Rationale: Stable angina is typically triggered by physical exertion or emotional stress and is predictable in its frequency, intensity, and duration. In contrast, unstable angina is characterized by angina episodes that are unexpected, more severe, prolonged, and can occur at rest. Understanding these differences can help healthcare providers assess and manage angina episodes effectively, ensuring appropriate interventions are implemented promptly based on the type of angina present.

Correct Answer: D

Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.

Correct Answer: A

Rationale: The correct answer is to decrease salt and fat intake and limit alcohol intake. These dietary changes can help manage angina by reducing the workload on the heart and preventing further plaque buildup in the arteries. Choices B, C, and D are incorrect as dietary restrictions for angina typically involve reducing salt, fat, and alcohol intake, rather than increasing sugar or cholesterol intake.

Correct Answer: D

Rationale: Removing the nitrate patch for 8 hours each day is essential to prevent the body from developing tolerance to the medication. By allowing the body to have a drug-free period, the effectiveness of the medication is maintained over time. This practice helps in ensuring that the nitrate patch continues to provide its intended therapeutic effects without diminishing its efficacy. Therefore, it is important for the client to adhere to the prescribed schedule of removing the patch for 8 hours daily to optimize the treatment outcomes.
