Answer:
0.6mL
Explanation:
In general you can find the actual volume to be administered as follows:
actual volume = (actual amount / dose amount) x dose volume
actual volume = (175mcg / 300mcg) x 1mL = 0.58mL
In practice it would probably be easier to just administer 0.6mL. The difference in dose won't be clinically meaningful.
