A nurse stops administering an enema because the patient develops bradycardia and hypotension. The nurse understands the response as a result of stimulating a specific nerve. Patient has had a

A vagal response, also known as a vasovagal response or a vasovagal reaction, is a specific type of reflex response that can occur when the vagus nerve is stimulated. The vagus nerve, also called the tenth cranial nerve, plays a crucial role in regulating various bodily functions, including heart rate, blood pressure, digestion, and respiratory rate.

When the vagus nerve is stimulated, it can lead to a sudden decrease in heart rate (bradycardia) and blood pressure (hypotension). This response is a protective mechanism of the body that can occur in response to certain triggers, such as:

Sudden pain or discomfort Stress or anxiety

Straining during bowel movements or urination

Sudden changes in body position, like sitting or standing up quickly (orthostatic changes) Certain medical procedures, including enemas, bladder catheterization, or blood draws

In the context of the question, the patient's bradycardia and hypotension occurred when the nurse was administering an enema. The introduction of fluid into the rectum during the enema procedure can potentially stimulate the vagus nerve, leading to a vagal response.

Recognizing and responding promptly to a vagal response is essential for patient safety. When a vagal response occurs, the nurse should stop the procedure, help the patient assume a comfortable position (such as lying down with legs elevated), and provide reassurance to reduce anxiety. If

necessary, the healthcare team may administer additional interventions to stabilize heart rate and blood pressure.

It is important for healthcare providers to be aware of potential vagal responses and take appropriate precautions during procedures to minimize the risk of adverse reactions in susceptible patients.
