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.

Correct Answer is ["400"]
Explanation
Step by step calculation:
The nurse needs to administer 100 mL of sodium chloride.
The infusion time is 15 minutes.
Calculating the flow rate in mL/hr:
Convert the infusion time to hours: 15 minutes ÷ 60 minutes/hour = 0.25 hours
Divide the total volume by the infusion time: 100 mL ÷ 0.25 hours = 400 mL/hour
Correct Answer is ["3.9"]
Explanation
Let's break down the calculation step by step:
Understanding the information:
The child's weight is 26 lb.
The medication dosage is 2 mg/kg/day.
The available medication concentration is 15 mg/5 mL.
The medication is to be divided into two equal doses per day.
Calculating the total dose per day in mg:
Convert the child's weight to kg:
26 lb ÷ 2.2 lb/kg = 11.82 kg
Calculate the total dose per day:
11.82 kg × 2 mg/kg/day = 23.64 mg/day
Calculating the dose per dose:
Divide total dose by 2: 23.64 mg/day ÷ 2 doses/day = 11.82 mg/dose
Calculating the volume to administer per dose:
Use the concentration of the medication: 11.82 mg ÷ (15 mg/5 mL) = 11.82 mg ÷ 3 mg/mL = 3.94 mL
Rounding the answer:
3.94 rounds to 3.9 mL
