A nurse is reviewing instructions with an adolescent client who is to take calcium carbonate 1,300 mg PO daily. After reviewing the medication label below, the nurse should instruct the client that one tablet contains how many mg of calcium carbonate? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["350"]
Step by step calculation:
Plug in the values:
1 tablet contains 350 mg of calcium carbonate.
Perform the calculations:
1 tablet / 350 mg = 1 tablet / x mg
Solve for x:
Cross-multiply: 350 mg x 1 tablet = 1 tablet x x mg
Rounding and final answer:
x = 350 mg.

Identify the formula for volume to administer:
Volume (mL)=Dose ordered (mg)/Available concentration (mg/mL)
Substitute the given values:
Dose ordered = 25 mg
Available concentration = 37.5 mg/mL
Volume=25/37.5=0.6667mL.
Round to the nearest hundredth:
0.6667=0.67mL.
Correct Answer is ["3.5"]
Explanation
Convert the child’s weight from pounds to kilograms:
52 lb÷2.2=23.6 kg.
Calculate the total daily dose in micrograms (mcg):
7.5 mcg/kg/day×23.6 kg=177 mcg/day.
Determine the volume in mL to administer:
The elixir concentration is 50 mcg/mL
177 mcg÷50 mcg/mL=3.54 mL.
Round to the nearest tenth:
3.54 rounds to 3.5 mL.
