A nurse is caring for a client who has pericarditis and reports feeling a new onset of palpitations and shortness of breath. Which of the following assessments should indicate to the nurse that the client may have developed atrial fibrillation?

Different blood pressures in the upper limbs.

Differences in upper and lower lung sounds.

Differences between oral and axillary temperatures.

Different apical and radial pulses.

Answer and Explanation

The Correct Answer is D

D. Atrial fibrillation can lead to irregular and often rapid heart rates, resulting in discrepancies between the apical (heart) and radial (peripheral) pulses. In atrial fibrillation, the atria fibrillate instead of contracting effectively, leading to irregular and sometimes asynchronous ventricular contractions. This irregularity may result in a pulse deficit, where the number of apical beats exceeds the number of radial pulses felt at the wrist.

A. Different blood pressures in the upper limbs may indicate conditions such as aortic dissection or arterial stenosis, but they are not typically associated with atrial fibrillation. Atrial fibrillation primarily affects the heart rhythm rather than blood pressure distribution.

B. Differences in upper and lower lung sounds may indicate conditions such as pneumonia or pleural effusion, but they are not specific to atrial fibrillation. Atrial fibrillation primarily affects the heart's electrical activity rather than respiratory findings.

C. Differences between oral and axillary temperatures may indicate localized variations in temperature, such as infection or inflammation, but they are not specific to atrial fibrillation. Atrial fibrillation primarily affects cardiac rhythm rather than body temperature regulation.

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. Initiation of continuous positive pressure ventilation (CPAP) B. Endotracheal intubation and positive pressure ventilation C. Insertion of a mini-tracheostomy with frequent suctioning D. Administration of 100% O2 by non-rebreather mask

Correct Answer is B

Explanation

B. Endotracheal intubation and positive pressure ventilation are indicated in patients with respiratory failure who are unable to maintain adequate oxygenation or ventilation with non-invasive interventions. Intubation allows for the delivery of positive pressure ventilation, oxygenation, and airway protection. It also facilitates the clearance of secretions and administration of medications. Given the patient's severe hypoxemia, impending respiratory distress, and deteriorating condition, endotracheal intubation and positive pressure ventilation are the most appropriate interventions to ensure adequate oxygenation and prevent further deterioration.

A. CPAP is a non-invasive ventilation modality that provides a continuous positive pressure to the airways throughout the respiratory cycle. While CPAP may be beneficial in certain cases of respiratory failure, it may not be sufficient for a patient with severe hypoxemia (SpO2 of 80%) and impending respiratory distress. CPAP is typically indicated for patients with conditions such as obstructive sleep apnea or mild to moderate respiratory failure.

C. Mini-tracheostomy may be considered in certain cases of upper airway obstruction or inadequate airway clearance. However, in this scenario, the patient's hypoxemia is likely due to severe respiratory failure rather than upper airway obstruction. While suctioning may be necessary to clear secretions, it does not address the underlying cause of hypoxemia or provide ventilatory support.

D. While administration of supplemental oxygen is important in the management of hypoxemia, a non- rebreather mask may not be sufficient for a patient with severe hypoxemia and impending respiratory distress. Non-rebreather masks can deliver high concentrations of oxygen but may not provide adequate positive pressure support or airway protection. In this case, endotracheal intubation and positive pressure ventilation are more appropriate to ensure adequate oxygenation and ventilation.
