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 []

Explanation

AF is characterized by irregular, rapid heartbeat (100 to 175 beats per minute (bpm) and the absence of distinct P waves.

Management of unstable atrial fibrillation include immediate pharmacological or electrical cardioversion and anticoagulation.

Atrial fibrillation leads to ineffective pumping and stasis of blood in the heart which increases the risk of stroke.

On initiating anticoagulation, PTT/INR is important to ensure that the drug is administered at doses that achieve the optimal therapeutic effect.

A. Obtain a cardiology consult. B. Perform pre-oxygenation prior to suctioning. C. Suction the client less frequently. D. Administer an antidysrhythmic medication.

Correct Answer is B

Explanation

B. This is advised to prevent hypoxemia, which can manifest as tachycardia and arrhythmia, conditions indicated by an increased and irregular heart rate. Pre-oxygenation helps maintain adequate oxygen levels in the blood, which can be compromised during the suctioning process.

A. Obtaining a cardiology consult might be necessary if the client's heart rate increases and becomes irregular. However, it's not the immediate action the nurse should take. This option is more appropriate for addressing the underlying cause of the client's dysrhythmia rather than the immediate management during suctioning.

C. Suctioning the client less frequently might be appropriate if the client's response to suctioning is causing distress or physiological changes like increased heart rate. However, if suctioning is necessary due to secretions in the airway, simply reducing the frequency might not be sufficient to address the client's cardiovascular response.

D. Administering an antidysrhythmic medication should be considered if the client's heart rate increases and becomes irregular during or after suctioning, especially if the dysrhythmia persists or worsens.

However, this should be done under the guidance of a healthcare provider and after assessing the client's overall condition, including potential causes of the dysrhythmia.
