A patient with asthma is admitted with severe dyspnea and is unable to speak. The nurse finds that the patient looks drowsy and confused. Which other finding would the nurse expect?

A. Cerebral edema is the most dangerous complication associated with the administration of hypotonic fluids in patients with diabetic ketoacidosis (DKA). This occurs because hypotonic fluids cause rapid shifts in fluid and electrolytes, which can lead to swelling of the brain, especially in children. The risk is heightened if fluids are replaced too quickly.
B. Polyuria is a common symptom of diabetic ketoacidosis due to high blood glucose levels and osmotic diuresis, but it is not caused by hypotonic fluid administration.
C. Hypokalemia is a potential risk in DKA but typically arises from the shift of potassium from the extracellular to intracellular space during treatment, especially with insulin administration, not from the use of hypotonic fluids.
D. Metabolic acidosis is a hallmark of diabetic ketoacidosis itself and is caused by the accumulation of ketones. It is not caused by hypotonic fluid replacement.

A. Pheochromocytoma is a tumor of the adrenal glands that can cause excessive production of catecholamines (such as norepinephrine and epinephrine), leading to a hypertensive crisis. This condition can cause severe hypertension, headaches, palpitations, and sweating.
B. Adrenal insufficiency is typically associated with low blood pressure, not hypertension. It is characterized by symptoms like weakness, fatigue, and hypotension, which are not linked to hypertensive crises.
C. Hypothyroidism is associated with low blood pressure and bradycardia, not an increased risk of hypertensive crisis. It typically leads to symptoms like weight gain, fatigue, and cold intolerance.
D. Diabetes insipidus is a condition that leads to excessive urination and thirst due to a lack of antidiuretic hormone, but it does not directly lead to a hypertensive crisis. It is primarily concerned with electrolyte imbalance and dehydration.
