A patient is to receive medroxyprogesterone (Depo-Provera) 700 mg weekly, intramuscularly, as part of palliative therapy for endometrial cancer. The medication is available in vials of 400 mg/mL. Identify how many milliliters will the nurse draw up and administer with each injection. (record answer using one decimal place)
Correct Answer: 1.8 mL
Rationale: To calculate: 400 mg/1 mL = 700 mg/x mL. Cross-multiply: (400 * x) = (1 * 700); 400x = 700; x = 700/400 = 1.75 mL, rounded to 1.8 mL.
