Do not use a trailing zero.). mL.
The Correct Answer is ["1.5 mL"]
Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 20 mg/mL. So, we calculate 30 mg ÷ 20 mg/mL = 1.5 mL. Rounded to the nearest tenth, this is 1.5 mL. So the correct answer is 1.5 mL.

Correct Answer is ["& mL"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in units/kg. There are approximately 2.2 lb/kg, so 130 lb ÷ 2.2 lb/kg = 59.1 kg. The doctor ordered calcitonin at a dosage of & units/kg, so we multiply the client’s weight in kg by the dosage: 59.1 kg × & units/kg = & units. The medication is available at a concentration of 200 units/mL, so we divide the total units needed by the units per mL: & units ÷ 200 units/mL = & mL.
So, the correct answer is & mL.
Correct Answer is ["83 mL\/hr"]
Explanation
Step 1 is to calculate the total volume to be infused. The total volume is 1 L, which is equal to 1000 mL. Step 2 is to divide the total volume by the total time. The total time is 12 hours. So, the calculation is 1000 mL ÷ 12 hr = 83.33 mL/hr.
So, the correct answer is 83 mL/hr, after rounding to the nearest whole number.
