The nurse is educating a patient's family member about a central venous pressure catheter (CVP). Which statement by the family member best indicates understanding of the purpose of the CVP?
"The catheter will be in position until the heart has a chance to heal."
The catheter will allow the provider to better manage fluid therapy."
"The catheter tip comes to rest inside my brother's left ventricle."
"The catheter will provide multiple IV sites to give intravenous fluid."
The Correct Answer is B
Rationale:
A. While a CVP catheter might be in place for an extended period, its purpose is not directly related to heart healing.
B. The CVP catheter is used to monitor central venous pressure, which helps guide fluid management and assess right heart function.
C. The CVP catheter does not extend into the left ventricle; it is typically positioned in the superior vena cava or right atrium.
D. The CVP catheter may have multiple lumens for administering fluids, but its primary purpose is hemodynamic monitoring, not just providing IV access.

C. Implantable cardioverter-defibrillator (ICD) placement is for managing life-threatening arrhythmias, not directly for treating coronary artery blockages.
D. A circulatory assist device is used in severe cases of heart failure, but it does not address the underlying issue of coronary artery occlusion.
