MULTIPLE CHOICE
1. Which role in drug therapy is common to all prescribers, the nurse and the pharmacist?
a. Checking insurance coverage for the drug
b. Asking the patient about any known drug allergies
c. Teaching the patient about the specific drug prescribed
d. Ensuring that the drug does not carry a “black box warning”
ANS: C
Although the nurse spends more time with the patient and often has more opportunity for
teaching patients all about their prescribed drug therapies, this role is one that should be
performed by all prescribers and the pharmacist, as well as the nurse administering the drug.
Although asking the patient about known drug allergies is important, this is not an expected
role for the pharmacist or the person dispensing the drug.
DIF: Cognitive Level: Understanding
2. Which drug feature is most important for a drug to be classified as over-the-counter (OTC)?
a. Has a currently accepted medical use and is at least 50% effective.
b. Requires no adjustment in food or liquid intake for best absorption.
c. Is composed of naturally occurring substances rather than compounded from
chemicals.
d. Has a low potential for harmful side effects when taken at the recommended
dosage and schedule.
ANS: D
Drugs designated as over-the-counter (OTC) are weaker at a lower dosage and have less
potential for harmful side effects. They are available for purchase without a prescription and
are considered safe for self-medication when the package directions for dosage and schedule
are followed.
DIF: Cognitive Level: Understanding
3. Which drug feature is responsible for a drug or drug category being classified as a “high-alert
drug?”
a. The same side effects occur in almost all people who take or receive the drug.
b. The drug has an increased risk for causing a patient harm if it is used in error.
c. There is no oral form of the drug and it must be given intravenously (IV).
d. The drug is manufactured in a foreign country.
ANS: B

Chapter 01: Drug Therapy: Roles, Regulations, Actions, and Responses
A high-alert drug is one that has an increased risk for causing a patient harm if it is used in
error. The error may be a dose that is too high, a dose that is too low, a dose given to a patient
for whom it was not prescribed, and a dose not given to a patient for whom it was prescribed.
These drugs are often referred to as “PINCH” drugs, P = potassium, I = insulin, N = narcotics
(opioids), C = cancer chemotherapy agents, and H = heparin or any other drug that strongly
affects blood clotting.
DIF: Cognitive Level: Understanding
4. A patient is prescribed to receive 25 mg of a drug every 8 hours. How many total mg of the
drug will the nurse calculate the patient should receive daily?
a. 50 mg
b. 75 mg
c. 100 mg
d. 150 mg
ANS: B
There are 24 hours in a day. 24 hours divided by 8 hours is 3. Three times 25 mg is 75 mg.
DIF: Cognitive Level: Applying or Higher
5. What action or condition is a major disadvantage of the oral drug delivery route?
a. First-pass loss of drug is extensive.
b. The drug must be sterile rather than clean.
c. Only lipid-soluble drugs can be absorbed.
d. Adverse effects occur more rapidly than with other routes.
ANS: A
Drugs taken orally are absorbed by the gastrointestinal system into the blood. This blood
circulates first to the liver before going to any site of action (other than the blood). The liver is
a major processing site for metabolizing and eliminating the drug. Therefore, some drugs are
deactivated and their effectiveness is reduced by the liver. All oral drugs have less
bioavailability than drugs administered by other routes.
DIF: Cognitive Level: Understanding
6. Why is it important for the nurse to always ask a patient about his or her use of any herbal
supplements or botanicals?
a. Many states do not have regulations about herbal supplements or botanicals.
b. These substances are illegal and their use by patients must be reported.
c. Patients who use botanicals seldom take their prescribed drugs.
d. These substances can interact with a prescribed drug.
ANS: D
Many herbal supplements and botanicals have effects on cell activity. Sometimes these agents
can make drug side effects worse or can reduce the effectiveness of a prescribed drug. Others
can actually cause health problems.
