Final answer:
The type of skin puncture device used is dependent on the procedure, skin location, and required puncture depth. Only external skin surfaces are used for sampling, with a device that is safe and non-invasive for the area. A medical item used on intact skin that does not penetrate sterile tissues or mucous membranes is known as a non-critical item.
Step-by-step explanation:
The selection of the type of skin puncture device is determined by the specific procedure and the part of the skin that is going to be sampled. Only external skin surfaces are permitted for this type of testing to maintain sterility and reduce the risk of infection. When selecting a skin puncture device, it is important to choose one that is appropriate for the thickness and location of the skin, as well as the required depth of puncture. The skin puncture device must be non-invasive and safe to use on the specified skin area.
