Which method is most appropriate for monitoring exercise intensity in a hypertensive client taking a beta-blocker?

The talk test is an effective method for monitoring exercise intensity, particularly for hypertensive clients who are taking beta-blockers. Beta-blockers can diminish the heart's ability to respond to increases in exercise intensity, which may make heart rate an unreliable indicator of exertion. Since these medications can lower a person's maximal heart rate and affect heart rate responses, using a heart rate monitor could lead to misleading results about the client's exercise intensity.

The talk test, on the other hand, provides a practical and straightforward way to gauge intensity based on conversational ability. During moderate-intensity exercise, a person should be able to talk but not sing, whereas at higher intensities, speaking will become more difficult. This method encourages clients to listen to their bodies and adjust their intensity based on their ability to hold a conversation.

Other options like the perceived exertion scale could also be useful, but the talk test is particularly advantageous for those on beta-blockers, as it emphasizes qualitative assessment rather than quantitative measures that may be influenced by medication.
