Final answer:
The assessment finding that warrants immediate intervention by the nurse is mental stupor.
Step-by-step explanation:
The assessment finding that warrants immediate intervention by the nurse in this case is mental stupor.
Diabetic ketoacidosis (DKA) is a complication of diabetes where there is a build-up of ketones and acid in the blood. The patient in this scenario is demonstrating Kussmaul breathing (deep, rapid breathing) and has a severe headache along with nausea. A pH level of 7.50 indicates alkalosis, and the presence of fruity breath suggests the presence of acetone in the breath due to ketone production.
However, mental stupor is a concerning symptom that could indicate worsening dehydration and acidosis. It is a sign that the brain is not receiving enough glucose to function properly. Immediate intervention is necessary to address the underlying cause and prevent further complications.
