Final answer:
Administering intravenous fluids is the next step in management for a diabetic patient presenting with symptoms of hypovolemic shock.
Step-by-step explanation:
The next step in management for a diabetic patient presenting with dizziness, pale skin, diaphoresis, bradycardia, and a blood pressure of 80/60 is to administer intravenous fluids.
Hypovolemic shock, caused by fluid losses related to severe vomiting or diarrhea, can lead to the symptoms described. Fluid resuscitation is the first-line treatment for hypovolemic shock, aiming to restore the patient's blood volume and improve blood pressure and perfusion.
