Option C, Parasympathetic nervous system stimulation resulting in airway constriction

Explanation:

Complete Question

When a client with a history of asthma takes a walk outside on a windy day with high pollen counts, she may experience an asthma attack, resulting in an increase in respiration rate and wheezing. The body's response is likely related to which pathophysiological principle?

Select one:

a. Influx of macrophages to wall of the pollen, thereby stopping the attack

b. Release of catecholamines causing blood vessel constriction

c. Parasympathetic nervous system stimulation resulting in airway constriction

d. Inhibition of glandular secretions, which causes build up of mucus in the lungs

Solution

The parasympathetic nervous system consists of cranial and sacral spinal nerves. It is responsible for doing the work of sympathetic system thereby decreasing the rate of respiration and heart. During windy climate when pollen grains are in excess, the rate of respiration needs to be higher in order to get sufficient supply of oxygen.

Monoamine oxidase inhibitors cause an antidepressant effect by
uranmaximum [27]

Answer:

C. inhibiting the breakdown of neurotransmitters in the brain

Explanation:

Monoamino oxidase (MAO) facilitates the break down and removal of neurotransmitters like nor-epinephrine, epinephrine, serotonin in brain which have excitatory effects on neurons. When these neurotransmitters are degraded by MAO, this would lead to decreased excitatory level of neurons and it will become less functionable as seen in most of the patients suffering from depression, panic disorders, social disphobia and some neurodegenerative disease.

Monoaminooxidase Inhibitors prevents the degradation of above mentioned neurotransmitters which leads to increasing their levels and concentration which allows them to work and influence on neurons effected by depression.
