Here's how you did. And what it means.
These aren't just answers. They're a window into what dosage calc actually tests.
But before you check off your answers, here's one thing I want you to keep in mind: these ten questions weren't random. Each one was chosen to represent a different type of dosage calculation you'll encounter in nursing school and at the bedside. So as you read through the answers, pay attention to the coaching note under each one — that's where the real learning lives.
Melissa
Answer: 3 Tablets
Coaching: This looks like a simple tablet calculation, but there's a reading comprehension trap built in. The question tells you Melissa's dose changes over time — week 4 puts her in the twice-daily phase, meaning you're calculating for 300 mg total, not 150 mg. If you solved for the wrong dose, that's the most common mistake here: rushing past the clinical context to get to the math.
Calvin
Answer: 0.9 ml
Coaching: This one requires careful attention to unit conversions to ensure you've set things up correctly. Calvin's dose is ordered in micrograms, but the medication vial is labeled in milligrams. Students who miss this step will be off by a factor of 1,000. Always check that your units match and all cancel out before you multiply.
Ms. Camposagrado
Answer: 100 ml/hr
Coaching: Welcome to IV rate calculations! The key insight here is treating time as part of the equation — 30 minutes becomes 0.5 hours, which flips the rate cleanly. If you got a number that felt too high or too low, check how you handled the time conversion first.
Ms. Camposagrado
Answer: 333 mg
Coaching: Notice that Ms. Camposagrado appears twice...that's intentional. At the bedside, a single patient scenario can generate multiple calculation questions in rapid succession. Here you're calculating how much medication she received before the infusion was stopped. This type of question requires you to think in mg/min, not just total dose.
Jeremy
Answer: 1.5 tablets at 0300 (3:00 AM)
Coaching: Two skills tested in one question: the tablet calculation itself, and the ability to advance time in military clock format. Many students get the tablet math right and stumble on the clock. If 2100 + 6 hours gave you any pause, that's worth practicing because time-based questions show up constantly in clinical.
Shawna
Answer: 6.67 ml
Coaching: The loading dose in this question is a deliberate distraction. You only need the maintenance dose of 200 mg to solve the problem. The 500 mg loading dose is information you don't use. Learning to identify and set aside irrelevant data is one of the most underrated dosage calculation skills, and nursing exams test it regularly.
History of Nursing
Answer: 84.2 oz and 5 venti coffees
Coaching: Yes, this one was a little fun. 
But the skill is real: unit conversion across measurement systems. You had to move from grams to milligrams, then calculate volume, then apply rounding rules differently for each part of the answer (nearest tenth for ounces, round up for coffees). Multi-part questions with different rounding instructions are a staple of nursing exams, and so is calculating cumulative dose.
Elissa
Answer: 1.2 ml
Coaching: This is a reconstitution question, which trips students up because the concentration after mixing isn't printed on the label, you have to calculate it first. The vial instructions tell you to add 1.8 ml to arrive at 500 mg/2 ml. Once you establish that concentration, the rest solves like any other liquid calculation.
Riley
Answer: 0.12 ml
Coaching: This is a weight-based pediatric calculation, and the small numbers are the point. Riley weighs 830 grams (not kilograms) which means your very first step is a unit conversion before you can calculate the dose. In pediatric and neonatal nursing, this kind of precision is non-negotiable. A misplaced decimal here is a serious medication error.
Tom
Answer: 102 mcg
Coaching: This is the most clinically complex question in the set, and deliberately so. Tom is unarousable and your job is to figure out exactly how much fentanyl he's received. To do this, you have to calculate his basal dose over two hours (8 ml/hr × 2 hrs = 16 ml), add his 7 bolus doses (7 × 5 ml = 35 ml), arrive at 51 total ml, then apply the concentration (2 mcg/ml) to get 102 mcg. The math isn't the hard part. Staying organized under pressure — and recognizing that an unarousable patient with a PCA is a clinical emergency — is the real skill being tested here. Good job!
So...what does this mean for you?
Wherever you landed, there's a clear next step.
You nailed most of them 🎉
Strong work. Your foundation is solid, but the questions only get more complex from here with multi-step problems, weight-based drips, and distractors designed to throw you off. Confident Calculations will make sure your method is airtight so you walk into that exam ready for whatever they throw your way.
You got about half of them 🤔
You struggled with most of them 
Take a breath. This is exactly why the practice questions exist. You want to find the gaps now, not on exam day. What you need isn't more random practice problems. You need a systematic method that makes the process almost impossible to get wrong. That's exactly what Confident Calculations teaches.
A focused, step-by-step program that teaches you a reliable process for every type of dosage calculation from basic tablet math to complex weight-based IV drips. No math background required.
Hi! I'm Maureen (Nurse Mo). And I used to be terrified of math, too.
I'm not just saying that to make you feel better. I genuinely dreaded math all through high school and college. In my first undergraduate program, it was the thing that loomed over everything. I was convinced I was just "not a math person," and I carried that belief around like it was fact.
But when I decided to pursue nursing, I knew something had to shift. I stopped telling myself I couldn't do it and started asking myself what it would look like if I could. That mindset shift changed everything. I didn't just get through the math — I thrived. In fact, I loved algebra to a degree that I'm pretty sure made me an official, bona-fide nerd. And somewhere along the way, the thing I once dreaded became something I love to teach.
While I was once that student who "wasn't a math person," I am now someone that has taught thousands of students how to do dosage calculations. And the number one thing I see holding students back isn't ability. It's the story they're telling themselves about what they're capable of.
If you picked up the "Kick Math Anxiety to The Curb" guide because medical math scares you, I want you to hear this directly from someone who has been exactly where you are: you can do this. And you will do this.
I believe in you!
Cheering for you always,
Nurse Mo
