Setup / reasoning

30 × 2 ÷ 10 = 6 mL.

Answer

6 mL

Quick check

At a fixed concentration, a larger desired dose requires a proportionally larger volume.

Domain 2 of 12

Example

Available: 10 mg in 2 mL. The ordered dose is 30 mg. How many mL will deliver the ordered dose?

Setup / reasoning
? mL= 2 mL10 mg × 30 mg1
Target units stay on the left. The first factor on the right begins with the provided relationship that carries the target unit; matching units then cancel across the chain.
Answer

6 mL

Quick check

Unwanted units should cancel cleanly, leaving only the requested final unit.

Domain 5 of 12

CNA/CMA Clinical Support Math

CNA/CMA Clinical Support Math is included because it matches expected quantitative work for this provider level. CCMA scope emphasizes clinical medical assisting, oral/injectable medication calculations, conversions, and patient-care support; NHA medication tasks exclude intravenous administration.
8%MMM blueprint weight
Example

While checking a patient's pulse, you count 18 heartbeats in 15 seconds. What is the pulse rate in beats per minute?

Setup / reasoning

Multiply by 4 to scale the heartbeat count to one minute: 72 beats/min.

Answer

72 beats/min

Quick check

Scale the observed count to a full minute using the correct time multiplier.

Domain 6 of 12

Percentages

Percentages is included because it matches expected quantitative work for this provider level. CCMA scope emphasizes clinical medical assisting, oral/injectable medication calculations, conversions, and patient-care support; NHA medication tasks exclude intravenous administration.
8%MMM blueprint weight
Example

What is 25% of 80?

Setup / reasoning

25% × 80 = 20.

Answer

20

Quick check

The result should be the stated fraction of the whole; compare its magnitude with 0% and 100%.

Domain 7 of 12

Weight-Based Dosing

Weight-Based Dosing is included because it matches expected quantitative work for this provider level. CCMA scope emphasizes clinical medical assisting, oral/injectable medication calculations, conversions, and patient-care support; NHA medication tasks exclude intravenous administration.
8%MMM blueprint weight
Example

A 70 kg patient is ordered 0.1 mg/kg. What dose is ordered?

Setup / reasoning

70 × 0.1 = 7 mg.

Answer

7 mg

Quick check

Check that the weight unit matches the dose unit before multiplying.

Domain 8 of 12

Whole Number Operations

Whole Number Operations is included because it matches expected quantitative work for this provider level. CCMA scope emphasizes clinical medical assisting, oral/injectable medication calculations, conversions, and patient-care support; NHA medication tasks exclude intravenous administration.
7%MMM blueprint weight
Example

A supply area starts with 24 counted items, adds 18, then uses 11. How many remain?

Setup / reasoning

24 + 18 − 11 = 31.

Answer

31 items

Quick check

Reconcile the starting quantity, additions, and use; the ending count should fit the story.

Domain 9 of 12

Fractions / Decimals

Fractions / Decimals is included because it matches expected quantitative work for this provider level. CCMA scope emphasizes clinical medical assisting, oral/injectable medication calculations, conversions, and patient-care support; NHA medication tasks exclude intravenous administration.
6%MMM blueprint weight
Example

Setup / reasoning

Total intake is 360 mL; subtract 150 mL to get 210 mL.

Answer

210 mL

Quick check

Add all intake first, then subtract output; retain the sign because positive and negative balances mean different things.

Important scope note

Educational examples, not patient-specific clinical direction

These examples are designed to make quantitative relationships visible. They do not replace local protocols, medication references, device instructions, scope-of-practice requirements, official credentialing test plans, or clinical judgment. MedMathMindset uses the provider blueprint to organize math practice—not to redefine professional scope.
