"The exact mechanism for tremor induction by β(2)-adrenergic agonists is still unknown, but there is some evidence that β(2)-adrenergic agonists act directly on muscle... More recently, tremor has been correlated closely with hypokalaemia." - NIH publication
First Aid mentions hyperthyroidism causing tremor from β-adrenergic stimulation. It also mentions β2-agonists causing tremor as a side effect. First Aid also mentions β2-agonists driving potassium into cells, which may contribute to tremor. That said, more classic symptoms of hypokalemia are wide QRS and peaked T waves on ECG, arrhythmias, and muscle weakness.
Looking around on the internet looks like if therapy is continued the tremor from a β2-agonists resolves overtime.
Albuterol - relaxes bronchial smooth muscle (short acting β2-agonist). For acute exacerbations. Can cause tremor, arrhythmia.
This probably isn't 100% politically correct but:
Beta 2 agonist is still a beta agonist so it can bind nonspeficially and cause B1 activation which will cause tremor aka activates general sympathetics.
Sweating is generally can be categorized as sympathetic activation but the sweat gland has a muscarinic receptor so it won't be affected by a beta agonist.
the remaining choices are parasympathetic responses.
is no one else concerned about the fact that theyre giving a beta 2 agonist to a woman whos 28 weeks pregnant.......?
if put diaphoresis because beta 2agonist increase insulin cause hypoglycemia then leading to diaphoresis ? could anybody explain
I thought of it as, a Beta agonist would cause vasodilation, and reflex tachycardia, her pulse is already at 100, so it would jump higher. She could get palpitations and tremors. Probably the least likely explanation out of the rest though.

The way I thought about it was a little more simplistic. We use non selective beta blockers (e.g. Propranolol) for the treatment of essential tremor. Therefore a beta agonist would have the opposite effect, aka cause or enhance tremor.
