Final answer:
Venipuncture attempts are usually limited to two or three tries per patient. It is essential to minimize attempts to reduce discomfort and prevent complications like phlebitis and catheter-related bloodstream infections.
Step-by-step explanation:
The standard practice for venipuncture does not specify an exact number of attempts allowed per patient but is usually limited to two or three tries. After unsuccessful attempts, it is common for healthcare providers to seek assistance from a more experienced colleague or consider alternative methods for vascular access. Keeping attempts minimal is important to reduce patient discomfort and the risk of complications such as phlebitis, hematoma, or infection.
Moreover, due to the potential for venous catheter-related bloodstream infections (CRBSIs), it is crucial to follow strict aseptic techniques during catheter insertion and maintenance to minimize infection risks. According to the World Health Organization, there are up to 80,000 CRBSIs each year in the US, which can result in significant morbidity and mortality.
