CHAMBERLAIN NR 293 QUIZ 1 REVIEW | PHARMACOLOGY
CONCEPTS, PRACTICE QUESTIONS & ANSWERS
1. Describe the significance of the onset of action in determining the
effectiveness of a drug.
The onset of action is crucial as it indicates how quickly a drug can
provide relief or therapeutic effects to the patient.
The onset of action is irrelevant to the overall treatment plan.
The onset of action determines the dosage required for treatment.
The onset of action only affects the drug's side effects.
2. What term is used to describe the amount of drug present in a given volume
of plasma?
Therapeutic index
Drug concentration
Half-life
Bioavailability
3. Which of the following is the definition of contraindications?
Therapeutic effects of a medication
Circumstances under which it is appropriate to administer a
medication to a patient
Circumstances under which it is not appropriate to administer a
medication to a patient
Any actions of a medication other than those desired
,4. Which of the following is/are important methods to control TB?
Preventive treatment of contacts
at high risk infection
All of these are important methods of control
Provision of facilities for early treatment of cases and persons
Examination of patients, contacts, and suspects
5. Describe the significance of understanding contraindications in medication
administration.
Contraindications are the same as drug interactions.
Contraindications only apply to over-the-counter medications.
Understanding contraindications is crucial to prevent adverse
effects and ensure patient safety.
Contraindications are irrelevant to patient safety.
6. Describe how the First-Pass effect can influence the bioavailability of a drug.
The First-Pass effect only affects the distribution of a drug in the
bloodstream.
The First-Pass effect has no impact on the bioavailability of a drug.
The First-Pass effect increases the bioavailability of a drug by
enhancing absorption.
The First-Pass effect can significantly reduce the bioavailability of a
drug by metabolizing it before it enters systemic circulation.
7. What is the term used to describe the process of eliminating drugs from the
body in pharmacokinetics?
, Excretion
Metabolism
Absorption
Distribution
8. Describe how tolerance can affect a patient's medication regimen.
Tolerance indicates that a patient is allergic to the medication.
Tolerance can lead to the need for higher doses of a medication to
achieve the same therapeutic effect.
Tolerance ensures that a drug remains effective without any changes
in dosage.
Tolerance means that a drug's side effects will decrease over time.
9. Describe how an antagonist functions in the context of drug interactions.
An antagonist enhances the effect of agonists by binding to different
receptors.
An antagonist binds to receptors and prevents the activation by
agonists, thereby inhibiting the physiological response.
An antagonist has no effect on receptor binding and does not alter
physiological responses.
An antagonist increases the production of neurotransmitters,
enhancing their effects.
10. If a patient has a condition that affects their gastrointestinal motility, how
might this impact drug absorption?
It will only affect the drug's metabolism, not absorption.
, It will enhance the absorption of the drug, leading to increased
effects.
It may delay or alter the absorption of the drug, affecting its
therapeutic effect.
It will have no effect on drug absorption.
11. In a case where a patient is receiving primary treatment for tuberculosis, how
might a nurse implement supplemental therapy to improve the patient's
health?
The nurse should discontinue all medications to avoid interactions.
The nurse should increase the dosage of the primary medication
without consulting a physician.
The nurse might implement supplemental therapy by administering
vitamins or adjunct medications that support the primary
tuberculosis treatment.
The nurse should only focus on the primary medication without any
additional support.
12. What is the primary goal of palliative therapy in patient care?
To enhance drug absorption.
To provide preventive care.
To relieve symptoms and improve quality of life.
To cure the underlying disease.
13. Describe the role of hepatic metabolism in drug processing within the body.
Hepatic metabolism refers to the distribution of drugs throughout the
bloodstream.
