Tim is a nursing assistant who checked the patients’ blood sugar. He noticed that all of the patients that day had high blood sugar and realized that he needed to check the blood glucose monitor to make sure it was not malfunctioning. What should Tim have done differently? read the instructions on the meter
checked the meter before using it
worked with another nursing assistant
used two meters per patient to be sure

Checked the meter before using it

Explanation:

The text says that Tim only realized that he had to check the equipment after noticing that all the patients for the day had high blood sugar levels. This was a bit reckless of him because he should have checked the equipment before he started using it for the day.

This is a very important concept in medicine because a malfunctioning equipment could be the difference between life and death and so it is important that such things are noticed ahead of time.
