Correct Answer is C
Explanation
To calculate the drug dosage, multiply the prescribed dose per kilogram by the client’s weight in kilograms:
0.5 mg/kg x 57 kg = 28.5 mg
Correct Answer is A
Explanation
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.
