While doing practice questions for the NCLEX, I got confused on this one, can anyone enlighten me? thanks
A physician prescribes 1000 mL of 5% dextrose in water containing 1.5 mEq of KCl per 100 mL to infuse at a rate of 110 mL per hour.
At 7:00 am, the nurse hangs the solution
at 11:00 am, how much KCl has the client received?
thanks guys.

That's the total volume of the fluids, but I think the question wants how much KCl specifically. If the patient received 440 mL of fluid and there are 1.5 mEq KCl in every 100 mL of fluid... the answer should be clearer from there.
yep 440 cc but your halfway through the computation.
the question is asking about how much KCl the patient received from that 440 cc.
the cd gave an explanation, but to me it didn't make sense, i was .2 near the answer.
anyone?

i think the correct answer is 6.6.am i right guys?
im good at math so i guess i got it right with 6.6 kcl.100 ml contains 1.5 kcl. the patient received 440ml in 4 hours.there are 6kcl in 400ml.in order for us to get the kcl content in the remaining 40ml we divide 100 by 1.5 then multiply the answer by 40.
correct. I better understood it thanks to you. hehe. what i did was 100 divide buy 1.5
and multiplied by 40. WRONG. it should have been 1.5 divide by 100 then times 40. thanks for the input. back to reviewing for me.
im from d phil also.. hehe.. i took nclex pn on sept.22 and i passed it.anyway it was just nclex pn

It's 110mls X 4 hours. Always take the ML's x #hours. in this case the bag was hanging 4 hours.
