A client having a stress test exhibits an increased heart rate and stronger cardiac contraction but no chest pain. What is occurring to this client's coronary arteries?
1. Constriction
2. Dilation
3. Vasospasm
4. No change is occurring.
Correct Answer: 2
Rationale 1: Constricting of the coronary arteries would lead to ischemia and chest pain.
Rationale 2: An increased heart rate and stronger cardiac contraction indicate that dilation is occurring.
Rationale 3: Experiencing a vasospasm of the coronary arteries would lead to ischemia and chest pain.
Rationale 4: No change in the coronary arteries would possibly lead to ischemia and chest pain.
Global Rationale: An increased heart rate and stronger cardiac contraction indicate that dilation is occurring. Constricting of the coronary arteries, vasospasm, and no change would lead to ischemia and chest pain.
