Question 1

How do you remember Albuterol?

Accepted Answer

Albuterol breaks down as AL = all + BUTER = breather + OL = all. Break albuterol into AL (sounds like all), BUTER (sounds like breather), and OL (sounds like all). Albuterol is all - breather - all. In an asthma attack, the airways clamp shut. You know that albuterol acts on beta-2, because breather starts with b and there's 2 alls, thus beta-2 agonist. It relaxes airway smooth muscle, so you can breathe. Beta-2 on, airways open.

Question 2

What class of drug is Albuterol?

Accepted Answer

Albuterol is a Beta-2 Agonist • Bronchodilator • Asthma Rescue.

Question 3

How is Albuterol tested on the USMLE?

Accepted Answer

Albuterol is a short-acting beta-2 agonist. Activating beta-2 receptors relaxes bronchial smooth muscle, opening the airways within minutes, which makes it the go-to rescue inhaler for an acute asthma attack. Beta-2 selectivity is why it targets lungs more than heart.

Question 4

An asthmatic child is given repeated high-dose nebulized albuterol in the ER for a severe attack. A few hours later, routine labs show a potassium of 3.1. What best explains this drop?

Accepted Answer

A - Beta-2 agonists activate the Na-K-ATPase pump, driving potassium from the blood into cells and lowering serum potassium. This intracellular shift is exactly why albuterol is also used to treat hyperkalemia. B describes a renal mechanism albuterol doesn't have, C is not the cause here, and D is a made-up lab artifact.
