For a patient with supraventricular tachycardia undergoing cardioversion, what should the respiratory therapist prepare?

• A. Create a preparation of Atropine
• B. Prepare a bag-valve-mask
• C. Obtain an arterial blood gas
• D. Check for adequate sedation

Answer: (B)

In the context of a patient with supraventricular tachycardia (SVT) undergoing cardioversion, preparing a bag-valve-mask (BVM) is crucial to ensure adequate ventilation and oxygenation during the procedure. Cardioversion often requires sedation, and if the patient experiences respiratory depression or any difficulty in breathing, having a BVM ready affords the therapist the ability to assist with ventilation promptly.

The patient may also be unconscious or unable to maintain their airway during the procedure, thus necessitating the need for passive ventilation support. This preparation helps maintain the patient's respiratory function and ensures safety during the cardioversion.

While sedation and monitoring such as arterial blood gas could be important, the immediate need to prepare for potential airway management highlights the necessity of having a BVM on hand. This way, the respiratory therapist is well-equipped to respond to any respiratory complications that may arise during the procedure.
