Final answer:
The correct action when administering an IV push medication is to flush the peripheral IV prior to administration. This step ensures the patency of the IV line and proper delivery of the medication into the bloodstream.
Step-by-step explanation:
When administering an intravenous push medication through a client's peripheral IV site, the appropriate action by the nurse is to flush the peripheral IV prior to administration. This is an essential step as it helps ensure that the IV line is patent (open and can be used) and prevents any potential compatibility issues between the IV fluids and the medication to be administered. Moreover, flushing the IV line ensures that the medication does not linger in the line and is delivered directly into the bloodstream.
Other options, such as inserting medication into the client's maintenance IV fluids, is done for continuous infusion rather than an IV push. Removing the transparent dressing from the IV site is not necessary unless the site needs to be inspected or the dressing is due to be changed. Aspirating blood from the IV site after administration is not a standard practice for IV medication administration and can increase the risk of complications such as clot formation in the catheter.
