NURS 6521 ADVANCED PHARMACOLOGY WEEK 1 QUIZ.
ACTUAL 2025 SUMMER QTR. (COMPLETE QUESTIONS AND
ANSWERS GRADED A+)
•
Tylenol 325 mg/tablet, patient needs 650 mg; how many tables should patient take?
2
Which of the following affects drug distribution throughout the body?
Protein binding
Response Both protein binding and altered pH of extracellular fluids affect drug
Feedback distribution. The presence of food in the gastrointestinal tract affects
: drug absorption, whereas an increase in hepatic enzymes affects drug
metabolism. High blood levels are not known to affect drug
pharmacokinetics.
•
A nurse is caring for a patient who has had part of her small intestine removed due to
cancer. She has also now developed hypertension and has been prescribed a new
medication to decrease her blood pressure. While planning the patient's care, the
nurse should consider a possible alteration in which of the following aspects of
pharmacokinetics?
Absorption
Response Because absorption takes place mostly in the small intestine, there
Feedback could be possible alterations with this process. Distribution takes place
: in the blood vessels; metabolism in the liver; and elimination via the
kidneys. Because these systems are not affected by her surgery, these
phases of pharmacokinetics would not be altered.
•
, A patient has a blood serum drug level of 50 units/mL. The drug's half-life is 1 hour. If
concentrations above 25 units/mL are toxic and no more of the drug is given, how
long will it take for the blood level to reach the nontoxic range?
Response Half-life is the time required for the serum concentration of a drug to
Feedback: decrease by 50%. After 1 hour, the serum concentration would be 25
units/mL (50/2). After 2 hours the serum concentration would be 12.5
units/mL (25/2) and reach the nontoxic range.
•
Which of the following statements best defines how a chemical becomes termed a
drug?
Response Even though all the responses are correct, a chemical must undergo a
Feedback series of tests to determine its therapeutic value and efficacy without
: severe toxicity or damaging properties before it is termed a drug. Test
results are reported to the FDA, which may or may not give approval.
•
A patient who has been admitted to the hospital for a mastectomy has stated that she
has experienced adverse drug effects at various times during her life. Which of the
following strategies should the nurse prioritize in order to minimize the potential of
adverse drug effects during the patient's stay in the hospital?
Response In an effort to minimize the potential of adverse drug effects, it is
Feedback necessary to closely monitor the patient. It would be inappropriate for
: the nurse to alter the route or frequency of administration or to
encourage herbal remedies that also carry the potential for adverse
effects.
•
A nurse who is responsible for administering medications should understand that the
goals of the MedWatch program are to (Select all that apply.)
Response The goals of the MedWatch program are to increase awareness of
Feedback serious reactions caused by drugs or medical devices, facilitate the
: reporting of adverse reactions, and provide the health care community
with regular feedback about product safety issues. The MedWatch
program does not accredit new medical facilities and hospitals. This is
the responsibility of JCAHO. MedWatch is not responsible for reporting
medication errors.
•
A nurse is discussing with a patient the efficacy of a drug that his physician has
suggested, and he begin taking. Efficacy of a drug means which of the following?
