Question

Quizplus · Accepted Answer

To find out how many mL is needed, we can set up a proportion:
8 mg/1 mL = 14 mg/x mL
Cross-multiplying, we get:
8x = 14
x = 14/8
x = 1.75
Therefore, we need to administer 1.75 mL. To administer 14 mg with a solution strength of 8 mg/mL, we need to use the formula:

Amount of medicine = Solution strength x Volume of solution

Let x be the volume of solution we need to administer. Then:

14 mg = 8 mg/mL x x

x = 1.75 mL

Therefore, the answer is D.
