A client with a history of atrial fibrillation is prescribed warfarin. Which laboratory value should the nurse monitor to assess the medication’s effectiveness?

Choice A reason: Assisting with mobility and fall prevention is critical in Parkinson’s disease, as bradykinesia and rigidity increase fall risk. Physical therapy and assistive devices enhance safety, reducing injury risk, making this the priority intervention to maintain functional independence and prevent fractures.

Choice B reason: High-protein meals may interfere with levodopa absorption in Parkinson’s, worsening symptoms. Mobility assistance is the priority, as falls are a leading cause of injury, requiring immediate intervention to ensure safety, making dietary protein secondary to physical support.

Choice C reason: Restricting fluid intake is inappropriate, as hydration prevents constipation in Parkinson’s. Mobility and fall prevention are critical, as motor symptoms increase injury risk. Assisting with mobility addresses the primary functional challenge, making fluid restriction irrelevant to priority care.

Choice D reason: Promoting social isolation worsens depression in Parkinson’s, a common comorbidity. Mobility assistance is the priority, as falls due to motor impairment are a significant risk, requiring immediate intervention to ensure safety, making social isolation counterproductive to care.

Choice A reason: Rinsing the mouth after using a corticosteroid inhaler prevents oral candidiasis, a common side effect from residual steroid deposition. This ensures safe asthma management, as fungal infections compromise adherence and health, making it the priority teaching point for proper inhaler use.

Choice B reason: Using the inhaler only during asthma attacks applies to rescue inhalers, not maintenance corticosteroids, which are used daily. This is incorrect, as rinsing the mouth is essential for corticosteroid inhalers to prevent oral thrush, ensuring safe and effective asthma control.

Choice C reason: Storing inhalers in a refrigerator is unnecessary and may degrade some medications. Room-temperature storage is standard. Rinsing the mouth after corticosteroid inhaler use is critical to prevent oral candidiasis, making it the priority teaching point for asthma management.

Choice D reason: Shaking the inhaler only once may be insufficient for proper aerosolization in some devices. Rinsing the mouth after corticosteroid inhaler use is the priority, as it prevents oral thrush, a significant side effect, ensuring safe and consistent asthma therapy.
