Final answer:
When performing a venipuncture on a patient of average weight, the corrected technique for needle insertion is to insert the needle until it meets resistance.
Step-by-step explanation:
When performing a venipuncture on a patient of average weight, the corrected technique for needle insertion is to insert the needle until it meets resistance. This means that the needle should be inserted until the point where it encounters a slight increase in resistance. This technique ensures that the needle is correctly positioned within the vein and minimizes the risk of complications.
