Answer and Explanation

The Correct Answer is A

A. A patient who lost 2 liters of blood during surgery: This is the most acute and severe form of hypovolemia due to significant blood loss, requiring immediate fluid replacement and hemodynamic monitoring.

B. A patient who received 6 liters of IV fluid: This patient is at risk for hypervolemia, not hypovolemia, due to fluid overload.

C. A patient with UTI on PO meds: While dehydration may occur, it is typically mild and does not cause hypovolemia.

D. A patient with congestive heart failure: CHF usually leads to fluid retention, making hypovolemia unlikely unless there are other complicating factors.
