Correct Answer: C

Rationale: Pain that worsens with breathing in can indicate pleuritic chest pain, which is non-cardiac in nature. This specific question helps in differentiating non-cardiac causes from cardiac causes of chest pain, as cardiac pain typically does not worsen with breathing.

Correct Answer: B

Rationale: After being transferred from the CCU to the general medical unit with cardiac monitoring, the client with MI is typically prescribed bathroom privileges and self-care activities. This allows for gradual recovery and mobility while still being closely monitored, promoting the client's overall well-being and independence.

Correct Answer: D

Rationale: Fresh strawberries, steamed vegetables, and baked fish constitute a meal low in saturated fats and cholesterol, making it a suitable choice for a client with CAD. This meal aligns with dietary recommendations to support heart health and manage CAD.

Correct Answer: B

Rationale: When a client with CAD experiences chest pain, it indicates myocardial ischemia. The nurse should have the client stop the activity and lie back down in bed to reduce the heart's oxygen demand, decrease myocardial workload, and prevent further ischemia. This action helps in improving blood flow to the heart and can potentially alleviate the chest pain.

Correct Answer: D

Rationale: A slight increase in blood pressure without significant symptoms indicates that the client is tolerating the activity. In this scenario, a mild increase in blood pressure without other symptoms is a positive sign of tolerance to ambulation despite the underlying condition of bacterial endocarditis.
