Which of the following occurrences does a nurse have to observe for, in vagal nerve stimulation while removing fecal impaction?

Correct option is D

During removal of fecal impaction, vagal nerve stimulation may occur due to rectal manipulation, triggering a parasympathetic response. This can lead to bradycardia (a slowed heart rate), which is a potentially dangerous complication. Nurses must monitor the patient’s pulse and stop the procedure if signs of bradycardia appear. Prompt detection and intervention can prevent serious cardiac consequences.
Explanation of options: (a) Tachycardia – Tachycardia refers to an increased heart rate, which is more typical of a sympathetic nervous system response, not vagal stimulation. Hence, this is not expected during fecal disimpaction involving the vagus nerve. (b) Pain – Although discomfort or pain may occur during the procedure, it is not the key clinical sign of vagal stimulation. It doesn't serve as a critical warning for vagal-induced complications like bradycardia. (c) Elevated body temperature – This may indicate infection or inflammation but is unrelated to vagal stimulation during fecal impaction. It is not an acute concern during the actual procedure. (d) Bradycardia – This is the correct answer. Vagal stimulation activates the parasympathetic nervous system, which slows the heart rate. Monitoring for bradycardia is essential during procedures like digital rectal stimulation.
