A nurse preparing to administer diciofenac sodium 200 mg PO daily equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading, zero if it applies. Do not use a trailing, zero.)

Determine the total daily dosage: The client is prescribed 200 mg of diclofenac sodium daily. Calculate the dosage per dose: The medication is to be administered in equally divided doses every 6 hours. There are 24 hours in a day, so the medication is given 24/6 = 4 times a day. The dosage per dose is 200 mg / 4 doses = 50 mg per dose.
