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

Correct Answer is ["6"]
Explanation
Calculate the Total Infusion Time in Minutes:
The infusion is to be delivered over 4 hours.
There are 60 minutes in 1 hour.
Total infusion time: 4 hours x 60 minutes/hour = 240 minutes
Calculate the Drip Rate (gtt/min):
We'll use the following formula:
Drip Rate (gtt/min) = (Total Volume (mL) x Drop Factor (gtt/mL)) / Total Infusion Time (minutes)
Plug in the Values and Calculate:
Drip Rate (gtt/min) = (100 mL x 15 gtt/mL) / 240 minutes
Drip Rate (gtt/min) = 1500 gtt / 240 minutes
Drip Rate (gtt/min) = 6.25 gtt/min
Round to the Nearest Whole Number:
6 gtt/min
Correct Answer is ["30"]
Explanation
Understanding the Problem
Order: Potassium gluconate 40 mEq PO
Available Solution: Potassium gluconate liquid 20 mEq/15 mL
Desired Dose: mL to administer
Step 1: Set Up the Calculation
We need to find the volume (in mL) that contains the ordered dose (40 mEq). We can do this by setting up a proportion or using the formula:
Volume (mL) = (Ordered Dose (mEq) / Concentration (mEq/mL))
Step 2: Determine the Concentration
Available Concentration: 20 mEq / 15 mL
Step 3: Perform the Calculation
Ordered Dose: 40 mEq
Concentration: 20 mEq / 15 mL
Volume: (40 mEq) / (20 mEq / 15 mL) = (40 mEq X 15 mL) / 20 mEq
We can simplify this by dividing 40 by 20:
Volume: (2 X 15 mL) = 30 mL
Step 4: Round to the Nearest Whole Number
The result is 30 mL, which is already a whole number.
Answer: 30 mL
