NCLEX Practice Question:
The healthcare provider is teaching a patient who has a diagnosis of Wolff-Parkinson-White syndrome how to manage an occasional occurrence of atrioventricular reentrant tachycardia (AVRT). Which of these maneuvers will the healthcare recommend?
Select all that apply.
1. Breath-holding for several seconds
2. Applying firm bilateral carotid pressure
3. Coughing vigorously
4. Bearing down (as if having a bowel movement)
5. Taking a brisk walk for a couple of blocks
HINTS:
1. The patient will be instructed to perform maneuvers that stimulate the baroreceptors located in the aortic arch and carotid arteries.
2. Although massage of one carotid artery is sometimes used, bilateral carotid massage is contraindicated as it may cause the patient to faint.
3. Coughing, bearing down (Valsalva maneuver), and breath-holding are all vagal maneuvers which stimulate the Vagus nerve and can slow the conduction through the AV node and interfere with the circular loop of AVRT.
ANSWER: 1, 3, 4
