| Clinical secretary response to IV pump alarm | Notify the nurse if the pump alarm has not been addressed; do not attempt to adjust the pump. |
| Buritrol / Buretrol | A chamber added between the IV bag and tubing to control the volume infused more closely; often used when precise fluid control is needed, especially with children. |
| Gravity-based IV system | IV delivery system in which the bag is hung above the IV site and fluid flows by gravity; the nurse adjusts the roller clamp. |
| Patient-controlled analgesia (PCA) | A system that allows a patient to self-administer preprogrammed doses of IV analgesic within prescribed safety limits. |
| PCA advantage | Can improve the patient's sense of control and reduce anxiety while providing timely pain relief. |
| PCA safety | The pump is programmed so the patient cannot exceed the prescribed maximum dose. |
| Heparin lock / saline lock / PRN adapter | An IV connection device that provides venous access without requiring continuous IV infusion. |
| Purpose of flushing a saline or heparin lock | Keeps the device patent and prevents it from becoming blocked. |
| IV push (IVP) | Medication administered directly into a vein or through an IV port using a syringe. |
| Components of an IV order | Rate of infusion or flow rate, start date, how long the IV is to continue or stop date, and the solution ordered. |
| Flow rate | How fast the ordered IV solution is to be infused into the patient's vein. |
| Common IV flow-rate order | Usually written in mL/hour or cc/hour; nurses may convert this to drops per minute (gtt/min) for gravity systems. |
| gtt/min | Drops per minute; a measurement used to describe an IV infusion rate in a gravity-fed system. |
| Fast IV rate | A faster rate, such as about 150 mL/h, may be ordered for dehydration depending on the patient's condition. |
| Moderate IV rate | A rate of about 75 to 125 mL/h may be used to maintain hydration and electrolyte balance. |

| IV order transcription with CPOE | IV solutions and medications are automatically transmitted to the pharmacy and populate the eMAR and eKardex. |
| Blood transfusion preparation | The patient's blood must be typed and cross-matched to ensure compatible blood is provided. |
