A client receives a 12-lead electrocardiogram (ECG) and asks the practical nurse (PN) what the test is measuring. Which information should the PN explain about this diagnostic test?

Choice A reason: Smoking two packs of cigarettes a day is highly significant in planning the client's rehabilitation following a myocardial infarction. Smoking is a major risk factor for cardiovascular disease, and continuing to smoke can significantly hinder recovery and increase the risk of future cardiac events. Addressing this behavior is crucial for improving the client's long-term health outcomes. Smoking cessation should be a primary focus of the rehabilitation plan, and the client should be provided with resources and support to quit smoking, such as counseling, nicotine replacement therapy, or medications.
Choice B reason: Expressing a desire to change one's lifestyle is a positive and encouraging sign. It indicates the client's motivation to adopt healthier habits, which is essential for successful rehabilitation. However, while this is important, the immediate focus should be on addressing specific risk factors, such as smoking, that have a direct and significant impact on the client's recovery and future health. The desire to change is a valuable component of the rehabilitation process, but it should be coupled with targeted interventions to address critical behaviors like smoking.
Choice C reason: Drinking 1 to 2 glasses of red wine daily may have both positive and negative health implications. Moderate alcohol consumption has been suggested to have some cardiovascular benefits, but it can also pose risks, especially if not monitored. While this information is relevant to the client's overall lifestyle, it is not as immediately critical as addressing smoking, which has a well-documented and direct impact on cardiovascular health. The client's alcohol consumption can be discussed as part of the broader lifestyle changes during rehabilitation.
Choice D reason: Walking four city blocks to work each day indicates a level of physical activity that is beneficial for cardiovascular health. Encouraging regular physical activity is an essential part of the rehabilitation process. However, compared to the impact of smoking, this information is less critical in the immediate planning of the client's rehabilitation. The focus should be on eliminating harmful behaviors like smoking, while also promoting continued and possibly increased physical activity as part of a comprehensive rehabilitation plan.

Choice A reason: Placing the food and utensils in the client's left visual field and leaving him alone does not address the underlying issue of the visual field deficit. While it may temporarily solve the problem of the client eating only the food on the left side, it does not encourage the client to adapt to or compensate for the right homonymous hemianopsia. The goal of rehabilitation is to help the client develop strategies to manage their condition independently, and this approach does not foster such skills.
Choice B reason: Feeding the client foods that are on the right side of his visual field is not the most effective approach, as it does not promote the client's independence or help them adapt to their visual field deficit. While it ensures the client consumes the food on the right side, it does not teach the client to compensate for their hemianopsia, which is an essential aspect of their rehabilitation.
Choice C reason: Reminding the client to look all over the tray to view and eat all the foods provided is the best approach. This action helps the client become more aware of their visual field deficit and encourages them to develop the habit of scanning their environment. Teaching the client to consistently look around their entire visual field promotes independence and helps them adapt to daily activities despite their condition. This strategy supports the goal of rehabilitation, which is to enhance the client's ability to manage their visual impairment independently.
Choice D reason: Prompting the client to rotate his plate to see foods on the right side of the tray is a practical solution, but it does not address the broader need for the client to learn to scan their environment. While rotating the plate may temporarily help the client access the food on the right side, it does not encourage the development of compensatory strategies for the visual field deficit. Encouraging the client to look all over the tray is a more effective approach for long-term adaptation and independence.
