Which of the following is a common complication of venipuncture?

Infection is a common complication of venipuncture due to the invasive nature of the procedure, which involves puncturing the skin to access a vein. During this process, there is a possibility of introducing bacteria into the body, particularly if proper aseptic techniques are not followed. This can lead to local infections at the puncture site or, in more severe cases, bloodborne infections. Maintaining a sterile environment, using clean techniques, and ensuring that both the technician and the equipment are properly sanitized are crucial for minimizing the risk of infection.

Other complications such as headache, nausea, and diarrhea are not typically associated directly with venipuncture. While patients may experience anxiety or discomfort, these symptoms do not stem from the procedure itself and are not common complications of the act of drawing blood. Understanding the specific risks associated with venipuncture helps in taking the necessary precautions to ensure patient safety.
