ATI PN Dosage Calculations. Adult medical surgical proctored assessment 3.1 ( 25 Questions)
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.)
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.
