Final answer:
In DKA, decreased skin turgor and dry mucous membranes are due to dehydration caused by excessive water loss.
Step-by-step explanation:
In diabetic ketoacidosis (DKA), decreased skin turgor and dry mucous membranes are due to dehydration caused by excessive water loss.
In DKA, the body does not have enough insulin to use glucose for energy, so it starts breaking down fat for fuel. This produces ketones, which can cause the blood to become acidic. The excessive urination and sweat associated with DKA can lead to dehydration and the resulting symptoms of decreased skin turgor and dry mucous membranes.
It is important to treat DKA promptly to rehydrate the body and restore electrolyte balance.
