Cardiac-Vascular Nursing (CVRN) Practice Exam

What should the cardiac-vascular nurse do first for a patient experiencing numbness and pain in the right hand after cardiac catheterization?

1. Call the physician

2. Perform Allen's test

3. Reduce the pressure on the puncture site

4. Use the Doppler to assess for pulse signals

The correct answer is: Reduce the pressure on the puncture site

In the scenario presented, the primary concern is ensuring adequate blood flow to the extremity following a cardiac catheterization. When a patient experiences numbness and pain after the procedure, it can indicate potential complications, such as compromised circulation to the limb due to pressure or hematoma formation at the puncture site. By reducing the pressure on the puncture site, the cardiac-vascular nurse can help alleviate any restrictions in blood flow. This action is critical as it may relieve any immediate tension that is affecting circulation and reduce the risk of serious complications, such as limb ischemia. Ensuring proper perfusion is essential, and addressing pressure issues can be a key step in protecting the patient's hand. While options such as performing Allen's test or using Doppler to assess pulse signals are important in assessing circulation, these measures typically follow the immediate action of alleviating pressure if that is deemed to be the source of the problem. Calling the physician may also be necessary, but it is prudent to first address the immediate concern by reducing pressure to assess whether the symptoms improve. This prioritization of immediate intervention reflects sound nursing judgment in addressing potential circulatory issues that may affect limb viability.
