Image Based MCQ on Instruments

Hello awesomites!
Yesterday we posted an Image based MCQ on Instruments and here is the answer to the question.
Q. What is the inner diameter of the device shown in the picture if it is to be used in adults?

A. 2-3 mm
B. 8-9 mm
C. 12-15 mm
D. 21-23 mm
The correct answer is B. 8-9 mm. The image given shows an Endotracheal tube that is available in different sizes for different age groups.
Internal diameter 3mm - 6mm is used for Paediatric cases.
Typically, an 8.0 or 8.5 mm for adult men and 7.5 to 8.0 mm for adult women is an ideal choice.
Thanks for your active participation in the question.
