Difficulty: MediumReduction of Risk Potential

A postoperative client on the surgical unit suddenly develops acute shortness of breath and pleuritic chest discomfort 36 hours after bariatric surgery. Clinical assessment reveals tachypnea at 32 breaths per minute, tachycardia at 115 beats per minute, and an oxygen saturation of 87%87\% on room air. Arterial blood gas analysis displays a pH of 7.547.54, a PaCO2PaCO_2 of 29 mm Hg29\text{ mm Hg}, a PaO2PaO_2 of 55 mm Hg55\text{ mm Hg}, and an HCO3−HCO_3^- of 22 mEq/L22\text{ mEq/L}. Based on these findings, what is the priority nursing intervention to mitigate the risk of further physiological decline?

  1. A
    Administer the prescribed as-needed intravenous morphine sulfate to relieve the chest discomfort
  2. B
    Coach the client to take slow, deep breaths into a paper bag to resolve the acid-base imbalance
  3. Initiate supplemental oxygen therapy and immediately activate the rapid response teamAnswer
  4. D
    Lower the head of the bed to a flat position to optimize venous return and cardiac output

Answer

Initiate supplemental oxygen therapy and immediately activate the rapid response team.
The client's clinical presentation and arterial blood gas results indicate severe hypoxemia causing compensatory hyperventilation (respiratory alkalosis). This constellation of findings in a postoperative client is highly suspicious for a pulmonary embolism. Applying the Airway-Breathing-Circulation prioritization framework, the immediate priority is to correct the life-threatening oxygen deficit and escalate care to prevent cardiopulmonary collapse.

Step-by-Step Solution

1
Analyze the client's vital signs and clinical presentation.
The client presents with sudden dyspnea, pleuritic chest pain, tachycardia, and significant hypoxia, which are highly suspicious for an acute pulmonary embolism.
Identifying the underlying clinical emergency dictates the immediate priority of nursing care.
2
Interpret the arterial blood gas (ABG) values.
The ABG reveals uncompensated respiratory alkalosis (pH 7.54, PaCO2 29 mm Hg) driven by severe hypoxemia (PaO2 55 mm Hg).
Understanding the primary cause of the acid-base imbalance ensures interventions target the root physiological problem rather than just secondary symptoms.
3
Determine the priority intervention based on the Airway-Breathing-Circulation (ABC) framework.
Providing immediate supplemental oxygen and escalating care via the rapid response team is required.
Severe hypoxemia is the most immediate threat to the client's life and must be addressed prior to managing secondary issues like pain or anxiety.
