How does montelukast (Singulair), a leukotriene blocker, work in the treatment of asthma?

Increased vessel permeability

Reduced bronchoconstriction and mucus secretion

Increased inflammation

Increased bronchoconstriction

Answer and Explanation

The Correct Answer is B

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 D

Explanation

Choice A reason: The patient should not use the glucocorticoid as needed when symptoms flare. The glucocorticoid is a long-term controller medication that reduces inflammation and prevents exacerbations of COPD. It should be used regularly as prescribed, not as a rescue medication.

Choice B reason: The patient does not need to use the beta2-adrenergic agonist drug daily even when they don't have any symptoms. The beta2-adrenergic agonist is a short-acting bronchodilator that relaxes the smooth muscles of the airways and improves airflow. It should be used as needed for relief of acute symptoms, not as a maintenance medication.

Choice C reason: The beta2-adrenergic agonist does not suppress the synthesis of inflammatory mediators. The beta2-adrenergic agonist is a bronchodilator that acts on the beta2 receptors of the airways and causes relaxation of the smooth muscles. It does not have any anti-inflammatory effects.

Choice D reason: The glucocorticoid is used as prophylaxis to prevent exacerbations every day. This is the correct statement that indicates understanding of this medication regimen. The glucocorticoid is a long-term controller medication that reduces inflammation and prevents exacerbations of COPD. It should be used regularly as prescribed, along with the beta2-adrenergic agonist as needed for relief of acute symptoms.

A. Decreased cardiac output B. Decreased vascular resistance C. Hypovolemia D. Vasoconstriction

Correct Answer is D

Explanation

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.
