A nurse is preparing to administer adenosine 12 mg IV bolus to a client. Available is adenosine injection 60 mg/20 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
Calculation:
Determine the desired dose:
Ordered dose: 12 mg
Determine the available concentration of the medication:
Available concentration: 60 mg / 20 mL
Calculate the volume needed to administer the desired dose:
Formula: Volume (mL) = Desired dose (mg) × (Volume of solution (mL) / Available dose (mg))
= 12 mg × (20 mL / 60 mg)
= 240 mL / 60
= 4 mL

Correct Answer is A
Explanation
A. The medication can be used for IV administration: The label clearly states that the medication is for intramuscular or intravenous use only. This means the medication is indeed suitable for IV administration.
B. The medication can be used for up to 14 days after reconstitution: The label specifically mentions that the reconstituted medication should be used within 48 hours. This is less than 14 days.
C. The medication should be reconstituted with 0.9% sodium chloride solution: The label specifies that the medication should be reconstituted with bacteriostatic water for injection, not 0.9% sodium chloride solution.
D. The vial contains a single dose: The label indicates that this is a multiple dose vial, meaning it contains more than one dose.
Correct Answer is ["285"]
Explanation
Calculation:
Convert the client's weight from pounds (lbs) to kilograms (kg):
Formula: Weight in kg = Weight in lbs / 2.2 lbs/kg
= 167 lbs / 2.2 lbs/kg
≈ 75.91 kg
Calculate the total dose of amphotericin B lipid complex needed:
Ordered dose: 3.75 mg/kg
Client's weight in kg: ≈ 75.91 kg
Formula: Total dose (mg) = Ordered dose (mg/kg) × Client's weight (kg)
= 3.75 mg/kg × 75.91 kg
≈ 284.66 mg
Determine the concentration of the available amphotericin B lipid complex solution:
Available amount: 300 mg
Volume of solution: 300 mL
Formula: Concentration (mg/mL) = Total amount (mg) / Total volume (mL)
= 300 mg / 300 mL
= 1 mg/mL
Calculate the volume of solution to administer:
Formula: Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
= 284.66 mg / 1 mg/mL
= 284.66 mL
Round the answer to the nearest whole number:
284.66 mL rounded to the nearest whole number is 285 mL.
