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.)
The Correct Answer is ["2"]
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.

Explanation
To calculate the dosage of tobramycin for a client who weighs 85 kg, first we need to find the total daily dose by multiplying the weight by the dose per kg: 85 kg x 3 mg/kg/day = 255 mg/day.
Then, we need to divide the total daily dose by the number of doses per day to get the dose per administration: 255 mg/day / 3 doses/day = 85 mg/dose.
Finally, we need to use the concentration of the available solution to find the volume per dose by dividing the dose by the concentration: 85 mg/dose / 40 mg/mL = 2.125 mL/dose.
The nurse should administer 2.1 mL of tobramycin per dose to the client.
