Question 1 10 out of 10 points
A nursing student asks a nurse about pharmaceutical research and
wants to know the purpose of randomization in drug trials. The nurse
explains that randomization is used to do what?
Response Randomization helps prevent allocation bias, which can
Feedback: occur when researchers place subjects with desired
characteristics in the study group and other subjects in the
control group so that differences in outcome are actually
the result of differences in subjects and not treatment.
Comparing treatment outcome to no treatment outcome is
the definition of a controlled study. The last two options
describe the use of blinding in studies; blinding ensures
that researchers or subjects (or both) are unaware of
which subjects are in which group so that preconceptions
about benefits and risks cannot bias the results.

The nurse is administering morning medications. The nurse gives a
patient multiple medications, two of which compete for plasma albumin
receptor sites. As a result of this concurrent administration, the nurse
can anticipate that what might occur? (Select all that apply.)
Response When two drugs bind to the same site on plasma albumin,
Feedback: coadministration of those drugs produces competition for
binding. As a result, binding of one or both agents is
reduced, causing plasma levels of free drug to rise. The
increase in free drug can intensify the effect, but it usually
undergoes rapid elimination. The increase in plasma
levels of free drug is rarely sustained.
Question 3 10 out of 10 points
The U.S. Food and Drug Administration (FDA) recommends genetic
testing of patients receiving certain medications. Genetic testing helps
prescribers:
Response Pharmacogenomics is the study of the ways genetic
Feedback: variations affect individual responses to drugs through
alterations in genes that code for drug-metabolizing
enzymes and drug receptors. For some drugs, the FDA
requires genetic testing, and for others, this testing is
recommended but not required. Genetic testing does not
determine a drug’s therapeutic index; this is a measure of
a drug’s safety based on statistics of the drug’s use in the
general population (see Chapter 5). Any distinct
physiologic differences in drug response among various
racial populations are related to genetic differences and do
not affect psychosocial differences in drug responses.
Genetic testing is recommended to identify how a patient
will respond to a drug and not to design a drug specific to
an individual.
Question 4 10 out of 10 points
A patient is receiving digoxin twice daily. When assessing the patient
before giving a dose, the nurse counts a pulse of 60 beats/min and
learns that the patient is experiencing nausea. The nurse consults a
drug manual and verifies that the ordered dose is correct. What should
the nurse do?
Response The symptoms indicate toxicity, and even though the dose
Feedback: is safe and effective in most cases, an individual patient
may have toxic effects with a standard dose. The nurse
should contact the prescriber to discuss the next steps.
Delaying a dose without a change in order is not within the
scope of practice for a nurse. The nurse should not give a
dose of a medication when toxicity is suspected, because
additional drug will compound the symptoms. Antiemetics
