Introduction to Drugs Karch Pharmacology Ch. 1 :Questions and Answers
A nurse is assessing the patient's home medication use. After listening to the patient list current medications,
the nurse asks what priority question?
a. "Do you take any generic medications?"
b. "Are any of these medications orphan drugs?"
c. "Are these medications safe to take during pregnancy?"
d. "Do you take any over-the-counter medications?" - ansd.
It is important for the nurse to specifically question use of over-the-counter medications because patients may
not consider them important. The patient is unlikely to know the meaning of "orphan drugs" unless they too
are health care providers. Safety during pregnancy, use of a generic medication, or classification of orphan
drugs are things the patient would be unable to answer but could be found in reference books if the nurse
wishes to research them.
A nurse is instructing a pregnant patient concerning the potential risk to her fetus from a Pregnancy Category B
drug. What would the nurse inform the patient?
a. "Adequate studies in pregnant women have demonstrated there is no risk to the fetus."
b. "Animal studies have not demonstrated a risk to the fetus, but there have been no adequate studies in
pregnant women."
c. "Animal studies have shown an adverse effect on the fetus, but there are no adequate studies in pregnant
women."
d. "There is evidence of human fetal risk, but the potential benefits from use of the drug may be acceptable
despite potential risks." - ansb.
Category B indicates that animal studies have not demonstrated a risk to the fetus. However, there have not
been adequate studies in pregnant women to demonstrate risk to a fetus during the first trimester of
pregnancy and no evidence of risk in later trimesters. Category A indicates that adequate studies in pregnant
women have not demonstrated a risk to the fetus in the first trimester or in later trimesters. Category C
indicates that animal studies have shown an adverse effect on the fetus, but no adequate studies in humans.
Category D reveals evidence of human fetal risk, but the potential benefits from the use of the drugs in
,pregnant women may outweigh potential risks.
A nurse working in radiology administers iodine to a patient who is having a computed tomography (CT) scan.
The nurse working on the oncology unit administers chemotherapy to patients who have cancer. At the Public
Health Department, a nurse administers a measles-mumps-rubella (MMR) vaccine to a 14-month-old child as a
routine immunization. Which branch of pharmacology best describes the actions of all three nurses?
a. Pharmacoeconomics
b. Pharmacotherapeutics
c. Pharmacodynamics
d. Pharmacokinetics - ansb.
Pharmacology is the study of the biologic effects of chemicals. Nurses are involved with clinical pharmacology
or pharmacotherapeutics, which is a branch of pharmacology that deals with the uses of drugs to treat,
prevent, and diagnose disease. The radiology nurse is administering a drug to help diagnose a disease. The
oncology nurse is administering a drug to help treat a disease. Pharmacoeconomics includes any costs involved
in drug therapy. Pharmacodynamics involves how a drug affects the body and pharmacokinetics is how the
body acts on the body.
A patient asks the nurse, "What is a Drug Enforcement Agency (DEA) number?" What is the nurse's best
response?
a. "DEA Numbers are given to physicians and pharmacists when they register with the DEA to prescribe and
dispense controlled substances."
b. "Physicians must have a DEA number in order to prescribe any type of medication for patients."
c. "DEA numbers are case numbers given when someone breaks the law involving a controlled substance."
d. "DEA numbers are contact numbers to talk with someone at the DEA when questions arise about controlled
substances." - ansa.
All pharmacists and physicians must register with the DEA. They are given numbers that are required before
they can dispense or prescribe controlled substances. DEA numbers are only needed when prescribing
controlled substances. A DEA number is neither a case number nor a phone number.
, A physician has ordered intramuscular (IM) injections of morphine, a narcotic, every 4 hours as needed for pain
in a motor vehicle accident victim. The nurse is aware this drug has a high abuse potential. Under what
category would morphine be classified?
a. Schedule I
b. Schedule II
c. Schedule III
d. Schedule IV - ansb.
Narcotics with a high abuse potential are classified as Schedule II drugs because of severe dependence liability.
Schedule I drugs have high abuse potential and no accepted medical use. Schedule III drugs have a lesser abuse
potential than II and an accepted medical use. Schedule IV drugs have low abuse potential and limited
dependence liability.
After administering a medication, for what would the nurse assess the patient?
a. Drug effects
b. Allergies
c. Pregnancy
d. Preexisting conditions - ansa.
After the medication is administered, the nurse assesses the patient for drug affects, both therapeutic and
adverse. The nurse would assess the patient for allergies, preexisting conditions, and pregnancy before
administering a medication.
After completing a course on pharmacology for nurses, what will the nurse know?
a. Everything necessary for safe and effective medication administration
