A client is receiving a secondary IV infusion of potassium chloride (KCI) 30 mEq at a rate of 10 mEq an hour. The pharmacy dispenses a 100 mL of 0.9% normal saline (NS) containing KCI 30 mEq. 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 ["33"]
Rationale:
Given:
Total dose of Potassium Chloride: 30 mEq
Volume of solution: 100 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) = 30 mEq / 100 mL
Concentration (mEq/mL) = 0.3 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 / 0.3 mEq/mL
Infusion rate (mL/hr) = 33.33 mL/hr
Step 3: Round to the nearest whole number:
Infusion rate (mL/hr) ≈ 33 mL/hr

Correct Answer is ["30"]
Explanation
Given:
Total insulin in solution: 100 units
Volume of solution: 250 mL
Infusion rate: 12 units/hour
Step 1: Determine the concentration of insulin in the solution:
Concentration (units/mL) = Total insulin (units) / Volume of solution (mL)
Concentration (units/mL) = 100 units / 250 mL
Concentration (units/mL) = 0.4 units/mL
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Infusion rate (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 12 units/hr / 0.4 units/mL
Infusion rate (mL/hr) = 30 mL/hr
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
