Telemetry-Capstone Nursing Exam 54 Questions with Verified Answers Normal Sinus Rhythm - CORRECT ANSWER Heart Rate: 60-100 bpm Regularity: Regular PRI: .12-.20 seconds QRS: <.12 seconds Normal Sinus Bradycardia - CORRECT ANSWER Heart Rate: <60 bpm Regularity: Regular PRI: .12-.20 seconds QRS: <.12 seconds Normal Sinus Tachycardia - CORRECT ANSWER Heart Rate: >100 bpm Regularity: Regular PRI: .12-.20 seconds QRS: <.12 seconds Normal Sinus Arrhythmia - CORRECT A...

sinus bradycardia correct answer: -less than 60 beats per minute -P wave in front of every QRS -PR--0.12 to 0.20 -QRS less than 0.12 -if symptomatic--atropine, pacemaker sinus tachycardia correct answer: -treat underlying cause (fever, pain, etc.) Sinus Arrhythmia correct answer: irregular with breathing--HR increases with inspiration and decreases with expiration -only treat if hemodynamically compromised--atropine SA block correct answer: -dropped interval/pause -if hemodyna...

Know how to measure the PR interval ( PRI) - From where the P wave begins until the beginning of the QRS complex. 0.12 to 0.20 seconds (3 to 5 small boxes) in adults, longer in elderly people. Know how to measure the QRS - From the end of the PR interval to the end of the S wave. 0.08 to 0.10 seconds. (2-2 1/2 boxes) Know the normal values for the PRI and the QRS - PRI = 0.12 - 0.20 or 3-5 boxes QRS = 0.08 - 0.10 or 2- 2 1/2 boxes

Normal PRI interval - ANSWER 0.12-0.20 Normal QRS interval - ANSWER 0.11 or less What does the P wave represent? - ANSWER Atrial depolarization What does the QRS complex represent? - ANSWER Atrial repolarization and ventricular depolarization Q wave indicates what? - ANSWER Dead myocardial tissue. Always a negative deflection What is the natural pacemaker of the heart? - ANSWER SA node
