  6. Identify the days supply: Dispense 120 tablets; directions are 2 tablets twice daily.
    30 days30\ \text{days}. Divides 120 tablets by 4 tablets daily (2 twice daily) to find the supply duration.
  7. Identify the total inhalations used in 30 days: Use 2 inhalations four times daily.
    240 inhalations240\ \text{inhalations}. Multiplies 2 inhalations per dose by 4 doses daily and 30 days for total inhalations.
  8. Identify the total tablets for a taper: 4 tabs daily x 3 days, then 2 tabs daily x 3 days.
    18 tablets18\ \text{tablets}. Adds products of daily tablets and days for each taper phase to compute the overall total.
  9. What is the formula for total quantity when the regimen is expressed as doses per day?
    total units=units/dose×doses/day×days\text{total units} = \text{units/dose} \times \text{doses/day} \times \text{days}. Multiplies units per dose by doses per day and then by total days to compute the overall quantity required.
  10. Identify the total mL needed: Take 5 mL by mouth twice daily for 10 days.
    100 mL100\ \text{mL}. Multiplies 5 mL per dose by 2 doses daily and 10 days to determine the total volume required.
  11. Identify the number of inhalers: Need 240 inhalations; each inhaler provides 120 inhalations.
    2 inhalers2\ \text{inhalers}. Divides 240 required inhalations by 120 per inhaler to determine the number needed.
  12. Identify the infusion time (hours): Volume is 1000 mL at a rate of 125 mL/hour.
    8 hours8\ \text{hours}. Divides the 1000 mL volume by the 125 mL per hour rate to calculate the infusion duration.
  13. What is the formula for quantity (tablets) from a dose in mg and strength in mg/tablet?
    tabs=mgmg/tab\text{tabs} = \frac{\text{mg}}{\text{mg/tab}}. Divides the required dose in milligrams by the tablet strength to calculate the number of tablets per dose.
  14. Identify the total capsules needed: Take 2 capsules three times daily for 7 days.
    42 capsules42\ \text{capsules}. Multiplies 2 capsules per dose by 3 doses daily and 7 days to find the total capsules needed.
  15. Identify the days supply: Dispense 300 mL; directions are 10 mL three times daily.
    10 days10\ \text{days}. Divides 300 mL by 30 mL daily (10 mL three times) to calculate the days supply.
  16. Identify the total mL needed: Infuse at 75 mL/hour for 8 hours.
    600 mL600\ \text{mL}. Multiplies the infusion rate of 75 mL per hour by 8 hours to find the total volume infused.
  17. Identify the number of tablets per dose: Order is 75 mg; strength is 25 mg/tablet.
    3 tablets3\ \text{tablets}. Divides the 75 mg dose by the 25 mg per tablet strength to calculate tablets per dose.
  18. What is the formula for mL per day from directions expressed as mL per dose and doses per day?
    mL/day=mL/dose×doses/day\text{mL/day} = \text{mL/dose} \times \text{doses/day}. Multiplies the volume per dose by the number of doses per day to calculate the total daily liquid consumption.
  19. Identify the quantity to dispense (g): Apply 2 g topically daily for 30 days.
    60 g60\ \text{g}. Multiplies 2 grams daily by 30 days to determine the total grams for the topical regimen.
  20. Identify the volume (mL) needed: Dose is 30 units; concentration is 100 units/mL.
    0.3 mL0.3\ \text{mL}. Divides the 30 units dose by the 100 units per mL concentration to find the injection volume.
  21. Identify the mL per dose: Order is 250 mg; product concentration is 50 mg/mL.
    5 mL5\ \text{mL}. Divides the 250 mg dose by the 50 mg/mL concentration to find the volume per dose.
  22. Identify the total tablets for a taper: 3 tabs daily x 2 days, then 2 daily x 2 days, then 1 daily x 2 days.
    12 tablets12\ \text{tablets}. Sums the products of tablets per day and days across all tapering stages for the total quantity.
  23. Identify the total units needed: Inject 18 units subcutaneously once daily for 28 days.
    504 units504\ \text{units}. Multiplies 18 units daily by 28 days to determine the total units for the subcutaneous regimen.
