Final answer:
For bronchospasm treated with albuterol, an anticholinergic bronchodilator is a suitable additional medication to help relax and open the airways. Sympatholytics are not typically used as they may exacerbate symptoms.
Step-by-step explanation:
If a patient is being treated for bronchospasm with an adrenergic bronchodilator like albuterol and requires additional medication, an anticholinergic bronchodilator could be recommended. This type of medication acts differently than adrenergic bronchodilators by blocking the action of acetylcholine on the muscles in the airways, which helps relax and open up the air passages further. Sympatholytics, on the other hand, like β-blockers, are usually not used as they can potentially exacerbate asthma symptoms by leading to further bronchoconstriction. Therefore, the correct answer would be A. Anticholinergic bronchodilator.
