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 C

Explanation

To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..

So the nurse should add 250 mL of water to the formula to dilute it to half strength.

A. 21.6 mL B. 26.4 mL C. 54 mL D. 64.8 mL

Correct Answer is A

Explanation

To calculate the dose of brentuximab in mg that the client should receive, we need to multiply the weight of the client in kg by the prescribed dose of 1.8 mg/kg:.

Dose (in mg) = Weight (in kg) x Dose (in mg/kg).

Dose (in mg) = 60 kg x 1.8 mg/kg. Dose (in mg) = 108 mg.

Now we need to calculate the volume of medication to administer. Since the medication available is 50 mg per 10 mL, we can use proportion to calculate the volume:.

50 mg is to 10 mL as 108 mg is to X mL. 50/10 = 108/X.

Cross-multiplying, we get:. 50X = 108 x 10.

X = (108 x 10)/50. X = 21.6 mL.

Therefore, the nurse should administer 21.6 mL of brentuximab to the client.
