A patient who begins to take a parasympathetic agent is most likely to exhibit what new symptom? A.Increased blood pressureB.Increased heart rateC.Dilated bronchiolesD.Increased salivation

D. Increased salivation

Here's why:

The parasympathetic nervous system is responsible for the body's rest and digest function. When a parasympathetic agent is taken, it stimulates the parasympathetic nervous system. This leads to various effects such as slowing the heart rate, constricting the bronchioles, and stimulating the digestive system.

A. Increased blood pressure and B. Increased heart rate are associated with the sympathetic nervous system, which is responsible for the fight or flight response, not the parasympathetic system.

C. Dilated bronchioles are also a response of the sympathetic nervous system, as it prepares the body for intense physical activity by allowing more air to flow into the lungs.

D. Increased salivation is a response of the parasympathetic nervous system. It happens because the system stimulates the salivary glands to produce more saliva as part of the digestive process. So, a patient who begins to take a parasympathetic agent is most likely to exhibit increased salivation as a new symptom.
