I'm going with C, 150 mL. It's the only option that seems reasonable for a 10-day treatment. Unless the patient is a camel, then maybe 200 mL would work.

75 mL? Are you kidding me? That's barely enough for two days. This exam is trying to trip us up with these weird doses.

200 mL? That's way too much. I bet the pharmacist would start questioning my math skills if I wrote that on the label.

Hmm, 150 mL sounds about right. Gotta make sure the patient has enough to last the full 10 days, you know?

I think the answer is 100 mL. That's the right amount to dispense for a 250 mg dosage four times a day for 10 days.

I'm not sure, but I think the answer might be C) 150, because 2500 mg divided by 250 mg per 5ml equals 50ml, which is 150ml for 10 days.

I agree with Onita, because 250 mg qid x 10 days equals 2500 mg total, which is 10 doses of 250 mg each.
