Empyema is defined as an

infection in the blood.

infection in the pleural space.

exudative bronchitis.

infection localized in the lung.

Answer and Explanation

The Correct Answer is B

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 A

Explanation

Choice A reason: Decrease in wheezing present on auscultation indicates that albuterol was effective. Albuterol is a bronchodilator that relaxes the smooth muscles of the airways and reduces the airway resistance. This improves the airflow and reduces the wheezing sound that is caused by the turbulent flow of air through the narrowed airways.

Choice B reason: Respiratory rate increased to 38 breaths/min does not indicate that albuterol was effective. It indicates that the patient is still experiencing respiratory distress and hypoxia. The normal respiratory rate for adults is 12 to 20 breaths/min. A high respiratory rate can also be a side effect of albuterol, as it can stimulate the sympathetic nervous system and increase the heart rate and blood pressure.

Choice C reason: Sputum production is clear and watery does not indicate that albuterol was effective. It indicates that the patient has a productive cough and is expelling mucus from the lungs. Sputum production is not directly affected by albuterol, as it does not have anti-inflammatory or mucolytic properties.

Choice D reason: Use of neck muscles does not indicate that albuterol was effective. It indicates that the patient is using accessory muscles to breathe and is exerting more effort to inhale. This is a sign of severe respiratory distress and airway obstruction. Albuterol should relieve the bronchospasm and reduce the need for accessory muscle use.

A. Hypertension B. Dyspnea upon exertion C. Significant edema to both lo D. Decreased urine output

Correct Answer is C

Explanation

Choice A reason: This is not a symptom of right heart failure. Hypertension is a risk factor for developing heart failure, but it does not indicate the severity or location of the heart failure.

Choice B reason: This is not a symptom of right heart failure. Dyspnea upon exertion is a symptom of left heart failure, which occurs when the left ventricle fails to pump blood effectively to the lungs.

Choice C reason: This is a symptom of right heart failure. Significant edema to both lower legs and feet is a result of increased pressure in the systemic circulation, which occurs when the right ventricle fails to pump blood effectively to the rest of the body. This causes fluid to accumulate in the dependent areas, such as the lower extremities.

Choice D reason: This is not a symptom of right heart failure. Decreased urine output is a symptom of left heart failure, which occurs when the left ventricle fails to pump blood effectively to the aorta and the rest of the body. This causes reduced renal perfusion and oliguria.
