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: Respiratory acidosis does not cause no change in affinity of hemoglobin with oxygen. It causes a decrease in affinity of hemoglobin with oxygen, which means that hemoglobin releases more oxygen to the tissues. This is known as the Bohr effect, which is a physiological response to low pH and high CO2 levels.

Choice B reason: Respiratory acidosis causes a decrease in affinity of hemoglobin with oxygen, which means that hemoglobin releases more oxygen to the tissues. This is the correct statement that describes the expected finding in this patient. The decrease in affinity of hemoglobin with oxygen is a compensatory mechanism that tries to restore the oxygen balance in the body.

Choice C reason: Respiratory acidosis does not cause an increase in affinity of hemoglobin with oxygen. It causes a decrease in affinity of hemoglobin with oxygen, which means that hemoglobin releases more oxygen to the tissues. An increase in affinity of hemoglobin with oxygen would mean that hemoglobin holds on to oxygen more tightly, which would worsen the hypoxia in the patient.

Choice D reason: Respiratory acidosis does not cause a decrease in blood CO2. It causes an increase in blood CO2, which is the primary cause of the low pH. A decrease in blood CO2 would indicate respiratory alkalosis, which is a condition of high pH and low CO2 levels.

A. Acute allergies B. Nasal congestion C. Dyspnea on exertion D. Acute bronchospasm

Correct Answer is D

Explanation

Choice A reason: Albuterol is not used to treat acute allergies. It is a bronchodilator that relaxes the smooth muscles of the airways and improves airflow. Antihistamines are the drugs of choice for acute allergies.

Choice B reason: Albuterol is not used to treat nasal congestion. It is a bronchodilator that acts on the lungs, not the nose. Decongestants are the drugs of choice for nasal congestion.

Choice C reason: Albuterol is not used to treat dyspnea on exertion. It is a bronchodilator that is used for acute or chronic respiratory conditions, such as asthma or chronic obstructive pulmonary disease (COPD). Dyspnea on exertion is a symptom of various cardiac or pulmonary disorders that require further evaluation and treatment.

Choice D reason: Albuterol is used to treat acute bronchospasm. It is a bronchodilator that quickly relieves the symptoms of bronchoconstriction, such as wheezing, coughing, and shortness of breath. It is often prescribed as a rescue inhaler for patients with asthma or COPD.
