Which class of drug will she be given? - ANSWER Beta 2 agonist (helper) Part of the peripheral adrenergic receptor subtypes (epi/norepi) Beta2 agonists cause relaxation of the uterine muscles, slowing or stopping the contractions that precipitate labor *Beta2 ANTagonist would increase constriction of the uterine muscles* What type of drug class has effects on the heart and arterioles? - ANSWER Alpha1 agonist Anticcholinergic drugs are given for what effects? - ANSWER Urinary and GI tracts They do not affect the urine muscles A nurse is explaining the activation of beta -2 receptors to nursing students during a clinical rotation at the hospital. Which statement by a student demonstrates a need for further teaching? - ANSWER "Beta2 activation results in contraction of the uterine muscles" *Beta2 activation DOES result in vasodilation of skeletal muscles, bronchodilation, and glycogenolysis, and RELAXATION of uterine muscles* A provider is teaching a patient about a medication that alters the sympathetic nervous system functions.

Brief duration of action and continuous IV to be effective They DO NOT cross the BBB, noncatecholamines do Noncatecholamines can be given orally but catehcholamines can not Because they cause vasoconstriction, alpha1 -adrenergic agonists are especially useful for __________. - ANSWER causing hemostasis in skin and mucous membranes Example is epinephrine These agents can increase BP but are not the primary drug used except in emergency situations A nursing student asks you why epinephrine, and no other adrenergic agonists, is used to treat anaphylactic shock.The benefits of buying summaries with Stuvia:
