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 D
Explanation
Choice A reason: Potassium is not restricted in the management of high blood pressure. In fact, potassium can help lower blood pressure by balancing the effects of sodium and relaxing the blood vessel walls.
Choice B reason: Magnesium is not restricted in the management of high blood pressure. Magnesium can also help lower blood pressure by regulating the calcium channels and improving the endothelial function.
Choice C reason: Calcium is not restricted in the management of high blood pressure. Calcium can also help lower blood pressure by inhibiting the renin-angiotensin system and reducing the vascular resistance.
Choice D reason: Sodium is restricted in the management of high blood pressure. Sodium can increase blood pressure by retaining water in the body and increasing the blood volume and pressure.
Correct Answer is B
Explanation
Choice A reason: ACE inhibitors do not lower heart rate. They lower blood pressure by blocking the conversion of angiotensin I to angiotensin II, which is a potent vasoconstrictor. Beta blockers are the drugs that lower heart rate and blood pressure.
Choice B reason: ACE inhibitors inhibit vasoconstriction. This is the correct statement that describes the action of these medications. By blocking the angiotensin II formation, they prevent the narrowing of the blood vessels and reduce the resistance to blood flow.
Choice C reason: ACE inhibitors do not increase aldosterone secretion. They decrease it. Aldosterone is a hormone that causes the kidneys to retain sodium and water, which increases blood volume and pressure. By blocking the angiotensin II formation, ACE inhibitors reduce the stimulation of aldosterone secretion and promote sodium and water excretion.
Choice D reason: ACE inhibitors do not promote sodium retention. They promote sodium excretion. As explained above, ACE inhibitors reduce the aldosterone secretion and prevent the kidneys from reabsorbing sodium and water. This lowers the blood volume and pressure.
