A nurse is preparing to give an oral dose of drug X to treat a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
patient's high blood pressure. After giving the drug, the nurse
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
finds that it not only reduces the blood pressure without serious
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
harmful effects, but it also causes the patient to have nausea
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
and headache. Based on this information, which property of an
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ideal drug is this drug lacking?
|\ |\ |\ |\ |\
A. Effectiveness
|\
B. Safety |\
C. Selectivity
|\
D. Ease of administration - CORRECT ANSWERS ✔✔C. Selectivity
|\ |\ |\ |\ |\ |\ |\ |\ |\
Correct
The drug is effective in lowering the blood pressure and safe in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
that it does not cause harmful effects. However, as do most
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
drugs, it causes other effects besides the one response desired;
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
therefore, it lacks selectivity. The oral form provides ease of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
administration.
The nurse is preparing to give a drug with certain properties.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Which property of the drug is the most compelling indication that
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
it should not be given?
|\ |\ |\ |\ |\
A. The drug produces an unwanted side effect.
|\ |\ |\ |\ |\ |\ |\
B. The drug is difficult to administer.
|\ |\ |\ |\ |\ |\
C. The drug's effects are reversible.
|\ |\ |\ |\ |\
D. The drug is not effective for its intended purpose. - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔D. The drug is not effective for its intended
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
purpose. Correct |\
,If a drug is not effective, there is no justification for giving it.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Some drugs may be given even though they produce unwanted
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
side effects or are difficult to administer. Reversible action is a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
desired property for most drugs. |\ |\ |\ |\
Why is it important for drugs to have ease of administration?
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
A. Fewer administration errors
|\ |\ |\
B. Less risk of side effects
|\ |\ |\ |\ |\
C. Greater chemical stability
|\ |\ |\
D. Greater likelihood of reversibility - CORRECT ANSWERS ✔✔A.
|\ |\ |\ |\ |\ |\ |\ |\ |\
Fewer administration errors Correct |\ |\ |\
Ease of administration increases convenience and adherence and
|\ |\ |\ |\ |\ |\ |\
can reduce administration errors. Ease of administration is not
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
related to side effects, chemical stability, or reversibility.
|\ |\ |\ |\ |\ |\ |\
The nurse teaches a patient not to consume alcohol with
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
nitroglycerine, because the blood pressure often drops |\ |\ |\ |\ |\ |\ |\
significantly when nitroglycerine is taken with alcohol. Which |\ |\ |\ |\ |\ |\ |\ |\
drug property does this illustrate?
|\ |\ |\ |\
A. Chemical instability
|\ |\
B. Drug interaction
|\ |\
C. Reversible action
|\ |\
D. Drug selectivity - CORRECT ANSWERS ✔✔B. Drug interaction
|\ |\ |\ |\ |\ |\ |\ |\ |\
Correct
When two or more drugs are taken together, they can interact,
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
causing either increased or decreased drug responses. In this
|\ |\ |\ |\ |\ |\ |\ |\ |\
case, alcohol would increase the nitroglycerine response.
|\ |\ |\ |\ |\ |\ |\
,Chemical instability, reversible action, and drug selectivity are
|\ |\ |\ |\ |\ |\ |\ |\
not related to this situation.
|\ |\ |\ |\
When studying the impact a drug has on the body, the nurse is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
reviewing what? |\
A. The drug's pharmacokinetics
|\ |\ |\
B. The drug's selectivity
|\ |\ |\
C. The drug's pharmacodynamics
|\ |\ |\
D. The drug's predictability. - CORRECT ANSWERS ✔✔C. The
|\ |\ |\ |\ |\ |\ |\ |\ |\
drug's pharmacodynamics Correct
|\ |\
Pharmacodynamics can be thought of as the impact of drugs on |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the body. Pharmacokinetics describes the movement of drugs
|\ |\ |\ |\ |\ |\ |\ |\
through the body. Selectivity is the ability of a drug to elicit only
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the response for which it is given. Predictability is the degree of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
certainty about how a patient will respond to a certain drug.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
When studying the effects of drugs in humans, the nurse is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
learning about what? |\ |\
A. Pharmacology
|\
B. Clinical pharmacology
|\ |\
C. Therapeutics
|\
D. Effectiveness - CORRECT ANSWERS ✔✔B. Clinical
|\ |\ |\ |\ |\ |\ |\
pharmacology Correct |\
Clinical pharmacology is the study of the effects of drugs in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
humans. Pharmacology can be defined as the study of drugs and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
their interactions with living systems. Therapeutics, also known
|\ |\ |\ |\ |\ |\ |\ |\
as pharmacotherapeutics, is the use of drugs to diagnose,
|\ |\ |\ |\ |\ |\ |\ |\ |\
prevent, or treat disease or to prevent pregnancy. The term
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
, effectiveness indicates that the drug elicits the intended |\ |\ |\ |\ |\ |\ |\ |\
response or responses. |\ |\
Which statement by a new nurse indicates that further study is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
indicated?
A. Effectiveness is the most important property a drug can have.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
B. There is no such thing as a safe drug.
|\ |\ |\ |\ |\ |\ |\ |\ |\
C. Drugs are defined as illegal substances.
|\ |\ |\ |\ |\ |\
D. There is no such thing as a selective drug; all medications
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
cause side effects. - CORRECT ANSWERS ✔✔Drugs are defined as
|\ |\ |\ |\ |\ |\ |\ |\ |\
illegal substances. Correct
|\ |\ |\
A drug is any chemical that can affect living processes. All the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
other statements are correct.
|\ |\ |\
What is the ultimate concern for the nurse when administering a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
drug?
A. Intensity of the response
|\ |\ |\ |\
B. Dosage |\
C. Route of administration
|\ |\ |\
D. Timing of administration - CORRECT ANSWERS ✔✔A. Intensity
|\ |\ |\ |\ |\ |\ |\ |\ |\
of the response Correct
|\ |\ |\
The ultimate concern for the nurse when administering a drug is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the intensity of the response, which is determined by the dosage
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
size, route of administration, and timing of administration.
|\ |\ |\ |\ |\ |\ |\
What is the objective of drug therapy?
|\ |\ |\ |\ |\ |\
A. To provide maximum benefit with minimal harm
