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 ["1.9"]
Explanation
Order: Dexamethasone 0.5 mg/kg/day IM, divided equally every 6 hours
Client Weight: 132 lbs
Available Solution: Dexamethasone 4 mg/mL
Desired Dose: mL per dose
Step 1: Convert Client Weight to Kilograms (kg)
1 kg = 2.2 lbs
Client Weight in kg: 132 lbs / 2.2 lbs/kg = 60 kg
Step 2: Calculate the Total Daily Dose
Ordered Dose: 0.5 mg/kg/day
Client Weight: 60 kg
Total Daily Dose: 0.5 mg/kg/day x 60 kg = 30 mg/day
Step 3: Determine the Number of Doses per Day
Doses are given every 6 hours.
Hours in a Day: 24 hours
Number of Doses: 24 hours / 6 hours/dose = 4 doses
Step 4: Calculate the Dose per Administration
Total Daily Dose: 30 mg/day
Number of Doses: 4 doses
Dose per Administration: 30 mg / 4 doses = 7.5 mg/dose
Step 5: Calculate the Volume to Administer per Dose
Dose per Administration: 7.5 mg
Concentration: 4 mg/mL
Volume to Administer: 7.5 mg / 4 mg/mL = 1.875 mL
Step 6: Round to the Nearest Tenth
The calculated volume is 1.875 mL.
Rounded to the nearest tenth: 1.9 mL
Answer: 1.9 mL
Correct Answer is ["0.2"]
Explanation
Convert the Client's Weight from Pounds to Kilograms:
1 kg = 2.205 lbs
Weight in kg = 138 lbs / 2.205 lbs/kg
Weight in kg ≈ 62.585 kg
Calculate the Total Dose of Darbepoetin Needed:
Dose = 0.75 mcg/kg x 62.585 kg
Dose ≈ 46.93875 mcg
Calculate the Volume of Darbepoetin to Administer:
Available concentration = 60 mcg/0.3 mL
To simplify, find the concentration per 1 mL: 60 mcg / 0.3 mL = 200 mcg/mL
Volume (mL) = Desired dose (mcg) / Available concentration (mcg/mL)
Volume (mL) = 46.93875 mcg / 200 mcg/mL
Volume (mL) ≈ 0.23469 mL
Round to the Nearest Tenth:
0.2 mL
