Damage to the SA node can result in a slower heart rate (bradycardia) and decreased cardiac output. Therefore, the nurse should assess the client for these potential complications. The client is less likely to experience an increased heart rate (tachycardia) or increased cardiac output due to damage to the SA node. The strength of ventricular contractions would be more affected by damage to the ventricles themselves rather than the SA node.
