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 A
Explanation
Choice A reason: This is the correct mechanism of action of propranolol. Propranolol is a beta blocker medication, which means that it blocks the beta receptors in the heart and blood vessels. This reduces the sympathetic stimulation in cardiac muscle, which lowers the heart rate, contractility, and oxygen demand. This also reduces the renin release from the kidneys, which lowers the blood pressure.
Choice B reason: This is not the mechanism of action of propranolol. Propranolol does not increase the diuretic response in the renal tubules. This is the effect of diuretic medications, such as furosemide or hydrochlorothiazide, which increase the urine output and decrease the blood volume and pressure.
Choice C reason: This is not the mechanism of action of propranolol. Propranolol does not inhibit the conversion of angiotensin I to angiotensin II. This is the effect of angiotensin-converting enzyme (ACE) inhibitors, such as lisinopril or enalapril, which block the formation of angiotensin II, a potent vasoconstrictor that raises the blood pressure.
Choice D reason: This is not the mechanism of action of propranolol. Propranolol does not block alpha receptors throughout the body. This is the effect of alpha blockers, such as doxazosin or prazosin, which block the alpha receptors in the blood vessels and cause vasodilation, which lowers the blood pressure.
Correct Answer is C
Explanation
Choice A reason: Glucocorticoids can cause an increase in blood sugar by stimulating gluconeogenesis and inhibiting insulin action. Therefore, a patient with type 1 diabetes who is taking glucocorticoids will not have no change in blood sugar, but rather a rise in blood sugar.
Choice B reason: Glucocorticoids can cause an increase in blood pressure by promoting sodium and water retention and increasing vascular reactivity. Therefore, a patient with type 1 diabetes who is taking glucocorticoids will not have a decrease in the blood pressure, but rather a possible increase in the blood pressure.
Choice C reason: Glucocorticoids can cause an increase in blood sugar by stimulating gluconeogenesis and inhibiting insulin action. Therefore, a patient with type 1 diabetes who is taking glucocorticoids will have an increase in blood sugar. This is the correct statement that describes the expected effect of glucocorticoids in this patient.
Choice D reason: Glucocorticoids can cause an increase in blood sugar by stimulating gluconeogenesis and inhibiting insulin action. Therefore, a patient with type 1 diabetes who is taking glucocorticoids will not have an increase in the need for carbohydrates, but rather a need for more insulin to control the blood sugar.
