Question 2 of 5
Describe the first intervention you should perform when a patient faints because of low blood pressure.
Correct Answer: A
Rationale: Laying the patient flat and elevating their legs increases venous return to the heart, improving blood pressure and cerebral perfusion in cases of fainting due to hypotension.
