A nurse is caring client who has peptic ulcer disease and is scheduled to undergo an esophagogastroduodenoscopy. Which of the following actions should the nurse take prior to the procedure?

A. Temperature: The client’s temperature increased from 37.2°C (99°F) to 38.9°C (102°F), indicating a possible infection or systemic inflammatory response. Fever in acute pancreatitis can suggest worsening inflammation, infection, or sepsis and should be reported immediately.
B. Blood pressure: The client's blood pressure dropped from 126/78 mmHg to 92/48 mmHg, indicating hypotension, which could be due to fluid shifts, systemic inflammation, or early shock. Immediate intervention is necessary to prevent hemodynamic instability.
C. Pain: While severe pain (rated 10/10) is expected in acute pancreatitis, it is not the most urgent concern requiring immediate reporting compared to hemodynamic instability and respiratory distress.
D. Urine output: The current urine output is not critically low (50-60 mL/hr), but continued monitoring is necessary. However, it is not an immediate life-threatening concern requiring urgent reporting.
E. Heart rate: The client’s heart rate increased from 90/min to 132/min, which is a significant tachycardia. This suggests compensatory shock, fluid loss, or worsening systemic inflammation and requires immediate provider notification.
F. Respiratory status: The respiratory rate increased from 18/min to 32/min, and oxygen saturation dropped to 88% on 3 L/min O₂. This suggests respiratory compromise, possibly due to worsening systemic inflammation, pleural effusion, or acute respiratory distress syndrome (ARDS).
G. Sodium level: The sodium level remains within the normal range (142 mEq/L; normal: 136-145 mEq/L), so it does not require immediate reporting.
H. Mental confusion: The client, who was alert on Day 1, is now disoriented. This change in mental status can indicate worsening systemic inflammation, hypoxia, or impending shock, requiring urgent intervention.
I. Serum amylase level: While elevated (498 units/L), this is expected in pancreatitis and does not require immediate notification unless there is a sudden drastic change.
J. Cold, clammy skin: This is a sign of poor perfusion and possible shock. It indicates worsening hemodynamic instability and requires immediate intervention.

A) Check the client's pulse rate: While it is important to assess vital signs, the priority in this scenario is ensuring that the client’s airway is open and that they can breathe adequately. A pulse rate check can be performed after addressing the immediate respiratory needs.

B) Administer oxygen to the client: Administering oxygen is important for clients who are cyanotic and showing signs of respiratory distress. However, oxygen will not be effective if the airway is obstructed. The first priority is to ensure that the airway is open and clear, as this is the most immediate need for breathing.

C) Establish a patent airway for the client: The most immediate priority is to ensure that the client has a patent airway. Cyanosis and a decreased respiratory rate with shallow respirations indicate that the client is likely unable to get enough oxygen, possibly due to an obstruction or inadequate airway. Once the airway is secured, other interventions such as administering oxygen can follow.

D) Place a pulse oximeter on the client's finger: While measuring oxygen saturation is important, the priority action is to ensure that the client’s airway is open first. If the client is cyanotic and showing signs of respiratory distress, the nurse must address the airway immediately before assessing the pulse oximeter reading, as it may not provide accurate data without a patent airway.
