After placing the tubing in the vacoliter, what is the next step?

The appropriate next step after placing the tubing in the vacoliter is to squeeze the chamber to fill it halfway. This action is crucial because it helps to ensure that the medication is drawn into the tubing effectively and that the air is expelled from the system. This pre-filling step is essential for achieving an accurate dosage and minimizing the risk of introducing air into the patient's bloodstream, which could lead to complications.

Once the chamber is filled, healthcare professionals can proceed to administer the medication or check for proper fluid flow, making this action a fundamental part of the preparation process prior to the actual administration of the drug. It's an important step in ensuring the safe and effective delivery of intravenous medications.
