The healthcare provider prescribes interferon beta-1b 0.25 mg SUBQ every other day for a client with multiple sclerosis. The nurse reconstitutes the single-use vial of powder labeled, "0.3 mg with 1.2 mL of sterile water." How many mL should the nurse administer to the client? (Enter the numerical value only.)
The Correct Answer is ["1"]
Calculation:
Determine the concentration of the reconstituted solution:
Concentration (mg/mL) = Total amount of drug (mg) / Total volume after reconstitution (mL)
= 0.3 mg / 1.2 mL
= 0.25 mg/mL
Identify the prescribed dose = 0.25 mg
Calculate the volume to administer:
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
= 0.25 mg / 0.25 mg/mL
= 1 mL

Correct Answer is ["0.9"]
Explanation
Calculation:
Identify the desired dose:
Desired dose = 90 mg
Identify the available concentration:
Available concentration = 100 mg / 1 mL
Calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 90 mg / 100 mg/mL
= 0.9 mL
Correct Answer is ["8"]
Explanation
Calculation:
Dose per administration = 20 mg
Available dose per tablet = 10 mg/tablet
Calculate the number of tablets to administer per dose:
Tablets per dose = Dose per administration / Available dose per tablet
= 20 mg / 10 mg/tablet
= 2 tablets
Calculate the total number of tablets to administer in a 24-hour period:
Total tablets per day = Tablets per dose x Number of doses per day
= 2 tablets/dose x 4 doses/day
= 8 tablets
