Question: Tina is transferred to the cardiac catheterization laboratory. While the team prepares for percutaneous coronary intervention, the nurse quickly explains the sequence of events occurring in the myocardium. Tina asks why the team is moving "so fast" when the pain only started less than an hour ago. Which explanation should the nurse provide? Heart muscle can tolerate a short loss of blood flow without lasting harm. Heart muscle can be permanently damaged if blood flow is not restored quickly. Heart muscle damage will not occur if chest pain eases for a short time. Heart muscle can remain unharmed if telemetry changes are limited early on. Need Assignment Help?
