Pharmacology and Intravenous Therapies Practice Exam

When a nurse observes redness, warmth, pain, and slight edema surrounding an IV catheter site, the appropriate initial response is to remove the IV catheter. This action is crucial because these signs and symptoms may indicate phlebitis or the potential for an infection. By removing the catheter, the nurse can help prevent the condition from worsening and reduce the risk of further complications, such as systemic infection.

After the catheter is removed, the nurse can then assess the site more closely for any possible complications and implement further interventions, such as applying a warm compress or notifying the healthcare provider if indicated. Immediate removal helps ensure patient safety and provides an opportunity for proper assessment and management of the affected area.
