Final answer:
Hypovolemic shock is characterized by low blood pressure, confusion, and thirst. The nurse should prioritize intravenous fluid resuscitation to restore blood volume and improve blood pressure, and treat the underlying cause of fluid loss.
Step-by-step explanation:
When a patient arrives in the emergency department with a blood pressure of 70/45, confusion, and thirst, it is indicative of a condition known as hypovolemic shock. Hypovolemic shock occurs when there is a significant loss of blood volume or fluids in the body.
The low blood pressure in this case is a result of decreased blood volume, leading to reduced perfusion to the organs and tissues. The confusion and thirst are signs of inadequate blood flow to the brain and the body's compensatory mechanism to encourage fluid intake respectively.
To address this situation, the nurse should prioritize intravenous fluid resuscitation to restore blood volume and improve blood pressure. In addition, the nurse should assess the patient for the source of fluid loss and treat any underlying causes. Close monitoring of vital signs, blood glucose levels, and urine output is essential in managing hypovolemic shock.
