The nurse is educating a patient who is newly diagnosed with amyotrophic lateral sclerosis (ALS). Which statement would be the most appropriate for the nurse to include in education?

Unstable Supraventricular Tachycardia: Synchronized Cardioversion

Unstable Bradycardia: Transcutaneous Pacing

Ventricular Fibrillation: Defibrillation

Ventricular Tachycardia with No Pulse: Defibrillation

Unstable Atrial Flutter: Synchronized Cardioversion

Rationales:

Unstable Supraventricular Tachycardia – Synchronized Cardioversion:

Synchronized cardioversion delivers a timed electrical shock to the heart during the R wave, avoiding the vulnerable T wave, which minimizes the risk of inducing ventricular fibrillation. This intervention is preferred for unstable SVT unresponsive to medications, as it restores normal sinus rhythm effectively.

Unstable Bradycardia – Transcutaneous Pacing:

Transcutaneous pacing provides electrical impulses to stimulate the heart when intrinsic conduction is insufficient. It is the recommended treatment for symptomatic bradycardia that does not respond to medications, ensuring adequate cardiac output while awaiting more definitive treatment.

Ventricular Fibrillation – Defibrillation:

Defibrillation delivers an unsynchronized shock to depolarize the entire myocardium, allowing the heart to reset and resume an organized rhythm. It is the first-line intervention for ventricular fibrillation, as the chaotic electrical activity makes the heart incapable of pumping blood.

Ventricular Tachycardia with No Pulse – Defibrillation:

Pulseless ventricular tachycardia requires defibrillation, as the rhythm is life-threatening and the absence of a pulse indicates the heart is not effectively pumping. This unsynchronized shock interrupts the abnormal rhythm, allowing normal sinus rhythm to potentially resume.

Unstable Atrial Flutter – Synchronized Cardioversion:

Synchronized cardioversion is used for unstable atrial flutter to restore sinus rhythm by delivering a precisely timed electrical shock. It is effective when pharmacological measures have not worked or are inappropriate, especially in cases of hemodynamic instability.

A) Respiratory rate of 8 bpm:
This a sign of respiratory depression, which can occur in patients with chronic obstructive pulmonary disease (COPD) who are receiving high-flow oxygen. In COPD patients, particularly those with chronic hypercapnia (elevated carbon dioxide), the body may become less sensitive to CO2 buildup and more reliant on low oxygen levels to trigger the respiratory drive. If oxygen is administered at high flow rate, it can reduce the stimulus for breathing, leading to hypoventilation or even respiratory arrest.

B) A large barrel chest:
A barrel chest is a common physical finding in patients with chronic COPD due to the hyperinflation of the lungs. This is a result of air trapping, which is a hallmark of COPD. While it indicates the long-term effects of COPD, it does not require immediate intervention. It is a chronic sign and not an acute or urgent concern unless accompanied by other signs of acute respiratory distress.

C) Fine crackles:
Fine crackles (or rales) on auscultation can be indicative of fluid in the lungs and may suggest conditions such as pulmonary edema, heart failure, or pneumonia. While crackles could be concerning, they are not as immediately life-threatening as a respiratory rate of 8 bpm. In a patient with COPD, crackles might indicate worsening of their condition, possibly due to an infection or fluid overload, but the priority would still be to assess the patient's breathing and ventilation status first.

D) The patient assumes the orthopneic position:
The orthopneic position (sitting upright or leaning forward) is a common way for patients with COPD to relieve shortness of breath. It is a compensatory action to help improve lung expansion and facilitate breathing. While it is a sign of respiratory distress, it is not an immediate emergency. Many COPD patients use this position to cope with chronic difficulty breathing.
