days, the client has been ambulating with the use of crutches. The client reports increased weakness in both forearms. Which action should the nurse take?

Choice A reason: Encouraging additional rest periods may help reduce fatigue, but it does not address the underlying issue of improper crutch use. Weakness in both forearms suggests strain from incorrect technique rather than simple overuse. Choice B reason: Watching the client while crutch walking is the correct action because it allows the nurse to assess technique and identify whether improper use is causing forearm weakness. Incorrect crutch placement or weight-bearing can lead to muscle strain and even nerve compression. Observation ensures safety and provides the opportunity for immediate correction. Choice C reason: Demonstrating arm strengthening exercises may be beneficial long-term, but it does not address the immediate problem. The priority is to evaluate and correct crutch technique before recommending strengthening interventions. Choice D reason: Measuring blood pressure in both arms is unrelated to the client’s complaint of forearm weakness. This assessment would not provide information about musculoskeletal strain or crutch use.
