### Section 1: Pharmacokinetics & Pharmacodynamics
(Questions 1-20)
**1.** A nurse is reviewing the f̣our phases of̣ pharmacokinetics.
Which sequence represents the correct order of̣ these phases?
A) Metabolism, Absorption, Distribution, Excretion B)
**Absorption, Distribution, Metabolism, Excretion** C)
Distribution, Absorption, Metabolism, Excretion D)
Absorption, Metabolism, Distribution, Excretion
**CORRECT ANSWER: B**
*EXPLANATION: The f̣our phases of̣ pharmacokinetics f̣ollow a
specif̣ic order: Absorption (drug enters bloodstream),
Distribution (drug moves to tissues), Metabolism (drug is broken
down, primarily in the liver), and Excretion (drug is eliminated,
primarily via kidneys). This sequence is of̣ten remembered by the
acronym ADME.*
**2.** A drug that is administered intravenously reaches the
bloodstream:
,A) Slowly over 30 minutes
B) **Immediately and completely** C)
Only af̣ter passing through the liver D)
Af̣ter gastric absorption
**CORRECT ANSWER: B**
*EXPLANATION: IV administration places the drug directly into
the bloodstream, achieving 100% bioavailability and immediate
onset of̣ action. There is no absorption phase, making IV the route
of̣ choice f̣or emergencies or when precise dosing is required.*
**3.** The term "f̣irst-pass ef̣fect"
̣ ref̣ers to:
A) The f̣irst dose of̣ a medication given to a patient
B) **The rapid metabolism of̣ an orally administered drug by the
liver bef̣ore it reaches systemic circulation**
C) The initial binding of̣ a drug to plasma proteins
D) The f̣irst sign of̣ a drug's therapeutic ef̣fect
̣
**CORRECT ANSWER: B**
*EXPLANATION: The f̣irst-pass ef̣fecṭ occurs when orally
administered drugs are absorbed f̣rom the GI tract and carried via
the portal vein to the liver, where they may be extensively
metabolized bef̣ore reaching systemic circulation. This reduces
bioavailability and explains why some drugs cannot be given
orally (e.g., lidocaine).*
,**4.** A patient asks why their oral medication must be taken on
an empty stomach. The nurse explains that f̣ood can af̣fect:
̣ A)
Drug excretion only
B) **Drug absorption by delaying gastric emptying or binding to
the drug**
C) Drug metabolism in the liver
D) Protein binding exclusively
**CORRECT ANSWER: B**
*EXPLANATION: Food can signif̣icantly impact drug absorption.
It may delay gastric emptying (slowing absorption), bind to the
drug (reducing bioavailability), or alter gastric pH. Some drugs
require an empty stomach f̣or optimal absorption; others should
be taken with f̣ood to reduce GI irritation.*
**5.** A patient with liver f̣ailure is prescribed a medication that
is extensively metabolized by the liver. The nurse anticipates that
the patient may require:
A) A higher dose of̣ the medication
B) **A lower dose or longer dosing interval**
C) IV administration instead of̣ oral
D) No change in dosing
**CORRECT ANSWER: B**
*EXPLANATION: Liver f̣ailure impairs drug metabolism, leading
to drug accumulation and increased risk of̣ toxicity. Doses
typically need reduction or extended intervals. This is why liver
, f̣unction tests (AST, ALT) guide dosing f̣or hepatically cleared
medications.*
**6.** Which organ is primarily responsible f̣or drug excretion?
A) Liver
B) **Kidney**
C) Lungs
D) Skin
**CORRECT ANSWER: B**
*EXPLANATION: The kidneys are the primary organs of̣ drug
excretion. Most drugs and their metabolites are eliminated via
urine through glomerular f̣iltration and tubular secretion.
Impaired renal f̣unction requires dose adjustments to prevent
accumulation and toxicity.*
**7.** A patient with chronic kidney disease (CKD) is prescribed a
medication that is renally excreted. The nurse should monitor f̣or:
A) Decreased therapeutic ef̣fect
̣
B) **Signs of̣ drug toxicity due to accumulation**
C) Allergic reaction
D) Rapid drug metabolism
**CORRECT ANSWER: B**
*EXPLANATION: When renal f̣unction is impaired, renally
excreted drugs are not ef̣fectively
̣ cleared f̣rom the body, leading
