A client with a renal calculi receives a prescription for an IV infusion of 0.9% sodium chloride 1,000 ml to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["400"]
Given:
Volume of fluid: 1000 mL
Infusion time: 2.5 hours
Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)
Step 1: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = 1000 mL / 2.5 hr
Flow rate (mL/hr) = 400 mL/hr

Correct Answer is ["40"]
Explanation
Given:
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 ["0.2"]
Explanation
Given:
Ordered dose of Atropine Sulfate: 0.01 mg/kg
Child's weight: 44 pounds
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 44 lbs x 0.453592 kg/lb = 19.958 kg
Step 2: Calculate the total dose of Atropine Sulfate:
Total dose (mg) = Ordered dose (mg/kg) x Child's weight (kg)
Total dose (mg) = 0.01 mg/kg x 19.958 kg
Total dose (mg) = 0.19958 mg
Step 3: Round to the nearest tenth:
Total dose (mg) ≈ 0.2 mg
