Pharm Test 1 Practice Questions -LehneA 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 reduces the blood pressure without serious harmful
effects, but it also causes the patient to have nausea and a 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 - ANSC
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. - ANSD
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 medication errors
b) less risk of side effects
c) Greater chemical stability
d) Greater likelihood of reversibility - ANSA
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 - ANSB
,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 - ANSC
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 - ANSB
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. - ANSC
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 - ANSA
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.
, The nurse is preparing to administer a dose of penicillin. Before administering the medication,
the nurse assesses the patient's allergy history. Which aspect of drug therapy does this
represent?
A)Making PRN (as needed) decisions
B)Evaluating therapeutic effects
C)Ensuring proper dosage
D)Identifying high-risk patients - ANSD
Patients receiving penicillin are at high risk for dangerous allergic reactions. This intervention
represents the nurse's role in identifying situations with high risk. This situation does not
represent the remaining responses.
The nurse is preparing to administer a medication with the following order: "Aldomet 250 mg
daily." What should the nurse do?
A)Administer the medication as it was given last time.
B) Administer the medication by mouth.
C) Verify the order with the prescriber. Correct
D) Ask the patient how this medication is usually given. - ANSC
This order does not include a drug route. The nurse should clarify any questionable orders with
the prescriber. The other responses are incorrect.
Which aspect of drug therapy indicates to the nurse whether a drug is having a beneficial effect?
A)Performing a preadministration assessment
B)Evaluating therapeutic responses Correct
C) Minimizing adverse effects
D) Managing toxicity - ANSB
Evaluation is one of the most important aspects of drug therapy, because it tells the nurse
whether a drug is having its intended effect. The other aspects of drug administration are
important but do not give information about a drug's effectiveness.
The nurse is managing the care of a group of patients with cancer who will be receiving
chemotherapy. The nurse defines goals, sets priorities, identifies interventions, and establishes
criteria for evaluating success. Which phase of the nursing process does this represent?
A) Assessment
B) Planning Correct
C) Implementation
D) Evaluation - ANSB
These activities are all carried out in the planning phase of the nursing process. Assessment is
a time of data gathering, implementation begins with carrying out the interventions, and
evaluation is performed to determine the degree to which treatment has succeeded
The nurse identifies what as the goal of drug therapy in the treatment of patients?
