Left-sided heart failure is characterized by
jugular vein distention.
peripheral edema.
decreased systemic vascular resistance.
pulmonary congestion.
The Correct Answer is D
Choice A reason: Jugular vein distention is a sign of right-sided heart failure, not left-sided. It indicates increased pressure in the right atrium and vena cava.
Choice B reason: Peripheral edema is also a sign of right-sided heart failure, not left-sided. It indicates fluid retention in the lower extremities and abdomen.
Choice C reason: Decreased systemic vascular resistance is not a characteristic of left-sided heart failure. It is a compensatory mechanism that occurs in response to reduced cardiac output.
Choice D reason: Pulmonary congestion is a characteristic of left-sided heart failure. It indicates fluid accumulation in the lungs due to the inability of the left ventricle to pump blood effectively.

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.
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.
