A nurse is assisting with the care of a client who is experiencing postpartum bleeding. The nurse is preparing to administer methylergonovine 0.4 mg PO. Available is methylergonovine 200 mcg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
1 mg = 1000 mcg
Prescribed dose: 0.4 mg Converted to mcg: 0.4 mg x 1000 = 400 mcg
Available tablets: 200 mcg each
Next, we divide the prescribed dose by the strength of the available tablets:
400 mcg / 200 mcg per tablet = 2 tablets
