Correct Answer is ["1"]

Explanation

To solve this problem, we first need to convert the client’s weight from pounds to kilograms. Then, we can calculate the total amount of amikacin needed. Finally, we can find out how many milliliters of amikacin injection the nurse should administer.

Convert the client’s weight to kilograms: Given that 1 kg = 2.2 lbs, we can calculate the client’s weight in kilograms as follows:

Weightinkg=WeightinlbsConversionfactor=110lbs2.2lbs/kg≈50kgWeightinkg=ConversionfactorWeightinlbs=2.2lbs/kg110lbs≈50kg

Calculate the total amount of amikacin needed: The doctor ordered 5 mg of amikacin per kg of body weight, so the total amount of amikacin needed is:

Totalamikacin=Doseperkg×Weightinkg=5mg/kg×50kg=250mgTotalamikacin=Doseperkg×Weightinkg=5mg/kg×50kg=250mg

Find out how many milliliters of amikacin injection the nurse should administer: Given that the available amikacin injection is 250 mg/mL, we can calculate the volume of injection needed as follows:

Volumeofinjection=TotalamikacinConcentrationofinjection=250mg250mg/mL=1mLVolumeofinjection=ConcentrationofinjectionTotalamikacin=250mg/mL250mg=1mL

So, the nurse should administer 1 mL of amikacin injection.

Correct Answer is ["1.2"]

Explanation

To calculate the dose of somatropin to be administered per dose, we first need to convert the child's weight from pounds to kilograms. We can do this using the following conversion factor:

1 kg = 2.2 lbs

Therefore, the child's weight in kilograms is:

weight_kg = 66 lbs / 2.2 lbs/kg = 30 kg

Next, we can calculate the total dose of somatropin to be administered per week using the following formula:

total_dose = weight_kg * 0.24 mg/kg/week

This gives us a total dose of:

total_dose = 30 kg * 0.24 mg/kg/week = 7.2 mg/week

Finally, we can calculate the dose of somatropin to be administered per dose by dividing the total dose by the number of daily doses:

dose_per_dose = total_dose / 6 doses/day = 1.2 mg/dose

Therefore, the nurse should administer 1.2 mg of somatropin per dose.

Answer: 1.2 mg of somatropin per dose.
