Final answer:
The nurse anticipates administering Alupent, a beta-2 adrenergic agonist bronchodilator, which is a short-acting medication administered only by inhaler.
Step-by-step explanation:
The beta-2 adrenergic agonist agent (bronchodilator) that is short-acting and administered only by inhaler is Alupent. Alupent is a medication that acts on certain receptors in the airways to relax and widen them, making it easier to breathe. It is commonly used in the treatment of asthma and other obstructive pulmonary diseases.
