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 ["1.3"]
Explanation
Given:
Ordered dose of Filgrastim: 5 mcg/kg/daily
Patient weight: 176 pounds
Concentration of Filgrastim: 300 mcg/mL
Step 1: Convert patient weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Patient weight in kg = 176 lbs x 0.453592 kg/lb = 79.832 kg
Step 2: Calculate the total daily dose of Filgrastim:
Total daily dose (mcg) = Ordered dose (mcg/kg/daily) x Patient weight (kg)
Total daily dose (mcg) = 5 mcg/kg/daily x 79.832 kg
Total daily dose (mcg) = 399.16 mcg
Step 3: Calculate the volume to be administered:
Volume (mL) = Total daily dose (mcg) / Concentration (mcg/mL)
Volume (mL) = 399.16 mcg / 300 mcg/mL
Volume (mL) = 1.3305 mL
Step 4: Round to the nearest tenth:
Volume (mL) ≈ 1.3 mL
Correct Answer is ["4"]
Explanation
Given:
Ordered dose of amoxicillin/clavulanate: 2 g amoxicillin + 125 mg clavulanate every 12 hours
Available tablets: 1000 mg amoxicillin + 62.5 mg clavulanate extended-release tablets
Step 1: Determine the total daily dose of amoxicillin/clavulanate:
Since the medication is given every 12 hours, there are 2 administrations per day.
Total daily dose (amoxicillin) = Dose per administration (amoxicillin) x Number of administrations per day
Total daily dose (amoxicillin) = 2 g/dose x 2 doses/day
Total daily dose (amoxicillin) = 4 g/day = 4000 mg/day
Total daily dose (clavulanate) = Dose per administration (clavulanate) x Number of administrations per day
Total daily dose (clavulanate) = 125 mg/dose x 2 doses/day
Total daily dose (clavulanate) = 250 mg/day
Step 2: Calculate the number of tablets required per day:
Number of tablets/day = Total daily dose (amoxicillin) / Strength of amoxicillin per tablet
Number of tablets/day = 4000 mg/day / 1000 mg/tablet
Number of tablets/day = 4 tablets/day
