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

Correct Answer is ["105"]
Explanation
Given:
Ordered dose of Ceftazidime: 30 mg/kg/day
Infant's weight: 3,500 grams (3.5 kg)
Step 1: Calculate the total daily dose of Ceftazidime:
Total daily dose (mg) = Ordered dose (mg/kg/day) x Infant's weight (kg)
Total daily dose (mg) = 30 mg/kg/day x 3.5 kg
Total daily dose (mg) = 105 mg
Correct Answer is ["125"]
Explanation
Given:
Total dose of Potassium Chloride: 80 mEq
Volume of solution: 1 liter (1000 mL)
Infusion rate: 10 mEq/hour
Step 1: Determine the concentration of Potassium Chloride in the solution:
Concentration (mEq/mL) = Total Potassium Chloride (mEq) / Volume of solution (mL)
Concentration (mEq/mL) = 80 mEq / 1000 mL
Concentration (mEq/mL) = 0.08 mEq/mL
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Infusion rate (mEq/hr) / Concentration (mEq/mL)
Infusion rate (mL/hr) = 10 mEq/hr / 0.08 mEq/mL
Infusion rate (mL/hr) = 125 mL/hr
