Before giving a bolus dose via an ongoing IV infusion, what is the nurse's first action?

• A. Ensure that it is compatible with the IV solution being infused.
• B. Pinch the tubing above the infusion port while instilling the bolus.
• C. Instill it into a 50 mL bag of NS and infuse it via a secondary line.
• D. Administer it via a volume-control infusion set with microdrip tubing.

Answer: (A)

Checking compatibility of the bolus medication with the IV solution and line is the first safety step. If the drug is compatible, you can proceed with the bolus in a way that maintains patency and prevents adverse interactions, such as pausing the primary infusion and delivering the dose through a dedicated port with appropriate flushing. If it’s not compatible, you’d need an alternative route or a separate IV line per protocol. The other actions don’t address safety first: pinching the tubing above the port can disrupt flow and isn’t a reliable method for administering the bolus; mixing into a bag of NS and infusing via a secondary line bypasses the compatibility check and can cause unintended effects; using a volume-control or microdrip line doesn’t inherently ensure safe administration and again overlooks compatibility.
