Which drug property is most enhanced by the presence of many different types of receptors
throughout the body?
A. Potency
B. Safety
C. Selectivity
D. Convenience - ANSWER ✔ - C. Selectivity.
Because each receptor regulates just a few processes, selective drug action is possible. Multiple
types of receptors do not have as much effect on potency, safety, or convenience.
The nurse practitioner prepares to give a drug that will prevent receptor activation. Which term
would describe this drug?
A. Antagonist
B. Selective
C. Agonist
D. Potent - ANSWER ✔ - A. An antagonist is a drug that prevents receptor activation. An agonist
is a molecule that activates receptors. A selective drug has only the desired response but may
not activate receptors. A potent drug requires a lower dose to achieve its effect.
The nurse is preparing to administer a drug with a high therapeutic index. What does this mean
about the drug?
A. It is very potent.
B. It has a low efficacy.
C. It is probably lethal.
,D. It is relatively safe. - ANSWER ✔ - D. It is relatively safe
Therapeutic index is a measure of a drug's safety. It is the ratio between the therapeutic and
lethal dose of the drug. A large or high therapeutic index indicates that the drug is relatively safe.
Not all drugs produce effects binding to a receptor. Which drugs do not act through receptors?
A. Antacids
B. Analgesics
C. Antihistamines
D. Steroid hormones - ANSWER ✔ - A. Antacids do not act through receptors. Antacids neutralize
gastric activity by direct chemical interaction with stomach acid.
A patient diagnosed with chronic pain calls to request an oxycodone (Oxycontin) refill. Which
action should the prescriber take initially?
A. Fax the renewal order to the pharmacy.
B. Arrange to schedule an appointment with the patient.
C. Verify the patient's adherence to the prescribed drug regimen.
D. Determine the patient's current medication dosage and pain level - ANSWER ✔ - B. Arrange to
schedule an appointment with the patient
Schedule II medications are not eligible for refills, and prescriptions must be handwritten or e-
scribed. It is important to verify the patient's adherence to the drug regimen and determine the
current dosage of medication and pain level; however, this can be accomplished by scheduling
an appointment and evaluating the patient in person.
The provider prepares a patient with newly diagnosed type 1 diabetes for hospital discharge.
Which action by the provider will best support the patient's ability to effectively manage
medication therapy?
A. Asking the patient to demonstrate how to measure and administer insulin
B. Discussing methods of storing insulin and discarding syringes
, C. Giving information about how diet and exercise affect insulin requirements
D. Teaching the patient about the long-term consequences of poor diabetes control - ANSWER
✔ - A. Asking the patient to demonstrate how to measure and administer insulin
Because insulin must be given correctly to control symptoms and prevent an overdose, it is most
important for the patient to know how to measure and administer it. Asking for a demonstration
of technique is the best way to determine whether the patient has understood the teaching. The
other teaching points are important as well, but they are not as critical.
A patient reports that a medication prescribed for recurrent migraine headaches is not working.
Which action is the prescriber's priority when addressing the patient's concern?
A. Ask the patient about the number and frequency of tablets taken.
B. Assess the patient's headache pain on a scale from 1 to 10.
C. Prescribe a new medication for migraine management.
D. Suggest biofeedback as an adjunct to drug therapy. - ANSWER ✔ - A. Ask the patient about the
number and frequency of tablets taken.
When evaluating the effectiveness of a drug, it is important to determine how often the patient
is using the drug. Asking the patient to identify how many tablets are taken and how often helps
the provider determine effective dosages and adherence to the medication regimen. The patient
has already stated that the medication is not working; the actual level of pain may determine the
degree to which it is not working, but it does not help the provider to determine why it is not
working. The assessment process should gather as much information about compliance,
symptoms, and drug effectiveness as possible before enacting a change in treatment.
Biofeedback may be an effective adjunct to treatment, but it should not be recommended
without complete information about drug effectiveness.
The drug manual states that older adult patients are at increased risk for hepatotoxicity. Which
action is most important when prescribing this medication to an 80-year-old patient?
