The healthcare provider prescribes penicillin V potassium 650,000 units IM. The available vial is labeled, "Penicillin V potassium 500,000 units/mL." How many mL should the nurse administer? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.3"]
Calculation:
Formula:
Volume to administer (mL) = Desired dose (units) / Available concentration (units/mL)
Desired dose = 650,000 units
Available concentration = 500,000 units/mL
Volume to administer (mL) = Desired dose (units) / Available concentration (units/mL)
= 650,000 units / 500,000 units/mL
= 1.3 mL

Correct Answer is ["15"]
Explanation
Total amount of liraglutide in the pen = 18 mg
Prescribed dose = 1.2 mg per day
Calculate the number of doses available in each pen:
Number of doses = Total amount in pen / Prescribed dose per day
= 18 mg / 1.2 mg/dose
= 15 doses
Correct Answer is ["2.6"]
Explanation
Calculate the prescribed dose in micrograms:
Dose (mcg) = Prescribed dose (mcg/kg) x Client's weight (kg)
= 44 mcg/kg x 60 kg
= 2640 mcg
Convert the dose from micrograms to milligrams:
Dose (mg) = Dose (mcg) / 1000 mcg/mg
= 2640 mcg / 1000 mcg/mg
= 2.64 mg
Round to the nearest tenth:
Rounded dose = 2.6 mg
