ANSWERS GRADED A+/
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
Ans: 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.
Quiz 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.
Ans: 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.
Quiz 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
Ans: 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.
Quiz 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
Ans: 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.
Quiz 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.
, Ans: 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.
Quiz When studying the effects of drugs in humans, the nurse is learning about
what?
A. Pharmacology
B. Clinical pharmacology
C. Therapeutics
D. Effectiveness
Ans: 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.
Quiz 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.
