What is albuterol (Proventil) used to treat?
Acute allergies
Nasal congestion
Dyspnea on exertion
Acute bronchospasm
The Correct Answer is D
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.

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.
Correct Answer is D
Explanation
Choice A reason: This is not a sign of left-sided heart failure. Jugular vein distension is a sign of right-sided heart failure, which occurs when the right ventricle fails to pump blood effectively to the lungs.
Choice B reason: This is not a sign of left-sided heart failure. Increased blood pressure is a risk factor for developing heart failure, but it does not indicate the severity or location of the heart failure.
Choice C reason: This is not a sign of left-sided heart failure. Hepatomegaly is a sign of right-sided heart failure, which occurs when the right ventricle fails to pump blood effectively to the systemic circulation.
Choice D reason: This is a sign of left-sided heart failure. Decreased urine output is a result of reduced renal perfusion, which occurs when the left ventricle fails to pump blood effectively to the aorta and the rest of the body.
