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.)

Answer and Explanation

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.

Correct Answer is ["1.5"]

Explanation

To calculate the dosage of cefazolin, the nurse needs to use the following formula:

Dose (mL) = Ordered dose (mg) / Available dose (mg/mL)

Plugging in the values from the question, we get:

Dose (mL) = 500 mg / 330 mg/mL

Dose (mL) = 1.515 mL
Rounding to the nearest tenth, the nurse should administer 1.5 mL of cefazolin per dose.

Correct Answer is ["3"]

Explanation

To calculate the dose of calcitonin for a client who weighs 165 lb, the nurse needs to convert the weight to kilograms first.

One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 165 / 2.2 = 75 kg.

The prescribed dose is 8 units/kg, so the total dose is 8 x 75 = 600 units.

The available concentration is 200 units/mL, so the volume to administer is 600 / 200 = 3 mL.

The nurse should administer 3 mL of calcitonin IM to the client.
