A nurse is preparing to administer 0.5 mg haloperidol PO to a client. Available is haloperidol 500 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 ["1"]
The nurse should administer 1 tablet of haloperidol.
Step-by-Step Calculation
Understanding the Problem
Desired haloperidol dose: 0.5 mg
Available tablets: 500 mcg each
We need to find the number of tablets to administer.
Calculations
Convert milligrams to micrograms:
1 mg = 1000 mcg
0.5 mg = 0.5 X 1000 = 500 mcg
Calculate the number of tablets:
Number of tablets = Desired dose (mcg) / Tablet strength (mcg)
Number of tablets = 500 mcg / 500 mcg/tablet = 1 tablet
The nurse should administer 1 tablet of haloperidol.
