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. 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.

A. Provide 02 at 100% per non-rebreather mask. B. Initiate continuous electrocardiogram (ECG) monitoring C. Draw blood to type and crossmatch for transfusions. D. Insert two large-bore IV catheters.

Correct Answer is A

Explanation

A The first intervention should be to ensure adequate oxygenation, as hypoxia can exacerbate shock. Therefore, providing oxygen at 100% via a non-rebreather mask is the most critical initial step. This intervention helps to maximize the amount of oxygen delivered to the patient's lungs and subsequently to the rest of the body, supporting vital organ function while further assessments and interventions are prepared.

B Continuous ECG monitoring allows for the assessment of the patient's heart rhythm, rate, and any signs of dysrhythmias or cardiac ischemia. This intervention is important for detecting any life- threatening arrhythmias, such as ventricular tachycardia or fibrillation, which may require immediate intervention. While ECG monitoring is important, it may not be the highest priority intervention.

C Drawing blood for type and crossmatch is important for preparing for potential blood transfusions if significant blood loss is suspected. However, this intervention may take some time to process, and immediate stabilization of the patient's condition is paramount.

D Large-bore IV catheters allow for rapid infusion of fluids to restore intravascular volume and improve tissue perfusion. This intervention is critical for stabilizing the patient's hemodynamic status and takes precedence in the management of shock. However, oxygenation should take priority.
