Mastering TEAS ATI Mathematics: Understanding Staff Certification Percentages

What percentage of the total staff is certified and available to work in the neonatal unit if 35% are unavailable and 20% of the remaining are certified?

• A. A. 7%
• B. B. 13%
• C. C. 65%
• D. D. 80%

Answer: (B)

To determine the percentage of the total staff that is certified and available to work in the neonatal unit, we first need to analyze the staff's availability and certification status. Starting with the total staff, if 35% are unavailable, this means that 65% of the staff is available to work. Now, we focus on the available staff. Out of this 65%, it is given that 20% are certified. To find the actual percentage of the total staff that is both certified and available, we take 20% of the 65% that is available. This can be calculated as follows: 1. Calculate the percentage of the total staff that is available: - Available staff = 100% - 35% = 65%. 2. Calculate the certified staff from the available pool: - Certified staff = 20% of available staff = 20% of 65%. To perform this calculation: 20% of 65% = 0.20 × 65 = 13%. Therefore, the percentage of the total staff that is certified and available to work in the neonatal unit is 13%. This aligns with the answer choice selected, confirming its correctness and helping clarify how the percentage was derived.

When preparing for the TEAS ATI Mathematics test, students often encounter real-world scenarios that require not just rote memorization but a deep understanding of how to manipulate percentages and other mathematical concepts. Let’s break down a question about staff certification that could easily pop up in your test prep.

Imagine this: you’re asked to calculate what percentage of the total staff is certified and available to work in the neonatal unit. Not only does this require basic math skills, but it also asks you to process information about availability and certification rates — something that all aspiring nursing professionals should get comfortable with.

Here’s the setup: 35% of the staff is unavailable. That leaves 65% available to work. But wait, there’s more! Out of this available group, we learn that 20% are certified. So, what do you do? Here’s a handy step-by-step approach to making sense of this.

First, let’s focus on the numbers. If 35% of the staff is unavailable, that means the remaining 65% is available. You’ve got to get that number fixed in your mind because it’s your starting point. Once you have that, think about what 20% of this 65% looks like.

You see, this is where math often feels like tackling a puzzle. Want to solve it? Let me explain.

1. Start from the total staff. We know that with 35% unavailable, we're left with 65% who are available.

2. Now, out of that 65%, we need the certified portion. So, how do we find 20% of 65%? It’s pretty simple once you do the math: 0.20 times 65, which equals 13.

This is where you can even hear a cheer from some of your fellow test-takers who find this type of calculation somewhat satisfying!

So, what’s the takeaway? The percentage of the total staff that is certified and ready to jump in at the neonatal unit is a neat 13%. Solid understanding of math concepts like this can make a world of difference — not just on your TEAS test, but also in your future career in nursing.

Always remember, math doesn’t have to be daunting. With practice and a little patience, these types of questions will feel like second nature! Plus, knowing the steps can bolster your confidence, not just for your exams but also in practical, in-the-field scenarios.

The TEAS ATI Mathematics test often blends these kinds of questions into realistic contexts, so keep honing those skills. Whether it's patient care or staff management, the math you learn here will stick with you, helping to make those future decisions easier.

So next time you tackle a percentage question, you’ve got a handy toolkit to pull from. Feel empowered, curious, and ready to solve whatever math challenges come your way.
