1. What is pharmacokinetics?
a. The study of biological and therapeutic effects of drugs
b. The study of absorption, distribution, metabolism and excretion of drugs
c. The study of mechanisms of drug action
d. The study of methods of new drug development
ANSWER: B
RATIO: Because pharmacokinetics involves the study of drug absorption,
distribution, metabolism, and excretion, as well as how an organism affects a
drug, Option B is the correct answer. Pharmacokinetics is also abbreviated as
PK.
2. The interaction of one drug increased by the presence of a second drug is
known as:
a. Potentiation
b. Addictive effects
c. Antagonism
d. Synergism
ANSWER: A
RATIO: Option A is the correct answer because potentiation is known as the
interaction of one drug increased by the presence of a second drug, it does elicit
a response on its own but it enhances its response to another drug.
3. Considering the absorption of medications during administration, which of
the following routes would yield the quickest response?
a. Oral Medications
b. Subcutaneous injections
c. Intravenous medications
d. Topical medications
ANSWER: C
RATIO: Option C is the correct answer because Intravenous medication is the
fastest route of medication absorption and is most appropriate for people who are
experiencing severe pain.
4. Which of the following best defines the process of pharmacokinetics?
a. The effect of medication on the body
b. The effect of the body on medication
, c. The study of medications
d. The preparation of medications for administration
ANSWER: B
RATIO: Option B is the correct answer because pharmacokinetics is the process
of what the body does to a drug or basically the effect of the body on medication.
5. When performing an assessment about medication drug history should
include which of the following?
a. Complete vital signs
b. Reason for medication
c. Client’s goal therapy
d. Administration of OTC medications
ANSWER: D
RATIO: Option D is the correct answer because when we perform an
assessment about medication drug history, it is important for us to include
checking if the client is taking other medication especially OTC medications
because this helps us to prevent prescription errors and potential risks to our
patient.
6. When considering the pharmacotherapeutic effects of drugs administered
to clients, the nurse considers which property of most Importance:
a. Efficacy
b. Potency
c. Interaction with other drugs
d. Toxicity
ANSWER: A
RATIO: Option A is the correct answer because efficacy elicits the maximum
response/effect that can be achieved by the drug to the patient that is why nurses
should be careful and aware when administering a certain drug.
7. Safety of a drug is determined by the degree between which of the
following?
a. Therapeutic and toxic doses
b. Potency and efficacy
c. Subtherapeutic and toxic levels
d. Side and adverse effects
ANSWER: A
RATIO: Option A is the correct answer because safety of the drug is determined
by the degree between therapeutic and toxic doses, this means that when we
administer drug we should always know the degree of the toxicity of the drug or
whether it is right for the patient to take it or not.
,8. The nurse is monitoring the therapeutic drug level for a client on
vancomycin (Vancocin) and notes that the level is within the acceptable
range. What does this indicate to the nurse? Select all that apply.
a. The drug should cause no toxicities or adverse effects
b. The drug level is appropriate to exert therapeutic effects
c. The dose will not need to be changed for the duration of treatment
d. the nurse will need to continue monitoring because each client
response to a drug is unique
ANSWER: B and D
RATIO: Options B and D are the correct answers since the level of the drug is
within acceptable range, this means that the drug is appropriate to exert
therapeutic effect but, the nurse should still continue monitoring because not all
clients have the same response to certain drugs.
9. When a drug is 50% protein bound it means that:
a. 50% of the drug destroys protein
b. A drug not bound to protein is an active drug
c. 50% of the dose is at work
d. Protein must be restricted in the diet
ANSWER: C
RATIO: Option C is the correct answer because when a drug is 50% protein
bound, it means that 50% of the dose is at work and 50% is unable to be
effective.
10. When reviewing the patient’s medication regimen, the nurse understands
that the interval of drug dosage is related to what?
a. Half-life
b. Biotransformation
c. Metabolism
d. Therapeutic effect
ANSWER: A
RATIO: Option A is the correct answer because when reviewing the patient’s
medication regimen, the nurse understands that the interval of drug dosage is
related to half-life. Half-life of a drug is the time it takes for the amount of a drug's
active substance in the patient’s body to reduce by half.
11. It is important for the nurse to be aware of the four sequential processes of
the pharmacokinetic phase. What are these processes?
a. Distribution, metabolism, excretion, absorption
b. Biotransformation, excretion, absorption, metabolism
c. Absorption, distribution, metabolism, excretion
d. Metabolism, distribution, absorption, excretion
ANSWER: C
, RATIO: Option C is the correct answer because the four important sequential
processes of the pharmacokinetic phase are the absorption, distribution,
metabolism, and excretion.
12. The nurse is teaching the client about newly prescribed medication. Which
statement made by the client would indicated the need for further
medication education?
a. "the liquid form of the drug will be absorbed faster than the tablets."
b. "If I take more, I'll have a better response"
c. "taking this drug with food will decrease how much gets into my
system."
d. "I can consult my health care provider if i experience unexpected
adverse effects"
ANSWER: B
RATIO: Option B is the correct answer because the tendency of taking excess
drugs from the only amount of drug prescribed could overdose the patient, the
patient needs to further educated on the correct amount that should he/she
should be taking.
13. The nurse is caring for several clients. Which client will the nurse
anticipate is most likely to experience an alteration in drug metabolism?
a. A 3 day old premature infant
b. A 22 year old pregnant female
c. A 32 year old man with kidney stones
d. A 50 year old executive with hypertension
ANSWER: A
RATIO: Option A is the correct answer because a 3 day old premature infant is
most likely to experience an alteration in drug metabolism since infants do not
develop a mature microsomial enzyme system until they are a year old.
14. A client is being discharged from the hospital with a nebulizer for self-
administration of inhalation medication. Which statement made by the
client indicates to the nurse that the client education has been successful?
a. "Inhaled medications should only be taken in the morning."
b. "Doses for inhaled medications are larger than those taken orally"
c. "Medicines taken by inhalation produce a very rapid response."
d. "Inhaled drugs are often rendered inactive by hepatic metabolism
reaction”
ANSWER: C
RATIO: Option C is the correct answer because it is true that medicines taken by
inhalation produce a very rapid response especially for asthmatic patients.
Therefore, the client education has been successful.
