The correct answers are "ciprofloxacin is an antibiotic", "albuterol is a bronchodilator", and "prednisone is a corticosteroid". Ciprofloxacin is an antibiotic in the class of fluoroquinolones, effective against respiratory infections since patients with COPD has mucus hypersecretion which predisposes the patient to respiratory infections. Other antibiotics include respiratory fluoroquinolones such as levofloxacin and moxifloxacin, cephalosporins such as cefuroxime and ceftriaxone, and beta-lactams such as co-amoxiclav. Albuterol is a short acting beta-agonist (SABA) which actions as a bronchodilator by relaxing bronchial smooth muscles. Other popular SABA is salbutamol. Prednisone is a corticosteroid which actions to prevent inflammation by blocking the arachidonic acid pathway and therefore block the formation of inflammatory mediators.
Decadron is dexamethasone which is a steroid. Bactrim is TMP/SMX which is an antibiotic.

Answer:
An experiment imposes treatment on the subjects, but an observational study does not
Explanation:
Observational studies are research studies in which an effect, process behaviour etc. are observed, without any change. For example, observation of the possible effect of a treatment on subjects.
On the other hand, experimental studies are studies in which the treatment is included. Experimental studies are randomized, meaning that subjects that are in experiment are randomly put to a treated group or a control group.
