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
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 D
Explanation
First, we need to calculate the total dose of esmolol required per minute: Total dose = Weight x Dose x 60 minutes
Total dose = 65 kg x 200 mcg/kg/min x 60 minutes Total dose = 780,000 mcg/min
Next, we need to convert the dose to milligrams (mg):
780,000 mcg/min = 780 mg/min
The concentration of the esmolol solution is 2,500 mg in 250 mL or 10 mg/mL. To deliver 780 mg/min at a concentration of 10 mg/mL, we need to infuse: Infusion rate = Total dose / Concentration
Infusion rate = 780 mg/min / 10 mg/mL Infusion rate = 78 mL/min
Rounding to the nearest whole number, the answer is D. 78 mL/hr.
Therefore, the nurse should calculate an infusion rate of 78 mL/hr to deliver the required dose of esmolol to the patient.
Correct Answer is C
Explanation
The patient is ordered to receive 0.15 mg/kg of Zofran over 15 minutes. The patient weighs 176 lb, which is equivalent to 80 kg. To calculate the total amount of Zofran the patient should receive, multiply the weight by the dosage:
80 kg x 0.15 mg/kg = 12 mg
The Zofran arrives from the pharmacy mixed in 50 mL of normal saline, which means there is 12 mg of Zofran in 50 mL of solution. To calculate how many milliliters per hour the nurse should set the IV pump, we can use the following formula:
50 mL / 0.25 hour = X mL per hour X = 200 mL per hour
Therefore, the nurse should set the IV pump to deliver 200 mL of Zofran per hour to the patient.
