Question

During surgical repair of a detached retina, 1 mL of sulfur hexafluoride is injected into the posterior chamber. If the patient is receiving 4 mL of sulfur hexafluoride, the volume injected will ________.

1) decrease by one third
2) remain the same
3) double
4) triple

Answer 1

The volume of sulfur hexafluoride injected during the surgery triples when increased from 1 mL to 4 mL.

Step-by-step explanation:

When considering the volume of sulfur hexafluoride injected into the posterior chamber during a surgical repair of a detached retina, if the initial volume is 1 mL and the patient is receiving 4 mL, the volume injected will triple. This is because the increase from 1 mL to 4 mL represents three additional milliliters on top of the original one milliliter, resulting in a total volume that is four times the original, which means the increase is threefold.
