A patient with a recent diagnosis of acute renal failure has a long-standing
seizure disorder which has been successfully controlled for several years
with antiseizure medications. The nurse should recognize that the
patient's compromised renal function will likely
Response
Feedback:
Impaired renal function will increase the half-life of drugs that
are metabolized by the kidneys. This does not necessarily
render such medications ineffective and it does not decrease
the first-pass effect. IV administration will not compensate for
the patient's impaired renal function.
• Question 2
A patient is treated with an antibiotic for an infection in his leg. After 2

days of taking the antibiotic, the patient calls the clinic and reports that he
has a rash all over his body. The nurse is aware that a rash can be an
adverse effect of an antibiotic and can be either a biologic, chemical, or
physiologic action of the drug, which is an example of
Response

:
Pharmacodynamics is the biologic, chemical, and physiologic
actions of a particular drug within the body and the study of
how those actions occur, including adverse effects. It is how the
drug affects the body. The pharmacodynamics of a drug is
responsible for its therapeutic effects and sometimes its
adverse effects. Pharmacotherapeutics refers to the desired,
therapeutic effect of the drug. Pharmacokinetics is the changes
that occur to the drug while it is inside the body.
Pharmacogenetics is the study of how genetic variables affect
the pharmacodynamics of a drug in a specific patient.
• Question 3
A home health nurse notes that there have been changes to a patient's

oral drug regimen. The nurse will closely monitor the new drug regimen to
Response
Feedback
:
Changes in the drug regimen may cause changes in drug
absorption and thereby decrease the anticipated drug effect.
This decrease is due to the prevention of binding and loss of
absorption and overall drug effectiveness. A change in the drug
regimen would not help a nurse to track the route of
metabolism or determine the speed of chelation. If any adverse
effect were to occur as a result of a drug regimen change, it
would not necessarily be immunotoxicity; it could also be
nephrotoxicity, ototoxicity, or cardiotoxicity.

ggraded a The culture and sensitivity testing of a patient's wound exudate indicates
that a specific antibiotic is necessary for treatment. The United States
Pharmacopeia–National Formulary indicates that the drug in question is
96% protein bound. What are the implications of this fact?
Response
Feedback:
A drug that is 96% protein bound has only 4% of ingested
molecules free and active, a fact that is likely to necessitate a
high dose of the drug. This does not result in rapid absorption
and/or excretion and does not indicate a need for increased
protein intake.
• Question 5
A patient has been prescribed several drugs and fluids to be given
intravenously. Before the nurse starts the intravenous administration, a
priority assessment of the patient will be to note the

Response
Feedback
:
Baseline body weight and height, heart rate, and blood pressure
are all important considerations during the assessment of a
patient. However, if a patient has to be given drugs
intravenously, it is important to inspect the skin for rashes,
moles, or sores, so those areas can be avoided as an insertion
or injection site.
• Question 6
A 56-year-old female patient has been admitted to the hospital with
1 out of 1 points
chronic muscle spasms and has been prescribed a new medication to treat
the spasms. She has a poorly documented allergy to eggs, synthetic
clothes, and perfumes. What is the priority action of the nurse to ensure
that prescribed medication does not experience an allergic reaction?
Response
Feedback
:
The nurse should post an allergies notice on the front of the
chart and document the allergies in the appropriate area of the
patient's record; this will allow continuous access of the dietary
staff and the other members of the health care team to the
information and serve to limit errors. The prescriber would
always ask the patient about her allergies before prescribing a
new medication. The patient is not having an allergic reaction,
so treating her for an allergic reaction is unnecessary. If the
allergies are documented in the appropriate area of the
patient's record, the dietary staff will be aware that the patient
should not be served eggs.
• Question 7
In response to a patient's nausea, the nurse has mixed a dose of an
