A client with dehydration is prescribed a potassium chloride infusion at 10 mEq/hr. Potassium chloride 80 mEq is mixed with 1 liter of normal saline. The nurse should regulate 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 ["125"]
To calculate the infusion rate in mL/hour, we'll use the following formula:
Infusion Rate (mL/hr) = Desired Dose (mEq/hr) / Concentration of Potassium Chloride (mEq/mL)
1. Calculate the concentration of potassium chloride:
Concentration = 80 mEq / 1000 mL = 0.08 mEq/mL
2. Plug in the values:
Infusion Rate (mL/hr) = 10 mEq/hr / 0.08 mEq/mL
3. Calculate:
Infusion Rate (mL/hr) = 125 mL/hr
Therefore, the nurse should regulate the infusion pump to deliver 125 mL/hour.

Correct Answer is ["2.5"]
Explanation
The client weighs 172 pounds which is equivalent to 78.02 kg (1 kg = 2.20462 pounds).
The prescription for levothyroxine is 1.6 mcg/kg/day, so the client should receive 124.83 mcg of levothyroxine per day (1.6 mcg/kg/day * 78.02 kg).
The medication is available in 50 mcg scored tablets, so the nurse should administer 2.5 tablets per day (124.83 mcg / 50 mcg/tablet).
Correct Answer is ["56"]
Explanation
Answer: 56 gtt/min.
Rationale:
To calculate the infusion rate in gtt/min, we'll use the following formula:
Infusion Rate (gtt/min) = Volume (mL) / Time (min) x Drop Factor (gtt/mL)
1. Convert volume to mL:
2 liters = 2000 mL
2. Convert time to minutes:
12 hours = 12 x 60 = 720 minutes
3. Plug in the values:
Infusion Rate (gtt/min) = 2000 mL / 720 min x 20 gtt/mL
4. Calculate:
Infusion Rate (gtt/min) ≈ 55.56 gtt/min
5. Round to the nearest whole number:
Infusion Rate (gtt/min) ≈ 56 gtt/min
Therefore, the nurse should regulate the infusion to 56 gtt/min.
