What finding would cause the nurse to terminate an activity for a patient 36 hours post CABG?

The respiratory rate of 28 breaths per minute is a significant finding that would lead a nurse to consider terminating an activity for a patient who is 36 hours post-coronary artery bypass graft (CABG). A respiratory rate that is elevated, especially above 20 breaths per minute, may indicate respiratory distress, agitation, or inadequate ventilation. Patients following CABG are at risk for various complications, including impaired gas exchange, atelectasis, and respiratory infections. Monitoring respiratory status closely is crucial, and an elevated respiratory rate can signal the need for intervention, further assessment, or an adjustment in activity level to ensure patient safety.

In contrast, a pulse rate of 60 and regular is within an acceptable range for a post-operative patient, as bradycardia may not pose an immediate concern if the patient is stable and asymptomatic. Urinary frequency may simply indicate increased fluid intake or may not be significant in the immediate post-operative period. Incisional discomfort is a common experience after surgery and, while it should be monitored and managed, it does not necessarily warrant terminating activity unless it is extreme or accompanied by other concerning symptoms. Thus, the respiratory rate is a critical parameter that directly affects the patient's overall stability and warrants immediate attention.
