Question 7
5 pts
You want to compare a patient's measured calcium ion concentration to the normal calcium ion concentration in blood
serum. The only range you can find is 4.5 5.5 mEq/L, but the blood results show a concentration of 0.19 mmol/dL.
Convert the measured calcium ion concentration from the blood results to mEq/L (to one decimal place). Do not input
units on the Canvas answer, but they should be visible on your uploaded file.
