NURS 6521 / NURS6521 Advanced Pharmacology Midterm Exam |
Question and Answers | Latest / Scored 99/100
• Question 1
1 out of 1 points
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 Impaired renal function will increase the half-life of drugs that are
Feedback:
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
1 out of 1 points
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
Feedback
:
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
1 out of 1 points
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 Changes in the drug regimen may cause changes in drug absorption
Feedback
:
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.
• Question 4
1 out of 1 points
, 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 A drug that is 96% protein bound has only 4% of ingested molecules
Feedback:
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
0 out of 1 points
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 Baseline body weight and height, heart rate, and blood pressure are
Feedback
:
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
1 out of 1 points
A 56-year-old female patient has been admitted to the hospital with 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 The nurse should post an allergies notice on the front of the chart
Feedback
:
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
0 out of 1 points
In response to a patient's nausea, the nurse has mixed a dose of an antiemetic
with 50 mL of sterile normal saline and will administer the dose by IV piggyback.
What is the rationale for the use of IV piggyback?
