1. 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 __________.: 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
2. 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 __________.: Pre-
vents 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
3. A pregnant patient is in premature labor.
Which class of drug will she be given?: 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*
4. What type of drug class has effects on the heart and arterioles?: Alpha1 agonist
5. Anticcholinergic drugs are given for what effects?: Urinary and GI tracts
They do not affect the urine muscles
6. 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?: -
"Beta2 activation results in contraction of the uterine muscles"
, WGU D116 Unit 3

*Beta2 activation DOES result in vasodilation of skeletal muscles, bronchodilation, and glycogenolysis, and RELAX-
ATION of uterine muscles*
7. A provider is teaching a patient about a medication that alters the sym-
pathetic nervous system functions. To evaluate understanding, the provider
asks the patient to describe which functions the sympathetic nervous system
regulates.
Which answer indicates the need for further teaching?: "The digestive functions of the
body"
All apart of the sympathetic nervous system:
1. fight or flight
2. cardiovascular system
3. body temperature
8. A patient is experiencing toxic side effects from atropine, including delirium
and hallucinations.
Which medication will the provider ask the nurse to administer?: Physostigmine
(Mestinon, Regonol)
Drug of choice for treating poisoning from atropine and other drugs that cause muscarinic blockage ie: atropine
(Muscarinic Antagonist)
9. What drug is used to treat Alzheimer's Disease?: Donepezil
10. A patient who has myasthenia gravis will be taking neostigmine.
What should the nurse emphasize when teaching this patient about the
medication?: Take a supplementary dose before exercise
11. You have ordered pilocarpine. You understand that the drug stimulates
muscarinic receptors.
Which action would you expect the drug to have?: 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

12. You are teaching a nursing student about the two classes of adrenergic
agonist drugs.
Which statement by the nursing student indicates understanding of the teach-
ing?: 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
13. Because they cause vasoconstriction, alpha1-adrenergic agonists are espe-
cially useful for __________.: 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
14. A nursing student asks you why epinephrine, and no other adrenergic
agonists, is used to treat anaphylactic shock.
What will you tell the student?: 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
15. Dopamine is administered to a patient who has been experiencing hy-
potensive episodes.
Other than an increase in blood pressure, which indicator would the nurse use
to evaluate a successful response?: Increase in urine output because of the increase in cardiac
output which was a result of the increase in BP
