## Question

A client with a peripheral doxorubicin extravasation received immediate infusion interruption, aspiration without flushing, intermittent cooling, elevation, and prescribed dexrazoxane. Creatinine clearance is 32 mL/min, so the antidote dose was reduced by 50%. Review the 3-day local, neurovascular, renal, and treatment trend. Select the best interpretation and ongoing plan.

| Time | Data |
| --- | --- |
| 1406 | Doxorubicin stopped; burning 7/10; erythema and swelling measure 3 cm by 4 cm; distal pulse and sensation intact |
| 1420 | Residual drug aspirated without flushing; catheter removed after aspiration; site photographed and protocol activated |
| 1500 | Creatinine clearance 32 mL/min; dexrazoxane dose reduced 50 percent; first infusion scheduled within 6 hours |
| Day 2 | Pain 3/10; erythema 2 cm by 2 cm; no blistering or ulceration; distal circulation and sensation remain intact |
| Day 3 | Pain 1/10; swelling minimal; no necrosis; third renal-adjusted dexrazoxane dose due |

Q1. How is the local injury responding?

Progressing rapidly to tissue necrosis despite treatment
Improving without current blistering, ulceration, or neurovascular compromise
Resolved completely at 1420 because blood return was present

Q2. Which ongoing plan is appropriate?

Stop dexrazoxane early because pain decreased
Restart doxorubicin through the affected extremity on Day 3
Complete the renal-adjusted 3-day course and continue local, blood-count, and renal monitoring
Massage the site daily to disperse remaining medication

## Explanation

The smaller erythema, lower pain, minimal swelling, intact distal neurovascular findings, and absence of blistering, ulceration, or necrosis show improvement. Complete the renal-adjusted 3-day dexrazoxane course and continue local, blood-count, and renal monitoring. Symptom improvement is not a reason to stop the antidote early; the affected extremity should not be reused for doxorubicin access, and massage may spread residual vesicant and worsen tissue injury.

## In-depth explanation

Quick answer
The local trend is improving, and the client needs completion of the renal-adjusted 3-day dexrazoxane course with continued surveillance.

Why this is correct
The Totect label uses 3 consecutive treatment days, begins within 6 hours, and requires a 50 percent dose reduction when creatinine clearance is below 40 mL/min. Decreasing pain and swelling without blistering support improvement but do not end follow-up.

Easy analogy or mental picture
A shrinking spill mark is progress, not permission to stop the cleanup early.

Memory hook
Better site plus complete antidote course plus continued monitoring.

NCLEX decision rule
Evaluate both the tissue response and whether time-sensitive therapy, renal adjustment, and follow-up remain correct.

Why the other choices are wrong
Stopping the antidote course early abandons the labeled regimen. Rechallenging the affected vein or assuming blood return proves recovery recreates risk.References

## Clinical scenario

Post-extravasation treatment trend
Improving pain and swelling do not replace completion of the renal-adjusted antidote course and continued tissue, blood-count, and kidney monitoring.
