Which of the following techniques is required for performing a venipuncture?

Using a sterile needle and technique is essential for performing a venipuncture because it helps prevent infections and ensures patient safety. When collecting blood samples, it's critical that the needle is sterile to avoid introducing pathogens into the bloodstream. The use of appropriate techniques, including maintaining a clean environment and proper hand hygiene, significantly reduces the risk of contamination and complications.

In addition, employing sterile techniques includes not only using a sterile needle but also preparing the skin with antiseptics prior to the puncture to eliminate surface bacteria. This foundational aspect of venipuncture is crucial for promoting better patient outcomes and maintaining the integrity of the samples being collected.
