Which signs are most consistent with IV phlebitis?

• A. Redness, tenderness, warmth along the vein with a red streak or palpable cord
• B. Swelling of the ankle
• C. Cough and wheeze
• D. Nausea and vomiting

Answer: (A)

IV phlebitis involves inflammation at the vein where the IV is placed. The most consistent signs are localized along that vein: redness, tenderness, and warmth, often with a red streak or a palpable cord indicating irritation and possibly superficial thrombophlebitis. These symptoms reflect inflammation of the vein itself and its immediate surroundings. Other options don’t fit because swelling of the ankle suggests generalized edema, coughing and wheezing point to respiratory issues, and nausea with vomiting are GI symptoms; none describe vein-specific inflammation along the IV tract.
