- Blood sample labeling and lab requisitions
- Blood collection tube selection
- Special handling of blood samples
- Capillary (fingerstick, heelstick) blood collection techniques
- Central venous access device blood collection techniques
- Peripheral vein selection and distension
- Peripheral venipuncture techniques
- Appropriate blood collection equipment selection
- Troubleshooting and potential complications
A maximum of 2.5 contact hours can be awarded to online class participants, depending on the number of courses taken within this curriculum.
An optional in-classroom lab for hands-on time is available. The optional lab takes place at Pediatric Home Service in Roseville, Minnesota.
