(Enter the numerical value only. If rounding is required round to the nearest hundredth)
The Correct Answer is ["0.75"]
The healthcare provider prescribes interferon beta-1b 0.1875 mg 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, so the concentration of interferon beta-1b in the solution is 0.25 mg/mL (0.3 mg / 1.2 mL).
Since the healthcare provider prescribes 0.1875 mg of interferon beta-1b, the nurse should administer 0.75 mL of medication (0.1875 mg / 0.25 mg/mL).

Correct Answer is ["18"]
Explanation
The client is to receive furosemide 60 mg every 12 hours.
The drug is available in a concentration of 10 mg/mL, so the nurse should administer 6 mL of medication (60 mg / 10 mg/mL).
The nurse plans to administer the dosage over 20 minutes, so the infusion rate should be 18 mL/hour (6 mL / (20 minutes / 60 minutes/hour)).
Correct Answer is ["2"]
Explanation
The client receives a prescription for digoxin 125 mcg by mouth daily. Since 1 mg is equivalent to 1000 mcg, 125 mcg is equivalent to 0.125 mg.
The medication is available in 0.0625 mg tablets, so the nurse should administer 2 tablets (0.125 mg / 0.0625 mg/tablet).
