When the nurse observes that the patient’s heart rate increases
during inspiration and decreases during expiration, the nurse
reports that the patient is demonstrating
a) sinus dysrhythmia.
Sinus dysrhythmia occurs when the sinus node creates an impulse at
an irregular rhythm.
b) normal sinus rhythm.
Normal sinus rhythm occurs when the electrical impulse starts at a
regular rate and rhythm in the SA node and travels through the
normal conduction pathway.
c) sinus bradycardia.
Sinus bradycardia occurs when the sinus node regularly creates an
impulse at a slower-than-normal rate.
d) sinus tachycardia.
Sinus tachycardia occurs when the sinus node regularly creates an
impulse at a faster-than-normal rate.
