Robitussin DM contains 100 mg of guaifenesin per 1 teaspoon. How many milligrams of guaifenesin are in 10 mL?
200 mg
100 mg
75 mg
50 mg
The Correct Answer is A
Robitussin DM contains 100 mg of guaifenesin per 1 teaspoon. One teaspoon is equivalent to 5 milliliters, so 100 mg is present in 5 mL. Therefore, 10 mL of Robitussin DM contains 2 times the amount of guaifenesin in 1 teaspoon or 200 mg.

Correct Answer is B
Explanation
The correct answer is choice B. 31. To find the number of bottles required, use the formula: (dose x frequency x duration) / (bottle size x bottle concentration). In this case, (4 mg/kg x 43 kg x 3 times/day x 6 days) / (100 mg/bottle) = 30.96 bottles. Round up to the nearest whole number to get 31 bottles.
Correct Answer is A
Explanation
To calculate the time it will take to finish the infusion, we can use the formula:
Time = Volume / Rate
Plugging in the given values, we get:
Time = 1.5 L / 75 mL/hr Converting 1.5 L to mL, we get:
Time = 1500 mL / 75 mL/hr Simplifying, we get:
Time = 20 hours
Therefore, it will take 20 hours to finish the infusion at the current rate.
