Regarding a client who has recently undergone surgery, what observation could indicate complications?

The development of shortness of breath and agitation is a significant observation that could indicate complications following surgery. These symptoms can be associated with several critical issues, such as respiratory distress, the onset of a pulmonary embolism, or an adverse reaction to anesthesia. Shortness of breath can suggest that the patient is experiencing inadequate oxygenation or potential cardiovascular problems, while agitation may indicate anxiety, pain, or a severe response to a medical situation. In the context of post-surgical care, these symptoms require immediate evaluation and intervention to prevent further deterioration of the patient's condition.

On the other hand, feeling pain within manageable limits often reflects a normal post-operative experience as patients may expect some degree of discomfort during recovery. Symptoms of fatigue and mild discomfort are also common as the body heals; these, too, generally do not indicate significant complications. Minor variations in blood pressure readings may occur due to various factors, such as anxiety, medication effects, or natural fluctuations in bodily functions, and are not always indicative of a severe issue unless they fall outside the typical parameters for that patient.
