During an assessment, what might a nurse note about a client with unstable angina?

In the context of unstable angina, the symptoms are characterized by chest discomfort that typically increases in intensity and frequency. Unlike stable angina, where pain occurs predictably with exertion and is relieved by rest or medication, unstable angina presents as pain that can occur at rest or with minimal exertion. This discomfort may progress over time, representing an increased risk of myocardial infarction.

The nature of unstable angina is particularly concerning because it indicates a change in the pattern of angina, which may suggest the presence of a more severe underlying issue, such as atherosclerotic plaque rupture, leading to myocardial ischemia. The fact that the discomfort worsens reflects the instability of the angina, making it a medical emergency that typically requires immediate intervention to prevent further cardiac complications.

In contrast, the other options describe symptoms or patterns that are not characteristic of unstable angina, highlighting the distinctive nature of this condition in clinical presentations.
