Macrodrip IV tubing has variable drop factors (10, 15, 20, or 12 gtts/mL) that exams always specify, while microdrip tubing is always 60 gtts/mL. You need to memorize the microdrip number because test questions may only say "microdrip" without stating it, expecting you to know it from memory.

When you get a question that says they are using macro drip tubing, that could be either 10, 12, 15 or 20 gtts. Okay? Per mil. So 10, 12, 15 or 20 drops per mil. That is for Macrodrip tubing. Now here's the tricky part. Micro. Microdrip tubing is only okay. Only. Only 60 drops per mil. Only. Okay? So when you get a dose count question, sometimes they will actually only tell you that they're using microdrip tubing. So sometimes they won't actually put the 60 drops per mil. Sometimes they will only say it's microdript tubing. And they expect you to know that that means 60 drops per mil. Okay? So that's just something. It's a really important thing to note. That definitely happened when I was in nursing school when I got to an exam. And man, I just remember thinking, oh, what was that? Like I know this. What was that number? It's 60. Okay, got it. 60. 60 drops per mil for a micro drip tubing. But macro drip can be 10, 12, 15 or 20. And when it is a macro drip tubing, just like this question says, they will specify. They will give you. They will give you it. They will give you the number. They have to because there's multiple options. But for a micro drip, it's only 6, 60. Okay, so if this question said micro drip tubing, then we would have put in the 60 drops per mill.
