What is one sign that may indicate a complication from a CVAD?

• A. Improved blood flow
• B. Elevated respiratory rate
• C. Clear and stable vital signs
• D. Increased appetite

Answer: (B)

An elevated respiratory rate can be a significant indicator of a complication arising from the use of a central venous access device (CVAD). When complications occur, such as infection, thrombosis, or pneumothorax, the body may react by increasing the respiratory rate as it attempts to meet its oxygen needs and compensate for any distress. This physiological response is often seen when there is an underlying issue affecting the lungs or circulation, indicating that further assessment and intervention may be necessary.

In contrast, improved blood flow, clear and stable vital signs, and increased appetite do not typically suggest complications associated with a CVAD. Improved blood flow generally indicates that the CVAD is functioning properly, while clear and stable vital signs suggest the patient's condition is stable. An increased appetite is typically a sign of good health and recovery, rather than a complication. Therefore, elevated respiratory rate serves as a pertinent red flag that requires further evaluation in the context of CVAD management.
