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 ["650"]
Step by step calculation:
Plug in the values:
1 tablet contains 650 mg of calcium carbonate.
Perform the calculations:
1 tablet / 650 mg = 1 tablet / x mg
Solve for x:
Cross-multiply: 650 mg x 1 tablet = 1 tablet x x mg
Rounding and final answer:
x = 650 mg.

Correct Answer is ["2.7"]
Explanation
Step 1: Convert the child's weight from pounds to kilograms.
We know that 1 kg = 2.2 lb,
Weight in kg=Weight in lb=78/2.2≈35.45 kg
Step 2: Calculate the required dose of ondansetron in mg.
The prescribed dose is 0.15 mg per kg:
Dose in mg=0.15 mg/kg×35.45 kg=5.318 mg
Step 3: Determine the volume of ondansetron to administer.
To determine how many mL the nurse should administer, we use the following formula:
Volume (mL)=Dose in mg/Concentration in mg/mL=5.318 mg/2 mg/mL=2.659 mL
Step 4: Round the answer:
Rounding 2.659 mL gives 2.7 mL.
