HOSA Medical Math Practice Test Cheat Sheet
- Master Metric Conversions - Grasping that 1 kilogram equals 1,000 grams and 1 liter equals 1,000 milliliters is the backbone of medical math. Nailing these basics ensures you'll hit the correct dosage every time and avoid slippery calculation mistakes.
- Convert Household Measurements - Think of your kitchen as a mini pharmacy: 1 teaspoon is 5 mL and 1 ounce is 30 mL. These handy conversions turn confusing recipe-style dosages into clear, precise instructions.
- Pediatric Dosage with Clark's Rule - Use Clark's Rule (Child's Dose = [Weight in lb / 150] × Adult Dose) to tailor meds for little patients. This quick formula helps you adjust adult doses safely for kids, so you're always in the right ballpark.
- Infusion Rate Calculations - Calculate drip rates with Volume (mL) / Time (hr) = Rate (mL/hr). This ensures IV fluids and meds flow at just the right speed - no floods or famines in the veins!
- Dimensional Analysis Magic - Let units do the heavy lifting: cancel out unwanted measurements and watch conversions fall into place. It's like a party where only the right units get an invite, leaving no room for errors.
- Solution Strengths & Ratios - Decode 1:1000 (1 g in 1,000 mL) or understand that 5% means 5 g per 100 mL. Mastering these ratios and percentages makes mixing meds feel like alchemy.
- Temperature Conversions - Swap between Celsius and Fahrenheit with F = 1.8×C + 32 and C = (F - 32) / 1.8. Getting the temp right can be lifesaving in critical care scenarios.
- Body Surface Area (BSA) - Use BSA (m²) = √([Height(cm) × Weight(kg)] / 3600) to fine-tune chemo and other dose‑critical drugs. It's the golden ticket to personalized medication.
- Rounding Rules - Round 2.76 to 2.8 when going to the nearest tenth, and always follow institutional policies. Correct rounding keeps dosages safe and doesn't shortchange your patients.
- Medical Abbreviations & Symbols - Decode "mg" for milligrams, "mL" for milliliters, and beyond. Familiarity with these abbreviations stops misinterpretation dead in its tracks.
