Correct Answer is A
Explanation
A. Work together to see how they can incorporate healthier choices into the foods enjoyed:
This approach emphasizes collaboration between the nurse and the client, focusing on finding ways to incorporate healthier food choices into the client's diet while considering their food preferences and cultural background. By working together, the nurse can help the client identify suitable substitutions, portion control strategies, and meal planning techniques that align with the dietary recommendations for coronary heart disease. This approach promotes active participation, empowers the client to make informed decisions, and increases the likelihood of long-term adherence to the dietary plan.
B. Tell the client if they do not change their diet, they are going to have a myocardial infarction:
This approach uses fear tactics or negative consequences to motivate behavior change, which is generally not recommended in healthcare settings. Fear-based strategies may lead to increased anxiety, stress, or resistance in the client, ultimately hindering motivation and adherence to the dietary plan. Positive reinforcement, education, and collaborative goal-setting are more effective in promoting behavior change and improving adherence to lifestyle modifications.
C. Give the client a list of foods to choose from:
Providing a list of foods can be a helpful tool in guiding food choices and promoting a balanced diet. However, this approach may not address the client's individual preferences, cultural considerations, or practical challenges in implementing dietary changes. Without personalized guidance and support, the client may struggle to navigate food options effectively and may experience difficulties in adhering to the dietary recommendations.
D. It is okay to cheat because of the medications:
Encouraging cheating or deviating from the dietary plan due to medications undermines the importance of dietary modifications in managing coronary heart disease. It is essential to emphasize the significance of following a heart-healthy diet and lifestyle, as medications alone may not be sufficient to manage the condition effectively. Providing education on medication adherence and dietary guidelines, along with ongoing support, helps reinforce the importance of consistent dietary habits in promoting cardiovascular health.
Correct Answer is C
Explanation
A. 120/80 mm Hg or lower:
This blood pressure range is considered normal or optimal for most adults. However, for individuals diagnosed with hypertension, the goal is typically to reduce blood pressure to below 140/90 mm Hg, as maintaining normal blood pressure is not considered a goal for hypertension treatment unless specifically indicated based on individual circumstances.
B. Average of two BP readings of 150/80 mm Hg:
A blood pressure reading of 150/80 mm Hg is elevated and indicates hypertension, especially if consistently elevated across multiple readings. The goal of hypertension treatment is to lower blood pressure to below 140/90 mm Hg, so an average of 150/80 mm Hg would not be considered the goal of treatment.
C. 140/90 mm Hg or lower:
This blood pressure range is commonly recommended as the goal of treatment for individuals with hypertension who otherwise enjoy good health. It represents a balance between effective blood pressure control and minimizing the risk of side effects or complications associated with overly aggressive treatment.
D. 156/96 mm Hg or lower:
While a blood pressure reading of 156/96 mm Hg is elevated and indicates hypertension, the goal of treatment is typically to reduce blood pressure to below 140/90 mm Hg rather than targeting a specific numeric value below 156/96 mm Hg.
