An adult client experiencing pain associated with maxillofacial surgery receives a prescription for acetaminophen and codeine phosphate oral solution 25 mL PO every 6 hours PRN. The bottle is labeled: "Acetaminophen and Codeine Phosphate Oral Solution, USP: 120/12 mg per 5 mL." How many mg of codeine will the client receive with each dose? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["60"]
Given:
Ordered dose: 25 mL PO every 6 hours PRN
Medication label: "Acetaminophen and Codeine Phosphate Oral Solution, USP: 120/12 mg per 5 mL"
Step 1: Determine the concentration of codeine in the solution:
Concentration of Codeine = Amount of Codeine / Volume of Solution
Concentration of Codeine = 12 mg / 5 mL
Concentration of Codeine = 2.4 mg/mL
Step 2: Calculate the amount of codeine per dose:
Amount of Codeine per Dose = Concentration of Codeine x Volume per Dose
Amount of Codeine per Dose = 2.4 mg/mL x 25 mL
Amount of Codeine per Dose = 60 mg

Vial strength: Cefotaxime 2 grams (2000 mg)
Volume of diluent: 50 mL of normal saline
Step 1: Calculate the concentration of Cefotaxime in the reconstituted solution:
Concentration (mg/mL) = Total amount of Cefotaxime (mg) / Total volume of solution (mL)
Concentration (mg/mL) = 2000 mg / 50 mL
Concentration (mg/mL) = 40 mg/mL
Correct Answer is ["1"]
Explanation
Given:
Ordered dose of loratadine: 5 mg
Concentration of loratadine suspension: 5 mg per 5 mL
1 teaspoon = 5 mL
Step 1: Determine the volume of loratadine suspension to be administered:
Since the ordered dose and the concentration are the same (5 mg), the volume to be administered is 5 mL.
Step 2: Convert mL to teaspoons:
1 teaspoon = 5 mL
Volume in teaspoons = 5 mL / 5 mL/teaspoon
Volume in teaspoons = 1 teaspoon
