A nurse is assisting with the care of a client. Select the 3 findings that require immediate follow-up.

A. Pedal pulses: Bilateral pedal pulses are documented as 2+, indicating adequate peripheral perfusion. There is no change from baseline findings on day 1. This assessment does not suggest acute circulatory compromise requiring urgent intervention. B. Respiratory rate: An increase in respiratory rate to 24/min indicates tachypnea, which may reflect pain, infection, hypovolemia, or evolving sepsis. In the postoperative setting, this change represents physiologic stress and warrants prompt assessment. It may also signal compensation for metabolic acidosis or hypoxia. C. Breath sounds: Breath sounds remain clear and present throughout, consistent with earlier findings. There is no evidence of atelectasis, pneumonia, or fluid overload based on this assessment. This finding does not indicate an acute deterioration. D. Oxygen saturation: Oxygen saturation remains stable at 95% on room air, which is adequate for this client. There is no significant decline from baseline values. This parameter alone does not indicate immediate respiratory compromise. E. Abdominal dressing: A large amount of serosanguinous drainage following a sensation of something “popping” raises concern for wound dehiscence. This is a surgical emergency that can rapidly progress to evisceration. Immediate assessment and intervention are required to prevent further complications. F. Heart rate: A heart rate of 110/min represents tachycardia and is a significant change from baseline. This may indicate hypovolemia from blood loss, infection, or systemic inflammatory response. In combination with hypotension and fever, this finding suggests potential sepsis or hemorrhage and requires urgent follow-up.
