Describe strategies for safe, effective multidimensional nursing care for clients with acid-base imbalances.
Scenario
Tony is a 56-year-old, Hispanic male that presented to the Emergency Room with complaints of shortness of breath, which he has been experiencing for the past two days. He states “I haven’t felt good for about a week, but couldn’t afford to miss work.” He complains of a cough, fever, and feeling exhausted. Past medical history includes asthma, chronic obstructive pulmonary disease and diabetes. Upon physical examination, you notice that Tony is struggling to breathe, his respiratory rate is 36 breaths per minute and labored, heart rate 115 beats per minute, blood pressure 90/40 mm Hg, and his pulse oximetry is 84% on room air. You notify the MD. He orders oxygen at 2 L via NC and an arterial blood gas.
Tony’s ABG results:
pH 7.28
PaCO2 – 55 mm Hg
PaO2 – 70 mm Hg
HCO3 – 30 mEq/L

Multidimensional Nursing Care Strategies for Clients with Acid-Base Imbalances
Acid-Base Imbalance Determination
Based on Tony's arterial blood gas (ABG) results:
- pH: 7.28 (normal range: 7.35 - 7.45)
- PaCO2: 55 mm Hg (normal range: 35 - 45 mm Hg)
- PaO2: 70 mm Hg (normal range: 80 - 100 mm Hg)
- HCO3: 30 mEq/L (normal range: 22 - 28 mEq/L)
Tony’s low pH indicates acidemia, and his elevated PaCO2 suggests respiratory acidosis. The HCO3 is slightly elevated, indicating a possible compensatory mechanism. Therefore, Tony is experiencing acute respiratory acidosis.
Possible Causes of the Imbalance
The primary cause of Tony's respiratory acidosis is likely due to his underlying respiratory conditions, particularly:
1. Chronic Obstructive Pulmonary Disease (COPD): This condition can lead to difficulty in exhaling carbon dioxide, resulting in its accumulation in the bloodstream.
2. Asthma exacerbation: Increased airway resistance can lead to inadequate ventilation and CO2 retention.
3. Infection: Tony's fever and cough suggest a potential respiratory infection, which can increase the work of breathing and worsen his underlying lung conditions.
4. Hypoventilation: His labored breathing and increased respiratory rate indicate that he may not be effectively ventilating, contributing to CO2 retention.
Signs and Symptoms Exhibited by Tony
Tony is exhibiting several signs and symptoms related to his acid-base imbalance, including:
- Shortness of Breath: Difficulty breathing is a direct symptom of respiratory distress.
- Increased Respiratory Rate: His respiratory rate of 36 breaths per minute indicates tachypnea as a compensatory mechanism.
- Labored Breathing: Indicates increased work of breathing and potential airway obstruction.
- Tachycardia: A heart rate of 115 beats per minute may be a response to hypoxia and acidosis.
- Hypotension: Blood pressure of 90/40 mm Hg indicates possible shock or inadequate perfusion.
- Hypoxemia: A pulse oximetry reading of 84% indicates significant oxygen deprivation, which can exacerbate acidosis.
Multidimensional Nursing Care Strategies
To provide safe and effective multidimensional nursing care for Tony, the following strategies should be implemented:
1. Respiratory Support
- Administer supplemental oxygen as ordered (starting at 2 L via nasal cannula) and monitor oxygen saturation levels regularly.
- Consider bronchodilator therapy if indicated, such as albuterol, to relieve bronchospasm and improve airflow.
- Assess the need for further respiratory support, such as non-invasive ventilation (e.g., BiPAP) if his condition does not improve.
2. Monitoring and Assessment
- Continuously monitor vital signs, including heart rate, respiratory rate, blood pressure, and oxygen saturation.
- Regularly assess lung sounds for changes (e.g., wheezing or dullness) and signs of respiratory distress.
- Obtain repeat ABGs as necessary to evaluate the effectiveness of interventions.
3. Fluid Management
- Administer IV fluids as ordered to address potential hypotension and improve perfusion status.
- Monitor intake and output to assess fluid balance and kidney function.
4. Medications
- Administer prescribed medications promptly, including bronchodilators, corticosteroids (to reduce inflammation if indicated), and antibiotics if an infection is suspected.
- Monitor for potential side effects of medications and adjust doses as needed based on clinical response.
5. Education and Support
- Educate Tony on the importance of medication adherence, including inhalers and any prescribed treatments for his underlying conditions.
- Discuss lifestyle modifications, such as smoking cessation if applicable, and the importance of regular follow-up visits with a healthcare provider.
6. Collaboration with Healthcare Team
- Communicate findings to the healthcare team, including physicians and respiratory therapists, to ensure comprehensive care.
- Involve case management or social work if financial concerns regarding treatment arise, as Tony expressed difficulty affording time off work.
Conclusion
Addressing Tony's acute respiratory acidosis requires a multidimensional approach that includes respiratory support, careful monitoring, medication management, education, and collaboration with the healthcare team. Implementing these strategies will help stabilize his condition while addressing the underlying causes of the acid-base imbalance.
