When teaching a client with Parkinson's disease, which rationale for the prescription of carbidopa-levodopa should the nurse include?

Choice A reason: Reviewing written and verbal instructions for a reduced sodium diet is not directly related to the management of primary open-angle glaucoma (POAG). While a healthy diet can contribute to overall well-being, dietary sodium does not have a significant impact on intraocular pressure or glaucoma management. Therefore, this intervention does not directly address the client's primary condition of POAG.

Choice B reason: Teaching strategies for aseptic administration of the eye drops is a critical intervention for clients with POAG. Proper administration of ophthalmic drops is essential to avoid contamination and infection. Aseptic techniques include washing hands before administering the drops, avoiding touching the dropper tip to any surface (including the eye), and ensuring that the dropper cap is replaced tightly after use. These measures help maintain the sterility of the medication and prevent complications such as eye infections, which can exacerbate the client's condition.

Choice C reason: Describing how the use of the eye drops will help improve peripheral vision is not entirely accurate in the context of POAG. The primary goal of ophthalmic drops for POAG is to lower intraocular pressure and prevent further damage to the optic nerve, thereby preserving the remaining vision. These drops do not typically improve peripheral vision that has already been lost. Educating the client with accurate information about the purpose and benefits of the drops helps set realistic expectations and encourages adherence to the treatment regimen.

Choice D reason: Teaching the client to apply pressure over the inner eye corner (punctal occlusion) after administering eye drops is an important intervention. Punctal occlusion helps prevent the medication from draining into the tear duct and being absorbed systemically. This technique increases the contact time of the medication with the eye, enhancing its effectiveness and reducing potential systemic side effects. Clients should be instructed to gently press the inner corner of the eye for a few minutes after instilling the drops to ensure maximum benefit.

Choice E reason: Explaining the need to continue eye drops for the rest of their life is essential for clients with POAG. Glaucoma is a chronic condition that requires lifelong management to control intraocular pressure and prevent progression of the disease. Discontinuing the medication can lead to elevated intraocular pressures and irreversible vision loss. Clients should understand the importance of adherence to their prescribed treatment regimen and the lifelong commitment to managing their condition to preserve their vision and quality of life.

Choice A reason: Thick skin plaques topped by silvery white scales are characteristic findings in psoriasis vulgaris itself and do not indicate overexposure to PUVA treatment. These plaques are a result of rapid skin cell turnover and are typically the target of treatment, not a side effect of overexposure.

Choice B reason: The requirement for sunglasses because sunlight hurts the eyes is not a specific indication of overexposure to PUVA treatment. While PUVA therapy can increase sensitivity to light, the use of sunglasses is a preventive measure and does not necessarily indicate overexposure.

Choice C reason: Brown, rough, greasy, wart-like papules on the face suggest the presence of seborrheic keratosis or another benign skin condition, not overexposure to PUVA treatment. These lesions are unrelated to the therapy and do not serve as an indicator of overexposure.

Choice D reason: Tenderness upon palpation and generalized erythema are signs of overexposure to PUVA treatment. Overexposure can lead to phototoxic reactions, resulting in skin irritation, redness, and tenderness. These symptoms indicate that the client has received too much UV radiation during the treatment, leading to an adverse reaction.
