What is the correct action for obtaining a blood specimen from a newborn via heel stick?

The correct action for obtaining a blood specimen from a newborn via heel stick involves cleansing the puncture site properly to prevent infection and ensure the accuracy of the test results. Cleansing the site with alcohol gauze effectively disinfects the skin, reducing the microbial load and risk of contamination before making the puncture. This step is critical, as newborns have delicate skin and are more susceptible to infection.

Allowing the site to air dry before puncture is an appropriate practice as well; however, it's important to note that the cleansing step must be completed first, and the alcohol should not be left in contact with the skin longer than necessary to avoid affecting lab results. Thus, while air-drying is a relevant step, the priority is the proper cleansing approach to ensure a safe and effective blood specimen collection.
