What are the potential effects of using the wrong size needle for blood collection?

Using the wrong size needle for blood collection can lead to possible hemolysis or difficulty in drawing blood for several reasons. The diameter of the needle is crucial for maintaining the integrity of the blood cells during the collection process. If a needle that is too small is used, the increased friction against the walls of the needle can cause red blood cells to rupture, leading to hemolysis. This is particularly a concern when drawing blood from veins that may be smaller than usual or when a larger volume of blood is required quickly.

Furthermore, an excessively small needle can also create resistance, making it difficult for blood to flow freely. This can result in a prolonged collection time, causing frustration for both the phlebotomist and the patient and may lead to unsuccessful attempts at drawing blood if the flow stops altogether.

The other options, while they may occur in different circumstances, do not accurately capture the direct impact of using the wrong size needle on the blood collection process as effectively as the potential for hemolysis and difficulty in drawing blood. Options related to infection or patient discomfort may result from other practices or techniques during blood collection, but they are not direct consequences of needle size. Thus, the option highlighting hemolysis and difficulty reflects critical aspects of proper blood
