Cheat Sheet

  1. EKG Waveforms and Intervals -

    Reviewing EKG waveforms - P wave, QRS complex, and T wave - ensures you can identify each deflection on RMA exam questions. According to American Heart Association guidelines, the PR interval should be 0.12 - 0.20 seconds and the QRS duration less than 0.10 seconds to indicate normal conduction.

  2. Calculating Heart Rate on ECG Strips -

    Master the 300 method (300 divided by the number of large boxes between R waves) for regular rhythms and the 1,500 method (1,500 divided by small boxes) for precise counts in your RMA certification quiz. These quick calculations are indispensable for identifying tachycardia or bradycardia on medical assistant exam questions.

  3. Interpreting a Standard Lipid Panel -

    Know normal values - total cholesterol <200 mg/dL, HDL >60 mg/dL, LDL <100 mg/dL, triglycerides <150 mg/dL - per National Institutes of Health guidelines to tackle medical assistant exam questions. Remember: higher HDL is protective, while elevated LDL and triglycerides increase cardiovascular risk.

  4. Estimating LDL with the Friedewald Equation -

    Use the formula LDL (mg/dL) = Total Cholesterol - HDL - (Triglycerides/5) to calculate LDL quickly in RMA practice test scenarios. This equation, endorsed by the American College of Cardiology, helps you interpret lipid panels when direct LDL measurement isn't available.

  5. Mastering Unit Conversions via Dimensional Analysis -

    Apply the mnemonic "King Henry Died By Drinking Chocolate Milk" to recall kilo-, hecto-, deca-, base, deci-, centi-, milli- for seamless RMA test prep. For example, converting 0.25 g to milligrams: 0.25 g × (1,000 mg/1 g) = 250 mg.
