When the dental chair is returned to upright, the patient feels dizzy and light-headed. Most likely cause?
Show answer and explanation
Correct answer: A. Orthostatic (postural) hypotension
- A. Correct. Dizziness on rapid position change from supine to upright is classic orthostatic hypotension (transient drop in BP).
- B. Vasovagal syncope is typically triggered by fear/pain/sight of needles, often with pallor/nausea, not simply chair repositioning.
- C. Hypoglycemia causes tremor/sweating/confusion, not position-dependent dizziness.
- D. MI presents with chest pain/radiation, not isolated positional light-headedness.
