Which of the following would result in an increase in blood pressure?
Decreased cardiac output
Decreased vascular resistance
Hypovolemia
Vasoconstriction
The Correct Answer is D
Choice A reason: Decreased cardiac output would result in a decrease in blood pressure, not an increase. Cardiac output is the amount of blood pumped by the heart per minute.
Choice B reason: Decreased vascular resistance would also result in a decrease in blood pressure, not an increase. Vascular resistance is the force that opposes the blood flow in the blood vessels.
Choice C reason: Hypovolemia would also result in a decrease in blood pressure, not an increase. Hypovolemia is the condition of having low blood volume due to fluid loss or dehydration.
Choice D reason: Vasoconstriction would result in an increase in blood pressure. Vasoconstriction is the narrowing of the blood vessels, which increases the vascular resistance and the blood pressure.

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.
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.
