Final answer:
If the next TPN bag is not ready, a healthcare provider should use a sterile IV solution to maintain line patency. For medication, such as KCl needed for hypokalemia, proper dilution calculations must be performed following a physician's orders. Safety protocols should be strictly followed.
Step-by-step explanation:
If a client is receiving total parenteral nutrition (TPN) through a central venous access device and the next bag of solution is not ready, the healthcare provider should not leave the line without solution, as this could lead to complications, including air embolism or clotting of the line. Instead, a standard protocol involves the use of an IV bag of sterile solution to maintain line patency until the TPN solution is available. In some situations, healthcare staff may need to prepare a specific medication or electrolyte solution, such as a dilution of potassium chloride (KCl). In this case, an aide or a nurse must perform a dilution calculation to get the correct concentration from a stock solution using a syringe. The solution is then administered to the patient according to physician orders to treat conditions like hypokalemia. At all times, it is crucial that health professionals follow safety guidelines and hospital protocols to ensure the patient's safety.
