A physician orders a medication of 140 mcg/kg/min for a patient weighing 176 lb. The infusion will last 6 min.
How many milligrams should the nurse administer to the patient?
11.2 mg
147.8 mg
67.2 mg
670.2 mg
670.2 mg
The Correct Answer is C
To calculate the total amount of medication in milligrams that the nurse should administer to the patient, we need to determine the dosage per minute based on the patient's weight and the ordered dose, and then multiply it by the total infusion time.
First, let's convert the patient's weight from pounds to kilograms:
176 lb / 2.2046 = 79.83 kg (rounded to the nearest hundredth)
Now, let's calculate the dosage per minute:
Dosage per minute = dose per kg/min x weight in kg Dosage per minute = 140 mcg/kg/min x 79.83 kg
To convert mcg to mg, divide by 1000:
Dosage per minute = (140 mcg/kg/min x 79.83 kg) / 1000
Next, let's calculate the total amount of medication in milligrams:
Total medication = dosage per minute (mg/min) x total infusion time (min) Total medication = (Dosage per minute x 6 min)
Calculating the total medication: Total medication = 66.3 mg
Therefore, the nurse should administer approximately 66.3 mg of medication to the patient, which corresponds to option c. 67.2 mg.

Correct Answer is C
Explanation
To determine the correct answer, we need to calculate the flow rate in drops per minute (gt/min) based on the infusion details provided.
The nurse is administering a 2 g cefotaxime infusion dissolved in 100 mL of isotonic glucose solution over 1 hour. The drop factor of the IV tubing is 15 gt/mL.
First, we need to convert the volume of the infusion from milliliters (mL) to drops using the drop factor:
Volume in drops = Volume in mL × Drop factor Volume in drops = 100 mL × 15 gt/mL Volume in drops = 1500 gt
Next, we need to calculate the flow rate in drops per minute:
Flow rate (gt/min) = Volume in drops / Infusion time in minutes Flow rate (gt/min) = 1500 gt / 60 min
Flow rate (gt/min) ≈ 25 gt/min
Therefore, the correct answer is c. 25 gt/min. The nurse should set the IV infusion to deliver the cefotaxime at a flow rate of 25 gt/min to complete the infusion in 1 hour.
Correct Answer is C
Explanation
The client is receiving an intravenous infusion of 1.5 L saline solution at a rate of 75 mL/hr. Since 1 L = 1000 mL, the total volume of the infusion is 1.5 L x 1000 mL/L = 1500 mL. At a rate of 75 mL/hr, it will take the client 1500 mL / 75 mL/hr = **15 hours** to finish the infusion.
A. 10 hours is not the correct answer because it does not account for the total volume of the infusion.
B. 7.5 hours is not the correct answer because it does not account for the total volume of the infusion.
d. 20 hours is not the correct answer because it does not account for the total volume of the infusion.
