Quick Study Guide — Key Concepts by Subject

Mathematics Key Formulas

Dosage Formula: Desired Dose ÷ Dose on Hand × Volume = Amount to Give
IV Drip Rate: Volume (mL) ÷ Time (min) × Drop Factor = gtt/min
Percentage: Part ÷ Whole × 100
Ratio/Proportion: a/b = c/d → cross-multiply to solve
Unit Conversion: 1 kg = 2.2 lbs · 1 inch = 2.54 cm · 1 oz = 30 mL
Temperature: °C = (°F – 32) × 5/9 · °F = (°C × 9/5) + 32

Biology Quick Reference

Cell Organelles: Nucleus (DNA) · Mitochondria (energy/ATP) · Ribosome (protein synthesis) · ER (transport) · Golgi (packaging) · Lysosome (digestion)
DNA → RNA → Protein: Transcription (DNA to mRNA) → Translation (mRNA to Protein)
Mitosis Phases: PMAT — Prophase, Metaphase, Anaphase, Telophase
Meiosis: Produces 4 haploid cells for sexual reproduction
Punnett Square: Dominant (B) × Recessive (b): BB, Bb, Bb, bb (3:1 ratio)

Anatomy & Physiology Essentials

Heart: RA → Tricuspid → RV → Pulmonary → Lungs → Pulmonary Veins → LA → Bicuspid/Mitral → LV → Aortic → Body
Normal HR: 60–100 bpm · Normal BP: 120/80 · Normal RR: 12–20 bpm
Cranial Nerves: 12 pairs — "Oh Oh Oh To Touch And Feel Very Good Vagus Absolutely Heavenly" (mnemonics)
Bones: 206 total — 80 axial + 126 appendicular
Endocrine: Pituitary (master gland) · Thyroid (T3, T4 — metabolism) · Adrenal (cortisol, aldosterone) · Pancreas (insulin, glucagon)

Chemistry Fundamentals

pH Scale: 0–6 = Acid · 7 = Neutral · 8–14 = Base/Alkaline
Blood pH: Normal 7.35–7.45 (slightly alkaline)
Atomic Number: Number of protons in nucleus
Ionic Bond: Metal + Nonmetal (electron transfer)
Covalent Bond: Nonmetal + Nonmetal (electron sharing)
Hydrogen Bond: Between H and N, O, or F (water cohesion, DNA base pairs)

Physics for HESI

Newton's 1st Law: An object at rest stays at rest unless acted upon by a force
Newton's 2nd Law: Force = Mass × Acceleration (F = ma)
Newton's 3rd Law: For every action there is an equal and opposite reaction
Ohm's Law: Voltage = Current × Resistance (V = IR)
Work: W = Force × Distance · Power = Work / Time
Sound: Frequency (Hz) determines pitch; Amplitude determines volume

Top Test-Taking Strategies

Read every question completely before looking at options — keywords matter
Use process of elimination — remove 2 wrong answers first
In math, always check your work by plugging the answer back in
For vocabulary, use context clues and prefix/suffix knowledge
Don't overthink — your first instinct is often correct
Flag and skip hard questions, return to them last
Manage time: aim for ~75 seconds per question
On exam day: sleep 8 hrs, eat a full breakfast, arrive 30 min early

Student Reviews

★★★★★

"I scored 89% overall! The A&P module was incredibly detailed and the practice tests were very similar to the actual exam."

— Maria T., Nursing Student

★★★★★

"Failed the HESI twice before this course. Retook it after 6 weeks of prep and scored 84%. The math module saved me!"

— James R., Pre-Nursing
