What is a common traditional practice not supported by evidence?

• A. The belief that large-bore IV needles are needed for blood administration.
• B. Using digital documentation rather than charting in real time.
• C. Assuming that patient education is unnecessary for some procedures.
• D. Relying solely on senior staff without considering evidence

Answer: (A)

The key idea here is that many nursing practices linger from tradition rather than solid evidence, and choosing the right equipment should be guided by what actually improves safety and outcomes. For blood administration, the belief that you must use a large-bore IV is a classic example of a tradition that isn’t consistently supported by evidence. In most adult transfusions, an 18- or 20-gauge catheter is adequate, and the speed of transfusion is more about the infusion setup and the patient’s condition than simply using the biggest needle. Only in specific, high-urgency situations (such as a massive transfusion) would a larger bore be considered, and even then choices are guided by protocol rather than habit. Using a larger needle when it isn’t necessary can cause more vein trauma and discomfort without providing a real clinical benefit.

So, this choice stands out as a common traditional practice not backed by evidence, compared with practices that align with current evidence such as ensuring real-time documentation, providing patient education, and basing decisions on evidence rather than just relying on senior staff.
