Rationale: In severe Aspirin toxicity, respiratory depression can occur due to increasing respiratory acidosis. Aspirin toxicity leads to metabolic acidosis, stimulating the respiratory center in the brain to increase the respiratory rate initially. However, as the toxicity worsens, respiratory muscle fatigue and depression can occur, resulting in respiratory depression. This can lead to hypoxia, respiratory failure, and ultimately, respiratory arrest.

Correct Answer: D

Rationale: Avoiding reinserting the needle into an IV catheter is crucial to minimizing the risk of catheter embolism. Reinserting the needle can lead to the severing of the catheter's end, potentially causing a catheter embolism, a serious complication.
