All the devices in the options are considered contaminated which are
Used IV tubing with NO visible blood
A used needle
A syringe detached from the used needle
Used IV tubing with visible blood
- According to the CDC on safe injection practices, Once injection supplies and materials have been used , they should be discarded because they have potentials for contamination.
- We cannot rule out the fact that Pathogens found in human immunodeficiency virus (HIV) as well as Hepatitis can be present to cause infection both in the presence and absence of blood.
- This is to buttress the fact that some bacteria and other microbes can be present which we cannot see physically and because blood is not visible in a used syringe or IV tubing does not mean the item is pathogen free.
It is therefore pertinent that:
- Needles or syringes should be used for only one patient and discarded immediately after use.
- Used IV tubing with visible blood or no visible blood should be discarded and never reused.
