PRACTICE BANK MODULE QUESTIONS
SOLUTIONS ACCURACY REVIEW
RESOURCE COMPANION GRADED A+
⩥ The 6 Second Strip Method.
Answer: Least accurate, but quickest way to estimate rate especially in
irregular rhythms
⩥ EKG.
Answer:
⩥ EKG intervals.
Answer:
⩥ P Wave.
Answer: Atrial depolarization
⩥ PR Interval.
Answer: Normal is 0.12 to 0.20 seconds
Corresponds to the delay the AV node provides to allow for ventricular
filling
, ⩥ QRS Complex.
Answer: Normal is <0.12 seconds usually between 0.06 to 0.10 seconds
Ventricular depolarization
⩥ QT Interval.
Answer: Normal 0.36-0.46
⩥ 6 Steps for Rhythm Interpretation.
Answer: Determine Regularity
Calculate the Rate
Evaluate the P wave
Measure the PRI
Evaluate the QRS Width
Evaluate the T wave and Calculate the QTI
⩥ Normal Sinus Rhythm.
Answer: Regularity: atrial and ventricular rate are regular
Rate: 60 to 100 beats per minute
P wave: upright, smooth, round and uniform shape, one for every QRS
complex
PRI : 0.12 to 0.20 seconds
