Final answer:
The patient with Type 2 DM showing symptoms of dizziness, paleness, and diaphoresis with a low BP may require IV fluids to manage potential hypovolemic shock and IV dextrose for hypoglycemia, after confirmation with rapid bedside glucose testing.
Step-by-step explanation:
A Type 2 diabetes mellitus (DM) patient who is feeling dizzy, pale, diaphoretic, with low blood pressure (BP 80/60), is currently receiving oxygen via nasal cannula (O2 4L/min) and has an intravenous (IV) line in place. The symptoms described suggest the patient may be experiencing a hypoglycemic event, a condition where blood glucose levels drop too low. The immediate treatment for this condition usually involves administering a fast-acting carbohydrate.
However, since the BP is significantly low, indicating potential hypovolemic shock which could be due to severe dehydration or other causes, it is critical to stabilize the patient's blood pressure. In an emergency setting, intravenous (IV) fluids, such as normal saline or lactated Ringer's solution, are often administered to increase blood volume and improve BP. If hypoglycemia is confirmed through rapid bedside glucose testing, IV dextrose would also be required. Moreover, close monitoring of glucose levels and vital signs, along with further evaluation, will be necessary.
