BON EXAM QUESTIONS WITH A 100 % CORRECT
ANSWERS 2024
NSR (Normal Sinus Rhythm) - ✔✔• Rate: Between 60-99/minute
• Rhythm: Regular, originates in the sinus node
• P-QRS-T
NSR (Normal Sinus Rhythm) - ✔✔
Bradycardia - ✔✔• Sinus rhythm with a rate less than 60
• Only requires treatment if symptomatic
• Determine the underlying cause
Bradycardia - ✔✔
Tachycardia - ✔✔• Sinus rhythm with a rate greater than 99, but less than
160
• Determine and treat the underlying cause. Generally occurs due to need
for more cardiac output
Tachycardia - ✔✔
, Sinus Arrhythmia - ✔✔• Rhythm that originates in the sinus node, but is
irregular, may be due to respirations
Sinus Arrhythmia - ✔✔
Sinus Exit Block - ✔✔• Occurs when the impulse is produced by the sinus
node, but is blocked. When the "block" is over, rhythm picks up in previous
pattern (the P-P pattern maps out)
• The length of the pause is calculated by the number of small boxes
between QRS complexes multiplied by 0.04 seconds
Sinus Exit Block - ✔✔
Sinus Arrest/Pause - ✔✔• Occurs when the sinus node does not generate
an impulse, so the p-p pattern does not map out through the pause.
• The length of the pause is calculated by the number of small boxes
between QRS complexes multiplied by 0.04 seconds
Sinus Arrest/Pause - ✔✔
Premature Atrial Contraction (PAC) - ✔✔• An early beat from irritable atrial
tissue
• If the P can be seen, it differs from sinus P waves. P is often buried in
previous T wave
