A nurse is preparing to administer levothyroxine 150 mcg PO. Available is levothyroxine 75 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.)

To give the correct dose of levothyroxine, the nurse needs to calculate how many tablets of 75 mcg are equivalent to 150 mcg. The nurse can use a proportion to solve this problem. Let x be the number of tablets to administer. Then, the proportion is: 75 mcg / 1 tablet = 150 mcg / x tablets Cross-multiplying, we get: 75x = 150 Dividing both sides by 75, we get: x = 2 Therefore, the nurse should administer 2 tablets of levothyroxine 75 mcg to give a total of 150 mcg.
