What is a common complication during PAC insertion that requires attention?

1. Hypotension

2. Catheter misplacement

3. Hypervolemia

4. Bradycardia

The correct answer is: Catheter misplacement

The correct response focuses on catheter misplacement as a common complication during Pulmonary Artery Catheter (PAC) insertion that requires immediate attention. Proper positioning of the PAC is crucial because misplacement can lead to severe complications such as cardiac arrhythmias, pulmonary vascular injury, or perforation of the cardiac chambers. During the procedure, if the catheter is not positioned appropriately within the pulmonary artery, it can end up in unintended locations, such as the right ventricle or even the left atrium, depending on the insertion technique and anatomical variations. Identifying and correcting catheter misplacement early can prevent worsening outcomes and ensure accurate hemodynamic monitoring, which is critical in managing patients who are often in critical condition. While hypotension, hypervolemia, and bradycardia can occur during or after PAC insertion, they are not as specific to the process of catheter placement itself. These other conditions can arise due to a variety of factors related to the patient's underlying health or response to anesthesia rather than directly resulting from a technical error during insertion. Thus, catheter misplacement stands out as a complication that directly relates to the procedure being performed.
