The healthcare provider prescribes regular insulin 10 units/hour IV. The pharmacy provides a solution of normal saline 250 mL with 125 units regular insulin. How many hours should the IV infuse? (Enter numeric value only. if rounding is required, round to the nearest whole number.)
The Correct Answer is ["13"]
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

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
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
