A primary healthcare provider prescribes 0.02 mg/kg tid glycopyrolate to a child with chronic severe drooling. A nurse finds that the child weighs 44 lb. Upon seeing the drug label, the nurse finds that 5 mL of medication contains 1 mg of drug.

What should the nurse do to provide safe medication to the child?

Administer 2 mL of medication to the child

Administer 1 tsp of medication to the child

Administer 0.8 mg of medication to the child

Administer 1 cup of medication to the child

Answer and Explanation

The Correct Answer is A

First, we need to convert the weight of the child from pounds to kilograms:. 44 lb / 2.2046 = 19.958 kg (rounded to three decimal places).

Next, we can calculate the dose of glycopyrrolate:. 0.02 mg/kg x 19.958 kg = 0.39916 mg.

We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 0.39916 mg seems reasonable for a child with chronic severe drooling..

Now, we need to determine how much medication to administer to the child. We know that 5 mL of medication contains 1 mg of drug. Therefore, to administer 0.39916 mg of glycopyrrolate, we need to administer:

(0.39916 mg / 1 mg) x 5 mL = 1.9958 mL.

We should round this dose to the nearest appropriate unit of measure. In this case, we can round to 2 mL to make it easier to measure and administer..

Therefore, the nurse should administer 2 mL of glycopyrrolate to the child three times a day (tid) to treat chronic severe drooling.

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.

A. 200 mg B. 100 mg C. 75 mg D. 50 mg

Correct Answer is A

Explanation

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.
