Question

The nurse is interpreting the rhythm strip of a patient and measures the QRS complex as being three small boxes in width. The nurse interprets this width as

A) 0.12 seconds.
B) 0.16 seconds.
C) 0.04 seconds.
D) 0.10 seconds.

Answer 1

The width of the QRS complex, measured as three small boxes on an ECG, equates to a duration of 0.12 seconds.

Step-by-step explanation:

The nurse is interpreting the rhythm strip of a patient and measures the QRS complex as being three small boxes in width. According to standard ECG paper, where each small box represents 0.04 seconds, the measurement of three small boxes would correspond to a QRS complex width of 0.12 seconds. It is essential to accurately interpret the duration of the QRS complex as it reflects the time taken for the depolarization and contraction of the ventricles.
