What will happen when a person is hypotensive?
Baroreceptors are less active
SNS is activated
Person will be bradycardic
SNS is suppressed
The Correct Answer is B
Choice A reason: This is not what will happen when a person is hypotensive. Baroreceptors are sensory receptors that detect changes in blood pressure. When a person is hypotensive, the baroreceptors are more active, not less, and they send signals to the brain to increase the blood pressure.
Choice B reason: This is what will happen when a person is hypotensive. SNS stands for sympathetic nervous system, which is the part of the autonomic nervous system that prepares the body for fight or flight response. When a person is hypotensive, the SNS is activated to increase the heart rate, contractility, and vasoconstriction, which all raise the blood pressure.
Choice C reason: This is not what will happen when a person is hypotensive. Person will be bradycardic means that the person will have a slow heart rate, usually below 60 beats per minute. When a person is hypotensive, the opposite will happen, as the heart rate will increase to compensate for the low blood pressure.
Choice D reason: This is not what will happen when a person is hypotensive. SNS is suppressed means that the sympathetic nervous system is inhibited or reduced in activity. When a person is hypotensive, the SNS is not suppressed, but rather stimulated, to increase the blood pressure.

Correct Answer is B
Explanation
Choice A reason: Infection in the blood is not empyema. It is sepsis, which is a life-threatening condition that occurs when the body's response to infection causes tissue damage, organ failure, or death.
Choice B reason: Infection in the pleural space is empyema. It is a collection of pus in the space between the lungs and the chest wall, usually caused by a bacterial infection that spreads from the lungs or the chest cavity.
Choice C reason: Exudative bronchitis is not empyema. It is a type of bronchitis that involves inflammation and excess mucus production in the bronchi, the airways that carry air to the lungs.
Choice D reason: Infection localized in the lung is not empyema. It is pneumonia, which is an inflammation of the lung tissue, usually caused by a viral or bacterial infection that affects the air sacs or the interstitial tissue.
Correct Answer is B
Explanation
Choice A reason: Montelukast does not increase vessel permeability. It blocks the effects of leukotrienes, which are inflammatory mediators that cause vessel permeability, bronchoconstriction, and mucus secretion. By blocking leukotrienes, montelukast reduces vessel permeability and inflammation.
Choice B reason: Montelukast reduces bronchoconstriction and mucus secretion. It blocks the effects of leukotrienes, which are inflammatory mediators that cause bronchoconstriction and mucus secretion. By blocking leukotrienes, montelukast improves airflow and reduces asthma symptoms.
Choice C reason: Montelukast does not increase inflammation. It blocks the effects of leukotrienes, which are inflammatory mediators that cause inflammation, bronchoconstriction, and mucus secretion. By blocking leukotrienes, montelukast reduces inflammation and prevents asthma exacerbations.
Choice D reason: Montelukast does not increase bronchoconstriction. It blocks the effects of leukotrienes, which are inflammatory mediators that cause bronchoconstriction, mucus secretion, and inflammation. By blocking leukotrienes, montelukast reduces bronchoconstriction and improves airflow.
