The nurse is caring for an older adult patient who is displaying alterations in the conduction of impulses in the SA node which the nurse assesses as what?
A) Cardiac gallop
B) Tachycardia
C) Cardiac dysrhythmias
D) Heart murmurs
C
Feedback:
Alterations in the generation of conduction of impulses in the heart cause arrhythmias (dysrhythmias), which can upset the normal balance in the cardiovascular system and lead to a decrease in cardiac output, affecting all of the cells of the body. Tachycardia is only one of the possible arrhythmias that may result. Cardiac gallop and murmurs in the older adult with no history of congenital anomalies is usually caused by a poorly functioning heart valve and not by an alteration in conduction.
