Try 3 fluid & electrolytes questions
A 68-year-old client was admitted 2 days ago following a mild stroke affecting the left side. On admission, the client was independent with all activities of daily living (ADLs). Today, the nurse observes that the client is alert and oriented ×3, with 3/5 strength in the left upper and lower extremities and intact cognition. The client is attempting to dress himself but moves slowly and has difficulty pulling his left sleeve over his shoulder. The health care provider has cleared the client for ADL participation. The client states, "I can do this, just give me a moment." What is the priority nursing action?
