Final answer:
The nurse should clarify the prescription of Glipizide for a client diagnosed with diabetic ketoacidosis, as it is not typically used in the acute management of this condition, unlike insulin and potassium which are standard treatments, and 0.9% sodium chloride used for rehydration.
Step-by-step explanation:
The nurse will clarify the prescription of Glipizide with the healthcare provider when reviewing medications for a client diagnosed with diabetic ketoacidosis (DKA). Regular insulin is a standard treatment for DKA because it helps to reduce blood glucose levels by facilitating the uptake of glucose into cells. Potassium may be required because insulin administration can cause hypokalemia, where potassium moves into cells alongside glucose, potentially leading to a dangerous reduction in blood potassium levels.
The infusion of 0.9% sodium chloride is common practice for rehydration during DKA treatment. However, Glipizide, an oral hypoglycemic, is not used in the acute management of DKA and could potentially worsen the patient's condition by further stimulating endogenous insulin secretion when exogenous insulin administration is already part of the treatment protocol.
