An older adult client with a long history of chronic obstructive pulmonary disease (COPD) is admitted with progressive shortness of breath and a persistent cough. The client is anxious and is complaining of a dry mouth. Which intervention should the nurse implement?

A. Carefully cleans and peels all fresh fruit and vegetables:
While cleaning and peeling fresh fruits and vegetables may contribute to food safety, it is not a specific indication of adherence to the DASH eating plan.

B. Uses only lactose-free dairy products:
The DASH eating plan encourages the consumption of low-fat or fat-free dairy products. Using lactose-free dairy products may be necessary for individuals with lactose intolerance, but it is not a specific behavior related to the DASH plan.

C. No longer includes grains in the daily diet:
The DASH eating plan includes whole grains as part of a balanced diet. Eliminating grains altogether is not consistent with the DASH plan, which encourages the consumption of whole grains.

D. Enjoys fat-free yogurt as an occasional snack food:
This is the correct answer. The DASH eating plan recommends the inclusion of low-fat or fat-free dairy products as part of a heart-healthy diet. Choosing fat-free yogurt as an occasional snack aligns with the principles of the DASH plan, which emphasizes low-fat dairy options.

A. Eat a diet high in carotene:
While a healthy diet is important for overall well-being, there is no evidence to suggest that a diet high in carotene specifically prevents or treats glaucoma. The focus in glaucoma management is on intraocular pressure control.

B. Wear prescription glasses:
Prescription glasses may be beneficial for addressing refractive errors, but they do not specifically address the management of glaucoma. The client's concern about driving through a tunnel is more likely related to changes in peripheral vision associated with glaucoma.

C. Avoid frequent eye pressure measurements:
This is not the most important instruction. Monitoring intraocular pressure is a crucial aspect of glaucoma management, and the frequency of measurements is determined by the healthcare provider. Regular monitoring helps assess the effectiveness of treatment and disease progression.

D. Maintain the prescribed eye drop regimen:
This is the correct answer. The most important instruction for the client is to adhere to the prescribed eye drop regimen. Medications, often in the form of eye drops, are commonly used to lower intraocular pressure and manage glaucoma. Consistent use of prescribed medications is critical for controlling the condition and preventing further vision loss.
