A nurse is preparing to administer eptifibatide 0.18 mg/kg IV bolus to a client who weighs 212 lb. Available is eptifibatide 20 mg/10 ml - How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8.7"]
Convert the Client's Weight from Pounds to Kilograms:
1 kg = 2.205 lbs
Weight in kg = 212 lbs / 2.205 lbs/kg
Weight in kg ≈ 96.145 kg
Calculate the Total Dose of Eptifibatide Needed:
Dose = 0.18 mg/kg x 96.145 kg
Dose ≈ 17.306 mg
Calculate the Volume of Eptifibatide to Administer:
Available concentration = 20 mg/10 mL
To simplify, we can find the concentration per 1 mL: 20 mg / 10 mL = 2 mg/mL
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
Volume (mL) = 17.306 mg / 2 mg/mL
Volume (mL) ≈ 8.653 mL
Round to the Nearest Tenth:
8.7 mL

Explanation
Understanding the Problem
Order: Esmolol 45 mcg/kg/min
Client Weight: 52 kg
Available Solution: Esmolol 2,500 mg in 250 mL of D5W
Desired Rate: mL/hr
Step 1: Calculate the Total Dose per Minute
Dose: 45 mcg/kg/min
Client Weight: 52 kg
Total Dose: 45 mcg/kg/min x 52 kg = 2340 mcg/min
Step 2: Convert Micrograms (mcg) to Milligrams (mg)
1 mg = 1000 mcg
Dose in mg/min: 2340 mcg/min / 1000 mcg/mg = 2.34 mg/min
Step 3: Calculate the Dose per Hour
Dose in mg/min: 2.34 mg/min
Minutes in an Hour: 60 min
Dose in mg/hr: 2.34 mg/min x 60 min/hr = 140.4 mg/hr
Step 4: Determine the Concentration of the Esmolol Solution
Available Esmolol: 2,500 mg
Solution Volume: 250 mL
Concentration: 2,500 mg / 250 mL = 10 mg/mL
Step 5: Calculate the Infusion Rate in mL/hr
Dose in mg/hr: 140.4 mg/hr
Concentration: 10 mg/mL
Infusion Rate: 140.4 mg/hr / 10 mg/mL = 14.04 mL/hr
Step 6: Round to the Nearest Whole Number
The calculated rate is 14.04 mL/hr.
Rounded to the nearest whole number: 14 mL/hr
Answer: 14 mL/hr
Correct Answer is ["38"]
Explanation
Identify the Given Information:
Infusion Rate: 150 mL/hr
Drop Factor: 15 gtt/mL
Convert the Infusion Rate to mL/min:
There are 60 minutes in 1 hour.
Infusion Rate (mL/min) = 150 mL/hr / 60 min/hr
Infusion Rate (mL/min) = 2.5 mL/min
Calculate the Drip Rate (gtt/min):
Drip Rate (gtt/min) = Infusion Rate (mL/min) x Drop Factor (gtt/mL)
Drip Rate (gtt/min) = 2.5 mL/min x 15 gtt/mL
Drip Rate (gtt/min) = 37.5 gtt/min
Round to the Nearest Whole Number:
38 gtt/min
