Question

7. A patient has a urinary tract infection so Dr. Padron prescribes Ancef. A 1200 mL bag contains 400 mg of Ancef. If the patient receives 600 mL of fluid, how many mg of Ancef did the patient receive?

Answer 1

Answer:

  200 mg

Step-by-step explanation:

The dose (d) is proportional to amount of fluid received, so ...

  d/(600 mL) = (400 mg)/(1200 mL)

  d = (600 mL)(400 mg)/(1200 ml)

  d = 200 mg

The patient received 200 mg of drug.
