A nurse is caring for a 72-year-old patient with chronic obstructive pulmonary disease (COPD) who was admitted with acute exacerbation. The patient presents with increased dyspnea, productive cough with thick yellow sputum, and oxygen saturation of 88% on room air. The patient is receiving oxygen therapy at 2 L/min via nasal cannula and has been started on corticosteroids and bronchodilators. Which nursing action should be the highest priority for this patient?

Monitoring respiratory status and ABG levels is the priority to guide safe interventions in COPD patients, as they are at risk for CO2 retention and altered respiratory drive. Other actions like bronchodilator administration or oxygen adjustment require assessment data first.

Clinical Context & Priority Setting Framework

This scenario describes a 72-year-old patient with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The patient exhibits hallmark signs: increased dyspnea, a productive cough with purulent sputum, and significant hypoxemia evidenced by an oxygen saturation of 88% on room air. While the patient is already receiving low-flow oxygen, corticosteroids, and bronchodilators, the question asks for the highest priority nursing action. In NCLEX-RN prioritization, the nursing process dictates that assessment always comes before implementation, provided the patient is not in a life-threatening crisis requiring immediate intervention. Here, the patient’s condition is unstable but being managed; therefore, the crucial next step is a thorough, ongoing assessment to evaluate the effectiveness of current therapies and detect any deterioration.

Rationale for the Correct Answer (Option 4)

The correct action is to monitor respiratory status and blood gas levels closely. An AECOPD is defined as a sustained worsening of the patient's respiratory symptoms that goes beyond normal day-to-day variations and necessitates a change in management ^[2]. The patient’s baseline in COPD involves some degree of chronic symptom fluctuation, but an exacerbation represents a distinct, acute decline ^[2]. Because the trajectory of an exacerbation can be unpredictable and is a major driver of poor outcomes, including hospitalization and mortality, the nurse’s primary responsibility is vigilant surveillance ^[1].

Monitoring provides the data needed to determine if the current interventions (oxygen at 2 L/min, steroids, bronchodilators) are reversing the hypoxemia and reducing the work of breathing. A key concern during an AECOPD is the potential for comorbid cardiac decompensation, which is often undiagnosed and carries a high risk of acute cardiac events ^[3]. By closely tracking respiratory status—including rate, depth, breath sounds, accessory muscle use, and continuous pulse oximetry—alongside arterial blood gas (ABG) results, the nurse can identify early signs of clinical deterioration, such as rising CO2 levels or impending respiratory failure. This assessment data is essential for the healthcare team to make timely, informed decisions about escalating or altering therapy.

Why the Other Options Are Lower Priority

- Option 1: Administering a prescribed albuterol nebulizer treatment is an implementation task. While it is an important part of the treatment plan, it should not take priority over a focused assessment. The nurse must first evaluate the patient’s current respiratory status and breath sounds to have a baseline for determining the treatment’s effectiveness. Performing an intervention before a complete assessment is a violation of the nursing process.
- Option 2: Increasing the oxygen flow rate to 4 L/min without a specific order is outside the nurse’s scope of practice and can be dangerous in a COPD patient. The patient’s respiratory drive may be dependent on a hypoxic stimulus, and uncontrolled oxygen administration can lead to oxygen-induced hypercapnia and respiratory depression. Any change in oxygen delivery requires a provider’s order based on a clinical assessment, which again underscores the priority of monitoring.
- Option 3: Encouraging deep breathing and coughing exercises is a beneficial intervention for airway clearance, especially given the thick sputum. However, this is a lower-priority, non-acute intervention. In a patient with acute dyspnea and significant hypoxemia, the immediate focus must be on assessing the severity of the exacerbation and the response to pharmacological and oxygen therapy, not on coaching exercises that may increase fatigue and oxygen consumption in the acute phase.
