Is the following statement about the Canadian health care sector True or False: Canada is among the top 10 worst polluters per capita

a) True
b) False

Choose the most appropriate selection below to finish this statement: Ophthalmology has a disproportionately high contribution to health care generated emissions when compared to other specialties because

a) Ophthalmology has among the highest patient volumes of all specialties
b) Ophthalmology has the highest procedural/surgical volumes of all specialties
c) Ophthalmology does not have a disproportionally high contribution to health care generated emissions when compared to other specialties

How many times higher than the annual energy consumption of an average commercial office building do health care facilities consume, making buildings and energy a critical area of focus for sustainable eye care?

a) 1.7x
b) 2x
c) 3x
d) Health care facilities do not consume higher than the energy consumption of an average commercial building. Sustainability efforts in eye care need not focus on energy and buildings.

a) Supply procurement of surgical materials
b) Supply procurement of non-surgical materials
c) Buildings and energy
d) OR waste

The greatest source of emissions from materials used for eye care derive from:

b) Downstream emissions (sorting, transportation, recycling, waste/disposal)

Which of the following statements is false:

a) Patients may be instructed to use topical multi-use eyedrops until the listed expiry date rather than replacing bottles after 1 month
b) To maintain optimal sterility, patients should not be given opened topical multi-use eyedrop bottles from the OR for use at home
c) Topical multi-use eyedrops from the same bottle may be used on multiple patients in the OR

Which one of the following statements regarding reduction of emissions associated with the OR in ophthalmology is false:

a) 23 km/case
b) 124 km/case
c) 197 km/case
d) 288 km/case
e) 336m km/case
