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: The cells of the myocardium become hypertrophic in response to increased workload or pressure, not as a result of myocardial infarction. Hypertrophy is an adaptive mechanism that can lead to impaired ventricular function over time.
Choice B reason: The resulting hypoxia leads to ischemic injury and myocardial cell death. This is the main cause of impaired ventricular function after a myocardial infarction. The loss of viable myocardial tissue reduces the contractility and pumping ability of the heart.
Choice C reason: There is a temporary alteration in electrolyte balance that can be corrected. This is not the primary cause of impaired ventricular function after a myocardial infarction. Electrolyte imbalance can occur due to fluid loss, renal impairment, or medication side effects, but it can be managed with appropriate interventions.
Choice D reason: There is too much pressure on the heart and the ventricles begin to dysfunction. This is not the direct cause of impaired ventricular function after a myocardial infarction. Increased pressure on the heart can result from hypertension, valvular disease, or pulmonary embolism, but it is not related to myocardial ischemia or necrosis.
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.
