Why is a proper cool-down important for clients on calcium channel blockers?

A proper cool-down is particularly important for clients taking calcium channel blockers to avoid hypotension. Calcium channel blockers are medications that can lead to a decrease in heart rate and blood pressure. Engaging in intense exercise can cause an increased heart rate and elevated blood pressure during activity. However, if the exercise suddenly stops without a proper cool-down, there can be a rapid drop in blood pressure, leading to symptoms of hypotension such as dizziness, lightheadedness, and fainting.

The cool-down period allows the heart rate and blood pressure to gradually return to baseline levels. This is especially crucial for clients on calcium channel blockers, as their ability to respond to changes in heart rate and blood pressure can be compromised. By facilitating a gradual transition, the cool-down helps to maintain stability and reduces the risk of adverse effects associated with abrupt changes in circulation.

The other options, while related, do not address the specific cardiovascular concerns associated with clients on these medications.
