Which of the following terms describes a therapy that provides medication via inhalation?

The correct term to describe a therapy that provides medication via inhalation is "NEB," which stands for nebulization. A nebulizer is a device that converts liquid medication into a mist, allowing it to be inhaled directly into the lungs through a mask or mouthpiece. This method is particularly beneficial for delivering respiratory medications, such as bronchodilators and steroids, directly to the airways, facilitating rapid relief from conditions like asthma or chronic obstructive pulmonary disease (COPD).

In contrast, the other terms refer to different routes of medication administration. "DM" does not specifically pertain to a recognized route of therapy; it can refer to "disease management" but does not relate directly to inhalation. "IV" stands for intravenous, indicating that medication is delivered directly into the bloodstream through a vein. "PO" means per os, or orally, referring to medications taken by mouth. Each of these methods serves different clinical purposes and is appropriate for various types of medications and conditions, but none align with inhalation therapy as accurately as nebulization does.
