What should a PACU nurse do first if a patient exhibits signs of hypotension?

In a scenario where a patient exhibits signs of hypotension, the most critical initial action for a PACU nurse is to assess the patient's fluid status. Evaluating fluid status involves checking for signs of hypovolemia, such as decreased urine output, dry mucous membranes, and checking peripheral perfusion. Understanding the patient's volume status allows the nurse to determine if the hypotension could be due to inadequate fluid levels or other factors.

After assessing fluid status, appropriate interventions can be initiated, which may include administering IV fluids if the individual is dehydrated or adjusting medications. This thorough assessment is vital before escalating the situation by calling a physician, performing CPR, or adjusting oxygen supply, as those actions depend heavily on understanding the underlying cause of the hypotension. Without addressing the fluid status first, other measures may not be effective or appropriate based on the patient's condition.
