A physician has ordered subcutaneous injections of morphine every 4 hours as needed for pain for a
motor vehicle accident victim. Morphine has a high abuse potential and is categorized in which class of
drugs?
C-IV
C-III
C-II
C-I - correct answers C-II
Explanation:
Narcotics such as morphine are considered C-II drugs because of the high abuse potential with severe
dependence liability. C-I drugs have high abuse potential and are not accepted for medical use. C-III
drugs have a lesser abuse potential than C-II drugs and an accepted medical use. C-IV drugs have a low
abuse potential and limited dependence liability.

A client with a long-standing dermatologic health problem has been advised to use a drug with a local
effect. The nurse should recognize what characteristic of this drug?
It affects only the organ system in which it is metabolized.
The drug acts primarily at the site where it is applied.
The drug requires application at multiple sites.
It is effective only as long as it is in contact with skin. - correct answersThe drug acts primarily at the site
where it is applied.
Explanation:
Drugs with local effects, such as sunscreen lotions and local anesthetics, act mainly at the site of
application. Those with systemic effects are taken into the body, circulated through the bloodstream to
their sites of action in various body tissues, and eventually eliminated from the body. A drug with local
effect does not necessarily have to be applied at multiple sites, and its action may affect tissues long
after contact.
,The nurse is caring for a client that states, "This is so stressful. I have to smoke marijuana to bring myself
some peace." What behavior does the nurse identify this client is experiencing?
A first pass effect
A psychological dependence
A hypersensitivity reaction
A physical dependence - correct answersA psychological dependence
Explanation:
The client is experiencing a psychological dependence to marajuana and is using the drug as a
maladaptive coping mechanism to deal with stress. A physical dependence is a habitual use of a drug,
where negative physical withdrawal symptoms result from abrupt discontinuation. A first pass effect is
an action by which an oral drug is absorbed and carried directly to the liver, where it is inactivated by
enzymes before it enters the general bloodstream. A hypersensitivity reaction is an undesirable reaction
produced by a normal immune system.

The nurse is caring for a group of clients involved in phase 3 of a drug study. Which tasks is the nurse
supposed to perform in clinical testing? (Select all that apply.)
Address how clients feel about the clinical trial.
Note the pharmacologic and biologic effects of the drug carefully.
Prepare the IND application for the manufacturer.
Conduct postmarketing surveillance to monitor the drug for safety. - correct answersAddress how
clients feel about the clinical trial.
Note the pharmacologic and biologic effects of the drug carefully.
Explanation:
The nurse needs to address all the issues that bother volunteers during the clinical testing phase as well
as document necessary dosage proportion and the pharmacologic and biologic effects of the drug. It is
the FDA that conducts postmarketing surveillance to monitor drugs for safety and approve new drug
applications. As a nurse, the nurse should not impede the activities of the FDA.

A nurse is preparing to administer morphine and recognizes morphine as belonging to what
classification of controlled substance?
schedule III (C-III)
schedule IV (C-IV)
schedule V (C-V)
schedule II (C-II) - correct answersschedule II (C-II)
Explanation:
Morphine is a schedule II (C-II) controlled substance with a severe risk of abuse and dependence.
Schedule III drugs have a lower abuse potential and generally contain nonbarbiturate sedatives,
nonamphetamine stimulants, and limited amounts of certain narcotics. Schedule IV drugs are those with
less abuse potential than schedule III and limited dependence liability, including some sedatives,
antianxiety agents, and nonnarcotic analgesics. Schedule V medications have limited abuse potential
and are often found in small amounts in antitussives or antidiarrheals. Federal law allows purchase
without a prescription directly from a pharmacist if the purchaser is over age 18 and furnishes suitable
identification.

What is a major disadvantage of using over-the-counter (OTC) medications?
Consumers resist the effort to learn more about their condition.
There is a lack of autonomy.
People may choose an OTC that interacts with another medication.
Cause increased visits to the health care practitioner. - correct answersPeople may choose an OTC that
interacts with another medication.
Explanation:
Disadvantages of using an OTC include inaccurate self-diagnoses and potential risks of choosing a wrong
or contraindicated drug, delayed treatment by a health care professional, and development of adverse
drug reactions and interactions. Advances include greater autonomy, faster and more convenient access
