Final answer:
The primary IV tubing for a patient receiving a 0.9% NaCl solution should typically be changed every 72 hours, according to the Infusion Nurses Society standards, but this may vary based on hospital policies and the specific type of treatment. The correct option is B.
Step-by-step explanation:
The question is regarding the frequency at which primary intravenous (IV) tubing should be changed when administering a 0.9% NaCl solution to a patient. IV tubing is an essential component of a patient's treatment regime, and its maintenance is crucial for preventing infections. The timing for IV tubing changes can vary based on the type of solution being delivered and institutional policies. However, according to the Infusion Nurses Society (INS) standards, primary IV tubing used for continuous infusions, such as 0.9% NaCl, should typically be changed every 96 hours (or every 4 days), which is equivalent to conducting a change every 72 hours when considering added safety margins.
It is also important to note that some institutions may have different protocols, and factors such as the type of medication infused or patient-specific conditions could necessitate more frequent changes. For instance, if the IV system is used to deliver blood, blood products, or lipid emulsions, the tubing must be changed more frequently—often every 24 hours. Therefore, while 72 hours is generally accepted as the standard interval for changing primary IV tubing for 0.9% NaCl, medical professionals should always follow their facility's policies and the latest evidence-based guidelines to ensure optimal patient care and safety.
