Final answer:
After a pituitary surgery, the nurse's priority is to monitor the patient for hypovolemic shock, a potentially life-threatening condition that can follow surgery due to haemorrhage or inadequate fluid replacement.
Step-by-step explanation:
Prioritizing Post-Operative Monitoring
Following pituitary surgery, it is critical to monitor the patient for hypovolemic shock. This condition can be precipitated by haemorrhage and is characterized by symptoms such as a rapid, tachycardic heart rate, weak and thready pulse, cool clammy skin, rapid shallow breathing, hypothermia, thirst, and dry mouth. Immediate treatment typically involves administering intravenous fluids and may require medications such as dopamine, epinephrine, and norepinephrine to raise blood pressure and maintain adequate circulation. It is less likely, in the immediate postoperative period, for conditions such as congestive heart failure, infection, or volume overload to present as urgent concerns without pre-existing conditions suggesting these risks. Hypovolemic shock can occur from intraoperative or postoperative bleeding or inadequate fluid replacement, making it a priority for the nurse to monitor closely in the acute postoperative period following pituitary surgery.
