Answer:
Step-by-step explanation:
The nurse would provide oxygen to a client with chest pain, as the heart may be getting insufficient oxygen as a result of occluded coronary vessels. The nurse would also assess the client's vital signs, obtain a 12-lead EKG, and auscultate heart sounds to determine rhythm changes related to cardiac ischemia. The nurse would need to draw blood for evaluation of cardiac enzymes. Changes in the levels of these enzymes (including troponin, creatine kinase, and myoglobin) can indicate damage to heart tissue. Nitroglycerin is administered to promote coronary vasodilation.
