The post-myocardial infarction client asks the nurse about return to exercise. What information should the nurse give this client?
1. It is better to exercise when it is cold.
2. Environmental temperatures have little impact on cardiac function.
3. Avoid exercise when the weather is hot or cold.
4. Hot temperatures increase peripheral blood vessel contraction.
Correct Answer: 3
Rationale: The nurse should advise the client to avoid exercise in hot or cold weather as these extremes of temperature increase the workload on the heart. Cold temperatures increase peripheral blood vessel contraction and therefore peripheral vascular resistance, making it more difficult for the heart to circulate blood. Hot temperatures decrease systemic vascular resistance by dilating peripheral vessels. This decrease makes the heart rate increase, thereby increasing the heart's workload.
