Question

A client in the cardiac step-down unit requires suctioning for excess mucous secretions. The nurse should be most careful to monitor the client for which dysrhythmia during this procedure? A. Bradycardia B. Tachycardia C. Premature ventricular beats D. Heart block

Short answer

Answer: Bradycardia

Step-by-step solution

Evaluating Option A - Bradycardia

Bradycardia is a slower-than-normal heart rate (less than 60 beats per minute). Suctioning may stimulate the vagus nerve, which can increase parasympathetic tone to the heart, thus causing bradycardia. Therefore, this dysrhythmia is a potential concern during suctioning.

Evaluating Option B - Tachycardia

Tachycardia refers to a faster-than-normal heart rate (more than 100 beats per minute). Although suctioning may cause some discomfort and anxiety for the client, it is generally not the primary cause of tachycardia during this procedure. So, this option is less likely to be the main concern.

Evaluating Option C - Premature Ventricular Beats

Premature ventricular beats are early heartbeats that originate in the lower chambers of the heart (ventricles). They may be induced by various factors, but suctioning procedure is not the primary cause. Therefore, this option is not the main concern.

Evaluating Option D - Heart Block

Heart block involves a delay or complete block in the electrical signals that control heartbeats. While it is a serious condition, it is not directly caused by suctioning. Therefore, this option is not the main concern.

Conclusion

After evaluating all the options, it is clear that the nurse should be most careful to monitor the client for bradycardia (Option A) during the suctioning procedure for excess mucous secretions. Bradycardia can be induced due to the stimulation of the vagus nerve during suctioning, making it the primary concern in this situation.
