You have ordered pilocarpine. You understand that the drug stimulates
muscarinic receptors.
Which action would you expect the drug to have? - ANS ✓Lowering of
intraocular pressure in pts with glaucoma
Also used to treat dry mouth because it increases salivary glands "Rest and
digest"
Muscarinic agents are related to parasympathetic response
You are teaching a nursing student about the two classes of adrenergic
agonist drugs.
Which statement by the nursing student indicates understanding of the
teaching? - ANS ✓Catecholamines often require continuous infusion to be
effective
Catecholamines undergo rapid degradtion by monoamine oxidase MAO and
COMT. 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 __________. - ANS ✓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.
What will you tell the student? - ANS ✓Epinephrine has the ability to activate
multiple types of adrenergic receptors
Beta 1 receptors increase CO and BP
Beta 2 receptors increase bronchodilation
Alpha 1 receptors causes vasoconstriction and increases HR and BP
Dopamine is administered to a patient who has been experiencing
hypotensive episodes.
Other than an increase in blood pressure, which indicator would the nurse
use to evaluate a successful response? - ANS ✓Increase in urine output
because of the increase in cardiac output which was a result of the increase in BP
A patient is taking a beta-adrenergic antagonist medication for angina
pectoris and asks the nurse how the drug works to relieve the discomfort
associated with this condition.
Which statement by the patient after the nurse's teaching indicates
understanding of the drug's effects? - ANS ✓Helps reduce the heart's oxygen
needs

Blocking beta 1 receptors in the heart reduces cardiac work by reducing
HR, force of contraction, and the velocity of impulse through the AV node
Beta blockers results in bronchoconstriction
CO decreased
A male patient is being treated for benign prostatic hyperplasia (BPH) and
has stopped taking his alpha-adrenergic antagonist medication because of
ejaculatory difficulties.
Which medication should you prescribe? - ANS ✓Alfuzosin
Does not interfere with ejaculation
What is true about phentolamine? - ANS ✓Acts on both alpha 1 and alpha 2
receptors
Blocks both epi and norepi mediated vasoconstriction
Alpha-Adrenergic antagonist!
Used to prevent tissue necrosis
Side effects are tachycardia and hypotension
What happens when alpha-adrenergic antagonists are administered? - ANS
✓Cardiac output is decreased as a result of the venous dilation cause by those
drugs
