Final answer:
When a patient feels dizzy and might faint, placing them in a supine position on their back can help prevent fainting and aid in recovery, especially in cases such as Orthostatic Hypotension.
Step-by-step explanation:
If a patient tells you that he/she is feeling dizzy and might faint, the ideal position to place them in would be supine. This position involves lying the patient on their back, face-up. By positioning the patient supine, you help in stabilizing their blood pressure and facilitate easier breathing, which can prevent fainting and aid in recovery. When a person is dizzy or lightheaded due to conditions like Orthostatic Hypotension, a supine position can help mitigate the effects of gravity on blood flow to the brain.
