Dosage calculation question

Morning everyone!

I got this question wrong on a test, could someone tell me if I am losing it?

The drug label states that the usual dosage is 50-75 mcg/kg/day given in 2 divided doses. The client's weight is 43.8 kg.

What is the lower single dosage?

1095 mcg right? Am I losing it?

    If you use the exact weight 43.8 you are correct. If your program wanted you to round up you don't....

    43.8kg x 50mcg = 1095

    2 doses

    if however they wanted you to round up

    44kg x 50mcg = 1100

    2 doses

    We only round to the nearest tenth for weight, and that weight was provided, so I guess I will email the instructor. I just wanted to see if I was missing something before I made a fool out of myself. Thanks, Esme!

    Good job for not just rolling over and taking the points off. Too many times when I was in school people were too afraid to "fight" the question. I wasn't... there were a few times I gained 6 extra points on a test because I was not satisfied with the answer they gave us or the rationale. ;)

    Thanks! I posed it as a question, rather than saying "Hey this isn't wrong",

    I said "I thought I was supposed to divide the daily dose by 2, no?"

    It aggravates me, because I have a few professors who won't let us see our tests....I wonder how often that happens. :(

    Out of curiosity, with a weight based dosage, would you actually ever round up?

    I would ask your school and see what they say so you don't miss any questions. In real practice yes. If it is a cardiac kid or a toxic drug I will run it past the MD and pharmacy. But the usual round up or down applies. The smaller the child/infant, the toxicity of the drug.... the more I check
