A nurse is preparing to administer methotrexate 7.5 mg subcutaneous for a client who has rheumatoid arthritis. Available is methotrexate 15 mg/0.4 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.2"]

To calculate the dosage of methotrexate for a client who has rheumatoid arthritis, the nurse needs to use the following formula:

D/H x Q = X, where D is the desired dose, H is the dose on hand, Q is the quantity of the solution, and X is the amount to administer.

In this case, D is 7.5 mg, H is 15 mg, and Q is 0.4 mL.

Plugging these values into the formula, we get: 7.5/15 x 0.4 = 0.2.

Therefore, the nurse should administer 0.2 mL of methotrexate subcutaneously for the client.

Correct Answer is ["2"]

Explanation

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 ["2"]

Explanation

To give a loading dose of ketorolac 30 mg IM, the nurse needs to calculate the volume of the injection solution.

The solution has a concentration of 15 mg/mL, which means that every 1 mL contains 15 mg of ketorolac.

To find the volume, the nurse can use the formula: volume = dose / concentration. Plugging in the values, we get: volume = 30 mg / 15 mg/mL = 2 mL.

Therefore, the nurse should administer 2 mL of ketorolac injection for a loading dose.
