Question

A patient needs atropine 0.2 mg IM STAT. It's available in 0.4 mg/mL. What's the correct dosage for this patient?

A. 0.5 mL B. 0.1 mL C. 1 mL D. 5 mL

Answer 1

Answer:

The correct dosage is 0.5 ml

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

We can solve this question by using the simple Rule of Three property. The Property is the following

$\frac{a}{x} = \frac{b}{c}$ ⇒ $x = \frac{a*c}{b}$

Now we can use the property above using the values given to us to find the correct dosage for the patient.

$\frac{0.2mg}{x} = \frac{0.4mg}{1ml}$

$x = \frac{0.2mg*1ml}{0.4mg}$

$x = \frac{0.2ml}{0.4}$

$x = 0.5ml$

So Now we can see that the correct dosage is 0.5 ml
