Which of the following statements is true about Parkinson disease (PD)?

Choice A reason: Use of a commode close by to where the client spends most of his time can reduce the distance and time required for the client to reach the toilet, and thus prevent accidents and embarrassment. It can also promote the client's independence and dignity.

Choice B reason: Development of a toileting schedule can help the client to establish a routine and habit of voiding at regular intervals, and thus prevent the bladder from becoming too full or overactive. It can also reduce the risk of urinary tract infections and skin breakdown.

Choice C reason: Use of an external catheter is not recommended for older adults with dementia, as it can cause irritation, infection, and obstruction of the urinary tract. It can also increase the client's confusion and agitation, and interfere with his mobility and comfort.

Choice D reason: Bladder diary to be completed by the client's wife is not a direct intervention to manage the incontinence, but rather a tool to assess the pattern and severity of the problem. It can help the nurse to identify the possible causes and triggers of the incontinence, and to evaluate the effectiveness of the interventions. However, it may not be feasible or reliable for the client's wife to complete the diary, as she may have other responsibilities or difficulties in observing and recording the client's urinary habits.

Choice A reason: This is incorrect because using smooth muscle relaxants is not the most important aspect of care for the nurse to maintain when assisting an older client with urinary incontinence. Smooth muscle relaxants are medications that can relax the bladder and reduce the urge to urinate, but they can also cause side effects such as dry mouth, constipation, or blurred vision. They are not suitable for all types of urinary incontinence, and they should be used with caution and under medical supervision.

Choice B reason: This is incorrect because availability of protective rubber garments is not the most important aspect of care for the nurse to maintain when assisting an older client with urinary incontinence. Protective rubber garments are devices that can prevent urine leakage and protect the skin and clothing, but they can also cause skin irritation, infection, or odor. They are not a cure for urinary incontinence, and they should be used as a last resort or in combination with other interventions.

Choice C reason: This is incorrect because using indwelling urinary catheters is not the most important aspect of care for the nurse to maintain when assisting an older client with urinary incontinence. Indwelling urinary catheters are tubes that can drain urine from the bladder and collect it in a bag, but they can also cause complications such as urinary tract infections, bladder spasms, or trauma. They are not recommended for long-term use, and they should be used only when other methods have failed or are contraindicated.

Choice D reason: This is correct because maintaining an attitude that is respectful and positive about resolving the problem is the most important aspect of care for the nurse to maintain when assisting an older client with urinary incontinence. Urinary incontinence can cause embarrassment, shame, isolation, or depression in older clients, and they may be reluctant to seek help or comply with treatment. The nurse should respect the client's dignity, privacy, and preferences, and provide education, support, and encouragement. The nurse should also assess the underlying causes and contributing factors of urinary incontinence, and implement individualized and evidence-based interventions.
