The client has a history of recurrent transient ischemic attack (TIA). Based upon this history the nurse is most concerned about the client's potential to develop:
 
  1. Renal failure
  2. Gangrene
  3. Myocardial infarction
  4. Stroke

Question 2

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.

Answer to Question 1

Correct Answer: 4
Rationale 1: Renal failure would result from atherosclerotic changes in the renal artery.
Rationale 2: Gangrene may occur if atherosclerosis reduces blood flow to extremities.
Rationale 3: Myocardial infarction results from atherosclerosis of the coronary arteries.
Rationale 4: Transient ischemic attacks may result from atherosclerosis of the cerebral vessels. Continued development of this atherosclerosis may result in stroke.

Answer to Question 2

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.
