Answer:

c) "I'll avoid eating or drinking anything 6 to 8 hours before the test."

Explanation:

  • Barium is a white substance like chalk. For swallowing, it mixed with water and its thick like milk-shake.
  • When it enters into GI tract, it coated with tract lining so when we do X-ray it shows white on X-ray film because barium absorb the X-ray.
  • It should be advised the patient to avoid the eating and drinking for clear picture of X-ray film otherwise food debries etc will affect the diagnosis and interpretation of results.
