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 A
Explanation
Answer: A. Budesonide 0.25 mg inhalation 2 times daily
Rationale:
A. Budesonide 0.25 mg inhalation 2 times daily:
While budesonide 0.25 mg is commonly prescribed for young children, a toddler weighing 30 kg exceeds the typical weight range for which this low dose is intended. Higher doses may be needed, and the dose should be clarified in relation to the child's size and clinical condition. The provider should confirm whether this is the appropriate dose.
B. Amoxicillin 250 mg PO q8h:
This is a commonly accepted pediatric dose for a toddler and generally falls within the safe dosage range for a child of 30 kg, especially when treating common infections. It does not require clarification.
C. Montelukast 4 mg PO daily:
Montelukast 4 mg is the standard daily dose for children aged 2–5 years. For a toddler (under 6), even if the weight is high, this dose is consistent with guidelines and doesn't require clarification.
D. Albuterol 2.5 mg inhalation q8h:
Albuterol 2.5 mg per nebulizer treatment is a standard dose for children, including toddlers, and can be safely administered every 6 to 8 hours. No clarification is needed for this order.
Correct Answer is ["2.1"]
Explanation
Step-by-step calculation:
The child's weight is 55 lb.
The medication dosage is 50,000 units/kg.
The available medication concentration is 600,000 units/mL.
Calculating the total dose in units:
Convert the child's weight to kg: 55 lb ÷ 2.2 lb/kg = 25 kg
Calculate the total dose: 25 kg × 50,000 units/kg = 1,250,000 units
Calculating the volume to administer:
Use the concentration of the medication: 1,250,000 units ÷ 600,000 units/mL = 2.0833 mL
Rounding the answer:2.0833 rounds to 2.1 mL
