How often should the IV site be checked?

• A. Every 2 hours
• B. Every 4 hours
• C. Every 6 hours
• D. Every 12 hours

Answer: (B)

Regular IV site assessment is essential to detect problems early and keep the line functioning. For a routine peripheral IV, checking the site about every four hours is standard practice. This interval helps catch common issues like infiltration, phlebitis, infection, or catheter dislodgement in a timely way without overburdening care needs. If the infusion is irritating or vesicant, if the patient reports pain, or if you see redness, swelling, drainage, or a slow or stopped flow, increase the frequency of checks to more frequent intervals (even hourly) or as your unit policy directs. Checking less often, like every six or twelve hours, risks missing early signs of complications.
