A nurse is caring for a client who recently had surgery for the insertion of a permanent pacemaker. Which of the following prescriptions should the nurse clarify?

Choice A reason: Defibrillation is used in the case of life-threatening cardiac rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia. It is not the first line of treatment for a stable patient with VT.

Choice B reason: CPR is initiated when a patient is unresponsive and not breathing or not breathing normally, indicating cardiac arrest. It is not indicated for a patient who is stable and experiencing VT.

Choice C reason: Elective cardioversion is a procedure where an electrical shock is delivered to the heart to convert an abnormal rhythm back to a normal sinus rhythm. It is typically used for rhythms such as atrial fibrillation or atrial flutter, not first line for VT.

Choice D reason: Radiofrequency catheter ablation is a procedure that uses radiofrequency energy to destroy a small area of heart tissue that is causing rapid and irregular heartbeats. In the case of VT, this procedure is used to target the area causing the abnormal rhythm and is a common treatment for recurrent VT.

The correct answer is: c. Prepare the client for intubation.

Choice A: Prepare to administer a vasopressor

Reason: Vasopressors are typically used to manage hypotension (low blood pressure) and are not a standard treatment for myasthenic crisis. Myasthenic crisis primarily involves respiratory muscle weakness, which can lead to respiratory failure, rather than issues with blood pressure.

Choice B: Administer an anticholinesterase medication

Reason: While anticholinesterase medications like pyridostigmine are used to manage myasthenia gravis, they are generally not recommended during a myasthenic crisis. During a crisis, the focus is on stabilizing the patient, often requiring more immediate interventions such as intubation and mechanical ventilation.

Choice C: Prepare the client for intubation

Reason: Intubation is a critical intervention in a myasthenic crisis due to the risk of respiratory failure. The crisis is characterized by severe muscle weakness, including the muscles that control breathing. Intubation ensures that the airway is protected and that the patient can receive adequate ventilation.

Choice D: Instruct the client to perform pursed lip breathing

Reason: Pursed lip breathing is a technique used to improve breathing efficiency in conditions like chronic obstructive pulmonary disease (COPD). However, it is not appropriate for managing a myasthenic crisis, where the primary issue is severe muscle weakness leading to respiratory failure.
