If a patient has dry chemical fertilizer on their arms, what is the best management approach?

For a patient with dry chemical fertilizer on their arms, the best management approach involves brushing away the chemical powder and then flushing the area with running water. This method is effective because it first removes the bulk of the chemical substance that could continue to cause irritation or injury. By brushing off as much of the chemical as possible, you reduce its contact with the skin.

Flushing with running water is crucial as it helps to dilute and wash away any remaining chemical particles. This action minimizes the risk of further skin damage and alleviates the potential for chemical burns or irritation. It’s essential to use water as soon as possible after exposure, and the treatment should be prolonged if there are ongoing signs of irritation.

The other options do not effectively address the immediate need to remove the chemical and prevent harm. Handing the patient over to a dermatologist without initial decontamination would not provide urgent care. Applying a wet dressing could trap chemicals against the skin, causing more damage. Covering the area with a bandage is also inappropriate initially, as it does not address the immediate decontamination needed to protect the skin from the chemical’s effects.
