Final answer:
One of the most important interventions to reduce the effect of diarrhea on Alexander's skin is 1) applying a moisturizer.
Step-by-step explanation:
This is because diarrhea can lead to excessive loss of fluids and electrolytes from the body, which can result in dehydration. Dehydration can cause dry and irritated skin. By applying a moisturizer, Alexander can help replenish the lost moisture and prevent his skin from becoming dry and compromised.
Additionally, wearing loose-fitting clothing can also be helpful in reducing the effect of diarrhea on the skin. Loose-fitting clothing allows for better air circulation and can prevent friction and irritation on the skin. This can help alleviate any discomfort caused by the diarrhea.
Using a mild soap is another important intervention to reduce the effect of diarrhea on Alexander's skin. Harsh soaps can further strip the skin of its natural oils and disrupt the skin barrier. A mild soap, on the other hand, is less likely to cause further irritation and can help maintain the natural moisture balance of the skin.
Avoiding hot showers is important because hot water can strip the skin of its natural oils and dry it out. This can worsen the dryness and irritation caused by diarrhea. Therefore the correct answer is 1) applying a moisturizer.
