Which signs necessitate the temporary discontinuation of an infusion and relocation of an IV catheter?

The signs that necessitate the temporary discontinuation of an infusion and relocation of an IV catheter include the characteristics described in the correct choice. When the insertion site is pale, cool to the touch, and edematous, it indicates potential complications such as infiltration or phlebitis. These conditions can compromise the integrity of the infusion and pose a risk of tissue damage if not addressed promptly.

Infiltration occurs when IV fluid leaks into the surrounding tissue, leading to swelling and a cooler temperature at the site. Phlebitis involves inflammation of the vein, which may also present with similar symptoms, especially when accompanied by pain. Recognizing these signs is crucial for the safe management of IV therapy, as they require immediate action to prevent further complications and ensure patient safety.

The other choices, while they may indicate some issues, do not present the same level of concern as the symptoms described in the correct choice. For example, a warm site without visible symptoms might suggest normal function, and dried blood on the dressing may not necessarily indicate a serious problem if no significant symptoms are present. Lack of drainage does not inherently require catheter removal unless accompanied by distressing signs. Thus, understanding the implications of these specific indicators is vital for maintaining effective IV fluid therapy
