A child with an infection receives prescription for cefixime 80 mg by mouth every 12 hours. The bottle is labeled, Cetixime for Oral Suspension, USP 100 mg 5 mL. How many mL should nurse administer? (Enter numerical value only.)
The Correct Answer is ["4"]
Given:
Ordered dose of Cefixime: 80 mg
Concentration of Cefixime suspension: 100 mg per 5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
80 mg / Volume = 100 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 80 mg / (100 mg/5 mL)
Volume = 80 mg x (5 mL / 100 mg)
Volume = 4 mL

Explanation
Given:
Ordered dose of Dexamethasone: 0.6 mg/kg
Child's weight: 35 pounds
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 35 lbs x 0.453592 kg/lb = 15.87572 kg
Step 2: Calculate the total dose of Dexamethasone:
Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)
Total dose (mg) = 0.6 mg/kg x 15.87572 kg
Total dose (mg) = 9.525432 mg
Step 3: Round to the nearest whole number:
Total dose (mg) ≈ 10 mg
Correct Answer is ["13"]
Explanation
Given:
Total insulin in solution: 125 units
Ordered infusion rate: 10 units/hour
Step 1: Calculate the total infusion time:
Total infusion time (hours) = Total insulin (units) / Infusion rate (units/hour)
Total infusion time (hours) = 125 units / 10 units/hour
Total infusion time (hours) = 12.5 hours
Step 2: Round to the nearest whole number:
Total infusion time (hours) ≈ 13 hours
