How many times should a medical assistant check the label on an irrigating solution to make
sure it has the right name, expiration date, and concentration?

3/4 times per day. To check for pt’s information

The answer would be true.

You did not show us the image of the burger, but i shall try to answer as best i can.  when purchasing food, always consider the ingredients as well as the person who prepared it. consider if they were hygienic people or not, in case the burger was infected with bacteria. no mortal should place an infected burger into their mouth.
