A client with cancer is receiving chemotherapy with a known vesicant. The client's IV has been in place for 72 hours. The nurse determines that a new IV site cannot be obtained, and leaves the present IV in place. Which is the greatest clinical risk related to this situation?

A. Anaphylactic. Anaphylactic reactions are caused by severe allergic responses, leading to histamine release, vasodilation, and bronchoconstriction. While burns trigger an immune response, it is an inflammatory reaction rather than an allergic one.
B. Noncompensatory. The body's response to burns is compensatory, not noncompensatory. The body immediately reacts by activating the inflammatory and stress responses to maintain perfusion and initiate healing.
C. Inflammatory. A severe burn triggers an immediate and massive inflammatory response, causing capillary leakage, fluid shifts (burn shock), and immune activation. This leads to edema, hypovolemia, and increased risk of infection. The inflammatory response also activates cytokines and white blood cells to begin tissue repair.
D. Cholinergic. The cholinergic response is related to the parasympathetic nervous system, which controls rest-and-digest functions. Severe burns primarily activate the sympathetic nervous system (fight-or-flight), leading to vasoconstriction, tachycardia, and increased metabolic demands.

A. Serum blood glucose 185 mg/dL (10.2 mmol/L) (Incorrect): Although lower than the previous reading, it is still elevated, which can impair healing and increase the risk of infection recurrence.
B. Temperature 98.8°F (37.1°C) (Therapeutic Response): A return to a normal temperature indicates resolution of systemic infection. Fever is a sign of active infection, so its absence suggests improvement.
C. White blood cell count 11.2 x 10³/μL (11.2 x 10⁹/L) (Incorrect): This is slightly elevated, which may indicate residual inflammation or infection. A further decrease would be expected for full resolution.
D. Capillary refill greater than 3 seconds bilateral lower extremities (Incorrect): Delayed capillary refill suggests impaired circulation, which is not an indicator of a fully therapeutic response.
E. Bilateral lower extremities skin warm, dry, and pink (Therapeutic Response): Improved skin condition suggests reduced inflammation, better circulation, and healing of the cellulitis-affected area.
F. Pain 2 on a 0 to 10 pain scale, bilateral lower legs described as neuropathic (Therapeutic Response): Pain related to cellulitis typically improves with treatment. If the remaining pain is neuropathic, it suggests resolution of the acute infection.
