A nurse is preparing to administer mycostatin 400,000 units PO every 6 hr. Available is mycostatin oral suspension 100,000 units/mL. How many mL should the nurse administer per dose? (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 ["4"]
To calculate the dose of mycostatin oral suspension, the nurse needs to divide the prescribed amount of units by the concentration of units per mL.
In this case, the nurse should divide 400,000 units by 100,000 units/mL, which gives 4 mL.
The nurse should administer 4 mL of mycostatin oral suspension every 6 hours as ordered.

Correct Answer is ["500"]
Explanation
To calculate the infusion rate for lactated Ringer's solution, the nurse should use the following formula: infusion rate (mL/hr) = volume (mL) / time (hr).
Since the volume is 250 mL and the time is 0.5 hr (30 min), the infusion rate is 250 / 0.5 = 500 mL/hr.
The nurse should set the IV pump to deliver 500 mL/hr of lactated Ringer's solution to the patient.
Correct Answer is ["0.2"]
Explanation
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.
