Feedback:
Medications may be given by IV push, also called a bolus. This injection is given in a short period of time and is not intermittent. The IV push only requires a small amount of fluid. Thus, it is often recommended for a client who is at risk for fluid overload. IV piggyback (IVPB) infuses two medications at scheduled intervals. With volume-controlled infusion, solution used to dilute mediations is supplied in a small bag and hung on an IV pole with a volume-control device hung below it. The saline lock is an IV catheter inserted in a vein and left in place, either for intermittent administration of medication or to provide an open line in case of an emergency.

Following a liver biopsy, the nurse should position the client on the right side and apply pressure to the biopsied site (usually the right side) for 4 to 6 hours, using a sandbag or folded bath blanket to help prevent bleeding. The nurse should take vital signs every 15 minutes for 1 hour; every 30 minutes for 4 hours; and then hourly for 8 hours and observe the client closely for signs of bleeding. Hemorrhage may be into the abdomen (watch for signs of shock) or from the puncture site.
