COMPLETE QUESTIONS AND VERIFIED
ANSWERS
may need increased amounts of the drug over time
📌📌
When tolerance develops, a dose increase may be needed because a decreased response may
occur with prolonged use - - A patient asks his provider to explain what drug tolerance
means.
The provider responds by telling the patient that when tolerance occurs, it means the patient
__________.
Prevents some potentially toxic substances from crossing into the central nervous system
Infants are more sensitive to CNS drugs and require lower doses
Prevents highly ionized and protein-bound drugs from entering
Allows lipid-soluble drugs drugs and drugs that use specific transport systems to enter - 📌📌-
A group of nursing students asks a nurse to explain the blood-brain barrier.
The nurse would be correct to say that the blood-brain barrier __________.
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* - 📌📌- A pregnant
patient is in premature labor.
Which class of drug will she be given?
Alpha1 agonist - 📌📌- What type of drug class has effects on the heart and arterioles?
Urinary and GI tracts
They do not affect the urine muscles - 📌📌- Anticcholinergic drugs are given for what effects?
"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 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?
"The digestive functions of the body"
, Which answer indicates the need for further teaching?
Physostigmine (Mestinon, Regonol)
📌📌
Drug of choice for treating poisoning from atropine and other drugs that cause muscarinic
blockage ie: atropine (Muscarinic Antagonist) - - A patient is experiencing toxic side effects
from atropine, including delirium and hallucinations.
Which medication will the provider ask the nurse to administer?
Donepezil -📌📌- What drug is used to treat Alzheimer's Disease?
Take a supplementary dose before exercise - 📌📌- A patient who has myasthenia gravis will
be taking neostigmine.
What should the nurse emphasize when teaching this patient about the medication?
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 have ordered
pilocarpine. You understand that the drug stimulates muscarinic receptors.
Which action would you expect the drug to have?
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 - 📌📌- 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?
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 - - Because they cause vasoconstriction, alpha1-adrenergic agonists are
especially useful for __________.
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 - 📌📌 - A nursing student
asks you why epinephrine, and no other adrenergic agonists, is used to treat anaphylactic
shock.
What will you tell the student?
