How frequently should IV site assessment occur in adult inpatients?

• A. Every 2 hours
• B. Only on admission
• C. At least every 4 hours
• D. Daily

Answer: (C)

Regular IV site assessment is about spotting problems like infiltration, phlebitis, or infection early so patient safety and IV therapy effectiveness are maintained. For adult inpatients, the baseline standard is to check the IV site at least every 4 hours. This interval strikes a balance between monitoring needs and practical workload, allowing prompt detection of evolving issues. More frequent checks are needed if the patient has high-risk factors (fragile or small veins, use of irritant or vesicant medications, poor IV flow). Checking only on admission would miss problems developing after that initial snapshot, and checking daily is too lax for ongoing IV therapy.
