1 Cardiovascular Assessment and ECG Fundamentals Online Quiz Questions

True or false: If a resting adult’s vital signs fall within common reference ranges, that alone proves the person is well.

A learner assumes that a standard 12-lead ECG requires 12 skin electrodes. Which correction is accurate?

At the standard ECG paper speed of 25 mm/s, how many seconds does one small horizontal box represent? Enter the value in seconds.

True or false: A normal-appearing ECG by itself is enough to rule out acute coronary syndrome.

A patient’s pulse feels irregular. Which action best follows the focused assessment guidance?

An ECG shows a fast, regular, narrow-complex rhythm, and P waves are difficult to see. What rhythm pattern is a common recognition possibility?

On a standard ECG, a regular rhythm has four large boxes between consecutive R waves. Using $\frac{300}{\text{number of large boxes}}$, what is the estimated heart rate?

Before interpreting an ECG tracing, which checks belong in the initial tracing-quality review? Select all that apply.

Which findings are reasons to activate emergency help? Select all that apply.

True or false: At standard ECG calibration, a vertical height of 10 mm represents 1 mV.

On standard ECG paper, how many small horizontal boxes make up one large box? Enter the number of small boxes.

An ECG shows an irregularly irregular ventricular rhythm with no consistent, organized P waves. Which rhythm clue does this pattern most strongly match?

What ECG component represents ventricular depolarization? Enter the component name.

On a standard ECG, a regular rhythm has 5 large boxes between consecutive R waves. Using the $\frac{300}{\text{number of large boxes}}$ method, what is the approximate heart rate?
