A client is admitted to the emergency department with inspiratory stridor and air hunger. When anticipating treatment, the nurse will prepare Epinephrine medication for administration.

Using a G protein-linked second messenger pathway, epinephrine, a sympathomimetic catecholamine, exerts its pharmacologic effects on both alpha and beta-adrenergic receptors. In modest doses, it has a stronger affinity for beta receptors.

Large doses, however, have a selective effect on alpha receptors. Epinephrine causes enhanced vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction via acting on alpha-1 receptors.

Increased heart rate, myocardial contractility, and renin release via beta-1 receptors are additional major effects. In addition to vasodilation, tocolysis, and increased aqueous humour production, beta-2 effects result in bronchodilation, which may be helpful as an adjunct therapy for asthma exacerbations.

I believe it means that in order for someone to make you feel bad about yourself, you have to agree with what they are saying, and by agreeing you are giving them permission.  Everyone has a right to their own opinion but we don't have to buy into other people's opinion of us.
