Final answer:
Among the options provided, mild restlessness is a potential sign of shock and should be reported to the healthcare provider. While the other options may not be direct indicators of shock, it's essential for healthcare professionals to watch for a variety of signs to detect and manage shock early.
Step-by-step explanation:
A nurse is caring for a client who is 1 hour postoperative following an aortic aneurysm repair, and the nurse needs to be vigilant for signs of shock. Among the choices provided, mild restlessness could indicate the onset of shock and should be reported. Restlessness could be an early sign of hypoperfusion and inadequate oxygen delivery to the brain. Although a blood pressure of 140/90 mm Hg is elevated, it does not indicate shock in this context. A urine output of 50 mL/hr is within normal range immediately postoperative, as typically urine output less than 1 mL/kg body weight/hour is concerning. A decreased respiratory rate can be a sign of shock, but it may also indicate other postoperative issues such as effects from anesthesia or pain management, hence it may not be as specific an indicator as restlessness. Overall, it is crucial for the nurse to monitor for multiple symptoms of shock, including changes in mental status, as well as vital sign abnormalities. This vigilance is key to early detection and treatment, which may include fluid replacement and medications to restore proper circulatory function.
