The nurse assesses the client’s peripheral intravenous (IV) site and observes a red streak on the forearm that is warm to the touch. Which action should the nurse perform first?

Choice A reason: Assessing vital signs is important when infection or systemic involvement is suspected; however, the priority is to stop the source of injury. A red streak and warmth along the vein indicate phlebitis, which requires immediate intervention to prevent progression. Vital signs can be assessed after the offending catheter is removed. Choice B reason: Applying a cool compress may help relieve inflammation and discomfort associated with phlebitis, but it does not address the underlying cause. Supportive measures should only be implemented after the IV catheter has been discontinued to prevent further vascular irritation. Choice C reason: A red streak and warmth along the vein are classic signs of phlebitis. The first and most important action is to remove the IV catheter to prevent further inflammation, tissue damage, or infection. Removing the source of irritation is the priority intervention according to safety and nursing standards. Choice D reason: Notifying the healthcare provider may be necessary if complications develop or further treatment is required. However, this is not the first action. Immediate nursing intervention is required to stop the progression of phlebitis before escalation of care.
