A patient with respiratory failure has a respiratory rate of 6 breaths/min and an oxygen saturation (SpO2) of 78%. The patient is increasingly lethargic. Which intervention will the nurse anticipate?

Initiation of continuous positive pressure ventilation (CPAP)

Endotracheal intubation and positive pressure ventilation

Insertion of a mini-tracheostomy with frequent suctioning

Administration of 100% 02 by non-rebreather mask

Answer and Explanation

The Correct Answer is B

B. Endotracheal intubation and positive pressure ventilation are indicated in patients with severe respiratory failure who are unable to maintain adequate oxygenation and ventilation on their own. This intervention provides mechanical support to the patient's breathing by delivering positive pressure to the lungs via an endotracheal tube. Given the patient's respiratory rate of 6 breaths/min, low oxygen saturation (SpO2 of 78%), and increasing lethargy, endotracheal intubation and positive pressure ventilation are the most appropriate interventions to ensure adequate oxygenation and ventilation.

A. CPAP is a form of non-invasive positive pressure ventilation that helps keep the airways open and improves oxygenation. However, in a patient with severe respiratory failure and impending respiratory arrest, CPAP alone may not be sufficient to adequately support ventilation and oxygenation. CPAP is typically used in patients with milder forms of respiratory failure or as a step-down therapy from invasive mechanical ventilation.

C. Insertion of a mini-tracheostomy is not typically indicated in a patient with severe respiratory failure and impending respiratory arrest. While tracheostomy may be considered in certain cases for long-term ventilation or airway management, it is not the first-line intervention in an acute situation like this.

Additionally, frequent suctioning may not address the underlying cause of respiratory failure or improve oxygenation.

D. Administering 100% oxygen via a non-rebreather mask can help improve oxygenation temporarily. However, in a patient with severe respiratory failure and impending respiratory arrest, non-invasive oxygen therapy alone may not be sufficient to maintain adequate oxygenation and ventilation.

Endotracheal intubation and positive pressure ventilation are more definitive interventions to ensure adequate support for the patient's breathing.

Correct Answer is B

Explanation

B Somnolence, or excessive sleepiness, can indicate respiratory depression, hypercapnia (elevated PaCO2), or impending respiratory failure. Somnolence in this context is concerning as it may suggest worsening respiratory status and impending respiratory compromise. Therefore, it should be immediately reported to the healthcare provider for further evaluation and intervention.

A blood pressure of 164/98 mmHg is elevated but may not necessarily require immediate intervention, especially if the patient is not exhibiting signs of acute hypertensive crisis or end-organ damage.

However, it should be closely monitored and managed as appropriate. While hypertension may contribute to respiratory distress, it may not be the most critical finding to report immediately in a patient with possible respiratory failure and a high PaCO2.

C An oxygen saturation of 90% indicates hypoxemia, which can exacerbate respiratory failure and contribute to respiratory distress. While hypoxemia requires prompt intervention to improve oxygenation, it may not be the most critical finding to report immediately if the patient is not showing signs of severe respiratory distress or impending respiratory failure. However, it should be closely monitored and managed to prevent further deterioration.

D Weakness is a nonspecific symptom and may be related to various underlying causes, including respiratory failure, electrolyte imbalances, or systemic illness. While weakness warrants further assessment and management, it may not be the most urgent finding to report immediately in a patient with possible respiratory failure and a high PaCO2 unless it is accompanied by other concerning symptoms or signs of impending respiratory compromise.

A. Respiratory rate 22 breaths/min B. Heart rate 106 beats/min C. 02 saturation of 99% D. Crackles audible at lung bases

Correct Answer is D

Explanation

D Crackles audible at the lung bases indicate the presence of pulmonary edema or fluid accumulation in the alveoli, which can compromise gas exchange and exacerbate respiratory distress. In a patient with ARDS, crackles suggest worsening pulmonary status and may indicate inadequate ventilation or oxygenation despite mechanical ventilation. Therefore, crackles at the lung bases are the most important finding to report to the healthcare provider as they may indicate a need for adjustments to the ventilator settings or additional interventions to optimize respiratory function and prevent further deterioration.

A respiratory rate of 22 breaths/min may be within an acceptable range, particularly considering that the patient is receiving mechanical ventilation. However, any significant deviation from the baseline respiratory rate or signs of respiratory distress, such as increased work of breathing or accessory muscle use, should be closely monitored and reported promptly.

B A heart rate of 106 beats/min may be within an acceptable range, although it is slightly elevated. Tachycardia can occur due to various factors, including pain, anxiety, fever, or hypoxemia. While tachycardia warrants close monitoring, it may not be the most critical finding to report unless it is associated with hemodynamic instability or other concerning symptoms.

C An oxygen saturation of 99% indicates adequate oxygenation, which is reassuring, particularly in a patient with acute respiratory distress syndrome (ARDS). However, oxygen saturation alone may not reflect the adequacy of ventilation or the severity of the underlying lung injury. Therefore, while oxygen saturation should be monitored closely, it may not be the most critical finding to report unless it declines significantly or is accompanied by other concerning symptoms.
