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
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 D
Explanation
D. Asystole represents the absence of electrical activity in the heart and is not amenable to defibrillation. Therefore, the RRT would continue cardiopulmonary resuscitation (CPR) with chest compressions and may administer medications or other interventions as indicated. This statement provides accurate information to the family about the patient's condition and the actions being taken by the RRT.
A. Defibrillation is not indicated for asystole. Asystole represents a flatline on the cardiac monitor, indicating the absence of electrical activity in the heart. Defibrillation is only effective for certain types of cardiac rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia. Therefore, the RRT would not use defibrillation for a patient in asystole.
B. It does not provide the family with information about the patient's condition or the actions being taken by the RRT. Moreover, excluding the family from the patient's care may cause additional distress and prevent them from being present to support their loved one during a critical situation.
C. Cardiopulmonary resuscitation (CPR) is performed to maintain blood flow and oxygenation to vital organs during cardiac arrest. However, it does not restore normal blood flow or circulation. The goal of CPR is to provide temporary support until advanced interventions can be initiated or until return of spontaneous circulation (ROSC) is achieved.
Correct Answer is D
Explanation
D. A pulmonary artery catheter is used to monitor hemodynamic status. It provides valuable information about cardiac function, preload, afterload, and cardiac output. By measuring parameters such as pulmonary artery pressure, pulmonary artery wedge pressure, and central venous pressure, a pulmonary artery catheter helps assess the effectiveness of cardiac function and guide management in critically ill patients, especially those with conditions such as heart failure, shock, or pulmonary hypertension.
A. A pulmonary artery catheter, also known as a Swan-Ganz catheter, is not used to monitor intracranial pressure. Instead, it is primarily used to assess hemodynamic status and cardiac function by measuring parameters such as pulmonary artery pressure, pulmonary artery wedge pressure, central venous pressure, and cardiac output.
B. A pulmonary artery catheter is not used to directly monitor renal function. While changes in hemodynamic status can impact renal perfusion and function, the primary purpose of a pulmonary artery catheter is to assess cardiac function and hemodynamics, rather than renal function.
C. A pulmonary artery catheter is not used to monitor spinal cord perfusion. Although alterations in hemodynamic status can affect spinal cord perfusion indirectly, the main purpose of a pulmonary artery catheter is to evaluate cardiac function and hemodynamics.
