When repositioning a dental chair to the upright position, the patient suddenly feels dizzy and lightheaded. What is the most appropriate IMMEDIATE action?

  1. Return the chair to the supine (tilted back) position
  2. Call emergency services (911)
  3. Administer oxygen
  4. Administer nitroglycerin sublingual
Show answer and explanation

Correct answer: A. Return the chair to the supine (tilted back) position

Dizziness/lightheadedness when moving to upright = orthostatic hypotension (blood pools in lower extremities). IMMEDIATE treatment: return to SUPINE position — redistributes blood, restores venous return and cerebral perfusion. Source confirms: 'Supine position.'
  • A. CORRECT. Return to supine position — redistributes blood, restores BP and cerebral perfusion. First treatment for orthostatic hypotension.
  • B. 911 if patient loses consciousness or doesn't recover — first step is positional management.
  • C. Oxygen may be given after positioning but is NOT the primary immediate action.
  • D. Nitroglycerin would LOWER blood pressure and WORSEN the hypotension — absolutely contraindicated.
